Candidates, superdelegates not lying, just forgetful
Recently, some presidential candidates have apparently forgotten something that others expected them to remember. Also some superdelegates have switched allegiance from one candidate to the other, revealing that they forgot the candidate they originally favored. However, others have claimed that the candidates or superdelegates had not truly forgotten anything. Instead, these critics have accused the candidates or superdelegates of lying when they said that they forgot something. This column examines instances of alleged poor memory or alleged dishonesty raised in three recent political controversies. You probably know this story but let me review it so we all begin on the same page. Hillary Clinton recalled in a recent campaign speech that she was fired upon by snipers when she arrived at an airport in Bosnia in 1996. She recalled further that she had to run to a vehicle for safety. Subsequently, a TV news channel found footage of video taken of the arrival mentioned by Ms. Clinton. The film clearly showed she arrived without sniper fire and, instead of making a rapid departure to a vehicle, the video showed that she experienced a somewhat prolonged greeting by a party of citizens and politicians. Shortly after the video was shown in news reports, some critics asserted that Ms. Clinton was lying about her encounter of sniper fire. Please don’t make inferences about my leanings one way or another regarding Ms. Clinton’s candidacy, but let me propose that Ms. Clinton was not lying. Instead her mistaken report about the Bosnia arrival was due to several weaknesses of human memory. First, liars have to have an excellent memory. If Ms. Clinton were a liar, she would have caught herself before she incorrectly recalled her Bosnia arrival story. Many of us (not necessarily you or me) are inclined to embellish on a story. However, if you or I were running for President, we would take care to not misspeak (and certainly not lie) about our past experiences because we want to avoid the pickle that Ms. Clinton got herself in. Second, Ms. Clinton’s memory failure appears to have been a blended memory. This is a kind of memory we all have sometime, In Ms. Clinton’s case, her memory appears to have been a blend of imaginations of a feared dangerous arrival and the real arrival. No doubt, highly visible people in politics worry occasionally about encountering dangerous situations. Consequently. it is plausible that she failed to distinguish between a real memory and an imagined one about what danger might have happened during her arrival. If you still are inclined to believe that Ms. Clinton was lying when she spoke about her Bosnia experience, recall that such disputes about past events is common between significant others, family and friends. For example, a voice emerges from the dining room. “Jack, it was not like that. How could you say that.” “Well Sally, you are the one who has it wrong. You never remember these things right.” And on it goes. Who can claim that their memory is totally above ever making such a mistake. Around the same time that Ms. Clinton was coping with the dispute about her memory for the Bosnia event, other critics were claiming that Barack Obama had not been telling the truth when he said that he had not heard anti-American statements made by his pastor in one or more sermons. Some critics claimed that it was impossible for Mr. Obama to regularly attend church and not remember offensive comments of his pastor. Please don’t make inferences about my leanings, one way or another, regarding Mr. Obama’s candidacy, but let me propose that Mr. Obama was not lying. Instead, his failure to remember his pastor’s sermons was due to several weaknesses of human memory. First, people in general have difficulty in noticing, much less remembering, comments that are contrary to their views. You and I usually do not register each and every comment that differs from our own viewpoint. Alternatively, we tend to remember the comments that support how we view things. Second, we tend to remember primarily the comments of honored figures that are consistent with their reputation. It stands to reason that Mr. Obama may not have paid attention to comments of his minister that were contrary to what Mr. Obama believes what his pastor would be expected to say. Everyone has an significant other, a family member, friend, or role model who sometimes says outlandish things. When the comments of a respected person are outlandish, we tend to ignore them - which is why we do not remember them. Third, remembering the sermons of anyone’s pastor, priest, or rabbi is extremely difficult because the experience each week has a lot in common with that of other weeks. We humans remember well unique events that occur in different locations at different times in the presence of different people - but not events that occur in the same seat, pew, or prayer position week after week. Who can remember each and every visit to the dentist or each and every visit to the local ice cream shop. Now lets turn to the memory and honesty of super delegates. Some of them have recently switched from being in favor of one candidate to favoring the other candidate. When they do so, have they forgotten their previous allegiance to the other candidate (or forgotten what the previous candidate did for the super delegate in the past)? Clearly the switch in candidates is not an aberration of memory. Instead, what has happened is that the supper delegate has evaluated the recent statements of each candidate and has decided to change his or her mind. We tend to remember events and information that gives us some peace, that achieves a balance between the positive and negative. In conclusion, instead of attacking candidates or super delegates for supposedly lying about what they remember or forget, lets focus on the issues and vote accordingly.

The advantages and disadvantages of memorists
Every family has one. Every group of friends has one, too: a person who tends to remember almost everything that is going on. This person knows all about upcoming events (concerts, lectures), what is at the movies, and what’s on TV. Sometimes, this person even knows what is going on among family members, friends and acquaintances. Accurate gossip is a valuable commodity. In the past century, a person with a great memory was called an mnemonist. However, we know now that an mnemonist really is not the right term for all people with an exceptional memory. A mnemonist is someone who is good at memorizing. The person who tends to remember everything going on is called, instead, a memorist. This person remembers without trying to memorize. Sort of how a fly sticks to fly paper, information about what is happening sticks to the memory of the memorist. This column describes, first, different aspects of the special powers of a memorist. from a technical perspective. Second, we will consider how memorists can be useful to themselves and others. Third, we examine some disadvantages of being a memorist. Special Powers of a Memorist Many experts have tested the memory powers of a memorist. When memorists have their memory tested, they will remember more than most people. For example, if this person is presented with a list to recall (say 30 unrelated words), he or she will remember more than 20 words while most other people will feel they have done well with recalling 15 words. If a memorist is given a digit span test (when a series of numbers, say a dozen, are said aloud by the test giver), he or she will recall as many as 10 or more digits. Most people with normal memory powers will recall around 7 numbers correctly. Testers may give a memorist a fluency test (in which this person is asked to recall as many items in a category in a short amount of time). For example, this person may be asked to recall as many animals as possible in a minute. When given this test, most people recall 10 or fewer animals. When a memorist is given this test, he or she is recalls more or much more that 10 animals. In contrast, when mnemonists are given memory tasks, they may do as well or even better than a memorist. However, mnemonists do these tasks differently than a memorist. As we considered in a previous column, mnemonists use well-practiced strategies when they perform a memory task. For example, to learn a list, they organize the words in their mind. When they learn a list of digits, they mentally convert the numbers presented into meaningful combinations. Suppose that a person is presented with the numbers 2961. The mnemonist may remember these numbers by converting them into years (1962) or into mathematical relationships (such as 21, 9 and 6, all of which numbers are multiples of 3). When recalling examples of a category, mnemonists try to recall examples of subcategories. For example, instead of recalling whatever animals that come to mind, the mnemonist will recall farm animals, then jungle animals, then pets and so on. A memorist does not use the memory strategies of an mnemonist. Nevertheless, he or she recalls more than most people. A memorist recalls something without use of strategies. They have an exceptional memory either because they are born that way or because they have had a lot of practice at memory tasks earlier in life. Mnemonists became good at memory tasks but only through making an effort to use strategies whenever they attempt such tasks. The Usefulness of a Memorist If you truly do have a memorist in your family or circle of friends, then you are very fortunate. With a memorist near by, there is no need to check the TV guide, newspaper or inquire with a friend about what is happening to others you know. If you recognize that someone in your family or circle of friends has the potential to be a memorist, encourage this person to become better and better at remembering. Each time he or she remembers some upcoming event, then reward this person. If you can nurture and train someone to be a memorist, then in the future you will not have to remember very much yourself. In other words, make a memorist your friend today. Disadvantages of Being a Memorist The memory powers of a memorist are not always a blessing. There are certain things that a memorist is likely to know and to not know. For example, memorists are usually skilled at remembering certain topics, such as facts about a sport such as baseball. However, just because the memorist knows the names of baseball stats backwards and forwards, does not mean that this person knows the names of the stars of other sports such as basketball, soccer, or rugby. Although it may seem that it would be great to be a memorist, sometimes it can have its drawbacks. Instead of recognizing that a memorist is a valuable resource of information, some deviants exploit memorists by making this person the target of devilment. For example, some people try to catch memorists not knowing something. “You don’t know the name of Andrew Jackson’s vice president? Your memory is not so good after all.” Consequently, if you know you are a memorist, you would be wise to hide it from those who might enjoy annoying you. Also, just in case you are wondering, there is no need to pursue such devilment with me. I am neither a memorist nor an mnemonist.

Drake sweeps ISU softball Friday, but Saturday's game called off
Home at last, but not home-free by any means. Indiana State’s softball team played 19 games before ever stepping foot on the Price Field diamond Friday for a doubleheader against Drake. The homecoming wasn’t a happy one — Drake swept ISU with 5-1 and 6-2 victories — but the long-term concern is on the mound, where star pitcher Darcy Wood is battling a shoulder injury. ISU's single game schedule for Saturday was canceled due to a Missouri Valley Conference wind-chill rule. Wood suffered the injury a few weeks ago, but has battled through the pain to post a 4-1 record, 2.87 ERA and 41 strikeouts going into Thursday’s contests. It was evident during Friday’s game, however, that Wood isn’t 100 percent and it concerns coach Brenda Coldren. Wood pitched the first game against the Bulldogs and didn’t pitch poorly. She struck out eight Bulldogs. But Drake was also able to take advantage of some pitches that might not have had the mustard on them they might have otherwise, and on a day when the wind was blowing straight out at a 20-mile-per-hour clip, that wasn’t a good thing for the Sycamores. “Darcy’s not up to 100 percent and that makes a big difference. Some of the balls she’s throwing have some movement, but it was a typical day for her in terms of making it move and the speed of the pitch,” ISU coach Brenda Coldren said. “It’s frustrating for her, because she’s used to being a different pitcher. She still struck out eight, but she’s not 100 percent.” Drake took a 1-0 lead in the first inning on a Kristen Faidley single to left. It remained that way for five innings, as the Sycamores could muster little against Drake starting pitcher Brynne Dordel. ISU had just two hits in the game, none in the first four innings. “We had problems adjusting. Their pitcher was a lot slower, and we’re usually aggressive, so we swung at a lot of bad pitches,” ISU second baseman Katie Iocoangeli said. “It was a good lesson for us going into [today’s] game.” ISU had four errors in the game, and another costly one occurred in the sixth inning, when Drake’s Elena Leon reached on a fielder’s choice and error by Christina Meyers. Two batters later, Drake’s Jenna DeLong pulled a two-run home run to left to make it 3-0. ISU answered in its half of the sixth on a RBI double by Britt Boyer, but the wind conspired to blow ISU down in the seventh. With a runner on, Faidley hit what would have been a medium-deep pop-out on a normal day, but the gale caught hold of it, and it just barely cleared the center field fence for a two-run homer. The errors that ISU committed in the first game came home to roost again in the second. Drake took a 5-0 lead in the second inning and ultimately chased ISU starter Megan McCurdy, but mistakes in the field ignited the rally. Leon scored from first on a dropped third strike after Drake’s Erin Mollohan whiffed. ISU catcher Audrey Childress tried to throw Mollohan out at first, but her throw struck the back of Mollohan’s helmet and the ball ricocheted into the outfield. After Susan Slycord knocked in another Drake run with a double, another ISU error by McCurdy on a fielder’s choice allowed Drake to score another run. A two-run double by Kristin Birocci capped Drake’s scoring and McCurdy was replaced by Katie Armour. “For as many people on our team that we have returning, we’re still young. We had a sophomore catcher make a bad decision on where to throw it, instead of getting herself in a good position, and we had a sophomore pitcher who made the right decision, but made a bad throw,” Coldren said. “We just weren’t sharp today.” ISU scored in its half of the second when Kelsey Anderson scored on an error by Drake’s Bridget Shields and got another run in the seventh on a RBI single by Meredith Simpson, but Drake’s five-run second inning was too much to overcome. Boyer and Leslie Fakes were the only Sycamores to get base hits in both games. ISU (8-13, 1-3) finishes its series with Drake (12-12, 3-2) at noon today at Price Field.

Completing a medical history form at a doctor’s office
These days, when you visit a doctor’s office for the first time, you are given a form on which you are supposed to record important facts about your medical history. Unfortunately, these forms ask for considerable information, much of which few human beings can recall. More unfortunate yet is that different doctors use different forms. Consequently, we are required to fill out medical history forms calling for essentially the same information all over again for each new doctor. This column examines the kinds of information needed to complete medical history forms and what to do when you cannot recall what you are supposed to recall. First we will describe the nature of medical history forms in doctors’ offices and how these forms challenge our memory. Second we will consider how to recall immunizations you have had. Third, we will address how to recall past medical problems including illnesses, diseases, disorders, and surgeries.
The Nature of Medical History FormsMedical history forms ask patients to record: what immunizations they may have had: and what medical problems they may have had (Illnesses, diseases, disorder and surgeries), along with the medications used to treat the medical problems. Also, the forms often ask when immunizations and medical problems occurred. In addition, different kinds of specialists want to know aspects of our history that other doctors could care less about. Obviously, it is in our best interest to avoid guessing and provide doctors with the most accurate information possible about our medical history. However, current customs do not lead patients to record the very best information on the medical history forms. For example, patients are often not required to bring documents to an appointment to verify all of the answers provided on a medical history form. Similarly, patients are usually not asked to verify their answers on the form with a relative or a friend. As a result, patients sometimes guess when answering the questions on a medical history form. Guesses do not help doctors and medical staffs treat patients. Given this situation, we should strive to recall the required information correctly. ImmunizationsIf you ponder long enough whether you have had a particular immunization, you might recall whether you actually had it. So sit in the most comfortable chair in the doctor’s waiting room. Relax all of the muscles in your body. Then let your mind drift back and back, way back. Imagine a day at preschool when a strange adult showed up in a white jacket. Imagine the pain you felt when you were inoculated. Remember screaming. Now try to recall the name of the immunization and when you had it. Hmmh. Lets try a different method. Sometimes we remember better if we are provided some clues. You know that many immunizations are given to young children. So you might try to figure out whether you had immunizations as a child for some of the following diseases: diphtheria, tetanus, whopping cough, polio, measles, rubella (German measles), mumps and polio. Also you might recall a rough date for when you had the immunization. If you think that you had one or more of these immunizations, chances are that you had them between 2 months and 6 years old because that is when most of these immunizations are given. Some immunizations, such as for hepatitis, pneumonia, and the flu, are usually given when we are older. If all attempts to recall an immunization fails, a popular answer is DNK (that is, you “do not know).” Medical ProblemsMany medical history forms ask whether you may have had one or more serious diseases or disorders, such as cancer, diabetes, heart disease, high blood pressure, kidney disease and others. Also history forms ask whether relatives have had these medical problems. You will also be asked to report any surgeries you have had. Chances are that you will recall your serious medical problems but if you are not sure that you have recalled all of these problems, a good way to get yourself to remember them is by sketching out a time-line of your life and by making notes by the year on the time-line when you had these medical problems. If you have difficulty recalling your surgeries, excuse yourself and go to the restroom where you can check your body for any scars from operations you may have forgotten about. Once you have a time line constructed for your medical problems, you also will be more able to remember medications you have taken for the medical problems you have put on your timeline. Finally, you can develop a relatively accurate medical history form if you go a little early to your first appointment with a doctor. Doing so will provide you time to concentrate, think of clues, and recall (or make an educated guess) about your history. Also, after you hand in your medical history form, ask a staff member there to make a photocopy of it. Later, update this completed form with any medical records you have and with what relatives and friends tell you about your medical history. Take this updated medical history form to future doctors appointments and it will be easy to complete the next medical history form. Someday a medical history database will probably be created that would hold the medical histories of all of us. Some hospitals and government medical systems have such a database now. There are forms on the web that could be used to record a person’s medical history and that could be stored in a database on the Web. Once there is a database accessible by doctors in general, we patients will not have to struggle to remember our medical history over again each time we visit a new doctor. We will have to make such a struggle with just the first from we complete.

Owls may get the credit for being wise, but you should want an elephant’s mind
Just to be clear at the outset, this column does not endorse or reject the symbol of a political party. Also, the column has nothing to do with a rock group called Elephant Memory that Yoko Ono and John Lennon promoted in the early 1970s. Instead, the topic of this column is the memory of real live elephants. First, we will examine whether elephants actually do have superior memory ability. Second, we will discover that whatever memory ability elephants have, it may be due to emotional trauma they have experienced. Third, we will examine the origins of the superiority of elephant memory. Along the way we will notice similarities between our memory and that of elephants.
The Superiority of Elephant MemoryA lot of folklore suggests that elephants have excellent memory powers. Many scientists have concluded that the folklore is correct. For example, research has demonstrated that elephants accurately remember over long intervals many other elephants, humans, places, skills, tones, commands, where they previously stashed food, and visual symbols. Some professionals who study or who take care of elephants have observed them recognize other elephants and people after not seeing them for as long as 30 years. Unfortunately, I have some information that may disappoint approximately 48 percent of readers. Researchers who have studied herds of elephants for years have concluded that it is the female of this species that has a superior memory. Keeping track of the members of their herds, female elephants acquire a superior social memory. Day after day, the females have to remember the young elephants and recognize the presence of predators. So it is the female elephant that never forgets. As for male elephants, they go off, leave most of the care of the young to the females, and just hang out with other male elephants. I suspect that this story may sound familiar to you. The Superiority of Elephant Memory and TraumaNow what I have to say is truly sad! Despite laws against doing so, poachers hunt elephants. The poachers can make substantial money by selling the hides of the elephants they kill. In addition, wild game managers have also been reported to sometimes shoot a stray elephant. The game managers do so in order to avoid having to go to the effort to return an elephant to its herd. In the past few years, increasing numbers of elephants have been attacking humans and destroying villages in Africa. Previously, attacks of elephants on humans were relatively rare and attributed to humans making use of land that elephants had occupied. However, the recent increase in attacks on humans by elephants has been attributed to the accurate memory of those elephants that survive the killing of poachers. Elephants who have survived presumably know that humans murdered their relatives and friend. They know this because they either witnessed the murder or recognized the scent of the poachers. Like humans, elephants are affected emotionally when a friend or relative dies. Elephants recognize when other elephants are dead. Sometimes they bury a deceased elephant to which they were related. Some researchers have proposed that the loss of friends and loved ones is so intense that the elephants experience post-traumatic stress disorder. Being depressed and grief stricken by their loss, elephants apparently seek revenge by indiscriminately killing the humans nearby. In some cases, the loss due to the killing of poachers is more than personal. When possible, the poachers search for, and kill, the largest elephants in order to have more hides to sell. Tragically, the loss of the largest elephant also means that the herd has less protection. In addition, poaching can seriously interfere with the management of a herd. Poachers sometimes murder the matriarch of a herd. The loss of the matriarch has serious consequences for the development of the young elephants in a herd. Matriarchs supervise other females in their raising of the young elephants. Without the matriarch, these younger females do not do as good a job raising the young elephants because these females the less experienced at motherhood than was the deceased matriarch. Because of having a poor upbringing, some young elephants develop poorly and acquired some bad behaviors. For example, the young elephants of herds that have lost their matriarch tend form gangs that are more prone to be aggressive and act violently toward humans. Origins of the Superiority of Elephant MemoryBesides gender and trauma, there are other reasons why elephants never forget. Elephants remember well because they may record their memories intelligently in the first place. Considerable evidence demonstrates that elephants are intelligent. For example, they communicate with a complex combination of sounds, chemicals, touch, movements, and use of their environment. Also domesticated elephants, such as those that belong to a circus, follow directions without difficulty. The ability of elephants to communicate in a complex manner may also be used to store memories of their experiences accurately in their long-term memory. In addition, elephants may not forget because, as they age, they acquire more and more experiences that prepare them to learn and remember new experiences more easily. In addition, elephants have large brains. This is not surprising, of course, given how large they are. In the final analysis, regardless of the superiority of an elephant’s memory, human memory may still be better. Despite their large size, the brains of elephants do not necessarily consist of more nerve cells than do the brains of humans. Those of us with more cells in our brains than the average elephant may remember better than this elephant. Also, elephants do not have their memory challenged as much as our memory is challenged. For example, elephants might not recognize as many members of their herd if they encountered them unexpectedly in a shopping center. Note: I thank Cherry Shellenberger for her valuable technical information on the memory of elephants.

Sometimes we fail to remember something and feel guilty
Guilt and memory failureSome people regard memory as an open or shut case. We either remember or don’t remember. For other people, memory involves three categories: remembering, not remembering, or not being sure whether we remember. However, we also have feelings about our capability to remember something. Sometimes we fail to remember and laugh about it. Other times we fail to remember and feel guilty about our failure (or at least we seem to be guilty). This column considers three issues about guilt when we forget. We will examine guilt for forgetting someone’s name, forgetting an appointment with someone, and when people fake feeling guilty for forgetting. Failing to remember someone’s name Some people believe that a person’s name is the sound he or she most enjoys hearing. This is what Dale Carnegie believed. This seems like a stretch to me. For example, I believe that the most precious sound is “here is the money I owe you.” Seriously, forgetting someone’s name is the memory failure that most adults find most annoying because guilt may be involved. The failure to recall someone’s name can make this person feel that we do not respect them or care for them. This is especially true if the name is for someone we are close to. For example, significant others get steamed if we do not recall their name. Worse yet, significant others get more than steamed if we call them by some other name than their own. However, a few years ago, a friend of mine pointed out that there are much worse memory failures than forgetting names. Forgetting to do something we promised to do for someone may convey regard as low or lower than forgetting someone’s name. Worse than forgetting a name, people may forget who someone else is. Perhaps forgetting a person’s identity conveys very low regard or lack of regard. But should people get hurt when someone forgets their name? At the moment of forgetting someone’s name, we may be distracted by our worries. Sometimes serious events occur in our lives. When this happens, there is little room left in our consciousness for trying to remember a name. I propose that when we forget a name at a time our life is collapsing around us, we should not feel guilty. I propose as well that the person who forgets a name should not be made to feel guilty. Alternatively, when someone forgets money they owe us, they should feel guilty. Forgetting an appointment Some people believe that the failure to make an appointment is also indicative of disrespect or lack of affection. After all, if someone cannot remember when to show up for an appointment, then it must be the case that this person does not value the appointment as much as other things that he or she could do at the time of the appointment. But is this conclusion really correct? A person may miss an appointment for some very valid reasons. A legitimate reason that leads a person to miss an appointment is when something comes up at the time he or she was to leave and go to the appointment. Sometimes the reason for missing an appointment is one that everyone would agree was legitimate. There are many events that pre-empt making an appointment: giving birth to a child, an emergency involving a good friend, a chore on which one’s life or comfort depends (such as picking up essential medicine), a fire at home or at work. Alternatively, some events legitimately pre-empt an appointment but we cannot tell the person whose appointment we missed because the reason for missing it is of a personal and private nature. For example, people may miss an appointment because they were given a speeding ticket, they were just served papers for a lawsuit, or they had been in an argument with their significant other. In any case, when we miss an appointment for good reasons that we may or may not want to talk about, we should not feel guilty. Falsely professing guilt for memory failureNow I would not do this and I know neither would you. Nevertheless, not assuming some guilt can on occasion offend another person. When people call someone by the wrong name, it is sometimes seen as insulting. When people make this mistake, they understandably may choose to look a little embarrassed. Also when forgetting an appointment is seen as insulting, people who have clearly forgotten an appointment also may choose to appear guilty. In both of these cases when a show of guilt may be called for, a person also may sincerely feel bad about the memory failure. Alternatively, a show of guilt for some memory failures is hard to believe. For example, some people claim to feel guilty because they forgot their New Year’s resolutions. Nevertheless, is guilt for such a memory failure credible? For example, we go all year long neglecting something (like our weight) or not doing something we should do (like exercise). Do we truly expect ourselves to turn over a new leaf and start a new life on Jan. 1st? I don’t think so, and I suspect, neither do you. A change in behavior requires much more than a resolution. A change in behavior requires considerable effort. Perhaps it would be good if we actually did feel guilty when we forget to live up to our New Year’s resolutions. If we actually were burdened by guilt for forgetting our resolutions, we would take steps to eliminate this guilt by making and remembering to keep them. But we know that in most cases, New Year’s resolutions are just fantasies (except for the approximately three of us for whom guilt is helpful).

A Sharper Mind: Benefiting from each others memory failures
We all are forgetful occasionally and leave something of ours behind in public places such as stores, shopping centers, and at the homes of family, friends and acquaintances. For example, we may forget to take with us things like a pair of gloves, an umbrella, a scarf or a jacket. Because we are all in this world together, we should forgive each other's memory failures. This column proposes that we establish a kind of universal agreement where we hope that some other soul can make use of what we have lost. Additionally, this agreement also means that we should make good use of things we find when the owner is unknown. We certainly should not throw such things away. This column will, first, examine what kinds of things are lost that we may find and make use of. Second, we will note that Lost and Found Offices sometimes have sales of things that they have held for months or years. Third, we will review the ethics of making use of lost things. Exchange of Common Things When you lose a pair of gloves, an umbrella, a scarf or a jacket, don’t fret too much about it. You can be confident that someone else will make use of your forgotten thing. On the other hand, if you have lost any of these things, you can always go and buy a replacement. However, you do not necessarily have to buy a replacement. You can find what you need among the things lost by others. Need an umbrella? Put an umbrella stand by your door. You will discover after a period of time several umbrellas growing out of your stand; people often forget to take their umbrella with them. If you can’t afford an umbrella stand, visit a college campus after a storm and you will find umbrellas lying about. Need a pair of gloves, a scarf or a jacket? Put a clothes tree or coat hooks by your front or back door. Sooner or later, someone who visits you will forget and leave a scarf or even a jacket. Again visit a college campus at the beginning of spring, late in the day when the weather has changed from cold to warm. Wander through the student center or the buildings with classrooms. Late in the day these places will be almost empty except for gloves, scarves and jackets left behind. There is a good chance that you will find what you need. College students (and their teachers) have a good memory for their courses (if they want). However, they are very forgetful of their accessories, not to mention their notes and books. If you have large pot luck parties, some people will forget to take home the food and refreshments they brought. If many people attended, then it is nearly impossible to know who left what food and drinks behind. Wait a few days or even a week; if the owner does not call and ask to pick up what they left, you can assume that you can use what was left. Lost and Found Offices. You can find Lost and Found offices in lots of places: colleges, libraries, bus stations, train stations, airports, golf courses, tennis clubs – even shopping centers. Such offices exist because of our forgetful nature. Our inclination to be forgetful is so bad that we often forget where we left something – or even that we left something. If we forget where we left something, we obviously will no longer have it and it may end up in a lost and found. Some lost and found offices put up conspicuous signs with lists of lost objects to remind owners that these offices hold these objects. However, when some people realize that a lost and found office may have what they lost, they still will not retrieve their lost possessions there because doing so would involve admitting to a memory failure. Because of our fragile memory ability – or pride about not admitting to a memory failure, Lost and Found offices overflow with lost belongings. When objects remain in a lost and found office unclaimed for weeks, months or years, the managers of the office conclude that no one will ever come for these things. To find space for newly lost items, some lost and offices will periodically throw away things that have been there for a long time. Sometimes other offices will hold sales for these things. Usually, these sales offer lots of bargains. Keep your eye out for notices about the sales of Lost and Found offices. These sales are usually not well advertised, so it is a good idea to ask a Lost and Found office when they anticipate holding a sale. Ethics of Acquiring Lost Objects Of course, there is a code of ethics about the use of lost items. If a pair of gloves, an umbrella, scarf or jacket has a nametag, we are obligated to contact the owner. We would want others to do the same when they find something that we have lost. However, if a lost item does not have a nametag, the finder might as well put it to good use. If a person recognizes a lost thing that you now use as actually belonging to him or her, you would – of course – turn it over to the owner. But because memory is often poor for possessions like gloves, umbrellas, scarves or jackets – or because people are often too proud to admit that they forgot something and left it behind – you most likely will be able to keep the found item. If you think that the owner might return to try to find what was lost, put a notice near where you found the item that you found it and your contact information. If you get no calls for a month or two, you might as well use the jacket, umbrella or gloves. Note: I thank Charles Hopkins, ISU Emeritus Professor of Education, for advising me on the topic of lost umbrellas.

Don’t let others profit from your memory failures
We all are forgetful on occasion. Some of us are more forgetful than others. If our forgetting inconveniences someone else, we hope that they will not be angry and will forgive our lapse. However, in addition to the possible anger or forgiving, there is another way someone might respond to our memory failure. Some people may choose to profit from our lapse. This column will examine how we can keep others from doing so successfully. A common way others may take advantage of us when we forget involves borrowing and lending. We will examine three ways others can profit if we forget to return what we borrowed or forget to get others return what we lent them. First, we will consider the advice to never borrow or lend, and how doing so protects us from others exploiting us when our memory fails. Second, we will consider how to protect us when circumstances compel us to borrow something from someone. Third, we will consider how to protect us when circumstances compel us to lend something to someone.
Never a Borrower or Lender Be In about 1841, Ralph Waldo Emerson recommended that we never borrow money or things from other people. He also recommended that we never lend things to others. He made these recommendations for a couple reasons. He advised not borrowing so that we would not take on too much debt. He advised not lending so that we would not lose what we own to others. However, in my opinion, Emerson was also thinking of the weakness of human memory and how we may forget our borrowing and lending. If we borrow some thing or some money and we forget to return it, we may be embarrassed when we are reminded that we have not returned what we borrowed. Failure to pay one’s debts is considered irresponsible and can even lead to legal problems. Alternatively, if we lend some money or some thing and forget having made this loan, we may never get back what we loaned. This may happen ifs the person has a bad memory too and forgets as well to return what we loaned them. Unavoidable BorrowingDespite trying to not borrow from others, we sometimes are in a situation where we need some thing or some money and we have to borrow it. For example, we might feel we have an immediate need for some cash or we will suffer negative consequences. In such a difficult situation, we may feel that we have to ask for a loan. For example, suppose we need a quarter to put in the parking meter in order to park our car and to go to an important meeting that is starting in five minutes. We discover that we don’t have a quarter but someone with us does and offers it to us. If we don’t accept this loan, we will have to find another parking spot farther away and be late for the meeting. Who among us would not take the quarter and feed the meter. However, accepting this loan requires us to remember to repay this loan in a timely manner. Some people, if dishonest, may see an opportunity to take advantage of someone who has borrowed something. Someone who is dishonest and who knows our memory is poor may later tell us that we actually owed them a dollar and a quarter. If this person is a good liar, they might say that we also borrowed a dollar that day for lunch. If enough time has passed, we might be unsure of just how much we borrowed on an occasion because it occurred quite a while ago. Who among us would be certain of the exact amount of money we borrowed on some occasions in the distant past. If we believe what this (dishonest) person tells us, we will pay them the extra dollar and they will have profited from our poor memory. Unavoidable LendingSometimes we know that someone else is in a jam. For example, we know a person who has an important meeting and this person desperately needs a quarter to put in a parking meter. If we have a quarter, who among us would not offer it as a loan so that this person could park and make his or her meeting? Of course, having made this loan entitles us to later to ask this person, often repeatedly, to give the quarter back to us. Unfortunately, if the person to whom we loaned money is dishonest, and we forget having made this loan, then this person may deliberately “forget.” In the case of the parking meter example, the person is a little richer (albeit, only 25 cents). Deliberate forgetting of debts and loans is a kind of stealing. People who do this are con artists where the con involves memory. Professionals in this form of theft know a lot about the psychology of memory for debts and loans. For example, they know that loans for change are forgotten more easily than loans for a number of dollars. Similarly, they also know that small loans are forgotten more easily than large loans. This principle can be extended to objects. Loans of inexpensive objects (a hammer, a pad of paper) are forgotten more often than expensive objects (for example, a vacuum cleaner, a tape recorder or ipod). Unfortunately, it is doubtful that memory con artists will ever be arrested and sent to jail. They have a perfect defense: they will invariably say that they, like others, forgot the debt or loan. So when borrowing and lending is unavoidable, take care to remember the debt or loan. Notes are the best way to keep from being the victim or a memory con artist. So, to keep track of your debts and loans, write them down as soon as possible and keep these notes someplace safe.

A Sharper Mind: Learning how to get a bright idea
In the past, this column has discussed the factors that facilitate problem solving and critical thinking. For example, such factors include understanding a problem in the first place, ignoring solutions tried previously, avoiding being fixated on a solution to a similar problem and by overloading one’s brain. In this column, we will consider a special kind of problem: coming up with a bright idea — one that will come up with the big idea that will solve some problem important to you, society, or your significant other Bright ideas are ones that solve a problem that is important to you and has resisted solution. Some bright ideas are famous, such as the invention of the light bulb by Edison (certainly a bright idea, no joke intended). Some bright ideas address mundane problems (such as how to make a certain appliance work). If you learn something from this column that makes you a lot of money, there is no need to mail some of it to me (although I am not opposed to you doing that); just give it to your favorite charity. Here we first discuss what defines a solution as bright. Then we will examine a couple of formulas for coming up with this kind of idea. Finally, we will consider the bottom line of a bright idea, whether it is truly useful. What is a Bright Idea? When someone comes up with a bright idea (such as writing this column on this topic), it is generally regarded as creative. One characteristic of a creative idea is that it is deviant. By deviant, I mean that the idea is unusual. No one else has thought of the creative idea before. Unfortunately, deviance is not sufficient for making an idea bright. The other critical characteristic of a bright idea is that it is useful. Obviously an idea is not bright if it does not solve a problem. Interestingly enough, ideas can be misleading in this regard. An idea may seem to be useful in some situations but later turn out to be useless or even counterproductive. Incubation Theory This theory holds that bright ideas originate in our unconscious. We are conscious that we have a problem but we are not conscious of its solution. (If we are conscious of its solution, a problem no longer exits.) The solution comes about magically because our mind works on the problem unconsciously until it develops a solution. The development of a bright idea occurs much like baking a cake. Another analogy is the creation of a child in the womb. The bright idea is borne out of a process of incubation that comes up with the solution. Once the solution is conceived, it emerges out of the unconscious into the light of conscious thought. Of course, sometimes nothing comes out of the incubation process. Consequently, people have attempted to formulate procedures that make it more likely that incubation will produce a bright idea. Different procedures have been proposed for making incubation work. One well-known theory advises that we immerse ourselves in all information that is relevant to the problem and then move on to doing other unrelated things. If we have done a good job of preparing our unconscious and if our unconscious is as ingenious as we suspect, a bright idea will eventually emerge. Another procedure for rendering a idea bright is to sleep on it. Again we begin by immersing ourselves in all relevant information about the problem. Then we go to sleep. With luck, we wake up with the solution. Sometimes when we sleep on an idea, we may have a dream that includes the solution. Sometimes the solution will come to us while we are partially awake. For example, a solution can come while drowsy — when we are not fully conscious as we got to sleep or as we awake. Because drowsiness can lead to bright ideas, daydreams are also known to prod an idea out of us. A more deliberate way to generate a bright idea is brainstorming. With this procedure, we devote time to trying to think of all kinds of solutions to a problem. Brainstorming supposedly works best when we attempt to wildly generate ideas with others, such as colleagues, friends and family in order to produce the solution. Usefulness theory The funny thing about ideas is that they sometimes feel like they are bright (or that we are bright) but it turns out that we were wrong. Sometimes we have the feeling that we are brilliant because we have come up with a bright idea. Unfortunately, that feeling can be an illusion. The only way we can be sure that an idea is bright is by testing it. Unfortunately, some bright ideas are only just that — bright — but actually not useful. There are many examples of seemingly bright ideas that turn out not to be bright. Chamberlain, a former prime minister of England, thought he had conceived of the bright idea to save England from Hitler’s war machine by getting Hitler to agree to a treaty that promised peace to England. Well, we know now that his idea was not so bright. Another example of a seemingly bright idea is the prefrontal lobotomy. When it was first proposed to the world, the prefrontal lobotomy was held as a cure for the severe mental illness of schizophrenia. Later it was discovered that the prefrontal lobotomy did not cure schizophrenia. It did keep people from exhibiting bizarre behavior but it did so by turning a person into a vegetable. Consequently an idea that seems bright in the first place may turn out not to be so bright with the passage of time.

A Sharper Mind: Reminiscences of meals past
Much of our lives are spent eating. As a result, we have many memories of breakfast, lunch or dinner, as well as for in between snacks. Sometimes we may want to remember what we ate on a certain occasion. This column considers what is the best way to recover the memory of what was eaten. Some people claim that the sense of smell is the most powerful aid to memory. A French author, Marcel Proust, claimed that the smell of a certain cake activated a memory from his youth of a similar cake prepared by his mother. He claimed that the smell of the cake transported him back in time to when he enjoyed this cake with his mother. Proust's account of his smell experience has been cited by many people as demonstrating that smell provides the quickest access to our memory of food and the past in general. Alternatively, other people feel that taste is more important to meal memory. Reminisce on the last steak, apple pie, or soup you had. Chances are that your reminiscence will focus on taste. So it might be plausibly argued that taste is more memorable than smell. But is it the smell or the taste that elicits memories? This column examines which of these two senses results in a richer and more durable memory. Some people might feel that the answer to this question will primarily be of interest to cooks and chefs. But it also is important to any of us who cherish the memory of meals past. Below, we will consider the memorability of smell, then taste, and then flavor (which is the combined effect of a food’s smell and taste). Smell The smell of food can activate memories of meals long forgotten. Smells can elicit a meal memory, even in the absence of a taste. There are a couple of reasons why smells are memorable. Smells elicit the memories of meals because the perception of smells is very accurate in the first place. The chemical receptors in the nose are specific to different odors. In addition, the power of smell to elicit memories also can be attributed to the fact that neural connections from the sense receptors in one’s nose to the perception center of the brain are shorter than the neural connections of other senses to this center. The memories elicited by a smell are often vivid, clear and striking. Leaving food aside, smells activate all kinds of memories. For example, perfumes catch one’s attention and remind one of past interactions with the person who wears the perfume. Similarly, the exhaust of cars and factories can be recalled (us Hauteans are well aware of industrial odors). A lot of research has been done on smell by humans. This research confirms the observation that smell alone activates memories easily. However, you should know that there is a drawback to this power of smell. Smells tends to stimulate the recall of just certain memories. For example, the smell of roast chicken may take you back mentally to a certain meal in your past. However, if you are trying to remember another meal when you had roast chicken, you may be drawn to other meals of roast chicken that you have had. Consequently, a smell cannot be depended on to activate the memory of the roast chicken that you want. Taste By itself, taste is not a very good cue to one’s memory of a meal. Recall the difficulty of tasting something when you have a cold. Taste is not a very good cue to memory for a few reasons. To begin with, taste does not elicit meal memories very easily because its perception is not very accurate in the first place. You may know that different parts of the tongue are responsible for certain tastes. Recent science says that the localization of taste on the tongue is not as precise as once thought. Instead, the taste of something we have eaten involves all areas on the tongue. Also, the degree and kind of stimulation of the tongue depends on how much one is salivating. Variation in the degree and kind of stimulation leads to differences in what taste is registered in memory. Later, when we try to remember something eaten, our success at remembering will depend on whether the taste present in our mouth matches the original taste. In addition, taste is not very effective in eliciting memories because the neural connections from the sense receptors in one’s tongue to the perception center of the brain are longer than the neural connections of the sense of smell. An exception to the poor memory for taste is poison. For example, rats (the rodent kind) quickly register in memory that a certain taste was experienced just before having the awful feeling that occurs when being poisoned. Rats (and people) who survive being poisoned acquire a taste aversion — the tendency to avoid the taste of poisoned food. Unfortunately, we do not know as much as we would like about taste aversion in humans. Most research on memory for taste has been done with rats because it is difficult to recruit humans for research on taste aversion. Flavor Because flavor results from the combined effect of smell and taste, it provides a powerful stimulus for memory. As a rule, two cues to memory are better than one. Together, smell and taste cues allow for more variety in the nature of memories remembered. Proust wrote that it was the smell that elicited the memory of his mom’s cake. However, it is likely that both taste and smell would have elicited his memory of her cake better than smell alone. If he had had a cold that day, he probably would not have even thought about her cake — no matter how delicious it was.
