Diabulimia

diabulimiaDIABULIMIA, also known as ED-DMT1 or Eating Disorder-Diabetes Mellitus Type 1, is a type of eating disorder that affects people with type-1 diabetes. People suffering from diabulimia deliberately restrict insulin in an attempt to lose weight. Although there is no distinct diagnostic code for diabulimia, in DSM-5, based on the eating disorder behavior and manipulation of insulin, diabulimia can present with features of both bulimia and anorexia. Diabulimia can be classified under Other Specified Eating Disorder (OSFED) in DSM-5.

Rumination Disorder

Rumination-disorderRUMINATION DISORDER, also known as rumination syndrome, is a rare and chronic eating disorder. Individuals with Rumination Disorder unintentionally and repeatedly regurgitate food before swallowing it again, chewing it once more or spitting it out. They often spit up food from their stomach; re-chew partially digested or undigested food unintentionally and either re-swallow or spit it out. As per the reports of the patients, since the food hasn’t yet been digested, it isn’t acidic, as vomit is and tastes normal. Rumination usually happens soon after eating, at every meal but it appears to be the result of increased abdominal pressure.

Interesting Facts about Human Memory

1. The human mind can form, amplify, or reinvent a memory.

2. Short term memory (STM) and long term memory (LTM) are two different types of memories. Short term memory can hold 7±2 things for up to 20 seconds. Information received from the environment, first passes through short term memory before it becomes the part of long term memory.

3. Humans start to form memories when they are in the womb. This memory is described as prenatal or fetal memory. Various experiments have revealed that babies are capable of remembering sounds that were played to them during pregnancy.

4. The storage capacity of the human brain is practically limitless. Human brain can store approximately 2.5 petabytes of data, which means that human brain has as much memory as the entire internet.

5. Apparently, aging does not seem to have any direct effect on memory. People experience memory loss during old age merely because they use it less as they age.

6. The human mind can remember things that didn’t even occur. This obvious recollection of something that one did not actually experience is known as false memory. This phenomenon was demonstrated in an experiment where the interviewer was successfully able to convince 70% of the participants that they had committed a crime, when, in fact, they had not.

7. In the absence of rehearsal, memories become harder to access, this means that memories, in actual, do not decay.

8. During jet lag, certain stress hormones are released, which have been found to damage the memory.

9. While a person is drunk, he or she is not capable of creating memories.

10. There is no specific region in the brain where a given memory exists. Instead, it is distributed in different regions of the brain.

11. Memory is reconstructed from distinct fragments in order to be recalled.

12. Human memories are prioritized by the emotions. Emotions attach new information and function as an indicator of significance. Memories that are emotionally intense can last longer in the mind and can be recalled much more clearly.

13. Procrastination is an important tool of memory. Not focusing on something actively gives the subconscious time to work on the ideas in the background while the person performs other things.

Bulimia Nervosa

bulimia purgingA potentially life-threatening eating disorder, BULIMIA NERVOSA is characterized by binge eating followed by purging. People with Bulimia Nervosa often eat a large quantity of food in one go. This binge eating episode accompanied by a sense of loss of control of the overeating process causes a feeling of guilt and recurrent inappropriate behavior intended to prevent weight gain. This phenomenon is called purging, which includes, in addition to the use of purgatives, such measures as dietary fasting, excessive exercising, use of laxatives or self-induced vomiting, and even taking of thyroid medication to increase metabolism.

Anorexia Nervosa

Thin womanA person suffering from ANOREXIA NERVOSA often experiences a strong fear of gaining weight which leads to a refusal to maintain a healthy body weight or adequate nutritional status. Anorexia nervosa is typically associated with an erroneous complaint of being fat; weight loss up to 85% of ideal body weight (IBW); disturbance of body image; and in post-menarcheal females, the absence of at least three consecutive menstrual periods. An individual suffering from anorexia follows extreme steps to maintain a low body weight. He or she may try to lose weight by excessive exercise, or by using laxatives and vomiting as measure to get rid of the food from the body. It is considered one of the deadliest psychiatric disorders. In the absence of effective treatment, around 20%, of the people with anorexia die.

 

The Lowball Technique

Handshake

THE LOWBALL TECHNIQUE was named after, and first studied in 1978 by the US social psychologist Robert Cialdini, who found it while he was being trained as a car salesman. A technique of persuasion, it refers to a technique to elicit and raise compliance. It is mostly employed in commercial dealings. The technique is often brought to use to persuade a prospective buyer to accept a request. The proposal is so appealing that the buyer accepts it. Then just before the offer is being finalized, the salesman will change the original offer and reveal the hidden-cost making the original proposal less appealing. But as, the buyer has already committed to the offer, he or she will feel compelled to accept the second offer as well.

Cialdini and other researchers did a field experiment where researchers at first tried to persuade students to agree to volunteer to serve as experimental participants; 56 per cent students agreed to participate in the study. They then told the volunteers that the study was scheduled for 7 a.m., and volunteers were given the opportunity to withdraw. However, none of them did, and 95 per cent of them actually turned up at the appointed time. On the other hand, when a control group were asked to participate and were told the unsocial timing of the experiment up front, only 24 per cent agreed to participate.

Pseudobulbar Affect

Arthur Fleck's uncontrollable laughterThose of you who have watched Joaquin Phoenix’s Oscar-winning performance in Joker, would agree that one of the most striking traits of Arthur Fleck’s character is his uncontrollable laughter. Although the movie never names the specific conditions Fleck is diagnosed with, his fits of laughter are likely based on a real disorder called pseudobulbar affect.

Pseudobulbar affect (PBA) or emotional incontinence is a condition characterized by episodes of uncontrollable laughing or crying or some other emotional displays. PBA may occur in people with neurologic disorder such as multiple sclerosis or brain injuries, or stroke. As the involuntary outbursts can last from seconds to several minutes at a time, PBA can feel extremely alienating for the person living with it. Patients may find themselves crying or laughing uncontrollably at something that is only moderately sad or funny, respectively. These laughing or crying periods not only land the patients up in uncomfortable situations, but are also exhausting and painful too. Severe symptoms of PBA can lead to embarrassment, social isolation, anxiety, and depression. The condition can be quite disruptive to the patient’s life but fortunately, it is treatable. As with any sharp shift in mood, the most important thing to do is consult a professional as soon as possible.

Alien Hand Syndrome

Alien Hand Syndrome (AHS) is a condition that involves uncontrollable hand or limb movement. Named after the title character in the classic 1964 film, the syndrome is also called Dr Strangelove syndrome. The afflicted person experiences his or her limb acting involuntarily, i.e., without conscious control; and therefore, when one hand is engaged, the other hand would begin and do something counter to the former. The person with AHS may sometimes reach for objects and manipulate them without intending to do so, even to the point of having to use the other hand (normal one) to bring the alien hand under control. AHS may occur in cases of tumor, stroke, or surgery affecting the corpus callosum, which connects the two hemispheres of the brain. It may also present in cases where a person has had the two hemispheres of their brain surgically separated—a procedure performed in extreme cases of epilepsy and epileptic psychosis to allay the symptoms. While damage to the left hemisphere of the brain affects the right hand, damage to the right hemisphere affects the left hand because each side of the brain controls movement on the body’s opposite side.

Pluralistic Ignorance

A herdd of sheepsPLURALISTIC IGNORANCE refers to a social-psychology phenomenon in which people in a group guess wrongly about the group’s beliefs and values. This term was created by Floyd H. Allport and Daniel Katz in the 1930s. Also described as “no one believes, but everyone thinks that everyone believes,” pluralistic ignorance is a bias about a social group, held by the members of that group. The members of the group mistakenly infer that they feel differently from other group members, even though they feel similarly. Therefore, in a certain situation, despite rejecting a norm personally, the individuals go along with it because they assume, erroneously, that most others accept it. This misconception of others’ values causes the group members to act in ways that differ from what they actually believe in. As an example, imagine yourself attending a difficult lecture in college. After finishing the lecture, the professor asks if there are any doubts or questions. But you, despite having questions, don’t raise your hand because no one else has, because you assume that all other students have comprehended the lecture well, which might be just a misconception. The bystander effect can also be explained on the basis of pluralistic ignorance.

Functional Fixedness

Functional fixedness HeartyPsychFunctional fixedness also called functional fixity or functional embeddedness is a type of cognitive bias, which causes an inability to solve a problem requiring the use of a specific object, the impairment being the result of recent use of an object for a different function, or by recent perception of the object performing a different function.

The phenomenon was first described in 1935 by the German-born US psychologist Karl Duncker, who experimented with five problems, including what he called the box problem in which three small-lighted candles were to be attached to a wooden door at eye level. The subjects were presented with many objects, including a matchbox containing matches, a similar-sized cardboard box containing small candles, and a third similar box containing thumbtacks. The solution was to empty the three boxes, to fix them to the door with thumbtacks, and to stand a lighted candle in each box. While only 43 per cent of Duncker’s subjects solved the box problem in that form, 100 per cent of a control group solved it when presented with the same objects but with the three boxes empty, thus avoiding functional fixedness arising from perceiving the boxes as containers of other objects.

Across all five problems, Duncker found that the functional fixedness of crucial objects reduced the number of solutions by almost a half. Duncker pointed out that the phenomenon applies not only to physical objects or tools, but also to mental objects or concepts. An English translation from Duncker’s classic article in German was published in the journal Psychological Monographs in 1945. Functional fixedness can hamper a person’s ability to solve problems.

Functional fixedness prevents people from finding novel ways of using the objects that are familiar for solving particular problems, for solving other problems that may arise. Children who are five or younger are not fixed, they come up with new ways to use familiar objects during play. As they grow they become functionally fixed as a result of adults correcting them. By practicing creative thinking, functional fixedness can be avoided.

Cognitive Dissonance

Cognitive Dissonance written on black backgroundWhen a person holds two or more contradictory or inconsistent beliefs, ideas, or values, he or she experiences a mental discomfort. This mental discomfort or psychological stress is described as COGNITIVE DISSONANCE.

A seemingly simple cognitive consistency theory was first introduced by the US psychologist Leon Festinger in 1957. The concept is related to the effects inconsistent cognitions i.e. knowledge or belief, has on a person. It is believed that, inconsistent or contradictory beliefs or ideas are very hard to maintain and often cause tension, which ultimately motivates a person to bring change in those beliefs or ideas. If both the beliefs or ideas in the cognition pair are in harmony they are considered consonant, if one of the beliefs in the cognition pair is opposite to the other, they are dissonant; and if they are neither in harmony nor converse of the other, then such beliefs are said to be irrelevant to each other.

A state of tension is created due to dissonance relation which, in turn, leads to three types of dissonance-reducing behaviors:

  • Changing one of the two perceptions or cognitions
  • Decreasing the perceived importance of dissonant cognitions
  • Adding further (justifying) cognitions

This may be better understood by the following example. A classic case of dissonance is a smoker who holds two beliefs, i.e., “I smoke cigarette” and “Cigarette smoking is injurious to health.” These two sets of information are mutually contradictory and will lead to a state to dissonance. Therefore, to reduce this dissonance, the person will chose one of the above-mentioned dissonance-reducing behaviors.

The Halo Effect

sun with halloThe Halo effect was first documented by the US psychologist Frederick Lyman Wells in a study of ratings of the literary merit of authors. The study was published in the Archives of Psychology in 1907. It is a form of cognitive bias in which a person, brand, or thing evaluated to possess one desirable or positive trait is consequently evaluated to possess many other desirable or positive traits. In person perception, it is a generalization from the perception of one prominent attribute to an impression of the personality as a whole, leading to inflated correlations between rated characteristics. In other words when a person or object is perceived to be good in one aspect, we generally perceive him/her to be good in other areas as well. The term is occasionally limited to occasions in which it leads to an overvaluation of the personality as a whole. In simple terms, your general perception of an individual as “He/She is good!” influences your perception of that person’s particular traits (“He/She is intelligent also!”). The term ‘halo error’ was introduced in 1920 by the US psychologist Edward Thorndike.

The Spotlight Effect

woman in spotlightThe Spotlight Effect is a cognitive bias that makes people believe that others notice them more than they actually do. In other words, spotlight phenomenon makes people overestimate the extent to which others notice, observe, or judge them and the extent to which others remember things about them. It is, in some cases, the major reason behind people getting self-conscious in a large gathering and sometimes, becomes the cause of social anxiety. It is found to be more prevalent among teenagers, who spent plenty of time thinking about how others will perceive them. The cause of the spotlight effect is the innate tendency to forget that even though one is the center of one’s own world, he or she is not the center of everyone else’s. The term was coined by Thomas Gilovich and Kenneth Savitsky. The phenomenon first appeared in the journal Current Directions in Psychological Science in 1999.
