Voodoo death, a term coined by Harvard physiologist Walter Cannon in 1942 also known as psychogenic or psychosomatic death, is the phenomenon of sudden death as brought about by a strong emotional shock, such as fear. The anomaly is recognized as psychosomatic in that death is caused by an emotional response—often fear—to some suggested outside force.
Voodoo death is particularly noted in native societies, and concentration or prisoner of war camps, but the condition is not specific to any culture or mentality.

In medicine, a nocebo [no-see-bo] reaction or response refers to harmful, unpleasant, or undesirable effects a subject manifests after receiving an inert dummy drug or placebo. Nocebo responses are not chemically generated and are due only to the subject’s pessimistic belief and expectation that the inert drug will produce negative consequences. In these cases, there is no ‘real’ drug involved, but the actual negative consequences of the administration of the inert drug, which may be physiological, behavioral, emotional, and/or cognitive, are nonetheless real.
An example of nocebo effect would be someone who dies of fright after being bitten by a non-venomous snake. The term ‘nocebo’ (Latin: ‘I will harm’) was chosen by Walter Kennedy, in 1961, to denote the counterpart of one of the more recent applications of the term placebo (Latin: ‘I will please’); namely, that of a placebo being a drug that produced a beneficial, healthy, pleasant, or desirable consequence in a subject, as a direct result of that subject’s beliefs and expectations. The term ‘nocebo’ can also refer to positive outcomes based upon the patient’s expectation of that outcome.

Birth order is defined as a person’s rank by age among his or her siblings. Birth order is often believed to have a profound and lasting effect on psychological development. This assertion has been repeatedly challenged by researchers, yet birth order continues to have a strong presence in pop psychology and popular culture. Alfred Adler, an Austrian psychiatrist, and a contemporary of Sigmund Freud and Carl Jung, was one of the first theorists to suggest that birth order influences personality.
He argued that birth order can leave an indelible impression on an individual’s style of life, which is one’s habitual way of dealing with the tasks of friendship, love, and work. According to Adler, firstborns are ‘dethroned’ when a second child comes along, and this may have a lasting influence on them. Younger and only children may be pampered and spoiled, which can also affect their later personalities. Additional birth order factors that should be considered are the spacing in years between siblings, the total number of children, and the changing circumstances of the parents over time.

Monosodium [mon-uh-soh-dee-uhm] glutamate [gloo-tuh-meyt] (MSG) is a seasoning salt and one of the most abundant naturally occurring non-essential amino acids. The glutamate of MSG confers the same umami (savory) taste of glutamate from other foods (e.g. meats, poultry, fish, eggs, dairy products, and kombu seaweed), being chemically identical.
Industrial food manufacturers market and use MSG as a flavor enhancer because it balances, blends and rounds the total perception of other tastes. Professor Kikunae Ikeda from the Tokyo Imperial University isolated glutamic acid as a new taste substance in 1908 from kombu, and named its taste ‘umami.’

A self-serving bias is attributing successes to internal factors and failures to external factors. This bias is a mechanism for individuals to protect or enhance their own self-esteem.
A student who attributes a good grade on an exam to his or her own intelligence and hours of studying but a poor grade to the professor’s poor teaching ability and unfair test questions is exhibiting the self-serving bias. Studies have shown that similar attributions are made in various situations, such as the workplace, interpersonal relationships, sports, and consumer decisions.

Mistakes Were Made (But Not by Me) is a non-fiction book by social psychologists Carol Tavris and Elliot Aronson, first published in 2007. It deals with cognitive dissonance (discomfort caused by holding conflicting ideas simultaneously), self-serving bias (attributing successes to internal factors and failures to external factors), and other cognitive biases (deviations in judgment), using these psychological theories to illustrate how the perpetrators of hurtful acts justify and rationalize their behavior.
It describes a positive feedback loop of action and self-deception by which slight differences between people’s attitudes become polarized. Topics covered include: the doomsday cult described in ‘When Prophecy Fails’; the MMR vaccine controversy and Andrew Wakefield; marriage; day care sex abuse hysteria and false memory syndrome, confabulation of autobiographical memory; George W. Bush and the Iraq War; Criminal interrogations, trials, and capital punishment; Mel Gibson; and Oprah Winfrey and her involvement in the James Frey controversy.

Madeline Levine, Ph. D., is a practicing psychologist in Marin County, California. She is the author of several non-fiction books: ‘Viewing Violence’ published in 1996, ‘See No Evil: A Guide to Protecting Our Children from Media Violence’ published in 1998, and ‘The Price of Privilege: how parental pressure and material advantage are creating a generation of disconnected and unhappy kids’ published in 2006. The first two books represent an analysis of the negative effects of media violence on child development.
Her third book is a study of the psychological ailments plaguing teens from affluent families. ‘The Price of Privilege’ is based not only on her 25 years of experience in treating such teens within Marin County (an affluent community within the San Francisco Bay Area) but also on her consultations with colleagues around the United States—particularly research psychologist Suniya S. Luthar — as well as her review of the contemporary psychological research on the subject. Her latest book is ‘Teach Your Children Well: Parenting for Authentic Success.’

Morton’s toe (or Greek foot) is the common term for the condition of a shortened first metatarsal (big toe) in relation to the second metatarsal. It is a type of brachymetatarsia (a condition in which there is one or more abnormally short metatarsals).
The name derives from American orthopedic surgeon Dudley Joy Morton. Although commonly described as a disorder, it is sufficiently common to be considered a normal variant of foot shape (its prevalence varies with different populations).

Mithridatism [mith-ri-dey-tiz-uhm] is the practice of protecting oneself against a poison by gradually self-administering non-lethal amounts. The word derives from Mithridates VI, the King of Pontus (modern-day Turkey), who so feared being poisoned that he regularly ingested small doses, aiming to develop immunity. Having been defeated by Roman general Pompey, legend has it that Mithridates tried to commit suicide using poison but failed because of his immunity and so had to resort to having a mercenary run him through with his sword.
There are only a few practical uses of mithridatism. It can be used by zoo handlers, researchers, and circus artists who deal closely with venomous animals. Mithridatization has been tried with success in Australia and Brazil and total immunity has been achieved even to multiple bites of extremely venomous cobras and pit vipers. Venomous snake handler Bill Haast used this method. Snake handlers from Burma tattoo themselves with snake venom for the same reason. Mithridatism is also used to treat peanut allergies.

Physiological tolerance or drug tolerance is commonly encountered in pharmacology, when a subject’s reaction to a specific drug and concentration of the drug is progressively reduced, requiring an increase in concentration to achieve the desired effect. Drug tolerance can involve both psychological drug tolerance and physiological factors.
Tolerance rate depends on the particular drug, dosage and frequency of use, though it is typically reversible. Physiological tolerance also occurs when an organism builds up a resistance to the effects of a substance after repeated exposure. This can occur with environmental substances, such as salt or pesticides. A rapid drug tolerance is termed tachyphylaxis.

Folk psychology can be described as the common understanding of mental processes (e.g. pain, pleasure, excitement, anxiety, etc.), grounded in the use of common linguistic terms as opposed to technical or scientific jargon. Folk psychology and analogy are invariably linked, with both concepts having evolved as a result of the relationship they have with each other. Once technical terms are stripped, the easiest way to describe something is through references to familiar items. In this way, the union between analogy and folk psychology was inevitable.
Traditionally, the study of folk psychology has focused on how everyday people—those without formal training in the various academic fields of science—go about attributing mental states. This domain has primarily been centered on intentional states reflective of an individual’s beliefs and desires; each described in terms of everyday language and concepts such as ‘beliefs,’ ‘desires,’ ‘fear,’ and ‘hope.’ As a result of this among other intrinsic factors, the domain’s scope, method, and contributions are consistently subjects of dispute in many scientific quarters.
