Philip George Zimbardo (born March 23, 1933) is a psychologist and a professor emeritus at Stanford University.
 He became known for his 1971 Stanford prison experiment and has since authored various introductory psychology books, textbooks for college students, and other notable works, including "The Lucifer Effect", "The Time Paradox" and "The Time Cure".
 He is also the founder and president of the Heroic Imagination Project.
Walter Mischel (] ; born February 22, 1930) is an Austrian-born American psychologist specializing in personality theory and social psychology.

John Broadus Watson (January 9, 1878 – September 25, 1958) was an American psychologist who established the psychological school of behaviorism.
 Watson promoted a change in psychology through his address "Psychology as the Behaviorist Views it", which was given at Columbia University in 1913.
 Through his behaviorist approach, Watson conducted research on animal behavior, child rearing, and advertising.
 In addition, he conducted the controversial "Little Albert" experiment and the Kerplunk experiment.
 Watson popularized the use of the scientific theory with behaviorism.
 He was also editor of "Psychological Review" from 1910 to 1915.
 A "Review of General Psychology" survey, published in 2002, ranked Watson as the 17th most cited psychologist of the 20th century.
Norman Abeles (born April 15, 1928) is an Austrian-born psychologist.
 He is a university professor and a former president of the American Psychological Association.
Stanford Prison Experiment was an American punk band based in Los Angeles, California, whose name was a reference to the Stanford prison experiment conducted by psychologist Philip Zimbardo in 1971.
 The band represented various subgenres such as hardcore, post-hardcore, and grunge.
 Its leader learned about the SPE as an employee for the audio/visual dept at UCLA (He set up/played the film for a class).
The Stanford marshmallow experiment was a series of studies on delayed gratification in the late 1960s and early 1970s led by psychologist Walter Mischel, then a professor at Stanford University.
 In these studies, a child was offered a choice between one small reward provided immediately or two small rewards (i.e., a larger later reward) if they waited for a short period, approximately 15 minutes, during which the tester left the room and then returned.
 (The reward was sometimes a marshmallow, but often a cookie or a pretzel.)
 In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI), and other life measures.
The Rosenhan experiment was an experiment conducted to determine the validity of psychiatric diagnosis.
 The experimenters feigned hallucinations to enter psychiatric hospitals, and acted normally afterwards.
 They were diagnosed with psychiatric disorders and were given antipsychotic drugs.
 The study was conducted by psychologist David Rosenhan, a Stanford University professor, and published by the journal "Science" in 1973 under the title "On being sane in insane places".
 It is considered an important and influential criticism of psychiatric diagnosis.
The Stanford Prison Experiment is a 2015 American thriller film directed by Kyle Patrick Alvarez and written by Tim Talbott.
 The film stars Billy Crudup, Michael Angarano, Ezra Miller, Tye Sheridan, Keir Gilchrist, Olivia Thirlby, and Nelsan Ellis.
 The plot tells the story of the 1971 Stanford prison experiment conducted at Stanford University under supervision of psychology professor Philip Zimbardo in which students play the role of a prisoner or a prison guard.
Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide.
 This is often used for classroom demonstrations because it requires only a small number of ingredients and makes a "volcano of foam".
 This sometimes is known as the "Marshmallow Experiment", but is unrelated to the psychological Stanford marshmallow experiment.
The Stanford prison experiment (SPE) was an attempt to investigate the psychological effects of perceived power, focusing on the struggle between prisoners and Prison officers.
 It was conducted at Stanford University between August 14–20, 1971, by a research group led by psychology professor Philip Zimbardo using college students.
 It was funded by the U.S. Office of Naval Research as an investigation into the causes of difficulties between guards and prisoners in the United States Navy and United States Marine Corps.
 The experiment is a topic covered in most introductory psychology textbooks.
