Cognitive Consequences of Forced Compliance by Leon Festinger and James Carlsmith was published in the 'Journal of Abnormal and Social Psychology.'
The premise for this classic piece of research was to test what happens to a person's private opinion when they are forced to do or say something contrary to that opinion. It was the first of numerous studies to corroborate the theory of 'cognitive dissonance.'

History of Psychology
The trial of U.S. v. Forty Barrels and Twenty Kegs of Coca-Cola began. This famous federal lawsuit filed against the Coca-Cola Company of Atlanta, Georgia under the 1906 food and drugs act alleged that Coca-Cola 'contained an added poisonous or added deleterious ingredient, caffeine which might render the product injurious to health.'
Prior to the trial the Coca-Cola Company called upon psychologist Harry Hollingworth for an opinion as to the influence of caffeine on mental and motor processes. In the absence of any reliable data on the subject, Hollingworth conducted a series of experiments to test the influence of caffeine on such things as perception and association, attention and judgment, steadiness, speed and coordination. Hollingworth testified that 'If the constant use of caffeine in moderate amounts would prove deleterious, some indication of such effect would have shown itself in the careful study of performance in tests covering a wide range of mental and motor processes.'
In the fourth week of the trial the case was dismissed, and for Coca-Cola, the rest, as they say, is history. By providing psychological information for the purpose of facilitating a legal decision, Hollingworth's testimony represents a landmark case in the history of forensic psychology. Hollingworth went on to become a renowned applied psychologist, conducting pioneering research within the field of industrial/organizational psychology and advertising. He was elected President of the American Psychological Association in 1927.

'The Authoritarian Personality' by Theodor W. Adorno, Else Frenkel-Brunswik, Daniel J. Levinson, and R. Nevitt Sanford was published. The research underpinning this classic text was based on the authors strongly held conviction that a clear correlation exists between deep-rooted personality traits and overt prejudice.
In order to measure these traits among the public the authors developed and introduced the 'California F Scale,' a scale which became so popular that the study of authoritarianism dominated research within social psychology throughout the 1950's.

'Art and Illusion: A Study in the Psychology of Pictorial Representation' was first published. Written by art historian Ernst Hans Gombrich, this classic text explores theories of visual perception and mental sets to examine the idea that 'making precedes matching.' Namely that an artist does not simply copy what they see in front of them, but rather draws upon and manipulates inherited 'schemata.'
Catherine 'Kitty' Genovese, a New York bar manager, was murdered as she returned home to the Kew Gardens section of Queens. On the 27th March 1964 the New York Times reported the crime under the headline '37 Who Saw Murder Didn't Call The Police.' The article began 'For more than half an hour 38 respectable, law-abiding citizens in Queens watched a killer stalk and stab a woman in three separate attacks in Kew Gardens.'
This infamous crime sparked years of research into the social psychology of helping; in particular bystander intervention and diffusion of responsibility. There is, however, real doubt as to the accuracy of the original version of events. In 2007, Rachel Manning, Mark Levine, and Alan Collins, authors of an article in American Psychologist, stated that 'there is no evidence for the presence of 38 witnesses, or that witnesses observed the murder, or that witnesses remained inactive.'
