“Harry Frederick Harlow (October 31, 1905–December 6, 1981) was an American psychologist best known for his maternal-separation and social isolation experiments on rhesus monkeys, which demonstrated the importance of tangible affection in social and cognitive development. He conducted most of his research at the University of Wisconsin-Madison, where humanistic psychologist Abraham Maslow worked for a time with him.
Harlow’s experiments were controversial, and as a result, his research was influential to many in the animal rights movement. Deborah Blum’s The Monkey Wars describes the influence of Harlow’s research on the burgeoning animal rights movement and subsequent improvement of research animal treatment.” <more>
“Carl Gustav Jung (26 July 1875 – 6 June 1961) was a Swiss psychiatrist, an influential thinker and the founder of Analytical psychology. Jung’s approach to psychology has been influential in the field of depth psychology and in countercultural movements across the globe. Jung is considered as the first modern psychologist to state that the human psyche is “by nature religious” and to explore it in depth. He emphasized understanding the psyche through exploring the worlds of dreams, art, mythology, religion and philosophy. Although he was a theoretical psychologist and practicing clinician, much of his life’s work was spent exploring other areas, including Eastern and Western philosophy, alchemy, astrology, sociology, as well as literature and the arts. His most notable ideas include the concept of psychological archetypes, the collective unconscious and synchronicity.” <more>
“Burrhus Frederic Skinner (March 20, 1904 – August 18, 1990) was an American psychologist, author, inventor, advocate for social reform, and poet. He was the Edgar Pierce Professor of Psychology at Harvard University from 1958 until his retirement in 1974. He invented the operant conditioning chamber, innovated his own philosophy of science called Radical Behaviorism, and founded his own school of experimental research psychology—the experimental analysis of behavior. His analysis of human behavior culminated in his work Verbal Behavior, which has recently seen enormous increase in interest experimentally and in applied settings. He discovered and advanced the rate of response as a dependent variable in psychological research. He invented the cumulative recorder to measure rate of responding as part of his highly influential work on schedules of reinforcement. In a recent survey, Skinner was listed as the most influential psychologist of the 20th century. He was a prolific author who published 21 books and 180 articles.” <more>
