Maurice K. Temerlin (January 15, 1924 – January 15, 1988), was a psychologist and author. Life Research Suggestion Effects of Psychiatric Labels In the late 1960s and early 1970s, Temerlin published a series of articles examining the effect of diagnostic labels. Temerlin and his colleagues asked clinicians to evaluate and diagnose a man. Before making their diagnosis, they were told that an 'expert' had previously diagnosed the individual as 'psychotic'. The man was in fact a mentally healthy individual who was a confederate of the experimenters. Even though the man did not present with symptoms of psychosis, many clinicians agreed with the 'expert' diagnosis. Work with Lucy With his wife Jane W. Temerlin, Temerlin raised a chimpanzee named Lucy who was owned by the Institute for Primate Studies at the University of Oklahoma at Norman, Oklahoma. Temerlin and his wife raised Lucy in their home as if she were a human child, teaching her to eat with silverware, dress herself, flip through magazines, and sit in a chair at the dinner table. She was taught American Sign Language by primatologist Roger Fouts as part of an ape language project. Temerlin wrote the book Lucy: Growing Up Human: A Chimpanzee Daughter in a Psychotherapist's Family, analyzing the chimp's behaviour and describing her life. 'Psychotherapy Cults' Temerlin collaborated academically with his wife on articles, including "Psychotherapy Cults: An Iatrogenic Perversion," which was published in Psychotherapy: Theory, Research, and Practice. The work remains highly regarded, and is cited by numerous academicians, including Robert S. Pepper, Michael Langone, Guy Fielding and Sue Llewelyn, David A. Halperin, and Arnold Markowitz, and Dennis Tourish and Pauline Irving.
