Roland L. Fischer (born 1915, Budapest, Hungary - died in 1997 in Majorca, Spain[1]) was an experimental psychiatrist and psychopharmacologist known for his early work on schizophrenia, the perception-hallucination continuum model of altered states of consciousness, and for his work on gustation which later contributed to research supporting supertasting.[2]:226[3]:9[4] Fischer was formerly professor of experimental psychiatry and associate professor of pharmacology at Ohio State University (1958-1971),[5] and also held academic posts at George Washington University, Georgetown and Johns Hopkins University.[6]:13, 259–260

Life and career[edit]

Fischer was born in Budapest in 1915. Six months before the start of World War II in 1939, Fischer left Hungary to study chemistry at the University of Basel in Switzerland, where he received his Ph.D. in 1945.[5][7] Fischer was active between 1951 and 1977 and was the author of more than 350 publications.[6]:259[8] In the 1970s, Fischer was a lecturer in pharmacology at the George Washington University Medical and the Johns Hopkins Medical School and an editor for the Journal of Altered States of Consciousness. At this time, his interests involved biofeedback and EEG research on different states of consciousness.[7] In 1977, he retired to the island of Majorca where he died in 1997. In gratitude for the opportunities for engaging in teaching and research offered in his late days by the University of the Balearic Islands, he donated his personal collection of books to the library of the University of the Balearic Islands.[1][9]

Model psychosis hypothesis[edit]

Like German chemist Kurt Beringer (1893-1949) before him, Fischer began looking for an explanatory model of psychosis for schizophrenia in the late 1940s by comparing it to altered states produced by hallucinogens.[10]:226 In the 1950s, Fischer studied schizophrenia as a research biochemist at the University of Saskatchewan.[11] Fischer explored the model psychosis hypothesis of altered drug states originally studied by Beringer in 1927. Fischer and other researchers wondered if LSD could act as a chemical model for schizophrenia. However, as biochemical research progressed over time, the theory was rejected as newer evidence showed that both substance-induced psychosis and organic psychosis are remarkably different.

Taste science[edit]

In the 1960s, he helped contribute to research on gustation and is credited with discovering the association between the ability to taste PROP (6-n-propylthiouracil) with food preferences and body weight, and its relationship to alcohol use and smoking.[12] His early work in taste science contributed to later research on supertasting.[13]

Perception-hallucination continuum[edit]

Between 1968 and the late 1980s, Fischer developed a model for altered states of consciousness in several stages known as the perception-hallucination continuum. On one end of the continuum were ecstatic states, such as mystical rapture, separated by hyperaroused and hallucinatory states that schizophrenics might experience, followed by an aroused state, such as during creativity. Normal consciousness resides in the middle of the continuum. On the other end are the hypoaroused states, such as those experienced during samadhi, separated by tranquil states, for example during Zen meditation.[14][15][16]
