possible unadjustment of the culture itself". In the 1950s new psychiatric drugs, notably the antipsychotic chlorpromazine, slowly came into use. Although often accepted as an advance in some ways, there was opposition, partly due to serious adverse effects such as tardive dyskinesia, and partly due their "chemical straitjacket" effect and their alleged use to control and intimidate patients. Patients often opposed psychiatry and refused or stopped taking the drugs when not subject to psychiatric control. There was also increasing opposition to the large-scale use of psychiatric hospitals and institutions, and attempts were made to develop services in the community. According to the Encyclopedia of Theory and Practice in Psychotherapy and Counseling, "In the 1950s in the United States, a right-wing anti-mental health movement opposed psychiatry, seeing it as liberal, left-wing, subversive and anti-American or pro-Communist. There were widespread fears that it threatened individual rights and undermined moral responsibility. An early skirmish was over the Alaska Mental Health Bill, where the right wing protestors were joined by the emerging Scientology movement." The field of psychology sometimes came into opposition with psychiatry. Behaviorists argued that mental disorder was a matter of learning not medicine; for example, Hans Eysenck argued that psychiatry "really has no role to play". The developing field of clinical psychology in particular came into close contact with psychiatry, often in opposition to its methods, theories and territories. 1960s Coming to the fore in the 1960s, "anti-psychiatry" (a term first used by David Cooper in 1967) defined a movement that vocally challenged the fundamental claims and practices of mainstream psychiatry. While most of its elements had precedents in earlier decades and centuries, in the 1960s it took on a national and international character, with access to the mass media and incorporating a wide mixture of grassroots activist organizations and prestigious professional bodies. Cooper was a South African psychiatrist working in Britain. A trained Marxist revolutionary, he argued that the political context of psychiatry and its patients had to be highlighted and radically challenged, and warned that the fog of individualized therapeutic language could take away people's ability to see and challenge the bigger social picture. He spoke of having a goal of "non-psychiatry" as well as anti-psychiatry. In the 1960s fresh voices mounted a new challenge to the pretensions of psychiatry as a science and the mental health system as a successful humanitarian enterprise.
