Labeling Psychological Disorders z“Once we label a person, we view that person differently.” (Farina, 1982) zLabels create preconceptions that can bias our perceptions and our interpretations. zThe power of labels to stigmatize people in other’s eyes was illustrated when a female associate of psychologist Stuart Page called 180 people in Toronto who were advertising a furnished room for rent….

10. Labeling Disorders… (p.536) zWhen she merely asked if the room was still available, the answer was nearly always yes. When she said she was about to be released from a mental hospital, the answer three times out of four was no. zIf people form their impressions of psychological disorders from popular media and note hard facts, then it is hardly surprising that stereotypes, judgments, and bias lingers. z Do you think there are still stigmas attached to people with psychological disorders?
