Over 30 years ago, in a comprehensive review of geropsychology published in the prestigious Annual Review of Psychology, Botwinick (1970) identified several core areas within the discipline. These were (1) cognition, (2) perception and psychophysiology, (3) personality and social behaviour, (4) psychological factors that play a role in survival, and (5) analogue studies (e.g., research involving the study of animals) investigating behavioural factors in aging. Additional relevant areas are clinical geropsychology, including clinical geriatric neuropsychology, the broader area of geriatric-health psychology, and others. These areas are representative of the diversity within the discipline of psychology and have seen major developments over the last three decades.
