Concept
The disengagement theory of ageing states that "aging is an inevitable, mutual withdrawal or disengagement, resulting in decreased interaction between the aging person and others in the social system he belongs to". The theory claims that it is natural and acceptable for older adults to withdraw from society. There are multiple variations on disengagement theory, such as moral disengagement. Disengagement theory was formulated by Cumming and Henry in 1961 in the book Growing Old and was the first theory of aging that social scientists developed. Thus, the theory has historical significance in gerontology. Since then, it has faced strong criticism since the theory was proposed as innate, universal, and unidirectional. The disengagement theory is one of three major psychosocial theories which describe how people develop in old age. The other two major psychosocial theories are the activity theory and the continuity theory, and the disengagement theory comes to odds with both. Cumming and Henry provided the following nine postulates for the "process of disengagement": Postulate 1: Everyone expects death, and one's abilities will likely deteriorate over time. As a result, every person will lose ties to others in his or her society. Postulate 2: Because individual interactions between people strengthen norms, an individual who has fewer varieties of interactions has greater freedom from the norms imposed by interaction. Consequently, this form of disengagement becomes a circular or self-perpetuating process. Postulate 3: Because men have a centrally instrumental role in America, and women a socioemotional one, disengagement differs between men and women. Postulate 4: The individual's life is punctuated by ego changes. For example, aging, a form of ego change, causes knowledge and skill to deteriorate. However, success in an industrialized society demands certain knowledge and skill. To satisfy these demands, age-grading ensures that the young possess sufficient knowledge and skill to assume authority and the old retire before they lose their skills.
