Three major psychosocial theories of aging—activity theory, disengagement theory, and continuity theory—are summarized and evaluated.
Similarly one may ask, what is meant by role theory?
Role theory examines how people play out socially defined roles (e.g., mother, sister, wife, manager, teacher) and their ability to adhere to society’s expectations of acceptable and unacceptable forms of behavior for the particular role (DeLamater and Myers, 2011).

- The Free Radical Theory.
- The Membrane Theory of Aging.

Hereof, what are two theories of aging?
Modern biological theories of aging in humans currently fall into two main categories: programmed and damage or error theories.
What are the main theories of aging?
Modern biological theories of aging in humans fall into two main categories: programmed and damage or error theories. The programmed theories imply that aging follows a biological timetable, perhaps a continuation of the one that regulates childhood growth and development.
What causes biological aging?
Factors that influence biological age
Scientists now know that many factors – including physical exercise, sleep , depression, and certain gene mutations – are associated with reduced telomere length, and, by extension, can lead to premature biological aging.
What is the main idea of role theory?
Role theory deals with the organization of social behavior at both the individual and the collective levels. Individual behavior in social contexts is organized and acquires meaning in terms of roles.

What is cellular aging theory?
Cellular theories of aging propose that human aging is the result of cellular aging, whereby an increasing proportion of cells reach senescence, a terminal stage at which cells will cease to divide. This will limit the body’s ability to regenerate and to respond to injury or stress.
What programmed aging?
Programmed aging refers to the idea that senescence in humans and other organisms is purposely caused by evolved biological mechanisms to obtain an evolutionary advantage. … The theories also make predictions regarding the nature of biological aging mechanisms and therefore suggest research directions.
