Activity theory reflects the functionalist perspective that the equilibrium that an individual develops in middle age should be maintained in later years.
The theory predicts that older adults that face role loss will substitute former roles with other alternatives.
For example, if they aren’t able to get around as easy as before to socialize then they might disengage from society.
Disengagement theory The theory was formulated by Cumming and Henry in 1961 in the book Growing Old, and it was the first theory of aging that social scientists developed.
An ageing person’s joints can become stiffer which also may make their movement more painful as the cartilage on the end of their bones becomes thinner and the ligaments also start to become looser. Senses: A person’s sense of balance can become impaired and their ability to taste and smell can deteriorate as they age.
Also, other deteriorations can be vision and hearing.Continuity theory This theory of normal aging states that older adults will usually maintain the same activities, behaviors, personalities, and relationships as they did in their earlier years of life.According to this theory, older adults try to maintain this continuity of lifestyle by adapting strategies that are connected to their past experiences.This theory assumes a positive relationship between activity and life satisfaction.One theorist suggests that activity enables older adults to be able to adjust to retirement.However, Feminist theories attack the continuity theory for defining normal aging around a male model.One weakness of the theory is that it fails to demonstrate how social institutions impact the individuals and the way they age.Physical changes of Ageing Skins, bones, joints & muscles: When a person ages, their skins become thinner, less elastic and an obvious sign; they wrinkle.Also, their bones become less dense which means they are more likely to fracture.Hearing deterioration results in the failure to hear high-pitched sounds.Organs: During the ageing process, it isn’t only the skins, bones, joints, muscles and senses that are affected, the organs are affected too.
