Study Notes
Biological Theories of Aging
- Biological theories explain physical aging through internal and external factors.
- Intrinsic theories suggest aging is predetermined by genetic factors and cellular lifespan.
- Extrinsic theories suggest environmental factors like pathogens contribute to aging.
- Hayflick Limit Theory indicates the human cell can only divide a certain number of times (around 50) before they stop dividing and die.
- Free-radical Theory highlights the role of free radicals — unstable molecules with an extra charge that damage cells and tissues.
- Error Catastrophe Theory suggests that aging is caused by the accumulation of errors in cellular molecules, leading to dysfunctional cells.
- Somatic Mutation Theory emphasizes the role of DNA mutations caused by exposure to toxins and radiation in aging.
Psychological Theories of Aging
- These theories focus on the interplay between social and psychological factors in aging.
- Disengagement Theory emphasizes the gradual withdrawal from social roles and relationships with aging.
- Personality Theory suggests that personality characteristics in old age are often linked to early life traits.
- Developmental Task Theory argues that successful aging involves accomplishing specific tasks and challenges at different life stages.
- Activity Theory proposes that active engagement in society and activities is crucial for happiness and well-being in old age.
- Continuity Theory suggests that individuals tend to maintain their established behavioral patterns and coping mechanisms as they age.
- Exchange Theory suggests that relationships continue as long as there is mutual benefit but end if there is no value exchange.
Other Theories
- Programmed Cellular Aging Theory suggests a disruption in the process of turning DNA into functional proteins with aging.
- Glycation Theory proposes that the non-enzymatic binding of glucose to proteins can impair cell function and contribute to aging.
- DNA Damage Theories suggest aging is driven by accumulated damage to DNA, leading to cell death.
- Autoimmune Theory suggests that aging causes immune system dysfunction, resulting in the immune system attacking the body's cells.
- Error & Fidelity Theory emphasizes the gradual decline in protein synthesis fidelity, leading to errors in RNA and DNA and impaired cell function.
- Psychosocial Theories of Aging explain cognitive changes related to aging, such as memory and problem-solving skills.
- Jung's Theory proposes a stage of self-reflection in midlife that allows individuals to re-evaluate life choices and decisions.
