PSYC 420 Lecture Notes - Lecture 23: Agreeableness, Autobiographical Memory, Neurofibrillary Tangle
Document Summary
Functional age: actual competence & performance, may not match chronological age. Average life expectancy: age to which a person born in a certain year is expected to live. Affected by gender (women live 2-7 years longer than men do) Affected by nationality (developing nations are more likely to suffer from poverty and disease so lower life expectancy) Affected by ses (higher ses = higher life expectancy due to less stress & better access to health care) Affected by heredity (twins normally die around the same time, longevity runs in fams) Is there a limit we can"t live past or will we keep living longer and longer. Aging and the nervous system: loss of brain weight accelerates in the 60s, neuron loss esp in the prefrontal cortex and corpus callosum, ans less efficient (probs regulating body temp), brain can overcome some decline. Cardiovascular/respiratory systems: heart muscle becomes more rigid, heartbeat less forceful, slower aka less oxygen to tissues.
