  • what is the life course trajectory of bodily functions?

    - normal development and decline
    - exposure in early life may leave imprints on structures or functions of body systems
    - exposure acting in mid or in later life accelerating age-related decline
  • What are the definitions of age?

    • chronoligical age: measured in units of time
    • biological age: where people stand relative to the years they will live
    • functional age: persons competence in carrying out specific tasks in comparison with pears
    • psychological age: refers to how well a person adapts to changing conditions
    • social age: views held by most members of a society about what the individuals in a particular age group should do and behave
  • What are the ages in the chronological age?

    • young-olds: 65-74
    • old-old: 75-84
    • oldest-old 85+
  • What are the theoretical models of aging?

    • the selective optimization with compensation model of aging
    • the ecological model of aging
  • what is the selective optimization with compensation model of aging?

    individuals engage in adaptions, and rely on reserve capacity that they do not use under normal circumstances

    • Selection
      a strategy of concentrating efforts on domains in which effective functioning is most likely to remain high
    • optimization
      a strategy of focusing on the behaviours that maximize quantity and quality of life
    • compensation
      refers to substituting new strategies when losses occur  
  • What is the ecological model of aging?

    • the interaction between a persons competence and environment results in some level of adaptation (measured in persons well-being)
    • competence
      physical, sensory, cognitive and social capabilities
    • A person with high competence will adapt positively to a wider range of environmental press than a person with low competence
  • What are the theories of biology of aging?

    • primary aging
    • secondary aging
  • What is primary aging? (programmed theories)

    • unevitable biological process 
    • is set in motion early in life
    • is intrinsic
  • what is secondary aging? (stochastic theories)

    • experienced by most but not necessary by all
    • resulting from hostile environmental influences
  • what are the programmed theories?

    • time clock theory
    • immune theory
    • evolutionary theory
