(0-2) explores with senses, moves around; object permanance
47

(2-6) use of symbols, ego centrism, no conservation
48
Concrete Operational
(7-12) logical thought, conservation, mathematical operations, empathy
49
Formal Operational
(12+) hypothetical thinking, hypothesis testing
50
Criticisms to Piaget's Stage Theory
stages don't necessarily happen gradually, ignores roles of environment, some adults may never reach formal operational stage
51

Behaviors socially expected of males and females
52
Gender Schemas
Expectations people have of the behaviors of men and women

57
Early Adulthood
(20s-30s) few changes, but ageing begins
58
Mid-adulthood
(40s-50s) visual changes and decline in hearing, Hair grays & strength declines. Increased weight and height reductions
59
Late Adulthood
(60s & on) hearing impairments, osteoporosis, neurogenerative disease
60
Menopause
Decreased levels of estrogen lead to perimenopause in 40s & cessation of ovulation in 50s
61
Andropause

65
Authoritative
Firm limits and flexibility. Children have clear limits and tend to be self-reliant
66
Ageing
Potential for development of dementia related to Alzheimer's, challenges in memory and changes in intelligence
67
Alzheimer's
Brian degeneration. Begins with minor memory impairments, but progresses to serious difficulties in keeping routines to complete loss of memory(dementia)
68
5 Stages of Morality
``` Denial = refuse to accept death is real Anger = @ incapacity to change outcome Bargaining = attempt to make a deal to change outcome Depression = sadness from losses Acceptance = Accepting the inevitable ```
