Positive Punishment
Reinforcers that satisfy a biological need are called
Primary reinforcers -They are inate
Erikson
Proposed human development is marked by 8 psychological stages from infancy to old age Suggested each age is marked by a developmental task or an emotional crisis that must be resolved Unsuccessful resolution results in difficulty in next stage

Critical periods suggest that
there are at least some definite periods or "stages" in development.
Trust vs. Mistrust
(infant)
Gender
- Dimension of masculinity and femininity based on social, cultural, and psychological characteristics
Genes are found in
