PS102 Lecture Notes - Lecture 13: Object Permanence, The Big Questions, Moral Development
Document Summary
Developmental psychology looks at changes in biological, physical, psychosocial and behavioural processes as we age. Critical and sensitive periods: critical period age where experiences must occur, sensitive period optimal age range. Stability vs change: do things remain constant. No change remains constant (flat line) Continuous change gradual changes (slow gentle curve) Inverted u-shape emerges early; peaks; diminishes with age (upside u shape) (physical ability is a good example) U-shape function emerges early; disappears-re-emerges later in life (u shaped) (ability to use past tense in english) Research designs: longitudinal test the same cohort at different times. Same people reduces variability across samples. Are changes generalizable to all people or just this group: cross-sectional compare different ages at same time. Different experiences, cultural changes, environmental changes (e. g. wireless technology is now prevelant: sequential test cohorts as they age (shorter period of time) Pros and cons of both cross-sectional and longitudinal. What you and what we see: genetic blueprint and genetic expression.
