Document Summary
How do nature and nurture interact: critical and sensitive periods. Critical period; an age rand in which certain experiences must occur for development to proceed normally or along a certain path. Sensitive period; an optimal age range for certain experiences, but if those experiences occur at another time, normal development will still be possible (but not according the social norm timeline: continuity vs. discontinuity. Is development continuous and gradual, or is it continuous and gradual, or discontinuous, progressing through qualitatively distinct stages: stability vs. change. No change an ability present at or before birth that remains relatively constant across the lifespan (e. g. , the ability to discriminate high- from low- pitched sounds, or to see objects as distinct from their background: figure-ground perception). Continuous change (continuity) an ability not present, or very immature, at birth that develops gradually over months or years and then remains constant over age (e. g. , certain types of intelligence).
