Who? motor skills developed in early childhood are correlated with cognitive skills. e.g., motor music skills and Suzuki study explanations
Piaget
-organized ways of making sense of experiences -change with age (action-based sensorimotor patters. later mote to "thinking before acting" pattern - creative & deliberate) -building schemes
Piaget's Theory: Schemes
T/F. Historically, anesthesia was not used on newborns because they were once thought to not be sensitive to pain or touch. Recently this has found to be incorrect and newborns ARE sensitive to pain and touch
T
adjusting old schemes and creating new ones to better fit environment
accommodation
building schemes through direct interaction with environment
adaptation
infants modulate their movement patterns to fit a new task by exploring and selecting possible configurations. (universal milestones are learned through this)
adaptation
opportunities for interaction offered by objects that fit within our capabilities to perform activities e.g., pot--offer something to cook with
affordances
using current schemes to interpret external world
assimilation
-Use ___________ during equilibrium and disequilibrium prompts______________. -Organization (internal rearranging and linking schemes)
assimilation, accommodation

size constancy
other people (especially older caregivers) contribute to cognitive development
social contexts
when newborns suck an object placed in their mouth. the sucking reflex enable the infant to get nourishment before it has begun to associate a nipple with food; it also serves as a self-soothing or self-regulating mechanism (example of individual differences in reflexive behavior appear soon after birth)
