Development Overarching theme: Nature versus nurture I. Neural development -general structure -synaptic growth/pruning II. Motor Development -reflexes -motor skills: stages III. Perceptual development -terrible initially, but develops quickly IV. Social development, affectionate ties -Schaffer & Callender (1959), Harlow’s attachment study -the importance of play -birth-2 yrs: actions--consequences -3-7, role-playing, social contact -8+: conflict resolution, skill development

Development Intellectual Development Piaget’s Stage theory of cognitive development -concept of “schemata” -assimilation, accommodation, reorganization 1) Sensorimotor stage (0-2 years)
Development Intellectual Development Piaget’s Stage theory of cognitive development 1) Sensorimotor stage (0-2 years) 2) Preoperational stage (2-7 years) -lack of seriation, conservation of number/mass/volume
Development Intellectual Development Piaget’s Stage theory of cognitive development 1) Sensorimotor stage (0-2 years) 2) Preoperational stage (2-7 years) -lack of seriation, conservation of number/mass/volume 3) Concrete Operational stage (7-11 years) -can seriate, classify hierarchically, conserve
Development Intellectual Development Piaget’s Stage theory of cognitive development 1) Sensorimotor stage (0-2 years) 2) Preoperational stage (2-7 years) -lack of seriation, conservation of number/mass/volume 3) Concrete Operational stage (7-11 years) -can seriate, classify hierarchically, conserve -can reason and hypothesize with real-world situations, but not abstract ones (i.e. an experience-based reasoning as opposed to pure reasoning) 4) Formal Operational stage (12+ years)
Criticisms of Piaget 1) Subjectivity of methods, over-interaction between tester and child 2) Stages not clearly delineated (decalage) 3) Tasks set up against the child succeeding -e.g. misleading visual cues in conservation 4) Evidence against some of his findings
