Child development

1. Piaget's theory

   • Schemas
     • Combination of schemas= operations
     • Existing schema, new situation= assimilation
     • Existing schema won't work, modify to change and deal with it= accomodation
       • Disequilibrium causes this
   • Stages of cognitive development
     • Sensori-motor; 0-2 years
       • Simple reflexes
       • Primary, secondary and tertiary circular reaction
       • Internalization of schemas
       • Object permanence
       • Bower, 1972
         • Object (i.e. teddy bear) exists out of sight (still reaches for it even in dark)
     • Pre-operational period; 2-7
       • Use words and communicate
       • animism
       • Egocentricity- not understanding others view point
         • Piaget 1967 mountain study
         • Hughes 1975, police man, wall and doll, 3-5 years old, 90% successful; children need context/ understanding
       • Conservation- two glasses different sizes, water study
       • Sereation- if A=B and B= C can A=C
       • Class inclusion- count pigs and houses, which is more; <6 cant do it
     • Concrete operations, 7-11
     • Formal operations, 11+; deductive reasoning
