Human Growth and Development

Piaget’s Theory
- Sensorimotor Stage
  - Simple reflexes
  - First habits & primary circular reactions
  - Secondary circular reactions
  - Coordination of secondary circular reactions
  - Tertiary circular reactions
  - Internalization of schemes
- Understanding Reality
  - Object permanence
  - Look longer at things that "aren’t right"
Learning and Remembering
- Conditioning
  - Classical
  - Operant
- Habituation/Dishabituation
- Imitation
  - deferred imitation
- All require memory...
  - ... but not necessarily explicit memory
  - implicit memory
- Infantile Amnesia
  - events occur before development of explicit memory
  - brain isn’t mature enough to store it yet!
  - link w/ object permanence
  - more detail w/ development of language
Intelligence
- Developmental Quotient
  - separate normal from delayed babies
    - motor & language development
    - adaptive behavior
    - personal-social behavior
  - not a measure of intelligence, per se
- Bayley Scales of Infant Development
  - use current assessment to predict later development
  - tasks:
    - sorting pegs by color
    - building tower w/ blocks
    - scribbling vs. strokes w/ crayon
    - discriminate between objects
  - range of difficulty, alternate to maintain interest
  - low correlations w/ IQ later on
  - specific activities have a decent prediction
Language Development
- What is language?
- What do babies use it for?
- What is phonology?
