Piagets Cognitive-Developmental Theory
- Sensorimotor stage
- Key concepts
- Schemes: action-based versus mental
The Sensorimotor Stage: Answer the following while viewing the video,
"Infancy: Beginnings in Cognition."
- What are circular reactions?
- Identify the key characteristics of each of the following substages:
Substage 1: Reflexive Schemes
Substage 2: Repetitive actions/Primary Circular reactions
Substage 3: Actions with people & objects/Secondary Circular
Substage 4: Goal-directed Actions/Coordination of Secondary Circular
Substage 5: Experimentation/Tertiary Circular Reactions
Substage 6: Mental/Symbolic Representation
Recent Research on Sensorimotor Development
- Age of acquisition: underestimated
- E.g., object permanence
- Mental representation
- Problem solving
Evaluation of Sensorimotor stage
- Behaviorist Perspective
- Skinner: operant conditioning
- Nativist Perspective
- Chomsky: Language acquisition device
- Interactionist Perspective
Stages of Language Development
- Cooing & babbling
- Becoming a communicator
- First words
- Two-word utterance phase
- Telegraphic speech
Individual & Cultural Differences
- Referential versus expressive style
Supporting Language Development
- Structure of the system
- Sensory register
- Working/short-term memory
- Long-term memory
- Infant capacities
- Perceptual versus conceptual
- Evaluation of information-processing
The social context of early cognitive Development
Evaluating individual differences in early development
- Intelligence tests
- Early environment
- Early intervention for at-risk infants/toddlers
- Explain Piagets view of what changes with development and how
cognitive change takes place.
- Name Piagets 6 sensorimotor substages, and describe the major
cognitive achievements in each.
- Discuss recent research on sensorimotor development and its implications
for the accuracy of Piagets sensorimotor stage.
- Describe the structure of the information-processing system: the
development of attention, memory, and categorization during infancy and toddlerhood; and
the contributions and limitations of this approach to our understanding of cognitive
- Explain how Vygotskys concept of the zone of proximal development
expands our understanding of early cognitive development.
- Describe the mental testing approach, the meaning of intelligence scores,
and the extent to which infant tests predict later performance.
- Discuss environmental influences on early mental development, including
home, child care, and early intervention for at-risk infants and toddlers.
- Describe 3 major theories of language development, indicating the
emphasis each places on biological and environmental influences.
- Describe how infants prepare for language, and explain how adults support
their emerging capacities (be familiar with questions related to video, "Language
- Describe toddlers first words and 2-word combinations, and explain
why language comprehension develops ahead of production.
- Describe individual differences in early language development and factors
that influence these differences.
- Explain how child-directed speech, conversation, and reading to young
children support early language development.
