2.7 Influences on Cognitive Development

Piaget's Stages Shape Cognitive Growth

Jean Piaget proposed that children move through four stages: sensorimotor, preoperational, concrete operational, and formal operational. Development happens through assimilation (fitting new info into existing schemas) and accommodation (changing schemas to fit new info). Children actively construct understanding rather than passively absorbing it.

Vygotsky's Social Learning View

Lev Vygotsky emphasized that cognitive development is driven by social and cultural interaction. The zone of proximal development (ZPD) is the gap between what a learner can do alone versus with guidance. Scaffolding provides temporary support from a more skilled person to help a child master new skills.

Other Influences on Cognition

Cognitive development is also shaped by biological maturation, nature vs. nurture, and environmental factors like parenting style, education, and culture. Reflexes and inborn temperament interact with experience; enriched environments and social interaction can accelerate reasoning and problem-solving skills over the lifespan.

Key terms

Assimilation

Fitting new information into an existing schema without changing it.

Accommodation

Changing an existing schema to incorporate new information that doesn't fit.

Zone of Proximal Development (ZPD)

The gap between what a learner can do alone and what they can do with guidance (Vygotsky).

Scaffolding

Temporary support from a skilled person that helps a learner accomplish a task, gradually withdrawn as skill grows.
