Question

major and related theories of cognition ch5:q2 jean piaget theorized that children learn and process new information in three phases. please describe the \assimilation\ of new information. ch5:q3 piaget developed four stages of cognitive development. please list each stage and the age range. ch5:q4 lev vygotsky theorized that children learn through interactions with peers and adults. please describe the concept of \scaffolding.\

Explanation:

• Ch5:Q2: Assimilation in Piaget's theory is when children incorporate new information into existing cognitive schemas without changing the schemas. For example, a child who knows a dog as a four - legged animal may call a new four - legged animal (like a cat) a dog at first as they fit it into their dog - schema.
• Ch5:Q3: The four stages of Piaget's cognitive development are: Sensorimotor stage (birth - 2 years), Pre - operational stage (2 - 7 years), Concrete operational stage (7 - 11 years), and Formal operational stage (11 years - adulthood).
• Ch5:Q4: Scaffolding in Vygotsky's theory is the support provided by more knowledgeable others (peers or adults) to help a child perform tasks that are just beyond their current level of ability. This support is gradually removed as the child gains more competence.

Answer:

• Ch5:Q2: Assimilation is incorporating new information into existing cognitive schemas without altering the schemas.
• Ch5:Q3: Sensorimotor stage (birth - 2 years), Pre - operational stage (2 - 7 years), Concrete operational stage (7 - 11 years), Formal operational stage (11 years - adulthood).
• Ch5:Q4: Support by more knowledgeable others to help a child perform tasks beyond their current ability, which is gradually withdrawn as the child gains competence.
