Cognitive Development — Flashcards & Quiz

Q1: Describe Piaget’s four stages of cognitive development.

Sensorimotor (0–2 years): learning through senses and motor actions; develops object permanence. Pre-operational (2–7 years): symbolic thinking and language develop; characterised by egocentrism and centration; lacks conservation. Concrete operational (7–11 years): logical thinking about concrete objects; masters conservation, classification and seriation; understands reversibility. Formal operational (11+ years): abstract and hypothetical thinking; deductive reasoning and systematic problem-solving.

Q2: Compare Piaget’s and Vygotsky’s theories of cognitive development.

Piaget: development is driven by biological maturation through universal stages; children construct knowledge independently through active exploration (constructivism). Vygotsky: development is driven by social interaction and cultural context; learning occurs through guided interaction with more knowledgeable others (MKO) within the zone of proximal development (ZPD). Scaffolding (temporary support) bridges the gap between current and potential ability. Piaget emphasised individual discovery; Vygotsky emphasised social collaboration.

Q3: What is object permanence and when does it develop?

Object permanence is the understanding that objects continue to exist even when they cannot be seen, heard or otherwise sensed. According to Piaget, this develops during the sensorimotor stage, typically around 8–12 months. Before developing object permanence, infants behave as though a hidden object ceases to exist (out of sight, out of mind). The A-not-B error (searching for an object where it was previously hidden rather than where it was last seen) is a common early mistake.

Q1: According to Piaget, children in the pre-operational stage can successfully complete conservation tasks.

Answer: FALSE

Children in the pre-operational stage (2–7 years) typically fail conservation tasks because they focus on one dimension (centration) and lack the ability to mentally reverse operations (reversibility). Conservation is typically mastered in the concrete operational stage (7–11 years).

Q2: Vygotsky’s zone of proximal development (ZPD) refers to the gap between what a learner can do alone and what they can do with guidance.

Answer: TRUE

The ZPD is the distance between a learner’s current independent ability and their potential ability with guidance from a more knowledgeable other (MKO). Scaffolding — temporary support that is gradually removed — helps the learner bridge this gap.

Q3: Object permanence typically develops during Piaget’s formal operational stage.

Answer: FALSE

Object permanence develops during Piaget’s sensorimotor stage (0–2 years), typically around 8–12 months. The formal operational stage (11+ years) is characterised by abstract and hypothetical thinking.
