How does Vygotsky's cognitive development model differ from Piaget's?

Answer 1

Piaget's Theory of Cognitive Development Piaget portrayed children as active and motivated learners who, through numerous interactions with their physical and social environments, construct an increasingly complex understanding of the world around them. He proposed that cognitive development proceeds through four stages: (1) the sensorimotor stage (when cognitive functioning is based primarily on behaviors and perceptions); (2) the preoperational stage (when symbolic thought and language become prevalent, but reasoning is "illogical" by adult standards); (3) the concrete operations stage (when logical reasoning capabilities emerge but are limited to concrete objects and events); and (4) the formal operations stage (when thinking about abstract, hypothetical, and contrary-to-fact ideas becomes possible). Developmental researchers have found that Piaget probably underestimated the capabilities of infants, preschoolers, and elementary schoolchildren, and overestimated the capabilities of adolescents. Researchers have found, too, that children's reasoning on particular tasks depends somewhat on their prior knowledge, experience, and formal schooling relative to those tasks. Contemporary developmentalists doubt that cognitive development can really be characterized as a series of general stages that pervade children's thinking in diverse content domains. A few theorists, known as neo-Piagetians, propose that children acquire more specific systems of concepts and thinking skills relevant to particular domains and that these systems may change in a stagelike manner. Many others instead suggest that children exhibit more gradual trends in a variety of abilities. However, virtually all contemporary theorists acknowledge the value of Piaget's research methods and his views about motivation, the construction of knowledge, and the appearance of qualitative changes in cognitive development.

Vygotsky's Theory of Cognitive Development Vygotsky proposed that adults promote children's cognitive development both by passing along the meanings that their culture assigns to objects and events and by assisting children with challenging tasks. Social activities are often precursors to, and form the basis for, complex mental processes: Children initially use new skills in the course of interacting with adults or peers and slowly internalize these skills for their own, independent use. Often, children first experiment with adult tasks and ways of thinking within the context of their early play activities. Contemporary theorists have extended Vygotsky's theory in several directions. For instance, some suggest that adults can help children benefit from their experiences through joint construction of meanings, guided participation, and cognitive apprenticeships. Others recommend that adults engage children and adolescents in authentic, adultlike tasks, initially providing enough scaffolding that youngsters can accomplish those tasks successfully and gradually withdrawing it as proficiency increases. And most developmentalists believe that children's play activities prepare them for adult life by allowing them to practice a variety of adultlike behaviors and to develop skills in planning, cooperation, problem solving, and self-restraint.

Comparing Piagetian and Vygotskian PerspectivesChallenge, readiness, and social interaction are central to the theories of both Piaget and Vygotsky. However, the two perspectives differ on the role of language in cognitive development, the relative value of free exploration versus more structured and guided activities, the relative importance of interactions with peers versus adults, and the influence of culture.
