Vygotsky's Theory of Cognitive Development

A set of vocabulary flashcards covering the key terms, definitions, and concepts from Lev Vygotsky's theory of cognitive development.

Lev Vygotsky

The psychologist who proposed that social interaction, culture, and language are the primary drivers of cognitive development, and who died of tuberculosis in 1934 at age 37.

Four Elementary Mental Functions

The four innate mental functions identified by Vygotsky—attention, sensation, perception, and memory—which develop into higher mental functions through social and cultural interaction.

Zone of Proximal Development (ZPD)

The range of tasks that a child can perform with guidance or assistance from a mentor, peer, or tool, but cannot yet accomplish independently.

Zone of Actual Development

The inner area representing tasks and skills that a child has already learned and can perform entirely on their own.

Out of Reach Zone

The area representing tasks that are too difficult for a child to learn or perform, even when assistance and guidance are provided.

Scaffolding

Temporary support matched to a learner's current level that assists them in completing a task, which is gradually removed as the learner gains independence.

More Knowledgeable Other (MKO)

Anyone who possesses a higher level of skill or understanding than the learner regarding a specific task, such as a teacher, parent, older sibling, technology, or tool.

Cultural Tools

Language, symbols, technological devices, or social devices (such as an abacus or AI tools) provided by an environment that influence and shape learning and thinking.

Private Speech

External self-directed talk used primarily by young children to plan, guide, and self-regulate their behavior during problem-solving tasks.

Inner Speech

Silent, internalized thought that develops gradually from external speech, allowing spoken language and thought to operate independently once complete.

Dynamic Assessment

An evaluation strategy that focuses on a student's learning potential based on what they can accomplish with a hint or assistance, rather than evaluating static performance alone.

Reciprocal Teaching

An instructional strategy based on Vygotsky's theory that relies on conversational classrooms where knowledge is co-constructed through dialogue.
