Definitions:

Habituation Paradigm

A research technique that takes advantage of a baby’s tendency to orient to new stimulation and to habituate to repeated or old stimulation. Once an infant habituates to one stimulus a new stimulus can be presented. The baby’s reorienting to the new stimulus (or failure to do so) reveals whether or not she perceives or notices the differences between the stimuli.

Sensorimotor Period

A stage in Piaget’s theory of cognitive development, from birth to about 2 years of age, where infants learn about the world through their sensory and motor interactions.

Zone Of Proximal Development

A concept in education and psychology referring to the difference between what a learner can do without help and what they can achieve with guidance and encouragement from a skilled partner.
