Question

Quizplus · Accepted Answer

Classical conditioning has been demonstrated with infants in the first few days after birth with a limited number of responses and under optimal conditions. Research has shown that infants can develop associations between stimuli and responses as early as a few days after birth. However, the degree to which they can do so is limited, and it often requires optimal conditions such as high-contrast stimuli and repeated pairings.
