Habituation in infants is characterized by which of the following?

Habituation in infants refers to a psychological process where they demonstrate a decreased response to a repeated stimulus. This phenomenon occurs when an infant is exposed to the same stimulus multiple times and gradually becomes less responsive to it. The fundamental principle behind habituation is that as the infant gets familiar with the stimulus, their interest wanes, leading to a reduction in responsiveness.

This process is crucial for infants as it helps them to focus their attention on new and potentially more important stimuli in their environment, allowing them to learn and adapt. Decreased response is an adaptive mechanism that allows infants to filter out stimuli that are no longer new or threatening, thus conserving cognitive resources for novel experiences. Understanding habituation is essential in developmental psychology as it provides insights into sensory processing and learning in early childhood.
