Define habituation and describe how researchers use the habituation-dishabituation technique to examine infant visual perception

What will be an ideal response?

Habituation refers to the tendency for an organism to reduce its responsiveness to a stimulus as a result of repeated exposure. Researchers have used their knowledge of habituation to obtain evidence regarding infants' visual perception abilities. In using the habituation-dishabituation technique, researchers present infants with the same visual stimulus repeatedly until the infants habituate, or show decreased responsiveness, to it. Then, the experimenter presents a new stimulus. If the infant shows "dishabituation," that is, if the infant shows renewed interest and responsiveness to this new stimulus, the infant's behavior is said to indicate that he or she has processed the difference between the first stimulus and the second stimulus. In other words, the infant can visually perceive the differences between the two stimuli.
