Document Summary
Infants can do much more than what they let on: Remember visual stimuli for longer intervals - make ner distinctions among visual stimuli - signalling recognition of familiar objects. Recognition: noticing when a stimulus is identical or similar to one previously experienced. Different from recall: remembering something in the absence of perceptual support. Finding hidden toys and imitating actions of others. Habituations: the predictable loss of interest that develops once a stimulus becomes familiar. Used to explore infant sensory capacities and thinking. Gradual decrease in the strength of a response after repeated presentations of the same stimulus. Heart rate, attention and respiration all decline to show interest. New stimulus causes infant responsiveness recovery. Learning becomes more ef cient with habituation as the infant is able to focus her attention on new stimulus. Study of habituation/recovery sequence = baby looks at new photo/ stimulus longer - early as third trimester of pregnancy.
