PSY311H5 Chapter Notes - Chapter 3: Williams Syndrome, Encase, Genetic Variability
Document Summary
A baby"s behaviour follows biological rhythms, which they soon learn to control and regulate. Babies who acquire biological regulatory skills over the first 3 months of life are able to interact with their mothers in synchronous way. When infants are born 6-10 weeks prematurely, biological rhythms, such as the sleep-wake cycle, have not fully developed. They stare longest at objects that have larger visible elements, movements, clear contours, and a lot of contrast (elements that exist on the human face hairlines, chins, dark lips, light skin). By 3 months, infants can identify a face as a unique whole. They look longer and show more brain activity in response to faces than objects and in response to their mother"s face rather than a stranger"s. A baby"s auditory system is well developed even before birth. Babies can even remember a story they have heard before they were born.
