Document Summary
Chapter 3: biological foundations: genes, temperament, and more. One way in which babies are biologically prepared for social interaction is that their behaviour follows biological rhythms which they soon learn to control and regulate. Babies and mothers interact in synchrony, we mean that the moth and infant show a predictable degree of responsiveness to each other"s signals during a brief interaction. A second way in which infants are biologically prepared for social interaction is that they are attracted to visual social stimuli. They stare longest at objects that have large visible elements, movement, clear contours, and a lot of contrast faces are appealing because they have boundaries, such as hairlines and chins. Over the first year of life, infants become increasingly skilled and speedy at processing human faces. Babies auditory system is well developed even before birth. Babies especially like a voice that is high in pitch with exaggerated pitch contours.
