Document Summary
From biological rhythms (e. g. sleep-wake cycle) to social rhythms. Acquisition of biological regulatory skills interactional synchrony. Development of biological rhythms that help babies deal with the time-based nature of social interaction. Faces, especially the eyes (study tracked the eye movements of infants as young as 1-2 months) Auditory preparedness for social interaction: well-developed before birth. Adults speak in shorter sentences and more slowly. Become attuned to native language by 9 months. Newborns can discriminate among different odors and tastes and prefer those that adults find pleasant. Beyond faces and voices: primed to be a social partner. If too stimulating, infants turn away, cry, or distract themselves. They can alter the course of the interaction with emotional expression. Regional eeg collected in 6 biological offspring of socially phobic parents (m age = 10. 67 years) and 10 children of healthy control parents (m age = 10. 25 years) Cooler colours on eeg reflect less activity (warmer = more)
