Document Summary
3050 chapter 4: infant perception and cognition basic perceptual abilities of young infants. It was once thought that infants were born deaf and blind. Although far from mature all of the infants senses are functioning: they even prefer some sights smell and sounds ove others. The chemical senses (taste and smell) develop early. Newborn infants are also sensitive to sound pain and touch. Vision develops rapidly over the first year. Babies are non verbal so we cant ask them. Does their attention change when we change the stimulus. Heart rate, eeg, breathing, brain wave activity. Psychophysiological measures look at the nervous system. Preference method: present infant with 2 stimuli and observe whether infant attends to one stimulus more than the other. Present 2 voices recordings does infant turn to left or right speaker. Do they respond differently to the different stimuli. Preferential looking method: visual preference paradigm. Fantz placed babies in a looking chamber and presented them several visual stimuli.
