Document Summary

Chapter 6: early cognitive foundations: sensation, perception and learning. Enrichment theory (piaget): cognitive schemes are needed to make sense of sensory info. Differentiation theory (gibson): sensory info can be interpreted on its own, children learn to detect distinctive features. Preference method: two stimuli presented simultaneously, infants attention to each measured. Habituation method: stimulus presented repeatedly until infants response habituates, discrimination ability is tested by presented second stimulus and observing response. Evoked potentials: recording of brain electrical activity, observe changes in activity for different stimuli, changes indicate ability to discriminate. High amplitude sucking: pacifier sucking controls stimulus presentation. Hearing: newborns can know moms voice, early phoneme discrimination, quickly learns to recognize words, more developed than visual ability at birth. Taste and smell: born with taste preferences, react to noxious odors, know moms scent. Touch, temp, pain: therapeutic massage, sensitive to food- room temp, sensitive to pain from circumcision.
