Document Summary

Sensation: detection and discrimination of sensory information: perception- interpretation of sensation, attention: selectivity of perception. Key developmental issues for sensation and perception: nature vs. nurture, normative vs. ideographic. Nature: emphasizes the role of biology on sensory experience and interpretation, e. g. Specific neurons in occipital cortex linked with certain type of visual stimulus (vertical edge vs. Horizontal edge: e. g (cid:448)er(cid:455) (cid:455)ou(cid:374)g i(cid:374)fa(cid:374)t"s a(cid:271)ilit(cid:455) to re(cid:272)og(cid:374)ize sou(cid:374)ds (phonemes) from a vast number of different languages. Emphasizes role of experience and formation of associations in learning to interpret sensory information: e. g. Repeated exposure to faces teaches infant to associate nose, eyes, and, mouth as parts of face: e. g. Experience teaches that hearing a voice links better to a face than the sound of a horn does. Some combination of nature and nurture is likely the best explanation for development: with experience, infants and young children become better at detecting and interpreting sensory information --> better at accurately perceiving their environments, e. g.
