PSYC 101 Lecture Notes - Lecture 7: Habituation, Approximate Number System, Visual Acuity
Document Summary
Review from last class: looked at object perception, piaget"s work, and object permanence. Piaget was a pioneer in infant object perception research: he focused a lot on reaching, other new methods of research have led to different conclusions and insights. Action-focused research implies that infants are not sensitive to what is going on around them, but looking and sucking experiments show us that something is going on in infants" heads (don"t know exactly what though) Analogies- what other cases resemble object perception evidence (an issue of competence vs expression): stepping reflex and visual cliff. Michotte"s illusion: objects exist insofar as we have direct evidence for its existence. Rod experiments: no difference in looking time in the first (stationary) experiment, common motion is an important cue for object determination in infants. Things that move in same direction are likely the same object.
