Psych 230 Study Guide for Exam II 1. Perceptual Development Perception is the organization and interpretation of sensed energy into meaningful forms a. Describe the methods used to study perception in infants. What do these methods tell us? Preference Method- two objects are presented simultaneously and we record how long infant attends to each one Habituation Method- a stimulus becomes so familiar or boring that infant stops showing any response to it Evoked Potentials- present with a stimulus and record brain waves These studies tell us that infants can discriminate and show perforation b. What kinds of patterns can newborns see? When can they see patterns like adults? Infants aged 2 months and older can discriminate patterns similar to adults- even highly complex ones. Newborns can see an prefer high contrast to moderately complex patterns, and curvilinear rather than linear patterns c. What preferences for smell and taste do infants have?

Study group was small. g. How does perceptual development change as we get older in all domains? Information processing is less perceptually dominated as we get older. 2.
