PSYC 101 Lecture Notes - Lecture 6: Face Perception, Facial Recognition System, Speech Perception
Document Summary
Origins of social knowledge: how do we determine who people are, who has a mind, or potential social partners, child must be able to identify faces to identify social beings. Infants recognize/prefer mother"s face after 12 hours of exposure: telling apart other faces, experiment: show infants the face of one individual human until habituated. Then show a novel face next to the original face. At 9 months, they look longer at the novel face, showing that they know the faces are different: experiment: show infants the face of one monkey until habituated. Then show a novel face next to the original monkey face. At 9 months, cannot tell them apart, either because infants learn to distinguish human faces over the 1st 9 months of life or infants start out distinguishing both monkeys and humans and learn not to distinguish monkeys over time. Test 6 months with the same experiment, and found that they can tell apart people and monkeys.
