Document Summary
Mini-lecture 6-4: sensation and perception case study - Pattern detection (face recognition as a special case) Visual acuity - the ability to see fine details, and discriminate small differences in items. Davida teller - developer of the teller acuity cards. One side of card has white and black lines, and the other side is gray. Should focus more on the side with the grating. If the baby doesn"t recognize the grating, then they should spend an equal amount of time looking at both sides of the card. If given a chance to look at a face, the babies will look more at a face than the grating, so the peephole is to cover the face while still being able to see the baby"s eyes. Some infants have a side preference, so you test the grating on both sides. See when the babies are no longer able to determine the smallest grading they can discriminate.
