The newborn can see the difference between various shapes andpatterns from birth. He prefers patterns for dull or bright solid colors【S1】______and looks longer at stripes and angles than at circular patterns.Within three weeks, however, his preference shifts dramatic to the【S2】______human face. Why should a baby with so little visual experience attend moreto human face than to any other kind of pattern Some scientists【S3】______think this preference represents a built-in advantage for the humanspecies. The object in prime importance to the physically helpless【S4】______infant is a human being. Babies seem to have a natural tendency tothe human face as potentially awarding. Researchers also point out【S5】______that the newborn wisely relies more on pattern than on outline, size,or color. Pattern remains stable, and outline changes with point of【S6】______view; size, with distance from an object; and brightness and color, with lighting. Mothers have always claimed that they could see theirnewborns looking at them as they held them, despite what they have【S7】______told. The experts who thought that perception had to await physical development and the consequence of action were wrong for several reasons. Earlier research techniques were less sophisticated thanwhat they are today. Physical skills were once used to indicate【S8】______perception of objects—skills like visual tracking and reaching for anobject, both of them the newborn does poorly. Then, too,【S9】______assumptions that the newborn’s eyes and brain was too immature for【S10】______anything as sophisticated as pattern recognition caused opposing data to be thrown away. Since perception of form was widely believed to follow perception of more "basic" qualities such as color and brightness, the possibility of its presence from birth was rejected.【S2】
