Most episodes of absent-mindedness—forgetting where you left something or wondering why you just entered a room—are caused by a simple lack of attention, says Schacter. "You"re supposed to remember something, but you haven"t encoded it deeply."Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don"t pay attention to what you did because you"re involved in a conversation, you"ll probably forget that the phone is in the jacket now hanging in your wardrobe. "Your memory itself isn"t failing you," says Schacter. "Rather, you didn"t give your memory system the information it needed."Lack of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to drop a letter in the mailbox." Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that.Visual cues can help prevent absent-mindedness, says Schacter. "But be sure the cue is clear and available," he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table—don"t leave it in the medicine chest and write yourself a note that you keep in a pocket.Another common episode of absent-mindedness: walking into a room and wondering why you"re there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, and you"ll likely remember. What do we learn from the last paragraph

The newborn can see the difference between various shapes and patterns from birth. He prefers patterns to dull or bright solid colors and looks longer at stripes and angles than at circular patterns. Within three weeks, however, his preference shifts dramatically to the human face.Why should a baby with so little visual experience attend more to a human face than to any other kind of pattern" Some scientists think this preference represents a built in advantage for the human species. The object of prime importance to the physically helpless infant is a human being. Babies seem to have a natural tendency to the human face as potentially rewarding. Researchers also point out that the newborn wisely relies more on pattern than on outline, size, or color. Pattern remains stable, while outline changes with point of view; size, with distance from an object; and brightness and color, with lighting.Mothers have always claimed that they could see their newborns looking at them as they held them, despite what they have been told. The experts who thought that perception (知觉) had to await physical development and the consequence of action were wrong for several reasons. Earlier research techniques were less sophisticated than they are today. Physical skills were once used to indicate perception of objects-skills like visual tracking and reaching for an object, both of which the newborn does poorly. Then, too, assumptions that the newborn"s eye and brain were too immature for 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. Why were mothers" observations thrown away
