　　“GRE阅读练习：Visual recognition”由出国留学网GRE考试栏目为您整理，希望本文内容对各位童鞋接下来的考试有所帮助，小编祝大家考试顺利!

　　Visual recognition involves storing and retrieving memories. Neural activity, triggered by the eye, forms an image in the brain‘s memory system that constitutes an internal representation of the viewed object. When an object is encountered again, it is matched with its internal representation and thereby recognized. Controversy surrounds the question of whether recognition is a parallel, one-step process or a serial, step-by-step one. Psychologists of the Gestalt school maintain that objects are recognized as wholes in a parallel procedure: the internal representation is matched with the retinal image in a single operation. Other psychologists have proposed that internal representation features are matched serially with an object‘s features. Although some experiments show that, as an object becomes familiar, its internal representation becomes more holistic and the recognition process correspondingly more parallel, the weight of evidence seems to support the serial hypothesis, at least for objects that are not notably simple and familiar.

　　“GRE阅读练习：Internet induced depression”由出国留学网GRE考试栏目为您整理，希望本文内容对各位童鞋接下来的考试有所帮助，小编祝大家考试顺利!

　　A decrease in face-to-face social contact can precipitate depression. Time spent using the Internet cannot be spent in face-to-face social contact, so psychologists have speculated that sharply increasing Internet use can cause depression. Studies of regular Internet users have found a significantly higher incidence of depression among those who had recently doubled the amount of time they spent using the Internet than among those whose use had not increased. Hence, the psychologists’ speculation is correct.

　　1. Which of the following is an assumption on which the argument depends?

　　A. In general, the reason that the people in the studies had doubled their Internet use was not that they had earlier experienced a significant decrease in opportunities for face-to-face social contract.

　　B. A sharp decrease in face-to-face social contact is the only change in daily activity that can lead to an increased incidence of depression.

　　C. Using the Internet presents no opportunities for people to increase the amount of face-to-face social contact they experienced in their daily lives.

　　D. Regular Internet users who are depressed will experience an immediate improvement in mood if they sharply decrease the amount of time they spend on the Internet.

　　E. Before they doubled the time they spent on the Internet, the people who did ...
