Question

What is involved in the process of visual recognition? First, like computer data, visual memories of an object must be stored; then, a mechanism must exist for them to be retrieved. But how does this process work? The eye triggers the nerves into action. This neural activity constructs a picture in the brain’s memory system, an internal image of the object observed. When the eye once again confronts that object, the object is compared with its internal image; if the two images match, recognition takes place.

Among psychologists, the question as to whether visual recognition is a parallel, single-step operation or a sequential, step-by-step one is the subject of much debate. Gestalt psychologists contend that objects are perceived as wholes in a parallel operation: the internal image is matched with the retinal impression in one single step. Psychologists of other schools, however, suggest the opposite, maintaining that the individual features of an object are matched serially with the features of its internal image. Some experiments have demonstrated that the more well-known an object is, the more holistic its internal image becomes, and the more parallel the process of recognition tends to be. Nonetheless, the bulk of the evidence appears to uphold the serial hypothesis, at least for simple objects that are relatively unfamiliar to the viewer.    1  
 1. According to the passage, psychologists of the Gestalt school assume which of the following about the process of visual recognition?

Select all that apply.

A. The image an object makes on the retina is exactly the same as its internal image.
B. The mind recognizes a given object as a whole; it has no need to analyze the object’s constituent parts individually.
C. The process of matching an object with its internal image takes place in a single step.

 2. One can infer from the passage that, in visual recognition, the process of matching

A. requires neural inactivity
B. cannot take place if an attribute of a familiar object has been altered in some way
C. cannot occur when the observer looks at an object for the very first time
D. has now been proven to necessitate both serial and parallel processes
E. can only occur when the brain receives a retinal image as a single unit

1. According to the passage, psychologists of the Gestalt school assume which of the following about the process of visual recognition?

You can arrive at the correct answer to this question by elimination. First, quickly scan the passage looking for the key word Gestalt. The sentence mentioning Gestalt psychologists states they maintain that objects are recognized as wholes in a parallel procedure. The sentence immediately preceding defines a parallel procedure as one that takes only one step.

Now examine the statements. Do Gestalt psychologists maintain that an object’s retinal image is exactly the same as its internal image? Statement 
is unsupported by the passage.

Statement B  is supported by the passage: lines 10–11 (Gestalt psychologists contend that objects are perceived as wholes in a parallel operation:)indicate that Gestalt psychologists believe objects are recognized as wholes.

Statement C  is supported by the passage: lines 11–12 indicate that Gestalt psychologists believe matching is a parallel process that occurs in one step. Choices B and C are both correct.

Answer: B,C

2. One can infer from the passage that, in visual recognition, the process of matching

Go through the answer choices, eliminating any choices that obviously contradict what the passage states or implies. Remember that in answering inference questions you must go beyond the obvious, beyond what the authors explicitly state, to look for logical implications of what they say.

Choice A  is incorrect. Nothing in the passage suggests that the matching process requires or demands neural inactivity. Rather, the entire process of visual recognition, including the matching of images, requires neural activity.

Choice D  is incorrect. It is clear from the passage that the matching process is not fully understood; nothing yet has been absolutely proven. The weight of the evidence seems to support the serial hypothesis, but controversy still surrounds the entire question.

Choice E  is incorrect. It can be eliminated because it directly contradicts information in the passage stating that recognition most likely is a serial or step-by-step process rather than a parallel one receiving an image as a single unit.

Choices B  and  C  are left. Which is a possible inference? Choice C seems a possible inference. Although the author never says so, it seems logical that you could not match an object if you had never seen it before. After all, if you had never seen the object before, you would have no prior internal image of it and would have nothing with which to match it. What about

Choice B?  Nothing in the passage mentions altering any attributes or features of a familiar object. Therefore, on the basis of the passage you have no way to deduce whether matching would or would not be possible if such a change took place. There is not enough information in the passage to justify Choice B as an inference.

The correct answer is Choice C.
