21. The author suggests that, by 1950, attempts to cor- relate mental experience with brain processes would probably have been viewed with
(A) indignation (B) impatience
(C) pessimism (D) indifference (E) defiance
22. The author mentions "common currency" in line 26 primarily in order to emphasize the
(A) lack of differentiation among nerve impulses in human beings
(B) similarity of the sensations that all human beings experience
(C) similarities in the views of scientists who have studied the human nervous system
(D) continuous passage of nerve impulses through the nervous system
(E) recurrent questioning by scientists of an accepted explanation about the nervous system
23. The description in lines 32-38 of an experiment in which electric stimuli were applied to different sen- sory fields of the cerebral cortex tends to support the theory that
(A) the simple presence of different cortical areas cannot account for the diversity of mental experience
(B) variation in spatiotemporal patterning of nerve impulses correlates with variation in subjec- tive experience
(C) nerve impulses are essentially homogeneous and are relatively unaffected as they travel through the nervous system
(D) the mental experiences produced by sensory nerve impulses are determined by the corti- cal area activated
(E) variation in neuron types affects the quality of nerve impulses
24. According to the passage, some evidence exists that the area of the cortex activated by a sensory stimu- lus determines which of the following?
I. The nature of the nerve impulse
II. The modality of the sensory experience
III. Qualitative differences within a modality
(A) II only (B) III only (C) I and II only
(D) II and III only (E) I, II and III
25. The passage can most accurately be described as a discussion concerning historical views of the
(A) anatomy of the brain
(B) manner in which nerve impulses are conducted
(C) significance of different cortical areas in mental experience
(D) mechanics of sense perception
(E) physiological correlates of mental experience
26. Which of the following best summarizes the author's opinion of the suggestion that different areas of the brain determine perceptions produced by sensory nerve impulses?
(A) It is a plausible explanation, but it has not been completely proved.
(B) It is the best explanation of brain processes cur- rently available.
(C) It is disproved by the fact that the various areas of the brain are physiologically very similar.
(D) There is some evidence to support it, but it fails to explain the diversity of mental experience.
(E) There is experimental evidence that confirms its correctness.
27. It can be inferred from the passage that which of the following exhibit the LEAST qualitative variation?
(A) Nerve cells (B) Nerve impulses
(C) Cortical areas
(D) Spatial patterns of nerve impulses
(E) Temporal patterns of nerve impulses
