Ten Wernicke's and ten Broca's aphasics were compared with normal controls and brain-damaged nonaphasics with respect to the time required for the auditory decoding of object names. This value was obtained by using a subtraction method with two reaction time determinations, one of which included an auditory processing phase while the other did not. The overall mean of approximately 200 msec for Broca's aphasics did not differ significantly from the normal, while the mean of 650 msec for the Wernicke aphasics was much slower. All groups responded more quickly to high-frequency than low-frequency words and all but the Wernicke aphasics improved in the second trial block over their performance in the first trial block. 相似文献

Do I have a special reason to care about my future, as opposed to yours? We reject the common belief that I do. Putting our thesis paradoxically, we say that nothing matters in survival: nothing in our continued existence justifies any special self-concern. Such an “extreme” view is standardly tied to ideas about the metaphysics of persons, but not by us. After rejecting various arguments against our thesis, we conclude that simplicity decides in its favor. Throughout the essay we honor Jim Rachels, whose final days exemplified his own unselfish morality as well as the “neutralist” ideal we espouse. As an appendix, we include the last original work to be published by James Rachels, in which he criticizes Sidgwick’s most famous defense of egoism. 相似文献

It has been suggested that asymmetries in the morphological properties of the face contribute to or produce asymmetries in facial emotional expression. Over 50 years of research on hard tissue, soft tissue, and facial surface asymmetries is reviewed here. Generally, it appears that if consistent asymmetry characterizes facial morphology, it is extremely small in magnitude or characterizes regions yet to be examined. In contrast, marked homology and asymmetry in regional size and area has been noted often. At present, it does not appear that asymmetry in facial morphology is associated with facial expressive asymmetry, with the latter more likely to be an outcome of functional brain asymmetry. 相似文献

Female right-handed subjects were presented with a memory set consisting of five unfamiliar female voices. They were then tested with a recognition procedure in which samples of voice, memory set or novel, 2 or 4 sec in duration, were heard in one ear and a competing noise stimulus was heard in the other ear. There was an overall left-ear advantage in accuracy of recognition. This advantage held particularly for identifications of memory-set voices in the second half of trials. Internal analyses indicated that the left-ear advantage could not be attributed to greater retroactive interference during right-ear presentation. Congruent with studies of recognition of unfamiliar faces, the findings suggested right-hemisphere superiority in the recognition of unfamiliar voices. 相似文献
