Language function and dysfunction among Chinese- and English-speaking polyglots: Cortical stimulation, Wada Testing, and clinical studies 总被引:6,自引:0,他引:6
Language functions in a group of Chinese- and English-speaking polyglots living in a multiracial society have been investigated by several methods: the effects of cortical stimulation on object-naming and reading tasks in patients who required awake craniotomy, lateralization of cerebral dominance for speech by the Wada Test, and the pattern of language loss and recovery following stroke. The data indicate that these polyglots were all left hemisphere dominant for the languages tested: no consistent evidence for increased participation by the right hemisphere for language functions was found. The cortical stimulation experiments provided data most compatible with the "differential localization" model of cerebral localization in bilingualism. The variable which most influenced performance in all of these investigations was which language was used primarily for speaking as well as reading and writing at the time of the study. 相似文献

The Job Attitude Scale was administered to majors and captains and to upper-middle managers and lower-middle managers of industrial organizations. No significant differences in general intrinsic orientation were found between the majors and the upper-middle managers, or between the captains and the lower-middle managers. The majors and the upper-middle managers were significantly more intrinsically oriented than the captains and the lower-middle managers. The results also showed that the military samples were significantly more concerned with advancement, security, status, and family needs-salarywise-than the civilian samples, while the two civilian groups were significantly more concerned with achievement, supervision, and relations with subordinates than the two military groups. The results were discussed in view of job environment and job level. 相似文献

The psychological meaning and predictive value of a person's vocational aspirations were examined by applying Holland's typology to the vocational aspirations of high school juniors (N = 1005), college juniors (N = 692), employed adults (N = 140), and a second sample of college students studied over a one-year interval (N = 624). The aspirational data were obtained from the Daydreams section of the Self-Directed Search (Holland, 1972). Categorical and correlational analyses show that a person's retrospective vocational aspirations have coherence and yield efficient predictions of subsequently expressed choice. In addition, the degree of coherence or similarity among a person's vocational aspirations provides a potentially useful index of a person's decision-making ability. 相似文献

The influence of the presence and novelty of an adult stranger on the reactions of 12-mo-old infants was investigated. Subjects were placed near their mothers in a room containing a new toy and either the same, a different, or no adult stranger for 8 4-min trials. Results indicated that the Same-Adult Group spent more time near the adult, less time near and touching their mothers, and more time near and touching the toys than the Different-Adult Group. These trends emerged as the trials progressed, and evidenced the Same-Adult Group's growing familiarity with the adult. The No-Adult Group spent less time near or touching their mothers and more time near or touching the toys than the Different-Adult Group, but did not differ from the Same-Adult Group on these responses. The findings suggest that fearful or cautious reactions to adult strangers disappear rapidly as the adult becomes familiar and point to the value of studying the process whereby the infant becomes familiar with new people. 相似文献

Preschool children's understanding of temporal relationships was examined in terms of their comprehension of sentences containing clauses linked by before and after. The relative importance of order of mention and main-subordinate relations strategies in children's interpretation of temporal order information was also evaluated.Divergent error patterns emerged on the tasks; omissions prevailed on the two tasks involving response to commands, reversals prevailed on the other. Further examination revealed that omissions reflected ambiguity in the linguistic structure of commands. Thus the effect of main-subordinate relations was confounded with directness of command. On all comprehension tasks, however, performance was superior on sentence forms in which order of mention and order of occurrence correspond. 相似文献

In the first of three studies college, third grade, and kindergarten Ss were able to determine that two stimuli presented 700 msec apart were the same more quickly if they were visually identical than if they shared the same name. If 3000 msec elapsed between stimulus presentations third grade and college Ss responded at the same rate in making both types of matches, whereas kindergarten Ss appeared to continue to respond more quickly in making visual matches. Study II was an unsuccessful attempt to replicate the kindergarten finding. A warning signal, presented 500 msec prior to the second stimulus, reduced RTs at both interstimulus intervals, but no significant differences in making visual and name matches occurred. In Study III first-graders, responding either with or without a warning signal, were found to respond like the older Ss in Study I. The warning signal again reduced RT at both intervals. The results suggest that Ss across a wide age range are able to use the visual properties of a stimulus for only a very brief period as the basis for making matching judgments. 相似文献

A reaction time (RT) paradigm was developed to study retrieval processes in paired associate (PA) recall. Prior to the experimental session, subjects learned lists of PAs (varying in length from three to 24 pairs); during the experimental session, subjects' RT to say the response word from the onset of a visually presented stimulus word was measured. The implications of several classes of retrieval models were discussed in the context of this paradigm. The shape of the RT-list length function, practice, and sequential effects were all of interest in distinguishing among models. Four experiments were reported which were designed to (1) establish the baseline effects in this paradigm, (2) determine which of these effects should be attributed to the retrieval stage of processing, and (3) investigate the effect of semantic memory in this task. Results suggest that simple serial scanning models are inadequate to handle the data from this task. Strength, direct-access, or parallel processing models, on the other hand, seem to capture the qualitative effects present in our experiments. When a strength model was formalized and fit to the data from Experiment I, it was found that a two-trace version gave good quantitative fits while a one-trace version did not, suggesting that both short- and long-term memory independently contribute in this task. 相似文献
