The present paper is intended to discuss critically the integration model of the functional interhemispheric relation that has become dominant in neuropsychology with the development, in the last two decades, of split-brain studies.While the split-brain research has undoubtedly produced new experimental methodologies, the current theorizing in this area has been contrastingly conservative. The present paper examines some of its basic assumptions, in particular that the corpus callosum is an association pathway devoted to interhemispheric transmission of information, and that the disconnected cerebral hemispheres function in a parallel way. It is shown that these assumptions have only low consistency both with split-brain behavior and with the normal organization of the fore-brain connectivity.In the early seventies, theoretical novelty has emerged from another research field with Kinsbourne's interpretation of laterality effects in normal man. His concept of asymmetrical hemispheric arousal is shown to be supported, with some reservations, by evidence in this field. But this dynamical concept has a more general value and there are signs that current ideas about the functional relation between the cerebral hemispheres are presently deeply transformed. 相似文献

Forty-six subjects were assigned to two groups according to a reaction time technique: one monolingual group of 14 subjects with German as the dominant language and one group of 32 German-Swedish bilingual subjects balanced in skills. The subjects were given short-term memory tasks on numbers presented aurally and a visually presented prose text involving both short-term and long-term memory processes. The results provide evidence that two language systems actively used in daily communication affect both speed and memory span for digits: when compared with monolingual subjects, balanced bilinguals read more slowly and showed a higher error rate in the recall of two-digit numbers. The results support a hypothesis of interdependent bilingual storage. 相似文献

Ninety MBA students were randomly assigned to one of six experimental conditions in a 3(levels of disability) × 2(levels of employment history) design. Levels of disability (Physical, Psychiatric, and No Disability) and levels of employment history (Good and Poor) were manipulated by giving the subjects bogus information on a job application form prior to hearing a taped job interview. Subjects then rated the quality of the interview and stated the probability that they would hire the interviewee. Evaluations of the interview and hiring probabilities were different between the experimental groups. Implications and suggestions for future research are discussed. 相似文献

Two laboratory experiments are reported. Each investigates the bias that social relationships exert on a subject's propensity to recall another's completed and uncompleted tasks. Using closed circuit television, subjects in both experiments observed a bogus other working on a set of puzzles. The person working completed only one-half of the puzzles. In three of the six experimental conditions in both experiments, subjects believed that the remaining puzzles could be completed at a later time. In the first experiment, a subject's relationship to the other was determined by cooperative, competitive, or individualistic economic incentives. In the second, the relationship was determined simply by their similarity or dissimilarity on a bogus personality test. Utilizing a combination of Lewinian assumptions and contemporary theory about memory, we hypothesized that the opportunity to resume work would result in an increased propensity to recall uncompleted tasks in the competitive (or dissimilar) conditions and a decreased propensity to do so in the cooperative (or similar) conditions. Results confirmed this hypothesis. Additional data in both experiments suggest that subjects' relationships with the bogus other altered the accessibility of this information. Theoretical implications of these findings and their relationship to research on prosocial behavior are discussed. 相似文献

An experiment was conducted to test implications of Kelley's cube, self-serving bias, and positivity bias formulations for attributions associated with success and failure on a test of “abstract reasoning.” Subjects either experienced or observed outcomes on three tasks. They then made attributions for only the third outcome, which was either a success or a failure. The first task was of the same type and had the same outcome as the third task, thus providing the information that the outcome being attributed was high in consistency. The second task was of a different type than the first and third tasks, and its outcome either did or did not differ from their outcomes, thus varying information about the distinctiveness of the outcome being attributed. Consensus was manipulated by presenting false norms, ostensibly from a previous experiment. In contrast to previous research, the present study included thorough checks on all of these informational manipulations. Regardless of attributor role (actor or observer), subjects attributed success more to internal than to external factors and attributed failure more to external than to internal factors. These findings indicate a general bias toward positive evaluations. Discussion centers on possible alternative interpretations of these findings, restrictions on their generality, and the limitations that they seem to impose on the applicability of the other two formulations. 相似文献

Sixty-four infants, eight boys and eight girls at each of four ages, months, were observed during a 15-minute free play session. Three types of play (stereotypical, relational, and functional) and the number of appropriate uses for specific realistic toys were recorded. Stereotypical play (87% of total active play at months) gave way to relational (35% at months) and functional play (52% at months) as the dominant activity. Both functional play and the number of different appropriate uses of toys were rare at months, appeared reliably at months and increased lineraly through months. A change in the quality of play from indiscriminate mouthing, waving, banging, and fingering of objects to the matching of appropriate uses for a large array of toys indicates that the child's manipulations become more object specific and functional over this 6-month age span. Among possible explanations for the linear increase in the frequency and diversity of appropriate toy uses is the suggestion that an important cognitive change occurs toward the end of the first year of life. A case study is presented to illustrate the application of the play procedure for both assessment and treatment. 相似文献

To what degree do infants use a predictive strategy when reaching for moving objects? This question was studied longitudinally in five infants from 18 to 36 weeks of age. The aiming of 356 reaches were analyzed by a technique that took into consideration the three-dimensional properties of the reaches. Each reach was divided into ballistic steps and the aiming of each step was calculated and compared with an optimal value. It was found that the infants studied had an ability to reach for fast moving objects in a predictive way. Further, the results show that the predictive ability is remarkably good in the lowest age groups which suggests that it is, at least partly, prewired. What develops seems mainly to be the mobility aspects of reaching which makes for more economical and flexible reaching. Older infants reach successfully for the fast moving object also with a nonpredictive chasing strategy. 相似文献

The present research was an attempt to examine the role of task-specific self-esteem Korman, 1966, Korman, 1976 and locus of control (Rotter, 1966) in the differential prediction of academic performance, program satisfaction, and personal life satisfaction. Based on earlier research and theory in this area, it was predicted that (1) high task-specific self-esteem individuals would perform better, would be more satisfied with their program of studies and their personal lives compared to low task-specific self-esteem individuals, and (2) individuals with an internal locus of control would also perform better, would be more satisfied with their program of studies and their personal lives compared to individuals with an external locus of control. These hypotheses found strong empirical support in the study. The findings are interpreted as being strongly supportive of Korman's theory on the role of task specific esteem and Rotter's theory on the concept of locus of control in the prediction of certain select organizational outcomes. 相似文献

The perception of stress and lateralization of prosody 总被引:1,自引:0,他引:1

Three separate dichotic listening tasks were run to determine ear superiority for stress identification. When subjects were asked to identify stress placement in real word minimal stress pairs (hótdog vs. hot dóg), they demonstrated a right ear superiority. When these tokens were filtered so that phonetic and semantic information was eliminated and only the stress pattern remained, a different group of subjects showed a left ear advantage. Finally, with nonsense word counterparts to word stress pairs (bótgog vs. bot góg) preserving phonetic information but lacking semantic content, no ear asymmetry was found. These results suggest that as the linguistic significance of the stimuli is reduced, thereby lessening the linguistic function of stress, there is a less dominant involvement of the left hemisphere in stress processing. Results are discussed in relation to a theory of a functional integration of prosodic and segmental speech components that is paralleled by a working partnership of left and right hemisphere. 相似文献

The phonemic errors of three Finnish Broca's aphasics were analyzed according to various phonological features, frequency of segments, syllable, word, and stress positions, as well as for the phonotactic structure of the uncanonical products. It was found, e.g., that the distance between the syntagmatic error and its source could not be satisfactorily counted by phonemes, since the syllable had to be taken into account also in pathological Finnish. As regards the paradigmatic dimension of the errors, the number of incorrect features is even here in reverse relation to the frequency of the erroneous phonemes. Moreover, it was found that pure quantity errors and vowel harmony deviations are infrequent in the speech of Finnish Broca's aphasics. 相似文献
