Substantial differences exist across ethnic groups and sexes in generational changes in status among groups residing in Hawaii. Despite these generational differences across groups, age differences in personality are remarkably consistent across sexes and racial/ethnic groups, and the few Sex x Age, Ethnicity x Age or Sex x Ethnicity x Age interactions account for little variance in scores. It is concluded that age/generational differences in personality factor scores in these populations result from age and not, to any major degree, from cohort effects. 相似文献

Are variations among right-handed individuals in perceptual asymmetries caused by characteristic arousal differences between hemispheres? 总被引:2,自引:0,他引:2
J Levy W Heller M T Banich L A Burton 《Journal of experimental psychology. Human perception and performance》1983,9(3):329-359
We propose that much of the variance among right-handed subjects in perceptual asymmetries on standard behavioral measures of laterality arises from individual differences in characteristic patterns of asymmetric hemispheric arousal. Dextrals with large right-visual-field (RVF) advantages on a tachistoscopic syllable-identification task (assumed to reflect characteristically higher left-hemisphere than right-hemisphere arousal) outperformed those having weak or no visual-field asymmetries (assumed to reflect characteristically higher right-hemisphere than left-hemisphere arousal). The two groups were equal, however, in asymmetries of error patterns that are thought to indicate linguistic or nonlinguistic encoding strategies. For both groups, relations between visual fields in the ability to discriminate the accuracy of performance followed the pattern of syllable identification itself, suggesting that linguistic and metalinguistic processes are based on the same laterally specialized functions. Subjects with strong RVF advantages had a pessimistic bias for rating performance, and those with weak or no asymmetries had an optimistic bias, particularly for the left visual field (LVF). This is concordant with evidence that the arousal level of the right hemisphere is closely related to affective mood. Finally, consistent with the arousal model, leftward asymmetries on a free-vision face-processing task became larger as RVF advantages on the syllable task diminished and as optimistic biases for the LVF, relative to the RVF, increased. 相似文献

The members of the Committee on Scientific Activities of the American Psychoanalytic Association are concerned about the paucity of clinical data in psychoanalytic reports and by the quality of what does exist. We have proposed a few standards for clinical reports that we believe will be reliable and clear and will have enduring usefulness. We recognize the need for maintaining confidentiality and, at times, for disguise; we also recognize the need to balance these requirements against the dangers of misleading the reader (or listener). These conflicting requirements have resulted in our concentrating on some general principles for clinical reporting. We have appended a tentative form, and examples, to be considered for that purpose. 相似文献

An adolescent female with multiple handicaps and a long history of severely disruptive behavior participated in a functional assessment linked directly to specific revisions in her school curriculum. During Phase 1, reversal designs were used to test hypotheses pertaining to antecedent and auricular influences on problem behavior. During Phase 2, a multiple baseline across afternoon and morning time periods demonstrated that the auricular revisions were effective in eliminating severely disruptive behavior and increasing on-task responding. Data also showed that inappropriate “psychotic” speech was reduced and appropriate social interactions were increased. Follow-up results showed that the changes were maintained throughout the school year. Questionnaire data provided social validation of the procedures and outcomes. The findings are discussed in relation to their implications for functional assessment, individualized curricula, and positive programming for students with disabilities and serious behavior problems. 相似文献

A review of research on the use of the Rorschach in the assessment of cerebral dysfunction indicated that the Rorschachs of patients with cerebral dysfunction do not manifest any characteristic response in terms of percentages, ratios, or any unique response to any one of the stimulus determinants of the blots (color, shading, the stimulus for movement). The patient with cerebral dysfunction does manifest a unique style of thinking; responses tend to be concrete, perseverative, and stereotypic. This finding is similar to that found with schizophrenics where research, summarized by Frank in 1990, also indicated no uniquely 'objective' response style but reflected a unique cognitive style. These two reviews taken together suggest that the better way to use Rorschach data in clinical work is as an opportunity to assess patients' thinking as opposed to the Rorschach being used as a psychometric device, yielding 'numbers.' 相似文献

Previous research (Hall, Scholnick, & Hughes, 1987) suggested that cognitive word meanings denote six increasingly abstract and complex cognitive processes. In this paper, we further investigated two interrelated aspects of this framework. A set of 36 conversations with children aged 4:5 to 5 provided the data. In Study 1, issues related to the optimal ordering of levels were examined by comparing the original sequence with a restructured model. In Study 2, the hypothesis that, in addition toknow, other polysemous cognitive internal state words would be hierarchically organized was tested. The findings lent support to the restructured model, but rejected the hypothesis that polysemous words within the domain were characterized by equivalent,hhierarchically organized levels. We conclude by proposing that cognitive internal state words were related by complementarity of levels rather than equivalence.The research on which this paper is based was supported by a grant from the Carnegie Corporation of New York to William S.

Tested a preventive intervention in which peer telephone dyads were developed for low-income, community-living, elderly women with low perceived social support. After an initial assessment, respondents were randomly assigned to either an assessment-only control or received 10 weeks of friendly staff telephone contact. After a second assessment, participants receiving the staff contact were randomly assigned to continue that contact or were paired in dyads to continue phone contact with one another. Dependent variables were measures of perceived social support, morale, depression, and loneliness. All groups, particularly the staff contact group, showed some improvement in mental health scores over time, but there were no significant differences between intervention groups, or between intervention and assessment-only control groups. The results suggest that participation in the study and in personal assessment interviews at home were probably morale enhancing, and that additional telephone contact did not significantly add to that effect. Evidence also indicates that, in this sample, low perceived family support was significantly related to poor mental health, so it is possible that a program designed to increase friend support may have been the wrong intervention. 相似文献

Consistency between teachers' and parents' ratings of 229 children's prosocial and problem behaviors was investigated from kindergarten through grade two. Intrarater stability was also analyzed. Results indicated moderate but decreasing interrater agreement from kindergarten to grade two for boys on externalizing behaviors. Interrater agreement for the same behavior dimension for girls was moderate and stable, whereas it was low on internalizing behavior problems and prosocial behaviors, for both genders throughout the 3-year period. Moreover, difference between teachers' and parents' ratings of externalizing behaviors increased from kindergarten to grade two. Decreasing level of agreement through time appeared to be related to a reduction of teacher-rated externalizing behaviors not paralleled by a reduction in parent ratings. Analyses were also performed at the item level of the externalization scale to identify which specific behaviors were responsible for the increasing divergence in interrater agreement from kindergarten through grade two. Alternative interpretations were considered in order to account for present and past results. Implications for screening and assessment purposes were discussed.This research was supported by grants from the Social Sciences and Humanities Research Council of Canada and from Québec's Health Research Fund (FRSQ). We wish to thank the authorities and directors of the schools from the Val d'Or School Board as well as the kindergarten, first and second grade teachers, children, and parents for their collaboration.

Functionalism and type-type identity theories 总被引:1,自引:0,他引:1
Conclusion Token-token identity theorists do not and need not deny that it may frequently be the same (kind of) brain state which on different occasions fills the functional rôle definitive of a given mental state. That is not at issue. What is at issue is whether functionally-oriented identity theorists should make two claims or three claims.The two claims they customarily make are, first, that each instance of a mental state is an instance of a brain state, and, secondly, that being in a mental state is having in one a state filling the relevant functional rôle. But to be in a mental state is to have that state in one. To be in pain is to have pain, to desire water is to have desire for water, and so on; just as to be poisoned is to have poison in you. (It is to have what is poison for you at the time, of course; and likewise for pain, desire and so on.)Our paper has been about a third sort of claim — relating particularly not to being in a mental state, nor to instances of that state, but to the mental state itself. We have argued that functionally-oriented identity theorists can and should make, in addition to the first two claims, the third type-type identity claim that mental states are brain states. Consequently a token brain state is a token of pain in a derivative sense. What makes it a token of pain is that it is a token of the type of brain state which realizes the pain-rôle for the organism at the time. 相似文献

The concurrent and predictive validity of four qualitative behavioral classes of social interaction (initiating and receiving positive and negative social interaction) was investigated using sociometric measures of peer acceptance (ratings) and friendship (nominations). Correlational analyses showed significant relationships between behavioral and sociometric measures supporting previous work with preschool populations. Stepwise multiple regression analyses suggested that receiving social interaction from peers best predicted overall acceptance, whereas initiating social interactions best predicted children's friendship patterns. Tentative implications for the behavioral assessment of children's social skills were discussed.The current data were gathered as part of a larger research project concerning social skills assessment and training in children. 相似文献
