Stroke is the main cause of acquired disability in adults, and specific deficits in working memory (WM) are among the most common cognitive consequences. In neuropsychological routine, WM is most of the time investigated in the framework of the multicomponent model (Baddeley & Hitch, 1974, The psychology of learning and motivation, 47). Using a more recent theoretical WM model, the time-based resource-sharing (TBRS) model (Barrouillet et al., 2011, Psychol. Rev., 118, 175), the aim of the present study was to investigate in young post-stroke patients to which extent attentional maintenance is impaired in WM. To address this question, we discarded other factors known to directly influence WM performance, that is processing speed and short-term memory span. We proposed to 53 post-stroke patients and to 63 healthy controls a complex span paradigm in which participants were asked to alternate between the memorization of a series of images and a concurrent parity judgement task of a series of digits. To investigate the attentional maintenance processes, we manipulated the cognitive load (CL) of the concurrent task. CL effect is typically interpreted as the involvement of attentional maintenance processes. The task was adapted to each participant according to their processing speed and memory span. As expected, the results showed higher recall performance in healthy controls compared with post-stroke patients. Consistent with the literature, we also observed higher performance when the CL was low compared with high. However, the improvement in recall at low CL was smaller for post-stroke patients compared with controls, suggesting that post-stroke WM deficit could be in part due to a deficit of the attentional maintenance processes.  相似文献

The focus of the present study is the relationship between Masculine and Feminine personality attributes (as measured by the PAQ), sex role attitudes, and socialization antecedents among a sample of Black women. The majority of the Black women in this study report Androgynous sexual identities, but have traditional beliefs about the female role in the family. Androgynous women are more likely to be positively identified with both mother and father. Women who are college graduates have more liberal views about the female role and are more likely to identify themselves as Masculine and Undifferentiated. Regardless of sexual identity category, the subjects are all heavily invested in the mothering role. Racial comparisons indicate more Black women are in the Androgynous category and more White women in the Undifferentiated category. White respondents have more liberal sex role attitudes than the Black respondents.  相似文献

The use of, and satisfaction with, counselling and social care services was investigated among HIV-infected clients attending HIV specialist climes at Guy's Hospital and Southwark Social Services, London. A survey of 71 clients with HIV infection was carried out using a self-administered questionnaire. The greatest demand was for advice about income support, housing, counselling for the HIV test, counselling for depression or anxiety, psychological support for coping with HIV, help with sleeping problems, mobility allowance, and help with furniture/household appliances. Overall, 57% thought the service was good or excellent; 66% of respondents thought they would use the services in the future. Over nine in ten clients had used the psychosocial support services at some stage since their HIV diagnosis, although only two-thirds anticipated that they would have need of these services in the future. The psychosocial support service will need to remain responsive to the shift in demand for this service, as well as the changing needs of clients who use it.  相似文献

In this introduction to the papers in the special issue of Sex Roles on female aggression, I emphasize the range and variety of our subject and the need for a multiplicity of perspectives. In the work of the eleven authors contained in this volume we can see the utility of both relativist and universalists frameworks. I discuss the problems with identifying aggression and violence cross-culturally and underline the importance of incorporating other perspectives into our theories. I also discuss the potential advantages and shortcomings of phrasing our questions about women's and girls's aggression in terms of sexual difference.  相似文献

Teacher stress and guidance work in Hong Kong secondary school teachers   总被引:2,自引:0,他引:2  
Major sources of stress in Hong Kong teachers were investigated, with specific reference to guidance work as a potential source of stress. A survey of 415 secondary school teachers revealed that guidance-related aspects of work constituted a major dimension of stress, with guidance teachers, female teachers, younger teachers and junior teachers perceiving more stress than their counterparts in this dimension. Workload and time pressure were perceived as the most stressful aspects of work for all teachers. Results also showed an association between stress and job satisfaction, and biographical variables. Implications of the findings for teachers doing guidance work in Hong Kong and internationally are discussed.  相似文献

Compassion is an emotion that occupies a central position in Mahāyāna Buddhist philosophy while it is often a neglected subject in contemporary western philosophy. This essay is a comparison between an Eastern view of compassion based upon Mahāyāna Buddhist perspectives and a western view of the same emotion. Certain principles found in Mahāyāna Buddhist philosophy such as the Bodhisattva Ideal, and suffering (dukkha) to name two, are explored for the information they contain about compassion. An essay by Lawrence Blum is taken as representative of a Western view (but not exclusively) and it is analyzed for its shortcomings in light of the Buddhist view. The conclusion briefly describes the value of understanding an eastern view on compassion as a means of filling the void one finds in western medical ethics discourse which focuses so heavily, and redundantly, upon issues such as patient autonomy and paternalism.  相似文献

Examined postpartum effects of a school-based intervention program for pregnant adolescents. Interviews were conducted with 102 innercity black, low-income, school-aged mothers who had attended the program, and their academic and medical records were reviewed. For teenagers who had been poor students prior to becoming pregnant, a strong linear effect was found for duration of program attendance: with sufficient time in the program, poorer students became indistinguishable from better students in educational success. Most of the better students were educationally successful at 2 years postpartum, independent of their length of time in the program. For all students, longer durations of postnatal intervention were predictive of lower likelihood of subsequent childbearing. Numerous academic, medical, social, and demographic variables were ruled out as possible confounding factors that might have produced the positive educational outcomes for poorer students. The results suggest that adolescents who appear to have minimal academic promise prior to their pregnancy are nevertheless very responsive to school-based intervention.  相似文献
