Human recognition memory shows a decline during normal ageing, which is thought to be related to age-associated dysfunctions of mediotemporal lobe structures. Whether the hippocampus is critical for human general relational memory or for spatial relational memory only is still disputed. The human perirhinal cortex is thought to be critically involved in non-relational memory, but another view postulates hippocampal involvement in both relational and non-relational memory. Investigating whether there is a differential impact of ageing on these memory processes may shed further light into these issues. Thus, in the present study, 106 healthy adults performed three recognition memory tasks in a consecutive age groups design involving a range from age 20 to 76. This allowed the separate assessment of spatial and nonspatial relational memory as well as non-relational memory. Both spatial and nonspatial relational memory declined in the 66-76 yr group. This pattern is consistent with the presumed course of hippocampal changes across normal ageing and points to the hippocampal role in relational memory in general. An impairment of non-relational memory commenced earlier in the 51-65 yr group. This finding is discussed in relation to perceptual/attentional mediation of memory and its potential brain correlates in ageing. 相似文献

This study included a review and content analysis of international career articles published in four major U.S. vocational/career journals over a 34-year time period. Three hundred and twenty-six articles were identified, constituting 2.4% of the total number of articles published in these journals during this time. The results showed an increasing number of international career articles being published over time and that most of them are empirically based, with adult professionals as the most common sample type. The two most common content areas identified were Career Issues Related to a Specific Culture, Country, or Population and Academic and Vocational Attitudes. Further, a substantial amount of these publications originated from institutions in Israel. Implications for practice and future research are discussed. 相似文献

INTRODUCTION: Few studies have examined racial differences in perceptions of childhood. Little is known about how Blacks perceive their own families, particularly the family environment that they experienced in childhood. METHODS: A community sample of 290 women (55% White, 45% Black) from two-parent families, heterogeneous in age and social class, was examined using a self-administered questionnaire, including the Family Environment Scale (FES), followed by a focused interview. Siblings were used as collateral informants. RESULTS: The psychometric properties of the FES showed remarkably little variation by race: The internal scale reliability, correlations between scales, and factor structures were quite similar. Although both White and Black women reported good childhood family environments, Black women when compared with White women rated their families of origin as more cohesive, organized, and expressive, and lower in conflict. Sibling responses corroborated these findings. DISCUSSION: This study addresses a gap in the research literature and provides important evidence of strengths in Black family relationships as reported by a community sample of women. The psychometric properties of the FES, found to be strong for families of both races, lends support to our findings and those of other researchers who have used this measure. 相似文献

In three experiments we examined whether memory for object locations in the peri-personal space in the absence of vision is affected by the correspondence between encoding and test either of the body position or of the reference point. In particular, the study focuses on the distinction between different spatial representations, by using a paradigm in which participants are asked to relocate objects explored haptically. Three frames of reference were systematically compared. In experiment 1, participants relocated the objects either from the same position of learning by taking as reference their own body (centred egocentric condition) or from a 90 degrees decentred position (allocentric condition). Performance was measured in terms of linear distance errors and angular distance errors. Results revealed that the allocentric condition was more difficult than the centred egocentric condition. In experiment 2, participants performed either the centred egocentric condition or a decentred egocentric condition, in which the body position during the test was the same as at encoding (egocentric) but the frame of reference was based on a point decentred by 90 degrees. The decentred egocentric condition was found to be more difficult than the centred egocentric condition. Finally, in experiment 3, participants performed in the decentred egocentric condition or the allocentric condition. Here, the allocentric condition was found to be more difficult than the decentred egocentric condition. Taken together, the results suggest that also in the peripersonal space and in the absence of vision different frames of reference can be distinguished. In particular, the decentred egocentric condition involves a frame of reference which seems to be neither allocentric nor totally egocentric. 相似文献

Do economic indicators predict the general level of support for gender equality? This question was investigated in a sample of countries in Central and Eastern Europe, a region that has been undergoing rapid economic changes since the early 1990s. In this overall sample of male and female college students from ten countries, including the United States as a comparison, the predicted association between stronger beliefs in gender role egalitarianism and positive economic factors was generally supported. Also, consistent with other research, women were more in support of gender equality than men were. There was no support for a predicted trend in less support for gender equality over the time period of the present study. 相似文献

Common experiences of mothering offer profound critiques of maternal ethical norms found in both Christianity and Islam. The familiar responsibilities of caring for children, assumed by the majority of Christian and Muslim women, provide the basis for reassessing sacrificial and selfless love, protesting unjust religious and political systems, and dismantling romanticized notions of childcare. As a distinctive category of women's experience, motherhood may offer valuable perspectives necessary for remedying injustices that afflict mothers and children in particular, as well as for developing cross‐cultural understandings of justice in general. 相似文献
