The present studies examined the nature of visuo-spatial working memory development using conventional visual span and spatial span measures. Children aged between 6 and 13 years and adults aged 18-38 years were employed as participants. In Study 1, visual span, spatial span, articulation rate, and verbal fluency competencies were measured. In Study 2, visual span and spatial span maintenance was subject to five interference formats: nil, speech articulation, verbal fluency, visual masking, and spatial tapping. Distinct developmental rates were found for the two span tasks, which in the older children were correlated with the verbal fluency measure. Study 2 provided experimental evidence of the contribution of executive and spatial processes to spatial and to visual span maintenance. The results are interpreted as indicating that these memory span procedures make complex demands upon the visuo-spatial working memory architecture and consequently a precise identification of the process that actually develop is compromised. It is suggested that a componential approach where tasks are constructed to tap specific working memory components would afford a more accurate understanding of the development of these processes.  相似文献

Accurately recalling a complex multi-actor incident presents witnesses with a cognitively demanding retrieval task. Given the important role played by temporal context in the retrieval process, the current research tests an innovative timeline technique to elicit information about multiple perpetrators and their actions. Adopting a standard mock witness paradigm, participants were required to provide an account of a witnessed event. In Experiment 1, the timeline technique facilitated the reporting of more correct details than a free recall, immediately and at a two-week retention interval, at no cost to accuracy. Accounts provided using the timeline technique included more correct information about perpetrator specific actions and fewer sequencing errors. Experiment 2 examined which mnemonic components of the timeline technique might account for these effects. The benefits of exploiting memory organization and reducing cognitive constraints on information flow are likely to underpin the apparent timeline advantage.  相似文献

This article investigates the guardianship of fatherless children (orphans) in one of the most important Jewish communities of the thirteenth-century realms of Aragon, the aljama of the town of Perpignan. After reviewing some ideals of Solomon ben Abraham ibn Adret of Barcelona, as expressed in his responsa, the article focuses on documents of practice. This documentary basis includes royal charters, Latin wills of Jewish testators, and 148 unedited transactions generated by eighteen panels of guardians between 1266 and 1286, described in an analytical table at the end of the article. The practical evidence reveals that guardians usually served as a group, panels comprised close relatives of the wards and men who were distinguished in their community through official service. Case studies expose the dynamics within these panels and establish that the orphans' widowed mother usually acted as the group's leader. A comparison with her Christian counterpart places the rights and responsibilities of the Jewish widowed mother guardian into relief. Although not autonomous, Jewish widowed guardians were highly effective caretakers of their fatherless children. The idealized view of the Jewish widow held by her medieval contemporaries as helpless and in need of special care from the men of her community enabled already capable widows to benefit from the financial aid of community leaders who otherwise might not have been so keen to foster these women's legal and financial agency.  相似文献

The purpose of this study was to examine high and low body dissatisfied (BD) men's and women's in-task emotional responses to the acute exposure of sex-specific physique slides of the aesthetic ideal (i.e., ideal slides) and themselves (i.e., self-slides). Participants were 35 male and 30 female university students who reported their immediate in-task emotional responses (i.e., pleasure and arousal) to viewing the self- and ideal slides. It was found that the (a) high BD women reported the least amount of pleasure while viewing the self- and ideal slides; (b) women reported less pleasure while viewing the self-slides than did the men; (c) The high BD group reported less pleasure while viewing the self- vs. the ideal slides than did the low BD group, and (d) the high BD men reported the most arousal of any of the groups while viewing the self- and ideal slides. The differing emotional responses of the men and women and the high and low BD groups to viewing the self- vs. ideal slides are discussed, and future research directions are suggested.  相似文献

In this study, we examined attitudes toward poor women, stereotypes about them, attributions for their poverty, and whether these thoughts and feelings differ from those about poor men. In our Midwestern college students sample (n = 206), attitudes toward poor women were significantly more positive than attitudes toward poor men. In addition, stereotypes of poor women were both more positive and more consistent with gender stereotypes than were those of poor men. Participants endorsed internal attributions for the poverty of both women and men more strongly than external or cultural attributions. However, the content of these attributions was different for the two target groups. Poor women were held responsible for nontraditional familial and reproductive patterns, whereas poor men were held responsible for lack of initiative and self-improvement. For poor men, all types of attributions included references to ability or willingness to work. The three types of attributions were more conceptually distinct for poor women.  相似文献

Because television has the potential to shape cultural beliefs about both sexual norms and appropriate workplace behavior, it seems important to examine TV’s portrayal of “sexual etiquette” in the workplace. In a content analysis of two episodes of every primetime comedy aired on all broadcast and cable networks during fall 2000, we coded every sexual remark and behavior made in a workplace scene. Across all networks, 85 percent of programs and one in four workplace interactions contained some type of sexual content. Overall, a viewer is likely to hear eleven sexual remarks and see two to three sexual behaviors in a workplace setting per hour; this jumps to twenty-three remarks and nine behaviors on cable networks. Sexual remarks were mostly explicit, made in an office setting, by White men, and were rarely (1.4%) about sexual harassment or discrimination. Although sexual content in the workplace was generally less common on broadcast than cable networks, a broadcast network (Fox) actually had the highest overall rate, with sexual content in 38 percent of workplace scenes. Given that research suggests that TV teaches youth about sexuality and cultivates sexual attitudes and beliefs consistent with televised portrayals, it is alarming that youth may learn from television that sex in the workplace is not only commonplace, but also to be tolerated and enjoyed.  相似文献

The National Society of Genetic Counselors (NSGC) supports the development of practice recommendations (guidelines) in the field of genetic counseling. This paper reviews the basic components of NSGC genetic counseling practice recommendations as well as the process for formal adoption of such documents, as approved by the Board of Directors of the NSGC.  相似文献
