ABSTRACTThis work examines differences in the work-related values, expectations, and behaviors between millennials who are significant users of technology and social media, and those who are not. We delineate the development of millennial behavior using a unique group of millennials, those in the Ultra-Orthodox Jewish (known as “Haredi”) community in Israel. Due to religious and community norms, many Haredi millennials were shielded from digital technology, and particularly the Internet and the various technologies associated with it, such as text messaging and social media. Those who were raised and remained in Haredi communities did not encounter the Internet with any regularity as children. Many as adults are still unfamiliar with social media. Thus, this community presents a unique natural experiment, comparing Haredi millennials who are immersed in social media with those who are not. 相似文献

This article contains detailed reviews of 13 computerized neuropsychological and performance test batteries and six stand-alone computer tests. Tasks found on these instruments are described and tables illustrate which batteries employ which measures. In addition to issues of reliability and validity, special considerations apply to computerized assessment. These issues are discussed and readers are provided information to help them assess computerized tests in relation to their particular clinical and research needs. Since many computerized tests were developed as performance assessment tools, the relationship between performance and neuropsychological assessment is examined. 相似文献

Confirmatory factor analyses of the 15 cognitive abilities tests from the Hawaii Family Study of Cognition were conducted on between-family (BF) means and within-family (WF) differences for 370 AEA (Americans of European ancestry) and 116 AJA (Americans of Japanese ancestry) sibling pairs. Difference chi-square significance tests, goodness-of-fit indices, and congruence coefficients for the estimated loadings on four specific cognitive abilities factors and on the second-order general intelligence factor nearly all indicated that the between-family factor structures were not significantly different from the within-family structures for both AEA and AJA siblings (the AEA and AJA structures were also not significantly different). The similarity of the BF and WF structures suggests that the genetic and environmental influences underlying cognitive abilities are “intrinsic” in nature, that is, not just due to between-family differences in culture, status, values, and fortuitous cross-assortative mating. 相似文献

Summary Simple motor responses of different similarity were assigned to geometric figures of different similarity. Subsequently, subjects had to learn hierarchical classifications of visually similar or dissimilar figures which were associated with either similar or dissimilar responses. In this way, the visual and the functional similarity of the conceptually united figures were orthogonally varied. It was found that visually similar figures are conceptually classified fastest regardless of their functional similarity. In contrast, functional similarity has a considerable impact on the hierarchical classification of visually dissimilar figures. Functionally similar figures are conceptually faster classified than dissimilar ones. From the results we conclude that concepts are autonomously formed as mediating representations in stimulus-response coordinations. The hierarchical organization of concepts is thereby based on the sequential organization of both the visual input and the behavioral output. Further consequences of this approach are discussed.Portions of this research were presented at the International Symposium on Structure and Function of Human Memory, in Memoriam Hermann Ebbinghaus, Berlin, July 1985 相似文献

Hispanics in Ivy: Assessing identity and perceived threat 总被引:1,自引:0,他引:1
Membership in social groups is an important aspect of the self-concept, as a number of theorists such as Tajfel (1981) have recognized, and ethnic identity is a major exemplar of such groupings. In the present research, we focus on the particular case of Hispanic identity and the degree to which that identity may be threatened for first-year Hispanic students who enter a predominantly Anglo university. Forty-five Hispanic students (17 female, 28 male) at two Ivy League universities were interviewed early in their first year to assess Hispanic identity, collective self-esteem (Luhtanen & Crocker, 1988), and perceived threats to Hispanic identity. In addition, we considered the degree to which strength of cultural background relates to self-esteem and to perceptions of threat. The majority of students claimed Hispanic as an important identity. Strength of cultural background generally acted as a buffer to perceived threat, particularly for men. Cultural background was also related to collective self-esteem for men but not for women, even though Hispanic identity was more important for women than men. The results attest to the importance of both gender and ethnicity to self-definition and self-esteem, as well as to the complexity of the relationships among these variables.We thank Tracey Revenson as well as the members of the Identity Research Seminar at the CUNY Graduate Center for their comments on an earlier version of this paper. 相似文献

Previous research indicates that low scores on the Raven's Advanced Progressive Matrices (RAPM) test are associated with increased cortical glucose utilization during problem solving. We hypothesized that previous results may reflect the neurophysiological consequences of patterns of effort requirements; that is, high-effort expenditure from lower aptitude participants (for whom the problems are hard) and low-effort expenditure from higher aptitude participants (for whom the problems are easy). In this experiment, positron emission tomography (PET) data were gathered on participants (N = 28) who solved easy and hard problems that were tailored to the participants' own ability levels, thereby eliminating aptitude group differences in effort requirements. Contrary to previous results, high aptitude was associated with high cortical glucose use. Average aptitude participants showed diminished glucose use in the hard condition. A significant Group X Condition X Hemisphere Effect was also noted, with greater right hemisphere activation in the hard condition for the high-aptitude group. These results demonstrate that the relation of cerebral glucose use and cognitive ability is sensitive to participant and task selection. 相似文献

This study considers how high school students perceive incidents of possible sexual harassment toward students and how they define sexual harassment. Thirty-five male and 38 female high school seniors (44% Asian-American; 40% white, non-Hispanic; 6% Indian-American; 4% African-American; 3% Hispanic; and 3% other ethnic groups) evaluated scenarios that varied the type of sexual harassment, the status of the initiator (either teacher or student), and the gender composition of the dyad (either male toward female or female toward male). As predicted, type of harassment influenced ratings of severity. Compared to male respondents, female respondents rated the scenarios as more severe. Teachers were judged more critically than students. Differences in status were more apparent at less severe levels of harassment. In defining harassment, students relied on four factors: the behavior itself, the target's reaction to the behavior, the perpetrator's intentions, and the relationship that existed between the two people. Overall, the findings underline the importance of examining high schools as a locale for harassment.This study was originally conducted by the first author as a Westinghouse Science project at Stuyvesant High School, with the guidance of the second and third authors. 相似文献
