The Leiter-3 is a nonverbal assessment that evaluates cognitive abilities and has been adapted for use in Scandinavia. Generalizability of United States-based normative scoring for use with the Scandinavian population was evaluated. Leiter-3 scores from a sample of Scandinavian students were compared with scores obtained from the Leiter-3 standardization sample, controlling for confounding variables, across ages, using mixed-methods analysis. A Scandinavian-population-based sample was created from Leiter-3 standardization data and norms were constructed and were used to generate standardized scores from the sample data. Results suggest that overall the Scandinavian test-takers score higher than American test-takers, but that differences between groups were minimized when controlling for factors that may influence cognitive performance. Creating Scandinavian based scores was not effective at reducing gaps in performance, suggesting that differences in performance between the different populations may be attributable to factors other than those typically controlled for when constructing standardized tests. Implications of these results and recommendations for Leiter-3 adaptation are reviewed.  相似文献

The mathematical problem of approximating one matrix by another of lower rank is closely related to the fundamental postulate of factor-theory. When formulated as a least-squares problem, the normal equations cannot be immediately written down, since the elements of the approximate matrix are not independent of one another. The solution of the problem is simplified by first expressing the matrices in a canonic form. It is found that the problem always has a solution which is usually unique. Several conclusions can be drawn from the form of this solution.A hypothetical interpretation of the canonic components of a score matrix is discussed.  相似文献

Stressful situations hinder judgement. Effects of stress induced by anticipated public speaking on the Iowa Gambling Task (IGT) were examined. The Cognitive Reflection Test (CRT) was used to examine the relationship between reflective thinking and IGT performance. The stress manipulation increased blood pressure and was associated with poorer IGT and CRT performance. Stressed participants were slower to avoid the disadvantageous decks. Moreover, CRT scores correlated with optimal deck selections indicating the importance of reflective thinking for good performance on the IGT. These correlations were observed in relatively early trials, which challenges the view that analytic thinking is not important when card contingencies are being learned. Data revealed that IGT performance in healthy individuals is not always optimal; stress levels impair performance. A mediation analysis was consistent with the proposal that the stress manipulation reduced IGT performance by impeding reflective thinking. Thus, reflective processing is an important explanation of IGT performance in healthy populations. It was concluded that more reflective participants appear to learn from the outcomes of their decisions even when stressed. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Prior research suggests that fruit and vegetable intake predicts psychological well-being (WB) when controlled for demographic variables such as age, income and education. Using multiple-item measures and including additional diet and health variables as covariates, the current study assessed self-reported well-being in the past week and daily fruit and vegetable consumption over the past 4 weeks for 1270 university students. Mean positive affect increased linearly as a function of number of daily servings of fruits and vegetables; the pattern of this relationship did not differ significantly for males and females. This association remained statistically significant after controlling for demographic variables (age, sex, and parent education levels); other diet variables (consumption of sugar containing beverages, coffee or tea, and fat); and other health behaviors (exercise, sleep quality and smoking). Life satisfaction and negative affect were not significantly related to fruit and vegetable consumption. Analysis of single-item measures similar to those used in past large scale surveys yielded similar results. Possible reasons for the association of fruits and vegetable consumption with well-being are discussed.  相似文献

Reentry research has received much less attention than research on cultural adjustment in a foreign country, especially in the marriage and family therapy (MFT) field in the United States. Lack of research on international students’ job experiences and professional developments during reentry does not provide further information to evaluate the quality of MFT education in the United States. This study was intended to extend the reentry literature and specifically to understand personal and professional reentry experiences and cross-cultural transformation of MFT returnees in Taiwan. Thirteen participants were interviewed, and the resulting data was analyzed using constructivist grounded theory. Analyses results demonstrated macro contextual factors that situated unique personal and professional reentry phenomena for international MFT graduate in Taiwan. The returnees strived to explore their MFT identity and interpret cross-cultural differences by developing four coping strategies (e.g., not wanting to fit in, doing what you were supposed to do or could do, processing with others, and therapists’ multicultural awareness) that were associated with three conditions, such as personal networks linking to professional networks, supervision, and training in MFT. Findings suggested that reentry adaption was varied and fitting into Taiwanese society might not be the final goal for the returnees. Training implications in the MFT field were provided based on the findings.  相似文献

It has been argued that greater intra-category structural similarity for living things, and the subsequent "visual crowding," makes them more difficult to recognize and name for neurologically damaged individuals and normal subjects (Humphreys et al., 1988). Nevertheless, the precise meaning and quantification of structural similarity remains unclear, as does the rationale for why it necessarily should be greater for living things. We derived a new measure of visual overlap from the Snodgrass and Vanderwart corpus of line drawings: the degree of pixel overlap within subcategories (Euclidean distance: ED). Contrary to existing notions of visual crowding and extant measures of contour overlap, within-category ED indicated less within-category visual overlap for living things. Furthermore, musical instruments clustered with living things (having low overlap), while body parts clustered with nonliving things (having high overlap). These counter-intuitive findings accord with patient data and thus, provide evidence for the psychological reality and utility of ED.  相似文献

Lower cognitive ability is a risk factor for some forms of severe psychiatric disorder, but it is unclear whether it influences risk of psychological distress due to anxiety or the milder forms of depression. The participants in the present study were members of two British birth national birth cohorts, the 1958 National Child Development Survey (n = 6369) and the 1970 British Cohort Study (n = 6074). We examined the association between general cognitive ability (intelligence) measured at age 10 (1970 cohort) and 11 years (1958 cohort) and high levels of psychological distress at age 30 (1970 cohort) or 33 years (1958 cohort), defined as a score of 7 or more on the Malaise Inventory. In both cohorts, participants with higher intelligence in childhood had a reduced risk of psychological distress. In sex-adjusted analyses, a standard deviation (15 points) increase in IQ score was associated with a 39% reduction in psychological distress in the 1958 cohort and a 23% reduction in the 1970 cohort [odds ratios (95% confidence intervals) were 0.61 (0.56, 0.68) and 0.77 (0.72, 0.83), respectively]. These associations were only slightly attenuated by further adjustment for potential confounding factors in childhood, including birth weight, parental social class, material circumstances, parental death, separation or divorce, and behaviour problems, and for potential mediating factors in adulthood, educational attainment and current social class. Intelligence in childhood is a risk factor for psychological distress due to anxiety and the milder forms of depression in young adults. Understanding the mechanisms underlying this association may help inform methods of prevention.  相似文献
