Our understanding of learning difficulties largely comes from children with specific diagnoses or individuals selected from community/clinical samples according to strict inclusion criteria. Applying strict exclusionary criteria overemphasizes within group homogeneity and between group differences, and fails to capture comorbidity. Here, we identify cognitive profiles in a large heterogeneous sample of struggling learners, using unsupervised machine learning in the form of an artificial neural network. Children were referred to the Centre for Attention Learning and Memory (CALM) by health and education professionals, irrespective of diagnosis or comorbidity, for problems in attention, memory, language, or poor school progress (n = 530). Children completed a battery of cognitive and learning assessments, underwent a structural MRI scan, and their parents completed behavior questionnaires. Within the network we could identify four groups of children: (a) children with broad cognitive difficulties, and severe reading, spelling and maths problems; (b) children with age‐typical cognitive abilities and learning profiles; (c) children with working memory problems; and (d) children with phonological difficulties. Despite their contrasting cognitive profiles, the learning profiles for the latter two groups did not differ: both were around 1 SD below age‐expected levels on all learning measures. Importantly a child's cognitive profile was not predicted by diagnosis or referral reason. We also constructed whole‐brain structural connectomes for children from these four groupings (n = 184), alongside an additional group of typically developing children (n = 36), and identified distinct patterns of brain organization for each group. This study represents a novel move toward identifying data‐driven neurocognitive dimensions underlying learning‐related difficulties in a representative sample of poor learners.  相似文献

This research examines (a) the interrelationships between body mass index (BMI), the direct measures of the Theory of Planned Behaviour (TPB) and physical activity intention and (b) the potential mediation effects of the direct measures of the TPB in the relationship between BMI and physical activity intention in a sample of Australian adults. A total sample of 1,062 respondents participated in a computer-assisted telephone-interview (CATI) survey comprised of a standardised introduction; questions regarding TPB and physical activity; and standard demographic questions. BMI for each participant was calculated from self-reported height and weight. Separate regression analyses were performed to examine the mediating effects of each of the direct measures of the TPB on the predictive relationship between the BMI and physical activity intention, as proposed by Baron and Kenny (Journal of Personality and Social Psychology, 51(6), 1173 - 1182, 1986). Findings indicated that the direct measure of attitude and perceived behavioural control mediated the relationship between BMI and physical activity intention. However, the direct measure of subjective norm failed to act as a mediating mechanism. To date there has been no research that has examined the mechanism by which body mass may affect physical activity behaviour. Given the current focus for health promotion specialists on promoting physical activity as a strategy for reducing overweight and obesity, a theoretical understanding of weight-related barriers to physical activity may aid in the development of future interventions and community physical activity programs, particularly those targeting overweight and obese populations.  相似文献

This study investigates the relationship between creative personality composition, innovative team climate, and team innovation based on an input‐process‐output model. We measured personality with the Creative Person Profile, team climate with the Team Climate Inventory, and team innovation through team‐member and supervisor reports of team innovativeness. The personality composition in each of 29 teams in a television production company was operationalized by mean scores for each creative personality variable, as well as the combination of different creative personality variables within a team. The team climate variable “vision” mediated the relationship between the mean level of associative orientation in teams and team innovation. The team climate variable “support of innovation” mediated the relationship between the joint variables of mean level of ambition x mean level of motivation and team innovation. The results indicated that when there are relationships between creative personality composition and team innovativeness, they are mediated by an innovative team climate.  相似文献

I discuss John Greco's paper 'What's Wrong with Contextualism?', in which he outlines a theory of knowledge which is virtue-theoretic while also being allied to a form of attributor contextualism about 'knows'.  相似文献

This study reports on the development and cross-national utility of a Likert type scale measuring attitudes toward unauthorized migration into a foreign country in two samples from "migrant-sending" nations. In the first phase a pool of 86 attitude statements were administered to a sample of 505 undergraduate students in Bulgaria (22.5% male; M age = 23, SD = 4.8). Exploratory factor analysis resulted in six factors, and a reduction to 34 items. The results yielded an overall alpha of (0.92) and alpha for subscales ranging from 0.70 to 0.89. In the second phase the 34-item scale was administered in a survey of 180 undergraduates from Sofia University in Bulgaria (16.7% male, M age = 23, SD = 4.8), plus 150 undergraduates from Hanoi State University in Vietnam (14.7% male, M age = 19, SD = 1.8). Results yielded a 19-item scale with no gender differences, and satisfactory alpha coefficients for a Vietnamese and Bulgarian sample of 0.87 and 0.89 respectively. This scale, equally applicable in both samples, includes items that reflect salient topics of concept of attitudes towards unauthorized migration. An exploratory principal component analysis of the Bulgarian and Vietnamese version of the 19-item scale yielded three factors accounting for 54% and 47% of the variance respectively. A procrustes analysis indicates high conceptual equivalence in the two samples for factor 1 and 2, and moderate for factor 3. This study lends support to the idea that despite different cultural meanings there is a common meaning space in culturally diverse societies.  相似文献

We examined how right-wing authoritarianism (RWA) influenced career and family plans and life outcomes in 2 samples of educated women. In the college-aged sample, participants who planned to earn professional degrees scored higher on RWA than those who planned to earn graduate degrees in the humanities or social sciences. RWA was also positively related to the expression of preferences for male partners who possess masculine characteristics. In the midlife sample, RWA scores were higher for participants with traditional career and family outcomes at midlife. For midlife participants following a nontraditional career path, RWA was positively related to compartmentalizing career and family responsibilities and finding role combination stressful. Authoritarianism is important for understanding women's decisions about combining career and family.  相似文献
