A number of neurobiological, psychological and social factors may account for cognitive impairment. In animal studies a relation between dental status and cognitive performance has been found. It is unclear whether such a relation exists for humans. In a first step we compared the performance of 1,351 participants (53% women, 47% men; age M = 54.0) with natural teeth to 487 edentulous participants (59% women, 41% men; age M = 71.3) on 12 cognitive tests. The natural teeth group had a lower mean age, fewer women, more years of education, higher mini-mental state (MMSE), and performed significantly higher on several cognitive tests. In a subsequent analysis, the cognitive performance of a subset of the participants (50-85 years) was examined. In this analysis, 211 had natural dentition and 188 were edentulous. The groups were matched for gender, age, social variables, diseases, stress and MMSE. The cognitive disadvantage of the edentulous group was still apparent. The results suggest that functional natural teeth relate to relatively preserved cognitive functioning in older age. 相似文献

Problem behaviour in schools may have detrimental effects both on students' well-being and academic achievement. A large literature has consistently found that school-wide positive behaviour support (SWPBS) successfully addresses social and behavioural problems. In this paper, we used population-wide longitudinal register data for all Norwegian primary schools and a difference-in-difference (DiD) design to evaluate effects of SWPBS on a number of primary and secondary outcomes, including indicators of externalising behaviour, school well-being, pull-out instruction, and academic achievement. Indications of reduced classroom noise were found. No other effects were detected. Analyses revealed important differences in outcomes between the intervention and control schools, independent of the implementation of SWPBS, and that a credible design like DiD is essential to handle such school differences. 相似文献

The pigeon is a standard animal in comparative psychology and is frequently used to investigate visuocognitive functions.
Nonetheless, the strategies that pigeons use to discriminate complex visual stimuli remain a difficult area of study. In search
of a reliable method to identify features that control the discrimination behaviour, pecking location was tracked using touch
screen technology in a people-absent/people-present discrimination task. The correct stimuli contained human figures anywhere
on the picture, but the birds were not required to peck on that part. However, the stimuli were designed in a way that only
the human figures contained distinguishing information. All pigeons focused their pecks on a subarea of the distinctive human
figures, namely the heads. Removal of the heads significantly impaired performance, while removal of other distinctive parts
did not. Thus, peck tracking reveals the location within a complex visual stimulus that controls discrimination behaviour,
and might be a valuable tool to reveal the strategies pigeons apply in visual discrimination tasks. 相似文献

This study aimed to explore fathers’ mental health and retrospectively reported adverse childhood experiences during pregnancy, as well as various pathways predicting self‐reported stress at 6 months’ postpartum as assessed by the Parenting Stress Index (PSI; R.R. Abidin, 1990 ). A total of 835 fathers contributed data to the study. Data collection comprised five time points during pregnancy and one at 6 months’ postpartum. The main analyses were performed using linear regression and path analyses. First, linear regression analyses showed that paternal anxiety symptoms during pregnancy predicted stress scores in the PSI child domain at 6 months (coefficient = 0.36). Second, path analyses showed that depressive symptoms during pregnancy predicted parenting stress in the child domain, mediated by spousal disharmony at 6 months’ postpartum (coefficient = 0.77). Third, adverse childhood experiences scores predicted parenting stress in the child domain by two different pathways: one mediated by anxiety symptoms in pregnancy (coefficient = 0.29) and the other by depressive symptoms in pregnancy and experienced spousal disharmony at 6 months’ postpartum (coefficient = 0.77). The findings suggest that fathers’ symptoms of anxiety and depression during pregnancy as well as adverse childhood experiences predict paternal stress and a negative perception of their children's behavior at 6 months’ postpartum. 相似文献
