Previous systematic reviews and meta-analyses have identified cognitive deficits in adults with obstructive sleep apnoea (OSA). However, quantitative analysis of the association between OSA and neuropsychological performance has not been conducted specifically in older adults, for whom there is a greater risk of cognitive decline. We searched Medline, Embase and PsycINFO through August 2016 for studies describing associations between OSA and neuropsychological outcomes in people aged>50 years. Meta-analyses were performed on these studies for overall cognition and within cognitive domains. Subgroup analyses were performed taking into account risk of bias and moderating differences in study design. 13 studies met eligibility criteria for analysis. A small negative association was found between OSA and all neuropsychological outcomes combined, g=0.18(95% CI 0.04–0.32), and in memory and processing speed domains. Small case-control studies from sleep clinic populations observed the greatest associations, while larger cohort studies from community samples illustrated no association. Analysis accounting for publication bias resulted in a null overall association, g=0.02 (95%CI -0.12 to 0.16). Associations between OSA and cognition in later life are highly variable and the findings differ based on the type and setting of study. It appears some older adults may be at risk of cognitive impairments attributable to OSA; however, the risk of bias renders the evidence inconclusive. High quality research is warranted in clinically diagnosed OSA patients as well as those already experiencing neuropsychological impairment and who may be regarded at higher risk of further cognitive decline. 相似文献

Children and adolescents with learning disabilities (LD) are vulnerable to psychosocial difficulties. Both the detrimental impact of LD on social adjustment and the significance of peer relations for developmental needs make group therapy a natural intervention. Despite modifications that are required due to their cognitive deficits, many students with LD fit the criteria and can benefit from group psychotherapy. In this paper, a model of group therapy for older children and adolescents with LD is presented. The approach is informed by a combination of self psychology, mutual aid, and interpersonal group therapy. The leaders use special techniques to accommodate the LD and to foster the group process. Examples are presented to illustrate the approach. 相似文献

Risk avoidance: Graphs versus numbers 总被引:1,自引:0,他引:1
There have long been speculations that graphical and numerical presentations of risk statistics differ in their impact on
people’s willingness to pursue actions that could harm or even kill them. But research has been unclear about the processes
whereby the pictorial character of graphical displays per se might affect those risky decisions or even whether such effects
actually occur. In two studies, we demonstrate that the pictorial nature of a graphical risk display can, indeed, increase
risk avoidance. This increase is associated with a heightened impression of the riskiness of less safe alternatives. The results
suggest that this picture-driven, intensified sense of riskiness, in turn, rests on two kinds of mechanisms: one cognitive,
the other affective. Cognitively, pictorial presentations impose weaker upper bounds on people’s internal representations
of the chances that riskier alternatives will bring about actual harm. Affectively, pictures ignite stronger, more aversive
negative associations with riskier options and their outcomes. 相似文献

The Influence of Cultural and Racial Identification on the Psychosocial Adjustment of Inner-City African American Children in School 总被引:2,自引:0,他引:2
The purpose of this study was to examine the relationship and combined influence of racial identity and Africentric values on African American children's psychosocial adjustment. Participants were 104 (53 males, 51 females) African American fourth-grade students attending an inner-city public school in a northeastern city. Child and teacher ratings were used to assess the relationship between racial identity, Africentric values, and several indices of child psychosocial adjustment, including child behavior control, school interest, and teacher perceptions of child strengths and problems in the classroom. Child self-esteem and the effects of gender and cohort were used as covariates in several analyses in the study. Overall, findings from the study supported the usefulness of combining racial identity and Africentric values into a single model of ethnic identification for African American children. Implications for risk prevention and enhancement of psychosocial functioning among African American children are discussed. 相似文献

Executive control is impaired from the early stages of Alzheimer's Disease (AD) and this produces deregulated semantic cognition (Corbett, Jefferies, Burns, & Lambon Ralph, 2012 ; Perry, Watson, & Hodges, 2000 ). While control deficits should affect semantic retrieval across all modalities, previous studies have typically focused on verbal semantic tasks. Even when non‐verbal semantic tasks have been used, these have typically employed simple picture‐matching tasks, which may be influenced by abnormalities in covert naming. Therefore, in the present study, we examined 10 patients with AD on a battery of object‐use tasks, in order to advance our understanding of the origins of non‐verbal semantic deficits in this population. The AD patients’ deficits were contrasted with previously published performance on the same tasks within two additional groups of patients, displaying either semantic degradation (semantic dementia) or deregulation of semantic retrieval (semantic aphasia; Corbett, Jefferies, Ehsan, & Lambon Ralph, 2009 ). While overall accuracy was comparable to the scores in both other groups, the AD patients’ object‐use impairment most closely resembled that observed in SA; they exhibited poorer performance on comprehension tasks that placed strong demands on executive control. A similar pattern was observed in the expressive domain: the AD and SA groups were relatively good at straightforward object use compared to executively demanding, mechanical puzzles. Error types also differed: while all patients omitted essential actions, the SA and AD groups’ demonstrations also featured unrelated intrusions. An association between AD patients’ object use and their scores on standard executive measures suggested that control deficits contributed to their non‐verbal semantic deficits. Moreover, in a task specifically designed to manipulate executive demand, patients with AD (and SA) exhibited difficulty in thinking flexibly about the non‐canonical uses of everyday objects, especially when distracted by semantically related objects. This study provides converging evidence for the notion that a failure of regulatory control contributes to multimodal semantic impairment in AD and uniquely demonstrates this pattern for the highly non‐verbal domain of object use. 相似文献

Sleep is known to play an active role in consolidating new vocabulary in adults; however, the mechanisms by which sleep promotes vocabulary consolidation in childhood are less well understood. Furthermore, there has been no investigation into whether previously reported differences in sleep architecture might account for variability in vocabulary consolidation in children with dyslexia. Twenty‐three children with dyslexia and 29 age‐matched typically developing peers were exposed to 16 novel spoken words. Typically developing children showed overnight improvements in novel word recall; the size of the improvement correlated positively with slow wave activity, similar to previous findings with adults. Children with dyslexia showed poorer recall of the novel words overall, but nevertheless showed overnight improvements similar to age‐matched peers. However, comparisons with younger children matched on initial levels of novel word recall pointed to reduced consolidation in dyslexics after 1 week. Crucially, there were no significant correlations between overnight consolidation and sleep parameters in the dyslexic group. This suggests a reduced role of sleep in vocabulary consolidation in dyslexia, possibly as a consequence of lower levels of learning prior to sleep, and highlights how models of sleep‐associated memory consolidation can be usefully informed by data from typical and atypical development. 相似文献

This study examined sex differences in persuasibility at differing levels of topic involvement. A pilot study was conducted to select topics which were of high and low involvement and which did not show sex differences in terms of agreement, interest or information about the topics. Subjects were 296 Introductory Psychology students. Pre-test and post-test measures were obtained as a measure of opinion change. Control groups were used to control for effects of testing, maturation, and other threats to internal and external validity. The treatment consisted of written persuasive communications arguing against the opinions previously reported by a majority of subjects. Contrary to most previous research, results indicated that there were no significant sex differences or interactions in persuasibility using topics of low or high involvement. 相似文献

We looked at relationships between academic women's feminist identity and their perceptions of discrimination. From a sample of self-labeled feminist professors of psychology who had participated in the Feminist Teaching Project, we examined previously transcribed interviews and also collected new, auxiliary information. We expected to find that our respondents would view feminism as both provoking discrimination and helping them cope with discrimination. We found that experiences with gender discrimination were common among our sample, but that feminism in isolation was not perceived by our respondents as a provocation for problems. Rather than making it hard for women to swim in academic waters, feminism seemed to serve as a life raft for many professors. 相似文献
