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

Previous studies have reported gender differences in patients’ health behaviours but few studied hypertensive patients. The potential underlying factors that may mediate gender influences on health behaviours is also a more critical area worthy of investigation. This study examined health locus of control (HLC) as a pathway of gender effects on health behaviours of hypertensive patients. The Multidimensional HLC Scale (Form C) and Wellness behaviour subscale of Health Behaviour Checklist were completed by 400 hypertensive outpatients in two Nigerian hospitals: Enugu State University Teaching Hospital, Park Lane, Enugu, and Bishop Shanahan Specialist Hospital, Nsukka. Hierarchical multiple regression results showed that gender significantly predicted health behaviours. Gender also significantly predicted internal HLC, chance HLC, and other people HLC, but did not predict doctor HLC. The association between gender and health behaviours was fully mediated by internal HLC, chance HLC and other people HLC. Understanding the explanatory mechanisms linking socio-demographic factors and health behaviours is considered of great importance for future research and healthcare intervention. 相似文献

Numerous studies have shown that viewing violence in the media can influence an individual's subsequent aggression, but none have examined the effect of viewing indirect aggression. This study examines the immediate effect of viewing indirect and direct aggression on subsequent indirect aggression among 199 children ages 11 to 14 years. They were shown an indirect, direct, or no-aggression video and their subsequent indirect aggression was measured by negative evaluation of a confederate and responses to a vignette. Participants viewing indirect or direct aggression gave a more negative evaluation of and less money to a confederate than participants viewing no-aggression. Participants viewing indirect aggression gave less money to the confederate than those viewing direct aggression. Participants viewing indirect aggression gave more indirectly aggressive responses to an ambiguous situation and participants viewing direct aggression gave more directly aggressive responses. This study provides the first evidence that viewing indirect aggression in the media can have an immediate impact on subsequent aggression. 相似文献

Stimulus-Response Compatibility Effects have been reported for several components of the reach-to-grasp action during visual object recognition [Tucker, M., & Ellis, R. (1998). On the relations between seen objects and components of potential actions. Journal of Experimental Psychology: Human Perception and Performance, 24, 830-846; Ellis, R., & Tucker, M. (2000). Micro-affordance: The potentiation of actions by seen objects. British Journal of Psychology, 91, 451-471; Tucker, M., & Ellis, R. (2001). The potentiation of grasp types during visual object categorization. Visual Cognition, 8, 769-800; Creem, S. H., & Proffitt, D. R. (2001). Grasping objects by their handles: A necessary interaction between cognition and action. Journal of Experimental Psychology: Human Perception and Performance, 27, 218-228; Craighero, L. Bello, A. Fadiga, L., & Rizzolatti, G. (2002). Hand action preparation influences the responses to hand pictures. Neuropsychologia, 40, 492-502]. The present study investigates compatibility effects for two elements of reach-to-grasp action during the visual mental imagery of objects-the compatibility of an object for grasping with a power and precision grasp, and the orientation of an object (left/right) for grasping by a particular hand (left/right). Experiment 1 provides further evidence for compatibility effects of a 'seen' object for grasping with a power and precision grasp. The experiment shows that compatibility effects are obtainable when an object is presented in an array of four objects and not just on its own. Experiment 2 provides evidence that compatibility effects of an object for grasping with a power and precision grasp can also be observed when participants make an action response to an object 700 ms after it has been removed from view. Experiment 3 investigates compatibility effects for the orientation of an object for grasping by a particular hand during visual mental imagery, but finds no evidence for such effects. The findings are discussed in relation to two arguments put forward to reconcile ecological and representational theories of visual object recognition. 相似文献

This article is based on the author's address at the National Multicultural Conference and Summit III in Los Angeles, California, in January 2003. The author focuses on culture as a resource--a resource for theories that can inform one's understanding of human behavior; a resource for healing, self-help, and positive emotions; a resource for clinical practice; and a resource for mental health and wellness. The author uses a healing story from native culture to describe the essence of his relational worldview and to reframe the professional thinking about culture as one of the greatest assets for healing and mental wellness rather than as a problem to solve. 相似文献

Using a serial reaction time task, this study examines whether learning of auditory sequences is possible without a corresponding motor response, i.e., by listening alone. The dual sequence paradigm used by Mayr (in Journal of the Experimental Psychology: Learning memory and cognition 22:350–354, 1996, Experiment 1) was adapted to the auditory domain. Four different actors spoke the same four colour words. These were presented such that speaker identity followed one sequence, and the word spoken followed a different sequence. Subjects were asked to respond (with a key press) to one of these dimensions (identity or word), and ignore the other. Results showed learning for either type of stimulus, but only when it was responded to. No learning of either type of auditory sequence by listening alone was found. The results add evidence to visual implicit learning studies that have failed to find learning of event sequences when spatial or response selection was not an important factor in processing. The findings are discussed in the context of implicit learning as a general and fundamental cognitive process. 相似文献

This paper presents a perspective on stigma as an effect of leprosy. It identifies some of the strengths and weaknesses of current approaches to stigma reduction in leprosy and presents a rationale for considering alternative strategies. It is suggested that models used to explain health behavior in developed societies are inappropriate for explaining leprosy stigma or for developing strategies to address it. The author recommends due consideration of the alternative logic that characterizes cultural belief systems in countries where leprosy is a challenge. Criticism of the common practice of information dissemination as a strategy to address leprosy stigma is defended and the merits and limitations of an integrated health service in India is discussed. The author defends the suggestion that the principal objective of stigma interventions should be "normalization". An example of a Nepalese project based on empowerment theory is given to demonstrate how the transformation of identity from outcast to positive change agent, can effect "normalization". 相似文献

The special status of spiders in the attentional bottleneck and visual working memory (VWM) was studied. 23 spider-fearfuls (SF) and 23 non-anxious controls (NACs) participated in a serial VWM-task. Each trial showed a 4 x 4 matrix of images and 5 of these were subsequently cued for 150 ms each. Afterwards, one of the 16 displayed images was hidden and probed. The spider image was included in the string of 5 cued images, among the 11 uncued items, or not at all. For both groups, memory was better for cued spiders than for other cued items. SFs also showed improved memory for uncued spiders. The relevance of the results for theories of attention and cognitive models of phobias are discussed. 相似文献

It has been suggested that affective states can guide higher level cognitive processes and that such affective guidance may
be particularly important when real-life decisions are made under uncertainty. We ask whether affect guides decisions in a
laboratory task that models real-life decisions under uncertainty. In the Iowa gambling task (IGT), participants search for
monetary payoffs in an uncertain environment. Recent evidence against an affective guidance interpretation of the IGT indicates
a need to set a standard for what counts as evidence of affective guidance. We present a novel analysis of IGT, and our results
show that participants’ galvanic skin response (GSR) reflects an affective process that precedes and guides cognition. Specifically,
prior to participants’ knowledge of the optimal strategy, their GSRs are significantly higher when they are about to select
from a bad deck, relative to a good deck, and this difference in GSR is correlated with a behavioral preference for the good
deck. 相似文献
