Studies investigating effect of practice on dual task performance have yielded conflicting findings, thus supporting different theoretical accounts about the organisation of attentional resources when tasks are performed simultaneously. Because practice has been proven to reduce the demand of attention for the trained task, the impact of long-lasting training on one task is an ideal way to better understand the mechanisms underlying dual task decline in performance. Our study compared performance during dual task execution in expert musicians compared to controls with little if any musical experience. Participants performed a music recognition task and a visuo-spatial task separately (single task) or simultaneously (dual task). Both groups showed a significant but similar performance decline during dual tasks. In addition, the two groups showed a similar decline of dual task performance during encoding and retrieval of the musical information, mainly attributed to a decline in sensitivity. Our results suggest that attention during dual tasks is similarly distributed by expert and non-experts. These findings are in line with previous studies showing a lack of sensitivity to difficulty and lack of practice effect during dual tasks, supporting the idea that different tasks may rely on different and not-sharable attentional resources. 相似文献
Introduction: Anxiety disorders are the most common mental illness in the general population, affecting 18% of the population in the United States (12 months prevalence) and 13.6% in Europe (life time prevalence). Several studies have also described high rates of anxiety disorders and symptoms of anxiety among the transgender population. There is, however, a great variation of results (particularly related to gender prevalence), and few studies have described the type of anxiety disorders specific to the transgender population.
Aim: To collect and critically appraise the information from the available studies describing prevalence rates of anxiety disorders and symptoms.
Results: A total of 25 cross-sectional (n = 17) and longitudinal (n = 8) studies were found. Cross-sectional studies described higher prevalence rates of anxiety symptoms in the transgender group than in the cis population. The prevalence of anxiety disorders range from 17% to 68%. The most common anxiety disorders found were specific phobias, social phobias, panic disorders, and obsessive-compulsive disorders. Most of the large studies suggest higher levels of anxiety symptoms and disorders in transgender men compared with transgender women; however, considerable variation in results was found.
Conclusions: The findings identified that there is considerable variation in anxiety disorders and symptoms among transgender people attending transgender health services. These findings are likely to be the result of the tools used, the lack of matching controls, and the lack of homogeneity of the group studied. Overall this review indicates high levels of anxiety symptoms and disorders among transgender people attending gender services, primarily (but not exclusively) before commencement of cross-sex hormone treatment. Anxiety disorders related to social interaction (such as social anxiety) and panic attack appear to be particularly common, however more rigorous studies to confirm those findings are needed. 相似文献
Anxiety sensitivity (AS), a well-established individual difference variable reflecting a tendency to fear bodily sensations associated with arousal, has been implicated in the development and maintenance of posttraumatic stress disorder (PTSD). Despite these associations, little research has examined the relations between AS subfactors (eg physical, cognitive, and social) and PTSD symptoms and none have examined these associations in the context of DSM-5 (Diagnostic Statistical Manual of Mental Disorders, Fifth Edition) PTSD clusters (ie intrusion, avoidance, negative alterations in cognitions/mood, and arousal). Participants included 50 veterans presenting to an outpatient Veteran Affairs Clinic for psychological services. Upon intake, veterans completed a brief battery of self-report questionnaires to assist with differential diagnosis and treatment planning. Results revealed unique associations between lower order AS dimensions, in particular the cognitive concerns dimension, and all four DSM-5 PTSD symptom clusters. Given the malleable nature of AS cognitive concerns, as well as the growing number of veterans in need of care, future research should determine the extent to which targeting this cognitive risk factor reduces PTSD symptom severity among veterans. 相似文献
Obsessive-compulsive disorder (OCD) commonly co-occurs with depression, resulting in heightened severity and poorer treatment response. Research on the associations between specific obsessive-compulsive symptoms (OCS) and depressive symptoms has utilized measures that have not fully considered the relationship across OCS dimensions. Little is known about which factors explain the overlap between OCS and depressive symptoms. OCS and depressive symptoms may be related via depressive cognitive styles, such as rumination or dampening (i.e., down-regulating positive emotions). We evaluated the associations of OCS dimensions with depressive symptoms and cognitive styles. We also examined the indirect effects of rumination and dampening in the relationship between OCS and depressive symptoms. Participants (N = 250) completed questionnaires online. Greater depressive symptoms, rumination, and dampening were associated with greater levels of all OCS dimensions. Path analysis was utilized to examine a model including the direct effect of depressive symptoms on overall OCS and two indirect effects (through rumination and dampening). There was a significant indirect effect of depressive cognitive styles on the relationship between OCS and depressive symptoms, through rumination and dampening. Replication in a clinical sample and experimental manipulations may bear important implications for targeting depressive cognitive styles in treatments for OCD and depression. 相似文献
Few studies have focussed on the link between anxiety and inhibitory control in the absence of stimulus-driven external threat. This two-part experiment examined the interactions between (1) somatic trait anxiety, somatic situational stress (i.e. threat of electric shock), and effort, and (2) cognitive trait anxiety, cognitive situational stress (i.e. ego-threat instructions), and effort, on inhibitory processes using a Go-No-Go paradigm. Trait anxiety was operationalised using questionnaire scores and effort was operationalised using a visual analogue scale. Performance effectiveness was measured using the d′ parameter from signal detection theory and processing efficiency was indexed by the ratio of d′ to response time on correct trials. Results indicated that somatic trait anxiety and stress did not predict effectiveness or efficiency. Cognitive trait anxiety and stress were associated with both inhibitory effectiveness and efficiency deficits; however, contrary to expectations these deficits were evident at higher rather than lower mental effort. Results suggest a distinction between how somatic and cognitive anxiety manifest on tasks involving inhibitory control. 相似文献
