The authors investigated whether the size of the attention focus can influence saccadic adaptation, and whether this influence changes in older age. Using the scrambled sentence task, young and older participants were either primed for a wide attention focus, or primed of a narrow attention focus, or were not primed for any specific attention focus. Subsequently, all participants underwent a double-step saccadic adaptation paradigm aimed at changing the direction of reflexive saccades. The authors found that compared to the nonprimed control group, priming for a wide attention focus enhanced saccadic adaptation in both age groups by a similar amount; the benefit persisted throughout the adaptation phase, but was absent during the deadaptation phase. In contrast, the authors found no effects of priming with a narrow attention focus on saccadic adaptation. From this the authors conclude that a wide attention focus is beneficial for workaround strategies but not for adaptive recalibration, and that those benefits are similar in young and older persons.  相似文献

Multitiered systems of support depend on screening technology to identify students at risk. The purpose of this study was to examine the use of a computer-adaptive test and latent class growth analysis (LCGA) to identify students at risk in reading with focus on the use of this methodology to characterize student performance in screening. Participants included 3,699 students in Grades 3–5. Three time points of administration (fall, winter, and spring) of the computer-adaptive reading measure were selected. LCGA results indicated 6–7 classes, depending on grade, informed by level and growth in student performance that significantly predicted failure on the statewide test administered at the end of the year. The lowest-performing classes had failure rates above 90% across all grades. The results indicate that identifying homogeneous groups of learners through LCGA may be valuable as an approach to determining students who need additional instruction. Practical implications and future directions are discussed.  相似文献

A meta-analysis of the literature of cognitive behaviour therapy (CBT) with Arab adult populations experiencing anxiety, depression or post-traumatic stress disorder (PTSD) was conducted. Nine studies (n = 536) met the eligibility criteria. Three of the nine studies (33%) were randomised control trials using waitlist control groups. All studies (100%) reported a statistically significant reduction in psychological symptoms at post-treatment with large effect sizes for anxiety (effect size, 95% confidence interval) (1.44 [1.29, 1.59]), depression (1.26 [1.16, 1.35]) and PTSD (2.08 [1.94, 2.23]). Six out of the nine studies (67%) collated follow-up data and reported that reductions of psychological symptoms were maintained at follow-up. An average dropout rate of 26% indicated good overall acceptability. Five out of nine (55%) of the trials reported diagnostic remission rates and of those trials the mean remission rate was 31%). Five of the nine eligible studies (55%) delivered remotely via Internet or telephone were found to have similar effect sizes as face-to-face CBT. The current meta-analysis indicates the potential of CBT, delivered either face-to-face or via internet, as efficacious and acceptable interventions for the treatment of anxiety, depression and PTSD for Arab adult populations.  相似文献

This study compared the effects of a higher dose of cognitive behavioral therapy (CBT) for panic disorder versus CBT for panic disorder combined with "straying" to CBT for comorbid disorders in individuals with a principal diagnosis of panic disorder with or without agoraphobia. Sixty-five participants were randomly assigned to one of two treatment conditions, either CBT focused solely upon panic disorder and agoraphobia or CBT that simultaneously addressed panic disorder and agoraphobia and, to a lesser degree, the most severe comorbid condition. Results indicated a significant reduction in panic disorder severity and a decline in severity of comorbid diagnoses across both treatment conditions. However, individuals receiving CBT focused only on panic disorder were more likely to meet high end-state functioning at post-treatment, even in intent-to-treat analyses, and report zero panic attacks at the 1-year follow-up, although this effect was not retained in intent-to-treat analyses. At follow-up, CBT focused only on panic disorder yielded more substantial improvement in the most severe baseline comorbid condition, although not in intent-to-treat analyses, and a greater proportion of individuals in this treatment condition were rated as having no comorbid diagnoses, even in intent-to-treat analyses. These findings raise the possibility that remaining focused on CBT for panic disorder may be more beneficial for both principal and comorbid diagnoses than combining CBT for panic disorder with 'straying' to CBT for comorbid disorders.  相似文献

Presymptomatic testing for spinocerebellar ataxia type 2 (SCA2) in Cuba started five years ago. We have now investigated the psychological impact of test results on 150 individuals at 50% risk for SCA2. In a prospective study, psychological instruments were used to evaluate depression, anxiety and family functioning (1) before testing and (2) one year after disclosure of the test result. One year after, anxiety and depression levels decreased both in carriers and non-carriers, but anxiety decreased significantly more in carriers. Pathological levels of anxiety were seen mostly in members of dysfunctional families, but decreased more in them than in other consultands. Presymptomatic testing thus seems to have been especially beneficial for these testees, possibly due to a greater gain from the psychosocial support received. It would be pertinent to evaluate now the impact of other psychosocial variables and perform longer-term longitudinal studies.  相似文献

In a study with 112 third- and fourth-grade children, we measured the relative effectiveness of discovery learning and direct instruction at two points in the learning process: (a) during the initial acquisition of the basic cognitive objective (a procedure for designing and interpreting simple, unconfounded experiments) and (b) during the subsequent transfer and application of this basic skill to more diffuse and authentic reasoning associated with the evaluation of science-fair posters. We found not only that many more children learned from direct instruction than from discovery learning, but also that when asked to make broader, richer scientific judgments, the many children who learned about experimental design from direct instruction performed as well as those few children who discovered the method on their own. These results challenge predictions derived from the presumed superiority of discovery approaches in teaching young children basic procedures for early scientific investigations.  相似文献

Although available guidelines for familial cancer risk counseling clearly state the need to provide adequate psychosocial assessments and support, this feature of care is only available in part for individuals and families in oncogenetic counseling protocols in Portugal. The purpose of this study was to examine the psychosocial aspects of oncogenetic counseling provided by a sample of Portuguese genetics professionals. We sought to ascertain perceived need for the provision of psychosocial services and ways to enhance the psychosocial focus in service delivery. A qualitative study was designed; semi-structured focus groups and individual interviews were performed with 30 professionals from Portuguese healthcare institutions where oncogenetic counseling is offered. Findings suggest: current practice is aligned with the teaching model, with a mainly information-based focus; use of psychosocial counseling techniques and psychosocial support is limited throughout the genetic counseling timeline; there is a limited workforce of adequately trained psychosocial professionals, who are disadvantaged by structural and organizational constraints. These factors are considered to be serious barriers for psychosocial delivery. Development of multidisciplinary teams working in oncogenetics, and need for further counselling skills and training for genetics healthcare professionals were identified as priorities. Implications for practice and policy are discussed. Portuguese genetic counselors who have recently completed their training, may therefore contribute to enhanced psychosocial services delivery.  相似文献

We examined the effects of semantic priming of attention on two sequentially presented visuomotor tasks, traffic judgments and saccadic adaptation. Priming was accomplished with the scrambled sentence task: participants formed meaningful sentences from a list of words where a word denoting wide attention focus was involved. The results showed that semantic priming influenced positively saccade adaptation (its’ benefit increased) while it attenuated visuomotor performance in the traffic task (RT of hand movements increased). We found the effects of priming on both tasks’ performance to be comparable in young and older participants. It was suggested that semantic priming effect on visuomotor tasks depended on the cognitive resources which were needful as for the priming as for the primed task.  相似文献
