Poor attentional control leads to attentional biases that are implicated in psychological distress. Attention Training Technique (ATT) is an auditory intervention designed to strengthen attentional control. Research indicates that ATT alleviates anxiety and depressive symptoms. This study is a randomised control trial with repeated measures that tested if a lab-based, single-exposure of ATT strengthened attentional control. Forty-six nonclinical, high anxiety/worry participants received either ATT or a sham control intervention. Attentional control was assessed using the standard and a modified version of the colour-word Stroop task. The modified version incorporated tactile interference to increase perceptual load. A series of mixed effects models, simple contrasts, and z-tests were used to evaluate if cross-modal interference worsened, and whether ATT was beneficial to, attentional control. Tactile interference increased reaction times but, when Stroop interference was controlled for, this was only true on incongruent trials. The impact of ATT was greatest under high perceptual load. 相似文献

This paper suggests a conceptual framework for understanding the processes of help-seeking among survivors of intimate partner violence (IPV). A cognitive theory from general literature on help-seeking in “stigmatizing” situations suggests three relevant processes or stages of seeking help in the IPV context: defining the problem, deciding to seek help, and selecting a source of support. Individual, interpersonal, and sociocultural factors that influence decision-making at each of these stages are discussed and illustrated with case examples. 相似文献

Task switching: a PDP model 总被引:10,自引:0,他引:10
When subjects switch between a pair of stimulus-response tasks, reaction time is slower on trial N if a different task was performed on trial N - 1. We present a parallel distributed processing (PDP) model that simulates this effect when subjects switch between word reading and color naming in response to Stroop stimuli. Reaction time on "switch trials" can be slowed by an extended response selection process which results from (a) persisting, inappropriate states of activation and inhibition of task-controlling representations; and (b) associative learning, which allows stimuli to evoke tasks sets with which they have recently been associated (as proposed by Allport & Wylie, 2000). The model provides a good fit to a large body of empirical data, including findings which have been seen as problematic for this explanation of switch costs, and shows similar behavior when the parameters are set to random values, supporting Allport and Wylie's proposal. 相似文献

The underutilization of mental health services by Chinese individuals in the United States is concerning. In this study, we examined Chinese individuals’ help-seeking intentions utilizing the theory of planned behavior. Two hundred fifty-one participants were recruited for this study. The results revealed that help-seeking attitudes (β = 0.28, p < 0.001), perceived behavioral control (β = 0.21, p < 0.001), and subjective norms (β = 0.13, p < 0.001) were found to be significant predictors of help-seeking intentions. The implications of the results are discussed. 相似文献

In a cross-sectional study of 83 unmedicated boys, 6 to 16 years of age (M = 10.6, SD = 2.1), attending public (N = 48) and therapeutic schools for behaviorally disturbed children (N = 35), we examined relations of externalizing psychopathology to age-dependent change in performance on cognitive and motivational dimensions of impulse control assessed by laboratory tasks. When we controlled for internalizing symptoms and IQ or school achievement, all children showed improving competence with increasing age on both dimensions over the age range of the sample. Children with externalizing problems performed more poorly on both dimensions at all ages than children without such problems. Comparing age-dependent competence for the two groups, a model of convergent maturation in cognitive aspects of impulse control, and a model depicting a stable deficit in motivational aspects of impulse control in those children with externalizing behavior problems, relative to those without such problems, emerged. Studies of individual growth in impulse control, together with correlates of growth, are needed to validate these observations.Project on Human Development in Chicago Neighborhoods 相似文献

Learning to play musical instruments has been shown to enhance a wide variety of cognitive domains. The present study investigated the specific aspects of working memory (WM) that differed between adult musicians and non‐musicians. Twenty‐four musicians and 30 non‐musicians matched for age, gender, years of formal education, and verbal intelligence performed several WM tasks. A multivariate analysis of covariance, wherein family income was controlled, revealed that musicians outperformed non‐musicians in tasks related to visual–motor coordination, visual scanning ability, visual processing speed, and spatial memory. However, no significant differences were found in phonological and visual memory capacity. This study supports the view that music training is associated to specific (and not general) WM skills. 相似文献

The clinical differentiation of progressive supranuclear palsy from Parkinson's disease can be challenging, due to overlapping clinical features and a lack of diagnostic markers. Abnormalities in cognitive function form part of the clinical spectrums of these diseases and distinctive cognitive profiles may be helpful in differentiating these diseases in the diagnostic period. A comprehensive neuropsychological test battery was administered to 12 patients with clinically diagnosed progressive supranuclear palsy and 12 patients with Parkinson's disease matched for age and disease duration. Effect size (Cohen's d) was calculated for cognitive tests that were significantly different between groups. Patients with progressive supranuclear palsy performed significantly worse than those with Parkinson's disease on measures of processing speed, verbal fluency, planning, verbal abstract reasoning, verbal memory, and made more perseverative responses on a set shifting task. Measures of executive function, manual dexterity and processing speed were most diagnostically useful (Cohen's d > 2.0) in differentiating between progressive supranuclear palsy and Parkinson's disease. These findings suggest that more severe and prominent ‘frontal’ cognitive deficits in patients with progressive parkinsonism would be helpful in predicting progressive supranuclear palsy rather than Parkinson's disease and these findings may contribute to the development of diagnostic criteria. 相似文献

It has been proposed that executive functions develop in a hierarchical fashion, such that early, simple abilities seen already during the first year of life become increasingly coordinated with development, thereby enabling the emergence of more complex abilities. Although this hierarchical model has received support from empirical studies comparing executive function task performance across age groups, necessary support from longitudinal studies taking an individual differences perspective on development is missing. In addition, the model stresses the importance of attention in executive function development, but we do not know in what way attention contributes to the continued development once the earliest forms of simple functions have emerged. Using a longitudinal design, the present study investigated the relations between individual differences in simpler forms of executive functions as well as sustained attention at age 12 months and more complex executive functions at 24 and 36 months. The results indicated partial support for the hierarchical model, with infant inhibition being predictive of working memory in toddlerhood. In addition, at 12 months, sustained attention contributed to the development of toddler executive functions via the simple executive functions. This suggests that by this age, sustained attention has become an integrated part of early, simple executive functions. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
