The neuropsychology of attention deficit/hyperactivity disorder (ADHD) has been extensively studied, with a general focus on global performance measures of executive function. In this study, we compared how global (i.e., endpoint) versus process (i.e., dynamic) measures of performance may help characterize children with and without ADHD using a design fluency task as a case study. The secondary goal was to compare the sensitivity of standard versus connectionist statistical models to group differences in cognitive data. Thirty-four children diagnosed with ADHD and 37 children without ADHD aged 8–11 years old were tested on the Five-Point Test. The continuous process measure of performance, indexed as the number of produced designs at each consecutive 1 minute interval during 5 minutes, was analyzed against the discrete process measure, that is, the number of designs between first and last intervals and the standard global performance measure of total number of produced designs. Results show that the continuous process measure distinguished the two groups better than the two other measures. The detailed observation of production patterns revealed a decreasing linear trajectory in children without ADHD that contrasts with the flat, but fluctuating productivity pattern of children with ADHD. With regards to the second goal, results show that the connectionist and standard methods are equally sensitive to group differences for the three types of measures. This illustrates the utility of quantitative process measures together with the connectionist method in neuropsychological research and suggests great potential for a dynamical approach to cognition. 相似文献

Background and Objectives: Stress is well known as a trigger of depressive reactions, fear, anxiety, and behavioral disorders. However, there are many gaps in the conceptualization and measurement of environmental stress. Results: Exciting developments in the neuroscience of stress have increasingly expanded our knowledge of mechanisms by which stress may affect emotional and behavioral adjustment. Ironically, environmental stress has often been a silent player in human studies of stress processes. There is a significant need for increased efforts to include environmental stress variables in models of internalizing and other disorders. Measurement and conceptualization issues are prominent, and this article makes the case for improved methods of measuring acute, chronic, and early life stress, and for additional conceptualization of the dynamically changing and bidirectional effects of stress on disorder over time. Conclusions: There is a critical need for greater focus on and better measurement of the environment and its impact on emotional and other disorders, with emphasis on developmentally informed hypotheses. Empirical findings and new perspectives may contribute enormously to our understanding of normal and abnormal outcomes, and also to the challenge of effective interventions to promote mental health and optimal functioning. 相似文献

This study investigated the psychometric properties of two subjective career success instruments within the South African context: Perceived Career Success (PCSS: Gattiker &; Larwood, 1986) and Life Success Measures Scale (LSMS: Parker &; Chusmir, 1992). Data were collected via a convenient sample of 708 South African Police Services (SAPS) personnel (females = 36.8%; Sotho language = 62.50%). Exploratory factor analysis (EFA) was conducted on both instruments, followed by confirmatory factor analyses (CFA). Both instruments showed acceptable construct validity and reliability of scores. 相似文献

Although drivers can adequately adjust their operating speed according to the road curvature, they show a lack of recognition regarding the pavement friction conditions. In this regard, inappropriate speed selection on Horizontal Curves (HCs) with reduced surface friction can lead to a remarkable rate of run-off-road, sideswipe, head-on, and rollover crashes, especially on rural highways. Aligned with the Connected Vehicle (CV) Pilot Program on Interstate-80 in Wyoming, this study scrutinizes how CV advisory/warning messages can enhance traffic safety on slippery HCs. To this aim, a roadway consists of two HCs with regular and slippery pavement conditions was designed in a high-fidelity driving simulator experiment. A total of 24 professional truck drivers were recruited to drive the simulated roadway under CV and non-CV environments. In the CV scenario, drivers were informed about the pavement conditions and the advisory speeds before entering HCs. In contrast, no messages were given to non-CV drivers. Truck drivers' behaviors in both scenarios were quantified using four Kinematic-based Surrogate Measures of Safety (K-SMoS), including deviation from the pathway, instantaneous acceleration, lateral speed, and steering angle. CVs’ trajectories were statistically compared to non-CVs in terms of the central tendency and dispersion using the Wilcoxon Signed-Rank Test (WSRT) and Median Absolute Deviation (MAD), respectively. The results of WSRT depicted, under the effect of CV advisory/warning messages and throughout the slippery HC, the central tendency of four K-SMoS could be shifted toward zero by 23% up to 99%. This shifting is associated with a significant safety enhancement that potentially can reduce the likelihood of curve-related crashes on slippery HCs. It was revealed that the variation in drivers’ behavior on the slippery HC could be minimized in the CV environment, where 54% up to 95% reduction in the dispersions of four K-SMoS were observed, leading to more certainty in drivers’ behavior. 相似文献

This paper presents the concerns of a client diagnosed with autism spectrum disorder about completing outcome measures. He was asked to complete CORE‐10 each time he attended a therapy session with the first author. This paper takes an epistemological position of co‐production, and written in response to the client's concerns, but this is limited by the client's wish and capacity to be involved in the writing up of this article. Implications of his experiences are drawn out for both clients with this diagnosis and more generally for all clients. Recommendations are made to recognise the limitations of measures and how to use outcome measures with more validity. 相似文献

With reports continually demonstrating increased demand and severity of student mental health needs, it is important to gain a fuller understanding of the impact on embedded student counselling services. The aims of this research were to identify (a) service similarities, (b) factors which impact on services, (c) characteristics of service users, and (d) the use of therapeutic technology (e.g. online self-help). An online survey was completed by 113 heads of UK student counselling services across Higher Education (HE), Further Education (FE), and Sixth Form Colleges (SFCs), to capture service data from the academic year 2013/14. Students predominantly received high-intensity support (e.g. counselling) and referrals increased over 3 years. Challenges to embedded counselling services and their implications for development are discussed. 相似文献

The aims of this study were to evaluate the effectiveness of a university counselling service in Northern Italy, to assess the sociodemographic and clinical characteristics of students who used counselling service, and to assess the psychological conditions of the students who ended the counselling after a 4 month follow-up period. The study involved 100 students, who filled out the General Health Questionnaire (GHQ-12), the Brief COPE Inventory, and the Symptom Checklist-90-Revised (SCL-90-R). The results showed that who received counselling were positively affected by this experience. The areas of benefit were psychological well-being, coping behaviours, ability to positively reframe problems and less sense of guilt. Additional studies are needed to identify which factors influence the outcomes of university counselling services in Italy. These studies would be important to evaluate the services rendered, upgrade the skills of counsellors and visualise priority areas of need. 相似文献

The present study represents one of the first comparisons of the long-term effectiveness of traditional cognitive behavior therapy (i.e., Beckian cognitive therapy; CT) and acceptance and commitment therapy (ACT). One hundred thirty-two anxious or depressed outpatients were randomly assigned to receive either CT or ACT, and were assessed at posttreatment (n = 90) and at 1.5-year (n = 91) follow-up. As previously reported, the two treatments were equivalently effective at posttreatment according to measures of depression, anxiety, overall (social/occupational/symptom-related) functioning, and quality of life. However, current results suggest that treatment gains were better maintained at follow-up in the CT condition. Clinical significance analyses revealed that, at follow-up, one-third more CT patients were in the clinically normative range in terms of depressive symptoms and more than twice as many CT patients were in the normative range in terms of functioning levels. The possible long-term advantage of CT relative to ACT in this population is discussed. 相似文献

It was hypothesized that, in natural group contexts, low‐status in‐group membership would be highly accessible, whereas membership to high‐status groups would not. Therefore, gender group membership was predicted to be more accessible for women than for men. It was further hypothesized that the high accessibility of gender group membership would lead to stronger self‐stereotyping for women than for men. To measure the accessibility of gender group membership, participants performed a Gender Self‐Categorization Implicit Association Test (Studies 1 and 2), measuring the strength of automatic associations between the self and the gender in‐group. Participants also performed a Self‐Stereotyping Implicit Association Test (Study 2), assessing the strength of automatic associations between the self and the stereotypical traits of the in‐group. As expected, implicit gender self‐categorization and implicit gender self‐stereotyping were stronger for women than for men. Importantly, implicit gender self‐categorization mediated the relation between gender and self‐stereotyping. Therefore, implicit gender self‐categorization was the mechanism underlying stronger implicit self‐stereotyping by women. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献
