The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal hypothesized differences between the subtypes in specific neurocognitive systems (anterior vs. posterior attentional systems) and processes (arousal vs. activation). Thirty-four CB and 26 PI children meeting full DSM-IV criteria for subtype both in school and at home, without confounding reading disability or emotional disorder, were enrolled along with 20 typically developing children. Neurocognitive functions measured included attention, inhibitory control, working memory, learning, and executive functions. Tasks included the Stroop, Wisconsin Card Sorting Test, Continuous Performance Test (CPT). Buschke Selective Reminding Test, ad the Tower of London (TOL), as well as instruments developed by Posner and Sternberg, and tasks assessing the impact on reaction time of [corrected] varying preparatory intervals and stimulus/response complexity. After co-varying for IQ, subtypes differed primarily on measures of impulsivity during tests of vigilance (CPT) and executive function (TOL), with the CB group showing greater impulsivity than both other groups. In addition, the PI group showed worse performance than CB and control groups on the WISC-III Processing Speed Index. Whether analyzed with or without an IQ co-variate, there was no support in the data for hypothesized differences between subtypes in functioning of the anterior vs. posterior attentional systems, nor in involvement of arousal vs. activation processes. The results indicate that the PI and CB subtypes are best differentiated by ratings, observations and tests of cognitive tempo and behavioral impulsivity. Neuropsychological methods have yet to identify critical neuropsychological [corrected] substrates of these differences. 相似文献

The social neuroscience of child and adolescent depression is inherently multidisciplinary. Depressive disorders beginning early in life can have serious developmental and functional consequences. Psychopathology research has described depression's defining clinical and contextual features, and intervention research has characterized its response to treatment and prevention programs. Neuroendocrine, electrophysiological, and neuroimaging studies have identified core neurobiological aspects of early-onset mood disorders. These areas are reviewed using a developmental social neuroscience perspective for integrating disparate observations. The paper introduces a dynamic adaptive systems framework, and it discusses hedonic capacity, stress sensitivity, ruminative self-focus, and attentional impairments as fundamental components of mood disorders. 相似文献

To understand the ways that EMS providers cope with pediatric death in an out-of-hospital setting, eight focus groups were conducted with 98 urban, rural, and suburban EMS providers. Sixty-eight of the participants also completed a short questionnaire about a specific event. In both the focus groups and questionnaire, participants were asked how they individually coped with the death, how they coped as a team, and what coping strategies were most and least helpful. Specific coping strategies were found to be helpful to EMS providers, and could be classified as Solve, Solace, Dismiss, and Escape based on whether they approached or avoided the problem or the emotion. 相似文献

This study aimed to validate the Life Role Salience Scale (LRSS) in a South African context. Respondents were 300 working adults (72.3% = women; 57.9% = non-white; mean age = 35.12 years, SD = 10.25 years; mostly from the finance sector = 35.6%). Confirmatory factor and exploratory factor analyses were conducted to determine the LRSS’s factor structure and reliability of scores from the scale for the South African sample. Results yielded five factors emerging from the analyses: Homecare role reward value and homecare role commitment; marital role reward value and marital role commitment; occupational role commitment; occupational role value reward; and parental role reward value. The reliability of scores from the LRSS ranged from 0.79 (parental role reward value) to 0.95 (homecare role reward value and homecare role commitment). The LRSS shows validity for research use in South Africa. 相似文献

The authors describe an intensive outpatient dialectical behavior therapy (DBT) program for multidiagnostic clients with eating disorders who had not responded adequately to standard, empirically supported treatments for eating disorders. The program integrates DBT with empirically supported cognitive behavior therapy approaches that are well established for the treatment of eating disorders. Attention is given to inclusion and exclusion criteria, how the program differs from standard treatments for eating disorders, and the application of specific DBT treatment components for multidiagnostic clients with eating disorders. 相似文献

This research investigates the effects of sales-service ambidexterity on salesperson role perceptions, behaviors, and customer satisfaction. Using a business-to-business, salesperson-customer sample, we build and test a model which highlights both the positive and negative consequences of this simultaneous goal pursuit. Specifically, while sales-service ambidexterity positively impacts adaptive selling behaviors, it also increases perceptions of role conflict among salespeople. Customer demandingness moderates these relationships. Taken together, the results provide insights for firms on how to manage their sales force to optimize both sales and service outcomes based on characteristics of their salespeople and customers. 相似文献

The paper discusses Bernard Bolzano’s epistemological approach to believing and knowing with regard to the epistemic requirements
of an axiomatic model of science. It relates Bolzano’s notions of believing, knowing and evaluation to notions of infallibility,
immediacy and foundational truth. If axiomatic systems require their foundational truths to be infallibly known, this knowledge
involves both evaluation of the infallibility of the asserted truth and evaluation of its being foundational. The twofold
attempt to examine one’s assertions and to do so by searching for the objective grounds of the truths asserted lies at the
heart of Bolzano’s notion of knowledge. However, the explanatory task of searching for grounds requires methods that cannot
warrant infallibility. Hence, its constitutive role in a conception of knowledge seems to imply the fallibility of such knowledge.
I argue that the explanatory task contained in Bolzanian knowing involves a high degree of epistemic virtues, and that it
is only through some salient virtue that the credit of infallibility can distinguish Bolzanian knowing from a high degree
of Bolzanian believing. 相似文献

Recent research has suggested that the six‐dimensional personality model, and especially the dimension Honesty–Humility/Integrity, adds incremental validity to the prediction of important criteria. We expected both this dimension and the dimension Conscientiousness to explain incremental variance in two academic criteria, namely grade point average (GPA) and counterproductive academic behaviour (CAB). In addition, we expected the more specific, so‐called narrow traits of Conscientiousness and Honesty–Humility/Integrity to be stronger predictors of academic criteria than the broad traits. To test these expectations, two studies were conducted using the HEXACO Personality Inventory Revised (HEXACO‐PI‐R) and the Multicultural Personality Test—Big Six (MPT‐BS). The results confirmed our expectations and suggest that academic criteria may be predicted with greater accuracy by focusing on the narrow traits of Conscientiousness and Honesty–Humility/Integrity.

ABSTRACT Recent research has demonstrated that patients with Alzheimer's disease (AD) show deficits in semantic processing when compared to cognitively healthy individuals. This difference is thought to be attributed to losses in higher cortical systems that are predominantly associated with executive functioning. The first aim of the study will be to determine if differences in semantic clustering can accurately differentiate patients with amnestic mild cognitive impairment (aMCI) from cognitively normal (CN) individuals. The second aim will be to determine the extent to which semantic processing might be associated with executive functions. Data from 202 (134 CN, 68 aMCI) participants were analyzed to quantify differences in semantic clustering ratios on the HVLT-R. Study participants ages ranged from 51 to 87 with education ranging from 6 to 20 years. ANCOVA revealed statistically significant differences on semantic clustering ratios (p < .001). Moderate correlations between semantic clustering Category Fluency Test (r = .45) were also found. Statistically significant group differences were also present on Trails-B and WAIS-R Digit Symbol performance (p < .001). Overall, these data indicate that deficits in semantic clustering are present in aMCI patients. 相似文献

According to interaction ist theory, responses of professionals to potential deviance will vary by characteristics of the event, characteristics of the biography and training of the observer, and characteristics of the organization in which the process occurs. Hypotheses concerning recognition and reporting of child abuse were tested using a factorial survey design. A probability sample of nurses (N = 1,038) judged vignettes, in which case characteristic variables were systematically manipulated, and responded to a questionnaire on their background, professional work, and organization. Case characteristics involving type and level of seriousness of abuse, perpetrator status, and perpetrator psychology had the greatest effects on the average recognition and reporting scores, as shown in the analysis using ordinary least squares regression. Contrary to interaction ist predictions, only a small additional amount of the variance was accounted for when the nurses’ characteristics and organizational characteristics were added to the equation. Implications of the findings for further research and for social policy and practice concerning child abuse are discussed. 相似文献
