The present study was designed to explore the effects of warned and unwarned demand transitions in vigilance on performance and self-reported stress. Twenty observers (10 women and 10 men) were assigned at random to each of six conditions resulting from the factorial combination of signal salience (high and low salience signals) and switching (no switch, switch with warning, and switch without warning). Performance metrics and self-reported stress state (Task Engagement, Distress, and Worry) were collected. While demand transitions did destabilize subsequent performance, increasing intra-individual variability, overall performance efficiency was uninfluenced by either switching or warning. Demand transitions, whether warned or not, increased self-reported distress. A dynamic model of performance stress may be necessary and research employing vigilance tasks in the future may be useful for developing this performance-stress model.  相似文献

The present study examined prevalence of lack of a close confidant in a medically underserved primary care sample, and evaluated demographic, medical, and psychological correlates of patients' deficits in close, personal contact. Adult patients (n = 413) reported on confidant status and symptoms of depression and anxiety. Sociodemographic and medical information were obtained through chart review. One-quarter of patients endorsed lack of a close confidant. Past month anxiety and depression symptoms, but not medical status, were associated with unmet socioemotional needs. Implications for primary healthcare interventions are discussed.  相似文献

Although continuing care is strongly related to positive treatment outcomes for substance use disorder (SUD), participation rates are low and few effective interventions are available. In a randomized clinical trial with 150 participants (97% men), 75 graduates of a residential Veterans Affairs Medical Center SUD program who received an aftercare contract, attendance prompts, and reinforcers (CPR) were compared to 75 graduates who received standard treatment (STX). Among CPR participants, 55% completed at least 3 months of aftercare, compared to 36% in STX. Similarly, CPR participants remained in treatment longer than those in STX (5.5 vs. 4.4 months). Additionally, CPR participants were more likely to be abstinent compared to STX (57% vs. 37%) after 1 year. The CPR intervention offers a practical means to improve adherence among individuals in SUD treatment.  相似文献

Hope is understood as being derived from a sense of well-being or a good-object feeling. From object relational and self-psychology perspectives, the author examines variations of hope, from hopelessness through idealized and malignant idealized hope to mature hope. Looking at idealized hope from both progressive and regressive positions, the author studies a case that has a dominant feature of regressive or malignant idealized hope. How group therapy plays a transformational role in addressing the issue of malignant idealized hope and in establishing a healthy sense of hope is developed.  相似文献

The present study estimated the unique contribution of self-efficacy to work-related performance controlling for personality (the Big 5 traits), intelligence or general mental ability, and job or task experience. Results, based on a meta-analysis of the relevant literatures, revealed that overall, across all studies and moderator conditions, the contribution of self-efficacy relative to purportedly more distal variables is relatively small. Within moderator categories, there were several cases in which self-efficacy made unique contributions to work-related performance. For example, self-efficacy predicted performance in jobs or tasks of low complexity but not those of medium or high complexity, and self-efficacy predicted performance for task but not job performance. Overall, results suggest that the predictive validity of self-efficacy is attenuated in the presence of individual differences, though this attenuation does depend on the context.  相似文献

This review seeks to examine whether the existing literature on child conduct problems (CP) supports the notion that certain CP risk factors vary in their importance across disadvantaged and better-off environments. Disadvantaged environments are represented by socioeconomic and/or neighborhood risk (SN risk) in this review. Three types of studies were reviewed: behavioral genetic studies that compare the importance of genetic and environmental influences on CP for youth from poor homes and/or disadvantaged communities versus youth from better-off contexts, studies that examine how SN risk and other CP risk factors interact, and studies that compare the antecedents for CP across levels of SN risk. Findings were inconsistent about the manner in which individual child risk factors interact with SN risk. However, familial risk factors were generally found to be of greater importance for youth from poor families and disadvantaged communities, particularly parental supervision. Most of the studies that indicated otherwise focused on physical discipline, or were limited to children from disadvantaged and extremely deprived environments. The findings suggest that in extremely deprived environments, familial influences are overwhelmed by the pervasiveness of other CP risk factors such as deviant peers. Implications for intervention and suggestions for future research are discussed.  相似文献

A differential reinforcement of low (DRL) rates procedure was implemented as a changing criterion design with positive punishment and response marking to reduce attention‐maintained behavior of screaming, profanity, and disruptive behaviors of three adolescent males. One participant was diagnosed with static encephalopathy and attention deficit hyperactivity disorder (ADHD) and severe mental retardation, the other two were diagnosed with Down syndrome, one with moderate mental retardation, and the other with severe mental retardation. Through response marking, a verbal warning was delivered immediately following the initial occurrence of a target behavior. A special token (positive punishment) was immediately delivered with a verbal cue and placed on a behavior board following the next occurrence of that behavior. Appropriate requests (hand‐raising) for attention was acknowledged and reinforced with verbal praise. The DRL procedure, combined with positive punishment and response marking, was successful in decreasing the frequency of targeted behaviors amongst all participants.

Researchers have yet to examine the impact of neighborhood disadvantage on early child behavior problems (BPs) longitudinally. We examined the impact of neighborhood disadvantage on overt BPs in a low-income, urban sample of 281 African American and European American boys followed longitudinally from toddlerhood to school entry. Measures included census data and maternal report of BPs, sociocultural factors, parental criminality, and maternal depressive symptomatology. After controlling for age 2 overt BPs, family selection variables, and residential instability, neighborhood effects on boys' behavior emerged, but only at age 6 and only at the extreme of neighborhood disadvantage (i.e., underclass). Findings suggest boys in underclass neighborhoods are at risk for overt BPs as they make the transition to elementary school.  相似文献

Two experiments were conducted to assess discrimination of picture requests for missing items among young children with developmental disabilities. In Experiment 1, three children were first taught to request one object when it was missing from a set of two related leisure items. In Experiment 2, two children were taught to request one object belonging to a set of three leisure items. In both studies the requesting response consisted of pointing to a photograph of the missing item. After acquisition of the initial request, discrimination of picture requests was assessed when the second item (Experiment 1) and second or third item (Experiment 2) was missing. Requests for the untrained items emerged in the presence of natural maintaining contingencies and in the absence of instructional prompts for all but the third child in Experiment 1. This child required continued intervention on the initial request. The results suggest that for some children a sequence of intervention and the programming of natural maintaining contingencies may prove effective in promoting the discrimination of picture requests for missing items among young children with developmental disabilities.  相似文献
