Although considerable evidence has linked sleep disturbance to symptoms of psychopathology, including repetitive negative thinking, few studies have examined how sleep disturbance may predict repetitive negative thinking over time. Further, no study to date has examined specific mechanisms that may account for this relationship. The present study sought to address these gaps in the literature by testing focusing and shifting attentional control as two potential mediators of the relationship between sleep disturbance and repetitive negative thinking over a 6-month period. A final sample of 445 unselected community participants completed measures of sleep disturbance and repetitive negative thinking at Time 1, measures of focusing and shifting attentional control 3 months later, and measures of repetitive negative thinking again 6 months later. Results revealed that focusing, but not shifting, attentional control mediated the relationship between sleep disturbance and repetitive negative thinking, specifically, worry, rumination, and obsessions. These findings provide preliminary evidence for focusing attentional control as a candidate mechanism that may explain the causal role of sleep disturbance in the development of repetitive negative thinking observed in various disorders. 相似文献

Visual inspection of single-subject data is the primary method for behavior analysts to interpret the effect of an independent variable on a dependent variable; however, there is no consensus on the most suitable method for teaching graph construction for single-subject designs. We systematically replicated and extended Tyner and Fienup (2015) using a repeated-measures between-subjects design to compare the effects of instructor-led, video-model, and no-instruction control tutorials on the graphing performance of 81 master's students with some reported Microsoft Excel experience. Our mixed-design analysis revealed a statistically significant main effect of pretest, tutorial, and posttest submissions for each tutorial group and a nonsignificant main effect of tutorial group. Tutorial group significantly interacted with submissions, suggesting that both instructor-led and video-model tutorials may be superior to providing graduate students with a written list of graphing conventions (i.e., control condition). Finally, training influenced performance on an untrained graph type (multielement) for all tutorial groups. 相似文献

In this study the associations between mothers' and fathers' differential parenting and children's oppositional and emotional problems were examined. A curvilinear relationship between differential parenting and children's outcomes was hypothesized, as well as the combined effect of mothers' and fathers' parenting. Data came from a community sample of 599 two-parent families with multiple children per family and were analyzed using a cross-classified multilevel model. Results showed that both family average parenting and differential parenting explained unique variance in children's outcomes. The curvilinear hypothesis was supported for oppositional behavior but not for emotional problems. The effects of mother and father positivity were found to be additive for both family average parenting and differential parenting, but for negativity there was evidence for multiplicative effects. 相似文献

We developed a multi-faceted prejudice habit-breaking intervention to produce long-term reductions in implicit race bias. The intervention is based on the premise that implicit bias is like a habit that can be broken through a combination of awareness of implicit bias, concern about the effects of that bias, and the application of strategies to reduce bias. In a 12-week longitudinal study, people who received the intervention showed dramatic reductions in implicit race bias. People who were concerned about discrimination or who reported using the strategies showed the greatest reductions. The intervention also led to increases in concern about discrimination and personal awareness of bias over the duration of the study. People in the control group showed none of the above effects. Our results raise the hope of reducing persistent and unintentional forms of discrimination that arise from implicit bias. 相似文献

It has been assumed (Lederman et al. 1990, Perception & Psychophysics) that a visual imagery process is involved in the haptic identification of raised-line drawings of common objects. The finding of significant correlations between visual imagery ability and performance on picture-naming tasks was taken as experimental evidence in support of this assumption. However, visual imagery measures came from self-report procedures, which can be unreliable. The present study therefore used an objective measure of visuospatial imagery abilities in sighted participants and compared three groups of high, medium and low visuospatial imagers on their accuracy and response times in identifying raised-line drawings by touch. Results revealed between-group differences on accuracy, with high visuospatial imagers outperforming low visuospatial imagers, but not on response times. These findings lend support to the view that visuospatial imagery plays a role in the identification of raised-line drawings by sighted adults. 相似文献

There are currently multiple explanations for mathematical learning disabilities (MLD). The present study focused on those assuming that MLD are due to a basic numerical deficit affecting the ability to represent and to manipulate number magnitude ( Butterworth, 1999 , 2005 ; A. J. Wilson & Dehaene, 2007 ) and/or to access that number magnitude representation from numerical symbols ( Rousselle & No?l, 2007 ). The present study provides an original contribution to this issue by testing MLD children (carefully selected on the basis of preserved abilities in other domains) on numerical estimation tasks with contrasting symbolic (Arabic numerals) and nonsymbolic (collection of dots) numbers used as input or output. MLD children performed consistently less accurately than control children on all the estimation tasks. However, MLD children were even weaker when the task involved the mapping between symbolic and nonsymbolic numbers than when the task required a mapping between two nonsymbolic numerical formats. Moreover, in the estimation of nonsymbolic numerosities, MLD children relied more than control children on perceptual cues such as the cumulative area of the dots. Finally, the task requiring a mapping from a nonsymbolic format to a symbolic format was the best predictor of MLD. In order to explain these present results, as well as those reported in the literature, we propose that the impoverished number magnitude representation of MLD children may arise from an initial mapping deficit between number symbols and that magnitude representation. 相似文献

Although anecdotal case accounts suggest that evidence concerning Antisocial Personality Disorder (APD), sociopathy and psychopathy is frequently introduced by the prosecution in capital murder trials, to date there has been no systematic research to determine the actual prevalence, role, or perceived impact of such evidence in these cases. Survey data collected from attendees at a national capital mitigation conference (n=41) indicated that prosecution evidence concerning APD was quite prevalent, with "sociopath" and "psychopath" labels being introduced less frequently. Evidence concerning these disorders, which were assessed primarily via DSM criteria and self-report personality inventories, was most often introduced by the prosecution in the sentencing phase to address a defendant's ostensible risk of future dangerousness and/or to rebut mitigating evidence-although it was also introduced frequently in the guilt/innocence phase of these trials to rebut mental health evidence offered by the defense. Survey respondents believed that evidence concerning APD, sociopathy, and psychopathy had a considerable impact on trial outcomes. Also, although defense objections were common, such evidence was rarely ruled to be inadmissible in these cases. 相似文献

To date, no empirically based inpatient intervention for individuals who have attempted suicide exists. We present an overview of a novel psychotherapeutic approach, Post-Admission Cognitive Therapy (PACT), currently under development and empirical testing for inpatients who have been admitted for a recent suicide attempt. PACT is adapted from an efficacious and brief outpatient cognitive therapy protocol (Brown, Henriques, Ratto, & Beck, 2002; Brown et al., 2005) for inpatient delivery to individuals with recent suicide attempts. Within a cognitive framework, attempting suicide is conceptualized as a maladaptive coping strategy that deserves immediate targeted clinical attention regardless of the patient's diagnosis. The primary aims of PACT are to reduce the likelihood of suicide attempt recurrence as well as decrease the severity of established psychological risk factors for suicide. The three phases of PACT involve (1) building a therapeutic alliance and developing a cognitive conceptualization based on the recent suicide attempt; (2) instilling hope, practicing effective coping strategies, and addressing problem-solving deficits; and (3) preventing relapse, constructing a safety plan, and promoting timely linkage with outpatient aftercare services. The efficacy of PACT as a targeted inpatient treatment package remains to be established. The cognitive behavioral components of PACT, as described here, are based on evidence-informed practices aimed at improving the quality of care provided to inpatients following a suicide attempt. 相似文献

Little in-depth research exists on subjective well-being (SWB) in the developing world, especially among the poor and extremely
poor. Biswas-Diener and Diener (Soc Indic Res 55:329–352, 2001) employed a study design in the slums of Calcutta, India to address this gap in SWB research. They found slightly negative
global SWB but slightly positive domain specific satisfaction in their sample. The current study employs the same paradigm
and investigates the SWB of female sex workers, city dump dwellers, and urban and rural poor in Nicaragua, Central America.
The current study was able to replicate the Biswas-Diener and Diener (Soc Indic Res 55:329–352, 2001) finding of slightly negative SWB for marginalized urban groups. In addition, an overall model for predicting SWB was constructed
using personality dispositions, objective income, social support, and social rootedness as predictors. Social support and
objective income were the only significant predictors in the model but more zero order relations existed. Additionally, this
study contrasted urban poor versus rural poor and found no significant SWB differences. 相似文献
