Research on affect as a group-level phenomenon has shown that over time, individual members within a group become highly similar in their affect (i.e., members experience and display similar emotions and moods), and often become similar enough that the aggregation of individuals’ affect can meaningfully represent the “affective tone” of the group. It is generally assumed that a more positive affective tone will lead to better team performance. We challenge the conclusion that positive affective tone is always good for team performance, suggesting that the relationship between positive affective tone and team performance is subject to moderating influences. Across two studies, we demonstrate that the self-reported collective emotional skills of team members play a crucial role in determining whether positive affective tone is beneficial or detrimental to team performance. Implications for theory and practice are discussed. 相似文献

Is Passive Syntax Semantically Constrained? Evidence From Adult Grammaticality Judgment and Comprehension Studies 下载免费PDF全文

To explain the phenomenon that certain English verbs resist passivization (e.g., *£5 was cost by the book), Pinker (1989) proposed a semantic constraint on the passive in the adult grammar: The greater the extent to which a verb denotes an action where a patient is affected or acted upon, the greater the extent to which it is compatible with the passive. However, a number of comprehension and production priming studies have cast doubt upon this claim, finding no difference between highly affecting agent‐patient/theme‐experiencer passives (e.g., Wendy was kicked/frightened by Bob) and non‐actional experiencer theme passives (e.g., Wendy was heard by Bob). The present study provides evidence that a semantic constraint is psychologically real, and is readily observed when more fine‐grained independent and dependent measures are used (i.e., participant ratings of verb semantics, graded grammaticality judgments, and reaction time in a forced‐choice picture‐matching comprehension task). We conclude that a semantic constraint on the passive must be incorporated into accounts of the adult grammar. 相似文献

Empirical research is needed to verify that the DSM-5 proposed diagnostic criteria for non-suicidal self-injury (NSSI) disorder provide a valid and clinically meaningful symptom set. The current study used data-driven methods to examine the diagnostic validity of the frequency and recency thresholds (i.e., Criterion A) for NSSI disorder. Data were collected from a random sample (n = 2206) of undergraduates. Participants completed counter-balanced questionnaires assessing the frequency, recency, and functions of NSSI, psychopathology symptoms, and indicators of distress and functional impairment. Discriminant functional analyses identified a significant differentiation for frequency between 10 or more acts of NSSI and 1–9 acts. Groups were also differentiated with a split on recency between less than 12-months ago and more than 12-months ago. After re-grouping the sample into categories based on the new frequency and 12-month recency threshold, the 10+ NSSI group reported significantly more functions for NSSI, including higher scores on affect regulation, self-punishment, and sensation seeking, than the subthreshold NSSI group. The 10+ NSSI group also reported significantly worse psychopathology, greater distress, and more impairment than both the subthreshold group and controls (no NSSI history). These findings indicate the current DSM-5 diagnostic criteria for NSSI disorder may be too liberal, and offer support for increasing the frequency thresholds for the diagnosis to ensure clinical validity and utility. 相似文献

Organization, Time Management, and Planning (OTP) problems are a key mechanism of academic failure for adolescents with ADHD. Parents may be well positioned to promote remediation of these deficits; yet, almost nothing is known about OTP management behaviors among parents of middle and high school students with ADHD. In a sample of 299 well-diagnosed adolescents with ADHD, a measure of parental OTP management was psychometrically validated. Latent Class Analysis was conducted to detect distinct patterns of parental OTP management and yielded four unique classes: Parental Control (18.7 %), Parent-Teen Collaboration (20.4 %), Homework Assistance (20.4 %), and Uninvolved (40.5 %). Logistic Regression analyses indicated that maladaptive parental OTP strategies were related to higher levels of parent and adolescent psychopathology. Parental OTP management did not relate to current adolescent OTP skills or GPA, indicating that parents did not select OTP management strategies in immediate response to adolescent functioning. Implications for parent-directed intervention are discussed. 相似文献

The Behavior Rating Inventory of Executive Functioning (BRIEF) is a parent report measure designed to assess executive skills in everyday life. The present study employed a confirmatory factor analysis (CFA) to evaluate three alternative models of the factor structure of the BRIEF. Given the executive functioning difficulties that commonly co-occur with attention-deficit/hyperactivity disorder (ADHD), the participants included 181 children and adolescents with a diagnosis of ADHD. The results indicated that an oblique two-factor model, in which the Monitor subscale loaded on both factors (i.e., Behavioral Regulation, Metacognition) and measurement errors for the Monitor and Inhibit subscales were allowed to correlate, provided an acceptable goodness-of-fit to the data. This two-factor model is consistent with previous research indicating that the Monitor subscale reflects two dimensions (i.e., monitoring of task-related activities and monitoring of personal behavioral activities) and thus loads on multiple factors. These findings support the clinical relevance of the BRIEF in children with ADHD, as well as the multidimensional nature of executive functioning. 相似文献

Posttraumatic stress disorder (PTSD) is associated with executive functioning deficits, including disruptions in working memory (WM). Recent studies suggest that attention training reduces PTSD symptomatology, but the underlying neural mechanisms are unknown. We used high-density magnetoencephalography (MEG) to evaluate whether attention training modulates brain regions serving WM processing in PTSD. Fourteen veterans with PTSD completed a WM task during a 306-sensor MEG recording before and after 8 sessions of attention training treatment. A matched comparison sample of 12 combat-exposed veterans without PTSD completed the same WM task during a single MEG session. To identify the spatiotemporal dynamics, each group’s data were transformed into the time-frequency domain, and significant oscillatory brain responses were imaged using a beamforming approach. All participants exhibited activity in left hemispheric language areas consistent with a verbal WM task. Additionally, veterans with PTSD and combat-exposed healthy controls each exhibited oscillatory responses in right hemispheric homologue regions (e.g., right Broca’s area); however, these responses were in opposite directions. Group differences in oscillatory activity emerged in the theta band (4–8 Hz) during encoding and in the alpha band (9–12 Hz) during maintenance and were significant in right prefrontal and right supramarginal and inferior parietal regions. Importantly, following attention training, these significant group differences were reduced or eliminated. This study provides initial evidence that attention training improves aberrant neural activity in brain networks serving WM processing. 相似文献

Although cognitions are central to the conceptualization and treatment of anxiety in typically developing (TD) youth, there is scant research investigating automatic thoughts and their relationship with anxiety in youth with autism spectrum disorder (ASD). We sought to examine the types of automatic thoughts experienced by youth with ASD and co-occurring anxiety as well as the predictive relationship of anxiety to different types of automatic thoughts in 97 children, ages 8-14 years. We also explored the relationship of automatic thoughts and intolerance of uncertainty. Consistent with prior data, there was a strong relationship between anxiety and automatic thoughts pertaining to social and physical threat. Anxiety and IU were independently associated with thoughts pertaining to personal failure which raises the hypothesis that personal failure may serve as a common pathway between anxiety, IU, and depression in ASD youth. These findings highlight the importance of assessing and treating negative cognitions in youth with ASD and anxiety. 相似文献

Previous research has identified factors related to outcome in child anxiety treatment and parent training programs for child behavior problems. However, it is unclear what factors predict outcomes in interventions delivered online to parents of young children at risk of anxiety. This study investigated predictors of child anxiety outcomes among 433 families with young children (3–6 years) who participated in a randomized controlled trial of Cool Little Kids Online, an eight-module early intervention program for child anxiety based on cognitive-behavioral therapy (CBT). Potential predictors included baseline demographic factors, child and parent mental health factors, and indicators of program use, including number of online modules completed and frequency of homework practice. Results showed that only access to a printer moderated intervention effectiveness. Printer access predicted lower child anxiety in the Cool Little Kids Online group, but had no effect on outcomes in the wait-list group. In both groups, higher levels of child anxiety symptoms, child-inhibited temperament, and poorer parent mental health at baseline predicted higher levels of child anxiety symptoms at 6-month follow-up. The amount of online program use was not related to improvements in child anxiety symptoms. However, parents who reported practicing the program skills more frequently showed greater reductions in child anxiety, and access to a printer was related to frequency of program skills practice. These findings provide empirical support for the important role of skills practice in online CBT interventions, and suggest that practicing program skills may be more important than completing the online modules. 相似文献

With the signing of H.R. 1256, the Family Smoking Prevention and Tobacco Control Act, the United States Food and Drug Administration (FDA) gained regulatory authority over the tobacco industry. A notable clause in this Act permits the FDA to regulate nicotine yields. However, they cannot completely remove this addictive constituent from tobacco products. This restriction has prompted the FDA to seek research on the threshold dose of nicotine that does not support dependence. This idea of threshold dose has led to an interesting reframing of scientific questions. For example, some researchers studying nicotine from this regulatory perspective translated the notion of an addiction threshold to a construct thought to play a role in addiction but which can be more readily operationalized. Examples include reinforcement threshold, discrimination threshold, and reinforcer‐enhancement threshold. In this Perspective Paper, we highlight the importance of behavioral pharmacology and, specifically, the experimental analysis of behavior to help establish a scientific basis for policy decisions regarding nicotine yields. Recent research, including exemplars provided herein, note vast individual differences in the effects of nicotine at a known dose. Unfortunately, the behavioral and biological factors that contribute to such individual variations remain to be understood. We believe that behavior analysts are uniquely well‐positioned to contribute to this understanding. 相似文献

This study used meta-analytic methods to compare the functioning of parents of children with cancer to parents of physically healthy children or normative samples. A meta-analysis using fixed effects, weighted least squares methods was conducted on 29 studies examining psychological distress and marital and family functioning among parents of children with cancer. Mothers and fathers of children newly diagnosed with cancer reported significantly greater distress than comparison samples. Mothers reported greater distress than fathers up to 12 months postdiagnosis. Mothers of children with cancer reported higher levels of family conflict than mothers of healthy children. Findings suggest that pediatric cancer impacts parents' perceptions of self- and family functioning, especially within the 1st year following diagnosis. 相似文献
