The present study investigates sleep, mood, and the proposed bidirectional relationship between the two in psychiatric disorders. Participants with interepisode bipolar disorder (n = 49), insomnia (n = 34), and no psychiatric history (n = 52) completed seven consecutive days of sleep diaries and mood measures. The interepisode bipolar and insomnia participants exhibited greater sleep disturbance than the healthy control individuals. Negative mood was equally heightened in both interepisode bipolar disorder and insomnia, and there were no differences between the three groups in positive mood. Total wake time was associated with next morning negative mood in bipolar disorder, whereas evening negative mood was associated with subsequent total wake time in both bipolar disorder and insomnia. Additionally, positive mood was associated with subsequent total wake time for the insomnia group. Results support the theory that disruptions in nighttime sleep and daytime mood may be mutually maintaining and suggest the potential importance of transdiagnostic or universal processes.  相似文献

Recent studies of adults have found evidence for consolidation effects in the acquisition of novel words, but little is known about whether such effects are found developmentally. In two experiments, we familiarized children with novel nonwords (e.g., biscal) and tested their recognition and recall of these items. In Experiment 1, 7-year-olds were then retested on either the same day or the following day to examine changes in performance after a short delay compared with a longer delay that included sleep. Experiment 2 used two age groups (7- and 12-year-olds), with all participants being retested 24h later. The 12-year-olds accurately recognized the novel nonwords immediately after exposure, as did the 7-year-olds in Experiment 2 (but not in Experiment 1), suggesting generally good initial rates of learning. Experiment 1 revealed improved recognition of the novel nonwords after both short (3- to 4-h) and longer (24-h) delays. In contrast, recall was initially poor but showed improvements only when children were retested 24h later, not after a 3- to 4-h delay. Similar improvements were observed in both age groups despite better overall performance in 12-year-olds. We argue that children, like adults, exhibit offline consolidation effects on the formation of novel phonological representations.  相似文献

With a multisource sample comprising 1,150 employees and 230 supervisors, we investigate the effect of leader goal orientation on leader's perceptions of unit performance. We propose that a leader's goal orientation indirectly impacts performance perceptions via the shared achievement goal adopted within the unit (i.e., unit goal orientation). Further, we hypothesize that the presence and impact of unit goal orientation depend on the work unit structure. We find general support for this moderated mediation model, with the strongest evidence being associated with the learning and prove dimensions of goal orientation.

Humans are empathic animals. We automatically match other people's motor responses, allowing us to get “under the skin” of other people. Although this perception–action-coupling—a form of motor resonance—occurs spontaneously, this happens less readily with the outgroup (vs. the ingroup) and for those high (vs. low) in prejudice. Thus, prejudice diminishes our tendency to resonate with the outgroup. Here we suggest that the reverse is also possible—that resonating with the actions of an outgroup member can reduce prejudice. We predict, in other words, that explicitly mimicking the outgroup can reduce prejudice. Participants watched a 140-second video depicting actors repeatedly reaching for and drinking from a glass of water. They passively watched a video with Black actors; watched the video and mimicked the Black actors; or watched and mimicked a video with actors from their ingroup. Participants then completed the Affect Misattribution Procedure (Payne, Cheng, Govorun, & Stewart, 2005), a measure of implicit anti-Black prejudice, and an explicit symbolic racism measure. Results indicate that the outgroup-mimicry group had similar implicit preference for Blacks and Whites, unlike the other two groups, which preferred Whites over Blacks. The outgroup-mimicry group also reported less explicit racism towards Blacks than the ingroup-mimicry group, but no less than the ingroup-observation group. Mimicking specific outgroup members, therefore, reduces implicit, and possibly explicit, bias against the outgroup more generally.  相似文献

Dishonest behavior can have various psychological outcomes. We examine whether one consequence could be the forgetting of moral rules. In 4 experiments, participants were given the opportunity to behave dishonestly, and thus earn undeserved money, by over-reporting their performance on an ability-based task. Before the task, they were exposed to moral rules (i.e., an honor code). Those who cheated were more likely to forget the moral rules after behaving dishonestly, even though they were equally likely to remember morally irrelevant information (Experiment 1). Furthermore, people showed moral forgetting only after cheating could be enacted but not before cheating (Experiment 2), despite monetary incentives to recall the rules accurately (Experiment 3). Finally, moral forgetting appears to result from decreased access to moral rules after cheating (Experiment 4).  相似文献

Evidence-based methods for assisting consumers, such as counties, in successfully implementing practices are lacking in the field of implementation science. To fill this gap, the Community Development Teams (CDT) approach was developed to assist counties in developing peer networks focused on problem-solving and resource sharing to enhance their possibility of successful implementation. The CDT is an interactive, solution-focused approach that shares many elements of the Interactive Systems Framework (ISF) for Dissemination and Implementation. An ongoing randomized implementation trial of Multidimensional Treatment Foster Care (MTFC) was designed to test the hypothesis that such interactive implementation methods are more successful at helping counties achieve successful and sustainable MTFC programs than standard individualized implementation methods. Using the Stages of Implementation Completion measure, developed for this study, the potential benefit of these interactive methods is examined at different stages of the implementation process ranging from initial engagement to program competency.  相似文献

Socially disinhibited or indiscriminate behavior (IB) has traditionally been investigated using caregiver reports. More recently, an observational measure based on the Strange Situation Procedure (M. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978), the Rating of Infant and Stranger Engagement (RISE; C. Riley, A. Atlas‐Corbett, & K. Lyons‐Ruth, 2005), was validated in home‐reared at‐risk children. The present study aimed to validate the RISE in an institutionally reared sample using the caregiver report, to assess whether IB assessed with the RISE was elevated among the institutionalized children, and to explore potential risk factors associated with IB. The study was conducted among 74 institutionalized toddlers aged 11 to 30 months. Sociodemographic questionnaires were used to assess pre‐admission experiences, and aspects of institutional placement were coded from the children's files in the institution and staff's report. Institutionalized children displayed high frequencies of IB as assessed on the RISE, and this instrument was validated against caregiver report. Pre‐admission experiences of the institutionalized children in their biological families—namely, prenatal risk and maternal emotional neglect risk—predicted IB. Results suggest that the RISE is adequate to use among institutionally reared toddlers and point to aspects of the early familial environment that may be implicated in IB.  相似文献

Word use has been shown to reflect various psychological processes and psychological change. This study examines the self-view in personality disorders (PDs) and its change over the course of therapy using the Linguistic Inquiry and Word Count analysis procedure. A sample of 299 participants with PDs and 108 community control participants wrote short essays about their lives. Patients repeated the assignment three times over two years and completed assessments of PD-pathology, general psychopathology, PD-beliefs, and quality of life. Results show that as hypothesized the use of words in the 1st Person Singular Pronouns, Negative Emotion, Causation, Past and Future Tense Verbs categories significantly declines over the course of treatment, while the use of Present Tense Verbs and Positive Emotion increases. These categories tend to distinguish patients from non-patients prior to treatment. We also found 12 additional word categories changing over time, including Word Count and Negations. Change in word use statistically predicts better treatment outcome on all outcome measures (p < .001). Reductions in the use of Negative Emotion Words and Negations are the strongest predictors of outcome. The non-hypothesized role of Negations was explored and seemed to reflect that PD-patients miss a lot in their lives. Reduction of what they miss seems central to recovery. This issue seems relatively neglected in theoretical and treatment models of PDs. An increased focus on what patients miss in their lives might improve our understanding and treatment of PDs. In sum, Negative Emotion and Negation word categories appear to reflect key treatment targets.  相似文献

The data obtained from one‐way independent groups designs is typically non‐normal in form and rarely equally variable across treatment populations (i.e. population variances are heterogeneous). Consequently, the classical test statistic that is used to assess statistical significance (i.e. the analysis of variance F test) typically provides invalid results (e.g. too many Type I errors, reduced power). For this reason, there has been considerable interest in finding a test statistic that is appropriate under conditions of non‐normality and variance heterogeneity. Previously recommended procedures for analysing such data include the James test, the Welch test applied either to the usual least squares estimators of central tendency and variability, or the Welch test with robust estimators (i.e. trimmed means and Winsorized variances). A new statistic proposed by Krishnamoorthy, Lu, and Mathew, intended to deal with heterogeneous variances, though not non‐normality, uses a parametric bootstrap procedure. In their investigation of the parametric bootstrap test, the authors examined its operating characteristics under limited conditions and did not compare it to the Welch test based on robust estimators. Thus, we investigated how the parametric bootstrap procedure and a modified parametric bootstrap procedure based on trimmed means perform relative to previously recommended procedures when data are non‐normal and heterogeneous. The results indicated that the tests based on trimmed means offer the best Type I error control and power when variances are unequal and at least some of the distribution shapes are non‐normal.  相似文献
