Research suggests that attention is attracted to evolutionary threats (e.g., snakes) due to an evolved "fear-module" that automatically detects biological threats to survival. However, recent evidence indicates that non-evolutionary threats (e.g., guns) capture and hold attention as well, suggesting a more general "threat-relevance" mechanism that directs attentional resources toward any potential danger in the environment. The current research measured how selective attentional resources were influenced both by the type of threat (e.g., snake vs. gun) and by the context in which the threat was encountered. Participants were primed with either natural or human-made environments to assess how these contexts influence attention to evolutionary and non-evolutionary threats, as measured by a spatial-cueing task. The results indicate that whether biological or non-biological threats receive greater attentional processing is determined by the context in which they are encountered. 相似文献

In May 2011, the clinical ethics group of the Center for Ethics at Washington Hospital Center launched a 40-hour, three and one-half day Clinical Ethics Immersion Course. Created to address gaps in training in the practice of clinical ethics, the course is for those who now practice clinical ethics and for those who teach bioethics but who do not, or who rarely, have the opportunity to be in a clinical setting. "Immersion" refers to a high-intensity clinical ethics experience in a busy, urban, acute care hospital. During the Immersion Course, participants join clinical ethicists on working rounds in intensive care units and trauma service. Participants engage in a videotaped role-play conversation with an actor. Each simulated session reflects a practical, realistic clinical ethics case consultation scenario. Participants also review patients' charts, and have small group discussions on selected clinical ethics topics. As ethics consultation requests come into the center, Immersion Course participants accompany clinical ethicists on consultations. Specific to this pilot, because participants' evaluations and course faculty impressions were positive, the Center for Ethics will conduct the course twice each year. We look forward to improving the pilot and establishing the Immersion Course as one step towards addressing the gap in training opportunities in clinical ethics. 相似文献

Déjà vu is the striking sense that the present situation feels familiar, alongside the realization that it has to be new. According to the Gestalt familiarity hypothesis, déjà vu results when the configuration of elements within a scene maps onto a configuration previously seen, but the previous scene fails to come to mind. We examined this using virtual reality (VR) technology. When a new immersive VR scene resembled a previously-viewed scene in its configuration but people failed to recall the previously-viewed scene, familiarity ratings and reports of déjà vu were indeed higher than for completely novel scenes. People also exhibited the contrasting sense of newness and of familiarity that is characteristic of déjà vu. Familiarity ratings and déjà vu reports among scenes recognized as new increased with increasing feature-match of a scene to one stored in memory, suggesting that feature-matching can produce familiarity and déjà vu when recall fails. 相似文献

Abstract The current study examined specific emotional, behavioral, and cognitive variables that may distinguish obsessive-compulsive disorder (OCD) from generalized anxiety disorder (GAD), social phobia (SoP), and separation anxiety disorder (SAD) in youth. Youth with OCD (n=26) and other anxiety disorders (ADs; n=31), aged 7-12 years (56.1% males), and their parents participated. The study compared the two anxious groups on levels of emotional, behavioral, and cognitive functioning, as well as impairment associated with the disorder. Results indicated that in comparison to youth with GAD, SoP, or SAD, youth with OCD were found to have poorer emotion regulation skills, as well as greater oppositionality, cognitive problems/inattention, and parent impairment associated with the disorder. The findings suggest that there are unique characteristics of OCD that may differentiate this disorder from other ADs in youth. Potential clinical implications and directions for future research are discussed. 相似文献

Family-based interventions targeting parenting factors, such as parental monitoring and parent–child communication, have been
successful in reducing adolescent offenders’ substance use and delinquency. This pilot, exploratory study focuses on family
and parenting factors that may be relevant in reducing juvenile offenders’ substance use and sexual risk taking behavior,
and in particular examines the role of family emotional involvement and responsiveness in young offenders’ risk-taking behaviors.
Participants included 53 juvenile drug court offenders and their parents. Results indicate that poor parent–child communication
is associated with marijuana use and unprotected sexual activity for young offenders; however, family affective responsiveness
is also a significant unique predictor of unprotected sexual activity for these youth. Findings suggest that interventions
focused on improving parent–child communication may reduce both marijuana use and risky sexual behavior among court-involved
youth, but a specific intervention focused on improving parents and young offenders’ ability to connect with and respond to
one another emotionally may provide a novel means of reducing unprotected sexual risk behaviors. 相似文献

The purpose of this study was to examine the effectiveness of evidence-based recruitment and retention strategies for a longitudinal, family-based HIV prevention intervention study targeting adolescents in psychiatric care by (1) determining consent rate (recruitment), rate of participation at the first intervention session (retention), and follow-up attendance rate (retention); and (2) examining socio-demographic factors, family-level processes, sexual risk-related indices, and intervention factors (i.e., treatment arm) associated with study retention. Only one-third of the families contacted ultimately enrolled in the study. 81% of those enrolled participated in the workshop and 72% attended the booster sessions with no significant differences between families on any variable based on attendance. Retention over 1?year was 85% and did not differ by treatment arm. Strategies employed were successful at retaining families once they were enrolled. Findings highlight barriers to enrollment for adolescents in psychiatric care and suggest that it may be critical to integrate HIV prevention programs within community-based mental health services in order to counteract recruitment challenges. 相似文献

To counter response distortions associated with the use of rating scales (a.k.a. Likert scales), items can be presented in a comparative fashion, so that respondents are asked to rank the items within blocks (forced-choice format). However, classical scoring procedures for these forced-choice designs lead to ipsative data, which presents psychometric challenges that are well described in the literature. Recently, Brown and Maydeu-Olivares (Educational and Psychological Measurement 71: 460–502, 2011a) introduced a model based on Thurstone’s law of comparative judgment, which overcomes the problems of ipsative data. Here, we provide a step-by-step tutorial for coding forced-choice responses, specifying a Thurstonian item response theory model that is appropriate for the design used, assessing the model’s fit, and scoring individuals on psychological attributes. Estimation and scoring is performed using Mplus, and a very straightforward Excel macro is provided that writes full Mplus input files for any forced-choice design. Armed with these tools, using a forced-choice design is now as easy as using ratings. 相似文献

This is the second of two articles that describe the development and evaluation of three component-specific instructional systems for improving critical reading skills. The skill components that were the focus of training have been shown in prior research to represent particular sources of processing difficulty for young adult, poor readers and, based on a model of component interaction, were predicted to have a potentially strong impact on the performance of other component processes. Part 1 presented the evaluation of SPEED, a system designed to develop automaticity in the ability to perceptually encode multiletter units that appear in words. Part 2 describes the evaluation of the RACER and SKI JUMP systems, which focus respectively on developing automaticity in phonological decoding of orthographic information in words and the use of context frames in retrieving and integrating word meanings. In both the RACER and SKI JUMP training studies, all subjects achieved highly accurate and efficient levels of performance in the skill that was the focus of training. Furthermore, SKI JUMP training had an impact on word analysis components and on a measure of inferential comprehension. An analysis of the patterns of transfer of skills acquired in training is presented, and conditions for optimizing skill integration are discussed. 相似文献
