proposed an intriguing and detailed evolutionary theory of dreams which stipulates that the biological function of dreaming is to simulate threatening events and to rehearse threat avoidance behaviors. The goal of the present study was to test this theory using a sample of 212 recurrent dreams that was scored using a slightly expanded version of the DreamThreat rating scale. Six of the eight hypotheses tested were supported. Among the positive findings, 66% of the recurrent dream reports contained one or more threats, the threats tended to be dangerous and aimed at the dreamer, and when facing a threat, the dreamer tended to take defensive or evasive actions that were possible and reasonable. However, less than 15% of the recurrent dreams depicted realistic and probable situations critical for one's physical survival or reproductive success and the dreamer rarely succeeded in fleeing the threat despite important and appropriate efforts. The findings thus provide mixed support for the threat simulation theory. 相似文献

This meta-analytic review summarizes obesity prevention programs and their effects and investigates participant, intervention, delivery, and design features associated with larger effects. A literature search identified 64 prevention programs seeking to produce weight gain prevention effects, of which 21% produced significant prevention effects that were typically pre- to post effects. Larger effects emerged for programs that targeted children and adolescents (vs. preadolescents) and females, programs that were relatively brief, programs that solely targeted weight control versus other health behaviors (e.g., smoking), programs evaluated in pilot trials, and programs wherein participants must have self-selected into the intervention. Other factors, including mandated improvements in diet and exercise, sedentary behavior reduction, delivery by trained interventionists, and parental involvement, were not associated with significantly larger effects. 相似文献

Among the provisions of the recently signed Garrett Lee Smith Memorial Act, Congress called for the use of screening to detect adolescents who are at risk for suicide. After a review of the literature, 17 studies involving screening instruments and programs were identified. We addressed the question: What do we know about the demonstrated effectiveness and safety of screening as a tool or program to prevent suicide among adolescents? While youth suicide screening programs offer the promise of improving identification for those who need treatment the most, further research is essential to understand how, when, where, and for whom screening programs can be used effectively and efficiently. 相似文献

ABSTRACT— Mimicry facilitates the ability to understand what other people are feeling. The present research investigated whether this is also true when the expressions that are being mimicked do not reflect the other person's true emotions. In interactions, targets either lied or told the truth, while observers mimicked or did not mimic the targets' facial and behavioral movements. Detection of deception was measured directly by observers' judgments of the extent to which they thought the targets were telling the truth and indirectly by observers' assessment of targets' emotions. The results demonstrated that nonmimickers were more accurate than mimickers in their estimations of targets' truthfulness and of targets' experienced emotions. The results contradict the view that mimicry facilitates the understanding of people's felt emotions. In the case of deceptive messages, mimicry hinders this emotional understanding. 相似文献

ABSTRACT— A recent study demonstrated that observers' ability to identify targets in a rapid visual sequence was enhanced when they simultaneously listened to happy music. In the study reported here, we examined how the emotion-attention relationship is influenced by changes in both mood valence (negative vs. positive) and arousal (low vs. high). We used a standard induction procedure to generate calm, happy, sad, and anxious moods in participants. Results for an attentional blink task showed no differences in first-target accuracy, but second-target accuracy was highest for participants with low arousal and negative affect (sad), lowest for those with strong arousal and negative affect (anxious), and intermediate for those with positive affect regardless of their arousal (calm, happy). We discuss implications of this valence-arousal interaction for the control of visual attention. 相似文献

The Moderating Effect of Within‐Group Similarity on Change in a Strengths‐Based Programme for Incarcerated Young Men 下载免费PDF全文

Many youth who are incarcerated within juvenile correctional facilities experience mental health disorders, histories of victimization and suicide ideation. Strengths‐based intervention programmes are intended to enhance participants' resilience against such challenges. However, little is known about how the composition of intervention groups contributes to programmes' efficacy. This study addresses the impact of within‐group similarity on the success of a strengths‐based intervention for incarcerated young men (n = 141). Similarity was assessed in terms of self‐reported demographics and behaviours and belief systems. Youths' masculine ideology, caring and cooperative behaviours, ethnic pride and respect for differences, self‐efficacy regarding education and non‐violence, and attitudes about criminal behaviour were measured before and after intervention. Results indicate that participants' caring and cooperative behaviour increased during the intervention. However, their education‐related self‐efficacy was reduced, and the perceived benefits of criminal activity increased. These changes were moderated by group composition: less similarity between participants and their group members was associated with less negative change. In the context of juvenile corrections facilities, where staying the same may be a relatively positive outcome, perhaps the more relevant question is not which processes and characteristics of others better enable youth to change but which experiences help them retain positive aspects of themselves.

Exploring Perceived Social Support from Peer Facilitators in an HIV Treatment Adherence Intervention for African American Patients: A Content Analysis of Participant Perspectives 下载免费PDF全文

HIV treatment adherence interventions increasingly rely on peer facilitators to promote treatment adherence and improve patient retention, yet little is known about how participants perceive the role performed by peer facilitators. The present study examined participant perceptions in terms of the social support from peer facilitators in a hospital‐based intervention in Chicago. Content analysis was conducted with reference to four types of social support (instrumental, informational, emotional and affiliational) on exit interviews with 11 participants enrolled in the intervention that targeted African‐American patients living with HIV/AIDS. We examined how the type of social support perceived by participants was related to their self‐reported behaviours in three domains: adherence, sexual safety and general coping. Our analysis revealed that most participants perceived informational and emotional support from their peer facilitators, followed by instrumental support. Affiliational support was the least frequently perceived type of social support. We found that perceived informational support from peer facilitators with regard to adherence had greater impact and credibility amongst participants than the same type of support from medical providers. Informational support was cited most frequently with regard to influencing adherence and sexual safety behaviours, whereas perceived emotional support was cited primarily with helping participants cope with HIV.

The study tests the hypothesis that conditional probability judgments can be influenced by causal links between the target event and the evidence even when the statistical relations among variables are held constant. Three experiments varied the causal structure relating three variables and found that (a) the target event was perceived as more probable when it was linked to evidence by a causal chain than when both variables shared a common cause; (b) predictive chains in which evidence is a cause of the hypothesis gave rise to higher judgments than diagnostic chains in which evidence is an effect of the hypothesis; and (c) direct chains gave rise to higher judgments than indirect chains. A Bayesian learning model was applied to our data but failed to explain them. An explanation-based hypothesis stating that statistical information will affect judgments only to the extent that it changes beliefs about causal structure is consistent with the results. 相似文献

Implementing Housing First Across Sites and Over Time: Later Fidelity and Implementation Evaluation of a Pan-Canadian Multi-site Housing First Program for Homeless People with Mental Illness 下载免费PDF全文

This article examines later fidelity and implementation of a five‐site pan‐Canadian Housing First research demonstration project. The average fidelity score across five Housing First domains and 10 programs was high in the first year of operation (3.47/4) and higher in the third year of operation (3.62/4). Qualitative interviews (36 key informant interviews and 17 focus groups) revealed that staff expertise, partnerships with other services, and leadership facilitated implementation, while staff turnover, rehousing participants, participant isolation, and limited vocational/educational supports impeded implementation. The findings shed light on important implementation “drivers” at the staff, program, and community levels. 相似文献
