The authors describe two pilot studies examining the potential benefits of Lunch Buddy (LB) mentoring, a manualized approach to school-based mentoring. LB mentoring takes place during the school lunch period and is designed to promote positive changes in children's peer relationships. In both studies, changes in peer victimization were assessed after one and three semesters of LB mentoring. In the first study, LB mentors were paired with elementary school children (N = 24) identified by child and teacher reports as victimized by peers. Results revealed significant declines in self- and teacher-rated victimization after one and three semesters of mentoring. In the second study, LB mentors were paired with victimized children who also engaged in bullying behavior (N = 23). Results indicated significant declines in self- and teacher-ratings of peer victimization after three semesters of mentoring. In both studies, ratings of perceived harm were low and ratings of satisfaction were high. Discussed are the implications of these findings for future research and for efforts to develop a nonharmful way to help children who are repeatedly victimized.  相似文献

Bystander intervention has been increasingly applied to prevent sexual violence on college campuses. Its underlying theory assumes unidirectional relationships between variables, predicting that bystander behaviors (i.e., actions taken to intervene in sexual violence situations) will be influenced by bystander intentions (BI; i.e., likelihood to intervene in the future), which in turn will be affected by bystander efficacy (BE; i.e., confidence to intervene). One question for theory is whether a reciprocal relationship exists between BI and BE. We used structural equation modeling (SEM) with longitudinal data to test unidirectional and reciprocal causal relations between BI and BE. Participants (n = 1390) were students at a northeastern US university. Four models were examined using SEM: (1) a baseline model with autoregressive paths; (2) a model with autoregressive effects and BI predicting future BE; (3) a model with autoregressive effects and BE predicting future BI; and, (4) a fully cross‐lagged model. Results indicated that reciprocal causality was found to occur between BI and BE. In addition, a final model demonstrated indirect effects of a bystander intervention program on bystander behaviors through both BI and BE at different time points. Implications for theory and practice are described, and directions for future research discussed.  相似文献

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and policy implications will be discussed.  相似文献

Objectives: Within a trial of medical and surgical treatments for gastro-esophageal reflux disease (GORD), involving randomised arms and preference arms, we tested the applicability of the Beliefs about Medicines Questionnaire (BMQ) and developed and tested the validity of a new Beliefs about Surgery Questionnaire (BSQ). Methods: Patients with GORD (N = 43) were interviewed to elicit their beliefs about medical and surgical treatments. These contributed to the development of BSQ items. The BMQ and BSQ were completed by trial participants at baseline (randomised trial: N = 325; preference trial: N = 414). Factor analysis and discriminant function analysis were used to assess validity. Results: Principal components analysis (PCA) largely replicated the four-factor BMQ structure. PCA of the combined BMQ/BSQ yielded six factors explaining 54.5% variance. BSQ items loaded onto distinct factors, demonstrating divergence from BMQ. As predicted, BMQ/BSQ scores enabled correct classification of 78.5% of participants to medication and surgery groups in the preference trial (χ²(6) = 205.9, p < 0.001) but only 54.5% (no better than chance) in the randomised trial (χ²(6) = 9.4, p = 0.154). Conclusions: The BSQ is a valid measure of perceptions about surgical treatments for GORD. With the BMQ, it provides information that may guide patients’ choices about treatment. This measure may be applicable to other conditions.  相似文献

Individual differences are often incorporated into experimental research to elucidate inconsistent effects. We argue that the inclusion of such differences into established and seemingly straightforward findings is imperative to the goal of reaching a more complete understanding about the processes of interest. Drawing on research on the cognitive effects of positive affect, we illustrate how integrating individual differences in cognitive processing styles to this literature might lead to a more nuanced understanding of the impact of affect on cognitive processes. The addition of individual differences to psychological research should be seen as a means to a thorough scientific comprehension of a topic rather than as burdensome caveats to otherwise straightforward findings.  相似文献

Research into lying about intentions is relatively new. Studies have suggested that lying about intentions can be detected with statement analysing methods. This article describes two experiments. The first experiment investigates how much spatial and temporal detail is given by people who are discussing a true or false intention in a 26‐question interview. The results showed that those with a true intention gave more spatial and temporal details. The second experiment examines these details in a one‐question interview and whether the amount of temporal detail given can be manipulated by the phrasing of the question. The results showed that the amount of detail is much lower in these short interviews, but can be increased with specific phrasing. The theoretical and practical implications of these results are discussed. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

The present study examined the antecedents of trust among operational Air Force fighter pilots for an automatic ground collision avoidance technology. This technology offered a platform with high face validity for studying trust in automation because it is an automatic system currently being used in operations by the Air Force. Pilots (N = 142) responded to an online survey which asked about their attitudes toward the technology and assessed a number of psychological factors. Consistent with prior research on trust in automation, a number of trust antecedents were identified which corresponded to human factors, learned trust factors, and situational factors. Implications for the introduction of novel automatic systems into the military are discussed.  相似文献

A substantial body of evidence demonstrates that infants understand the meaning of spoken words from as early as 6 months. Yet little is known about their ability to do so in the absence of any visual referent, which would offer diagnostic evidence for an adult‐like, symbolic interpretation of words and their use in language mediated thought. We used the head‐turn preference procedure to examine whether infants can generate implicit meanings from word forms alone as early as 18 months of age, and whether they are sensitive to meaningful relationships between words. In one condition, toddlers were presented with lists of words taken from the same taxonomic category (e.g. animals or body parts). In a second condition, words taken from two other categories (e.g. clothes and food items) were interleaved within the same list. Listening times were found to be longer in the related‐category condition than in the mixed‐category condition, suggesting that infants extract the meaning of spoken words and are sensitive to the semantic relatedness between these words. Our results show that infants have begun to construct the rudiments of a semantic system based on taxonomic relations even before they enter a period of accelerated vocabulary growth.  相似文献

This study examined the direct and moderator effects of number of perpetrators and gender of victim on interpersonal behaviour in stranger rape. Crime scene behaviours representative of hostility, involvement, control, and offender penetration in rape were examined for 496 UK, police‐recorded cases of stranger rape. Cases were grouped according to victim gender (male or female) and number of perpetrators (lone or multiple). This resulted in four groups (lone female, lone male, multiple female, and multiple male) with 124 cases in each. Binary logistic regression and one‐way analysis of variance were used to investigate the relationships between the two predictor variables and 11 criterion variables. Significant direct effects of number of perpetrators were found whereby multiple perpetrator offences were more likely to involve violence and less likely to involve involvement interactions than lone perpetrator offences. Significant direct effects of victim gender were also found whereby male victims were more likely than female victims to experience hostile interactions and be threatened with a weapon and were less likely to experience offender penetration and involvement interactions. Significant crossover interactions were also found for four hostility variables. The utility of the findings are discussed in relation to crime prevention, victim support, and offender intervention.
