Children may recruit their teachers' attention at undesirably high rates or at inconvenient times. Tiger and Hanley (2004) described a multiple-schedule procedure to reduce ill-timed requests, which involved providing children with two distinct continuous signals that were correlated with periods in which teacher attention was either available or unavailable. The current study extended the application of multiple schedules by evaluating the effectiveness of the procedure when implemented by private-school teachers in 3 elementary classrooms. Following the introduction of the multiple schedules, student approaches toward their teacher were maintained during desirable periods but were minimized during undesirable periods.  相似文献

Studies of social power use have frequently employed self‐report instruments that are prone to response bias. In the present study, an experimental design was conducted in which 100 participants were asked to gain compliance from in‐group and out‐group members. We tested whether harsh tactics—often used for elevating self‐image at the dyadic level—also provide a means for gaining advantage at the group level. For this purpose, self‐esteem and self‐efficacy were examined as possible moderators. Findings indicated that self‐esteem interacted with target group: Low self‐esteem participants used harsh tactics more frequently toward in‐group than out‐group members; and moderate and high self‐esteem participants used harsh tactics more frequently toward out‐group than in‐group members. The process involved in this interaction is discussed.  相似文献

Three studies assessed the impact of self-esteem threat on death-thought accessibility (DTA). Increased DTA resulted from three distinct types of self-esteem threat. Studies 1 and 2 employed negative feedback procedures in which participants were told that they scored below average on an intelligence test (Study 1), or that their personality was incongruent for their desired career path (Study 2). In Study 3, participants were led to believe that they would give an ill prepared speech in front of their peers. In Studies 1 and 2 DTA was assessed via reaction times on a lexical decision task, while Study 3 employed a word-fragment completion task. Study 3 demonstrated the DTA buffering effect of fortifying self-esteem via self-affirmation. Discussion focused on general implications for TMT, self-esteem, and mental health.  相似文献

Does Islamic appearance increase aggressive tendencies, and what role does affect play in such responses? In a computer game, participants made rapid decisions to shoot at armed people, some of whom wore Islamic head dress. We predicted and found a significant bias for participants to shoot more at Muslim targets. We also predicted and found that positive mood selectively increased aggressive tendencies towards Muslims, consistent with affect-cognition theories that predict a more top-down, stereotypical processing style in positive mood. In contrast, induced anger increased the propensity to shoot at all targets. The relevance of these results for our understanding of real-life negative reactions towards Muslims is discussed, and the influence of affective states on rapid aggressive responses is considered.  相似文献

The experience of mixed emotions increases with age. Socioemotional selectivity theory suggests that mixed emotions are associated with shifting time horizons. Theoretically, perceived constraints on future time increase appreciation for life, which, in turn, elicits positive emotions such as happiness. Yet, the very same temporal constraints heighten awareness that these positive experiences come to an end, thus yielding mixed emotional states. In 2 studies, the authors examined the link between the awareness of anticipated endings and mixed emotional experience. In Study 1, participants repeatedly imagined being in a meaningful location. Participants in the experimental condition imagined being in the meaningful location for the final time. Only participants who imagined "last times" at meaningful locations experienced more mixed emotions. In Study 2, college seniors reported their emotions on graduation day. Mixed emotions were higher when participants were reminded of the ending that they were experiencing. Findings suggest that poignancy is an emotional experience associated with meaningful endings.  相似文献

We evaluated the validity of DIBELS (Dynamic Indicators of Basic Early Literacy Skills) ORF (Oral Reading Fluency) for predicting performance on the Florida Comprehensive Assessment Test (FCAT-SSS) and Stanford Achievement Test (SAT-10) reading comprehension measures. The usefulness of previously established ORF risk-level cutoffs [Good, R.H., Simmons, D.C., and Kame’enui, E.J. (2001). The importance and decision-making utility of a continuum of fluency-based indicators of foundational reading skills for third-grade high-stakes outcomes. Scientific Studies of Reading, 5, 257–288.] for third grade students were evaluated on calibration (nS1 = 16,539) and cross-validation (nS2 = 16,908) samples representative of Florida's Reading First population. The strongest correlations were the third (February/March) administration of ORF with both FCAT-SSS and SAT-10 (rS = .70–.71), when the three tests were administered concurrently. Recalibrated ORF risk-level cut scores derived from ROC (receiver-operating characteristic) curve analyses produced more accurate identification of true positives than previously established benchmarks. The recalibrated risk-level cut scores predict performance on the FCAT-SSS equally well for students from different socio-economic, language, and race/ethnicity categories.  相似文献

The study examined whether the Power Interaction Model is applicable for explaining the choice of power tactics in conflict situations among Israeli married couples. In addition, gender role ideology was tested as a moderator of the relationship between power usage and marital satisfaction. Seventy-eight couples reported on self usage and spouse’s usage of power tactic behaviors during conflicts and completed questionnaires assessing marital satisfaction, gender role ideology (traditional, liberal) and demographics. Findings indicated greater agreement within couples for harsh rather than for soft tactic preference. As expected, preference for harsh tactics was associated with lower marital satisfaction yet gender role ideology moderated this association. The role of conflict and power usage in traditional and liberal families was addressed.  相似文献

Three categories of crime-scene behaviors (violence, interpersonal involvement, and criminal sophistication) among a group of 22 serial and 22 single-victim rapists were studied. Findings indicate that serial rapists were more likely to display a higher level of criminally sophisticated behaviors to avoid detection, whereas single-victim rapists were more likely to behave violently and engage in some form of interpersonal involvement with their victims. Implications of these findings for investigation and for understanding offenders' behavior are discussed.  相似文献

In three studies using both laboratory and field data, we show that the focal competitor’s strengths and weaknesses feature more prominently in predictions of the outcomes of future competitions than do the strengths and weaknesses of the opponents. People are more confident when their own side is strong, regardless of how strong the competition is. We show that this effect is driven by the fact that people have better information about their own side than the other side, in part because they preferentially seek out information about their own side. Implications for theories of decision making in competitive settings are discussed.  相似文献

A history of childhood sexual abuse (CSA) increases the risk of suicidal behavior and the lifetime number of suicide attempts in adults with BPD. Despite a strong association, specific variables mediating the relationship between CSA and adult suicidal behavior in BPD have not been identified. This study examined risk factors for suicidal behavior as potential mediators of the relationship between CSA and suicide attempts in 151 men and women with BPD. Diagnostic, clinical, and psychosocial risk factors, as well as CSA, and suicidal behaviors, were assessed by standardized interviews or self-rated measures. Psychotic and schizotypal symptoms, and poor social adjustment, were associated with both CSA and suicidal behavior, and partially mediated the relationship between CSA and attempter status. Psychotic and schizotypal symptoms in BPD define a vulnerability to cognitive and perceptual distortions under stress. They increase the likelihood of suicidal behavior in BPD, especially in the absence of mitigating social support. A theoretical model for suicidal behavior in BPD is presented which integrates direct, mediated, and moderated pathways between childhood sexual abuse and temperament, adolescent and adult risk factors, and suicidal behavior.  相似文献
