Previous work from our laboratory showed that intermittently re-exposing rats to reinforcement for lever pressing in a training (A) context, while eliminating lever pressing in a second (B) context, increased ABA renewal of lever pressing relative to rats that experienced only Context B during response elimination. In the current study, we replicated these procedures while assessing renewal in the presence of a novel context (i.e., ABC renewal). Unlike the findings described above, renewal was reduced in the group that experienced re-exposure to Context A during lever-press elimination relative to rats that experienced only Context B. These findings suggest that alternating between contexts associated with reinforcement and extinction during treatment reduces the probability that organisms will respond in novel contexts. These outcomes may be the result of discrimination and/or generalization processes. Moreover, this training procedure may offer a potential mitigation strategy for ABC renewal.  相似文献

Scholars are paying increasing attention to the “dark side” of citizenship behavior. One aspect of this dark side that has received relatively scant attention is “helping pressure”—an employee's perception that s/he is being encouraged to, or otherwise feels that s/he should, enact helping behavior at work. Drawing from theory associated with work stress, we examine affective and cognitive mechanisms that potentially explain why helping pressure, counterintuitively, may lead employees to engage in deviant behavior instead. Beyond examining these possible mechanisms, we also answer calls to identify a potential buffer to these effects. Drawing from self-determination theory, we examine how an employee's intrinsic motivation for citizenship may lessen the deleterious consequences of helping pressure at work. In two studies (a within-individual experience-sampling study and a two-wave between-individual study), we find consistent evidence that helping pressure has a positive indirect relationship with deviant behavior through increased negative affect. Further, we find evidence that intrinsic motivation for citizenship weakens the positive relationship of helping pressure with negative affect, buffering the indirect effect on subsequent deviant behavior. Theoretical and practical implications of these findings for the study of helping pressure at work are discussed.  相似文献

The purpose of this research is to construct and validate a multi-dimensional scale of Anti-social Behavior (hereafter ASB) in a Western higher education context (i.e., USA). To achieve this, four studies, each with a different sample, were performed. Study 1 (n = 150) followed an exploratory design to generate a pool of potential items measuring ASB. Study 2 (n = 254) explored the dimensionality of the items produced in Study 1 using exploratory factor analysis (EFA) and reliability measures. Study 3 (n = 654) confirmed the factorial structure from Study 2 and assessed the measurement model invariance using structural equation modeling (SEM). Finally, Study 4 (n = 287) assessed the predictive validity of the ASB measure through testing a hypothetical path model linking ASB to narcissism and Machiavellianism via an SEM procedure. In total, our research findings conclude that the ASB measurement model is a two-factor multi-dimensional structure comprising: Interpersonal Antagonistic Behavior (six items) as well as Indirect Distractive Behavior (four items). The research and practical implications for universities are thereafter discussed.  相似文献

This study applies an intervention based on autonomy support through dialogic learning to examine effects on motivation and the promotion of physical activity and sport involvement during schoolchildren’s leisure time. One hundred and two primary school students, aged 11–13 years, participated (M = 10.93, SD = 0.75). The sample was divided into two groups: an experimental group (49 students) and a control group (53 students). A quasi-experimental study was conducted in physical education classes over the course of 9 months. Assessments of autonomy support from teachers, family, and peers; basic psychological needs; self-determined motivation in physical education and during leisure time; planned behavior variables; physical activity intention; and estimated and actual physical exercise behavior time were included in the model. Following the intervention, the results revealed that greater autonomy support by the teacher, the family and peers, satisfaction of the basic psychological needs, self-determined motivation during physical education class and during free time, greater perceived control, favorable attitude and intention to engage in physical activity contributed to the explanation of student physical activity involvement. These results suggest that when students receive extensive social support from diverse social agents that essential precursors to physical activity are strengthened and contribute to increased motivation and actual physical activity involvement. Efforts to promote effective communications with students and other pedagogical efforts, such as providing dialogic learning opportunities, should be considered in order to strengthen physical activity motivation and involvement in students.  相似文献

There is high variability in efficacy for interventions for youth with disruptive behavior problems (DBP). Despite evidence of the unique correlates and critical consequences of girls’ DBP, there is a dearth of research examining treatment efficacy for girls. This meta-analysis of 167 unique effect sizes from 29 studies (28,483 youth, 50% female; median age: 14) suggests that existing treatments have a medium positive effect on DBP (g = .33). For both boys and girls, the most effective interventions included (a) multimodal or group format, (b) cognitive skills or family systems interventions, and (c) length-intensive programs for (d) younger children. Boys demonstrated significantly greater treatment gains from group format interventions compared to girls, which is particularly important given that the group program format was the most prevalent format for boys and girls, with 14 studies involving 10,433 youth encompassing this category. This is the first meta-analysis to examine the effect of program characteristics in a sample of programs selected to be specifically inclusive of girls. Given that girls are underrepresented in intervention research on DBP, findings are discussed in terms of gender-responsive considerations and elucidating how key aspects of program structure can support more effective intervention outcomes for youth.  相似文献

The last several decades have witnessed a structural change in politics toward cultural and identity conflicts, accompanied by the rise of populist radical right (PRR) parties. However, we know surprisingly little about the psychological or cognitive-motivational factors underlying PRR support. We claim that uncertainty avoidance (UA)—an epistemic avoidance motivation—represents a central motive because UA resonates with the PRR platform and precedes common predictors of PRR voting. Using data from the 2017 Austrian National Election Study, we found that UA was indeed indirectly associated with a higher likelihood of PRR voting. This association is because greater UA fostered right-wing sociocultural views, whereas associations with populist attitudes or expected government competence were more ambiguous. PRR parties appear to offer “certainty,” but as extreme parties, they also remain a “risky choice.” We conclude by discussing the contribution of a cognitive-motivational account to explain PRR voting.  相似文献

A robust research literature links parental spanking with negative behavioral outcomes for children, however, it remains unclear whether conditions in the community may moderate the associations between spanking and behavior problems in early childhood. In the current study, we examined whether community violence exposure moderated the associations of maternal spanking with externalizing and internalizing behavior problems of young children. The sample used in this study was urban families and their children ages 3–5 (n = 2,472). We used fixed effects regression models, which yield stronger statistical control for baseline behavior problems, selection bias, and omitted variables bias. Mother's spanking was associated with elevated levels of both externalizing (β = .037, p < .001) and internalizing (β = .016, p < .001) behavior problems. Community violence exposure also predicted higher levels of externalizing (β = .071, p < .01) and internalizing (β = .043, p < .05) behavior problems. Community violence exposure did not moderate the associations between maternal spanking and behavior problems. Professionals working with families should promote the use of nonphysical disciplinary practices, regardless of the level of violence and crime in the community in which the family resides.  相似文献

This study investigates whether fathers’ adverse childhood experiences (ACE) and attachment style reported during pregnancy predict fathers’ perception of child behavior assessed 12 months postpartum, expressed by the Parenting Stress Index (PSI), Child Domain. Prospective fathers (N = 835) were recruited to “The Little in Norway (LiN) study” (Moe & Smith) at nine well-baby clinics in Norway, with data collection composed of five time points during pregnancy and two time points postpartum (6 and 12 months). The main analyses included linear regression, path-analysis modeling, and intraclass correlation based on mixed effects modeling. First, linear regression analyses showed that neither fathers’ ACE nor attachment style significantly predicted perceived child behavior postpartum directly. Furthermore, path analyses showed that ACE and less secure attachment style (especially avoidant attachment) measured early in pregnancy strongly predicted negatively perceived child behavior, mediated by fathers’ mental health symptoms during pregnancy and partner disharmony postpartum. Second, intraclass correlation analyses showed that fathers’ perceived child behavior showed substantial stability between 6 and 12 months postpartum. Family interventions beginning in pregnancy may be most beneficial given that fathers’ early experiences and perceptions of attachment in pregnancy were associated with later partner disharmony and stress.  相似文献

The process of goal pursuit provides a unique opportunity to investigate real-life psychological implications of unethical behaviors. In two studies, we had participants recall the frequency of engaging in unethical behaviors during goal pursuit and report current experience of negative affect and meaning in life, during different goal states (i.e., ongoing vs. completed). Both studies revealed that meaning in life was negatively associated with unethical behaviors implemented in the process of pursuing a goal only after but not prior to goal completion. Negative affect, however, was positively associated with unethical behavior frequencies in both goal states. The current research helps integrate studies on personal goals and unethical behaviors, and sheds light on the dynamic consequences of engaging in unethical behaviors.  相似文献

This study extends research on the link between personality and Counterproductive Work Behavior (CWB) by investigating whether the implicit Affiliation, Achievement, and Power motives contribute to the prediction of CWB beyond basic personality traits. Employees high in Affiliation, Achievement, and Power motives may disengage from CWB because it is not rewarding and thwarts goal attainment. In Study 1 (N = 263), we found that Affiliation predicted self-rated CWB beyond traits. In Study 2 (N = 121), we found that Affiliation and Power predicted supervisor-rated CWB. Our findings thus suggest to also consider implicit motives as personality determinants of CWB.  相似文献
