In a typical transposition task, an animal is presented with a single pair of stimuli (for example, S3+ S4−, where plus and minus denote reward and nonreward and digits denote stimulus location on a sensory dimension such as size). Subsequently, an animal is presented with a testing pair that contains a previously reinforced or nonreinforced stimulus and a novel stimulus (for example, S2–S3 and S4–S5). Does the choice of a novel S2 instead of previously reinforced S3 in a testing pair S2–S3 indicate that the animal has learned a relation (i.e., “select smaller”)? This review of empirical evidence and theoretical accounts shows that an organism''s behavior in a transposition task is undoubtedly influenced by prior reinforcement history of the training stimuli (Spence, 1937). However, it is also affected by two other factors that are relational in nature—a similarity of two testing stimuli to each other and an overall similarity of the testing pair as a whole to the training pair as a whole. The influence of the two latter factors is especially evident in studies that use multiple pairs of training stimuli and a wide range of testing pairs comprising nonadjacent stimuli (Lazareva, Miner, Young, & Wasserman, 2008; Lazareva, Wasserman, & Young, 2005). In sum, the evidence suggests that both prior reinforcement history and relational information affect an animal''s behavior in a typical transposition task.  相似文献

Applying resource control theory and social exchange theory, we examined the social network conditions under which elementary age children were likely to engage in relational aggression. Data on classroom peer networks and peer‐nominated behaviors were collected on 671 second‐ through fourth‐grade children in 34 urban, low‐income classrooms. Nested regression models with robust cluster standard errors demonstrated that the association between children's number of relationships and their levels of relational aggression was moderated by the number of relationships that their affiliates had. Children with more peer relationships (i.e., higher network centrality) exhibited higher levels of relational aggression, but only when these relationships were with peers who had fewer connections themselves (i.e., poorly connected peers). This finding remained significant even when controlling for common predictors of relational aggression including gender, overt aggression, prosocial behavior, victimization, social preference, and perceived popularity. Results are discussed in terms of their implications for advancing the literature on childhood relational aggression and their practical applications for identifying children at risk for these behaviors.  相似文献

Acknowledging the place of love in couple therapy requires therapists to reflect upon what love means to them. We propose that love defines the couple relationship and in turn the relationship defines love. In this article we explore and focus on our conceptualization of love and its influence on couple therapy. Exploring love in the context of the phrase ‘I love you’ leads us to consider built‐in contradictions. These contradictions can be contextualized and understood in a relational dialectic framework. Implications for therapy are explored and briefly illustrated in a case vignette.  相似文献

Theory-of-mind (ToM) involves modeling an individual's mental states to plan one's action and to anticipate others' actions through recursive reasoning that may be myopic (with limited recursion) or predictive (with full recursion). ToM recursion was examined using a series of two-player, sequential-move matrix games with a maximum of three steps. Participants were assigned the role of Player I, controlling the initial and the last step, or of Player II, controlling the second step. Appropriate for the assigned role, participants either anticipated or planned Player II's strategy at the second step, and then determined Player I's optimal strategy at the first step. Participants more readily used predictive reasoning as Player II (i.e., planning one's own move) than as Player I (i.e., anticipating an opponent's move), although they did not differ when translating reasoning outcome about the second step to optimal action in the first step. Perspective-taking influenced likelihood of predictive reasoning, but it did not affect the rate at which participants acquired it during the experimental block. We conclude that the depth of ToM recursion (related to perspective-taking mechanisms) and rational application of belief-desire to action (instrumental rationality) constitute separate cognitive processes in ToM reasoning.  相似文献

Psychopathy is a robust predictor of overt physical aggression that may also be relevant to relational aggression (RA). This study was conducted to investigate the utility of psychopathic personality traits in the prediction of RA in a sample of 291 college students. Hierarchical multiple regression analyses indicated that both primary and secondary psychopathic traits explained additional variance in general/peer and romantic RA beyond physical aggressiveness. Consistent with previous research, no gender differences were found on either form of RA, challenging the popular stereotype of RA as a female behavior. Moreover, psychopathic traits were not differentially predictive of RA by gender or level of physical aggressiveness. Implications of these findings for research and clinical practice are discussed.  相似文献

Various studies have found that viewing physical or relational aggression in the media can impact subsequent engagement in aggressive behavior. However, this has rarely been examined in the context of relationships. Accordingly, the aim of this study was to examine the connection between viewing various types of aggression in the media and perpetration of aggression against a romantic partner. A total of 369 young adults completed a variety of questionnaires asking for their perpetration of various forms of relationship aggression. Participants' exposure to both physical and relational aggression in the media was also assessed. As a whole, we found a relationship between viewing aggression in the media and perpetration of aggression; however, this depended on the sex of the participant and the type of aggression measured. Specifically, exposure to physical violence in the media was related to engagement in physical aggression against their partner only for men. However, exposure to relational aggression in the media was related to romantic relational aggression for both men and women.  相似文献

Introduction and objectivesAfter leading a validation of questionnaires about three fundamental needs in French language (need for cognition, closing and evaluation), we tested in two studies that fundamental needs could be subjected to social constraints and could be considered differently than exclusively like stable personality characteristics and motivational drivers of action.MethodUsing the paradigm of judges (study 1) and the paradigm of identification (study 2), the results argue for a normative approach, at least as regards the need for cognition and assess.ResultsThe results of the first study show that individuals consider more favorably targets with strong need rather than low need and especially in social contexts with high social utility (that is to say, the professional context in comparison with the friendly context). The results of the second study show that when the questionnaires about needs “as would a person having been previously well or poorly assessed” participants get higher scores high on the need for cognition questionnaire in the first case than in the second. The results regarding the need for closure are more mixed.ConclusionThe results are discussed in a socio-normative perspective.  相似文献

This study is one of the first tests of key implicit claims of Hay and Nye’s theory of children’s spirituality and spiritual development. Two quasi-experimental studies tested two claims: that exposure to six conditions posited as fostering relational consciousness in a programme of spiritual formation promotes spiritual well-being; that the effect of the conditions continues after exposure ends. The results for Study One revealed that length of exposure to any of the six conditions was not a significant predictor of spiritual well-being, F(3, 179)?=?1.49, p = 0.22. Study Two results indicated that as the length of time since exposure increased so did spiritual well-being, r(38)?=?0.39, p = 0.01 at the bivariate level, and F(4, 35)?=?2.4, p = 0.06 in the regression. These results reveal a possible relationship between exposure to the six conditions and spiritual well-being.  相似文献

To explore the relationship between parental phubbing (PP) and adolescent online hostility and its' psychological mechanism, 689 Chinese adolescents were recruited to complete a paper-and-pencil questionnaire. We took cyber flaming (CF) as an overall category for hostile online communication to investigate the relationship between PP and CF and the mediating role of perspective-taking (PT) in this relationship and examined whether there is a sex difference in this process. After controlling the average daily online time, the results showed that PP predicted adolescent CF positively. The relationship between PP and CF was partially mediated by PT. The effect of PP on PT was moderated by sex, with the result being significant only for boys. Related findings and future directions were discussed.  相似文献

Dimensions of negative parenting, including permissive, authoritarian, and psychologically controlling parenting behaviors, are associated with children's engagement in relational aggression. However, some youth may be more strongly influenced by negative parenting than others, and effects may depend on whether aggression is proactive or reactive in function. In a community sample of 236 preadolescent children followed over 1 year, we examined whether children's skin conductance level reactivity (an index of “fight or flight” response) and gender moderated links between parents' self-reported negative parenting behaviors and increases in children's teacher-reported proactive and reactive relational aggression. Findings indicated that negative parenting predicted increases in proactive and reactive relational aggression, and, consistent with differential susceptibility theory, effects often emerged among highly reactive youth. Associations between negative parenting and proactive relational aggression emerged for boys but not girls. Results tentatively suggest that associations between parenting and aggression vary by the function of aggression, children's physiological reactivity to stress, and gender, although results should be interpreted with caution due to high levels of missing data. Implications for theory and intervention are discussed.  相似文献
