The study of equivalence relations exhibited by individuals with mental retardation and language limitations holds the promise of providing information of both theoretical and practical significance. We reviewed the equivalence literature with this population, defined in terms of subjects having moderate, severe, or profound mental retardation. The literature includes 55 such individuals, most of whom showed positive outcomes on equivalence tests. The results to date suggest that naming skills are not necessary for positive equivalence test outcomes. Thus far, however, relatively few subjects with minimal language have been studied. Moreover, we suggest that the scientific contributions of studies in this area would be enhanced with better documentation of language skills and other subject characteristics. With recent advances in laboratory procedures for establishing the baseline performances necessary for equivalence tests, this research area is poised for rapid growth.  相似文献

In this paper a unified framework for dealing with a broad family of propositional multimodal logics is developed. The key tools for presentation of the logics are the notions of closure relation operation and monotonous relation operation. The two classes of logics: FiRe-logics (finitely reducible logics) and LaFiRe-logics (FiRe-logics with local agreement of accessibility relations) are introduced within the proposed framework. Further classes of logics can be handled indirectly by means of suitable translations. It is shown that the logics from these classes have the finite model property with respect to the class of -formulae, i.e. each -formula has a -model iff it has a finite -model. Roughly speaking, a -formula is logically equivalent to a formula in negative normal form without occurrences of modal operators with necessity force. In the proof we introduce a substantial modification of Claudio Cerrato's filtration technique that has been originally designed for graded modal logics. The main core of the proof consists in building adequate restrictions of models while preserving the semantics of the operators used to build terms indexing the modal operators.  相似文献

Racial and ethnic diversity is increasing in the US Army and women are moving into more combat roles. This puts minority soldiers at risk for being underrepresented in their work units. Tokenism theory predicts that when a work group has less than 15% representation in a social group, the numerically underrepresented minority (i.e., token) members are subject to three disadvantages: higher visibility, informal isolation, and role encapsulation. In the Army, where many companies contain small numbers of women and racial minorities, some soldiers may face additional stressors and constraints. We explored psychosocial, organizational, and health outcomes of all identifiable token women (= 4,425) and Black soldiers (= 5,040). Tokens were remarkably similar to non-tokens and majority soldiers on outcomes such as coping skills, adaptability, organizational trust, sleep, substance use, and pain. The intersection of token status in terms of race and gender was not related to any appreciable differences. One potential explanation is the shared Army culture that emphasizes group unity and the importance of the mission above individual characteristics and goals. The Army depends on cohesion, organizational identification, and commitment to the group in order to reduce stress and anxiety, and to maximize combat performance. For soldiers who have internalized this culture, it could be easier to see past individual differences such as gender and race and identify others in the unit as fellow soldiers primarily.  相似文献

Abstract

The social meaning model asserts that some nonverbal behaviors have consensually recognized relational meanings within a given social community. According to this perspective, the interpretations made by encoders, decoders, and 3rd-party observers of the same nonverbal behavior should be congruent. The authors applied the model to the identification of relational message interpretations of nonverbal matching behavior. Confederates either matched or did not match the nonverbal behaviors of conversational participants while being watched by nonparticipant observers. All three nonconfederate participants provided interpretations of the confederates' relational messages. As the authors had expected, there were moderate correlations between the 3 perspectives, with observers usually providing less favorable assessments than the conversational participants. The authors also examined the influence of positive and negative stimulus behavior on relational message interpretations.  相似文献

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

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

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
