Trajectories and predictors of indirect aggression: results from a nationally representative longitudinal study of Canadian children aged 2-10

The purposes of this study were to model the development of indirect aggression among a nationally representative sample of 1,401 Canadian children aged 4 at T2, 6 at T3, 8 at T4 and 10 at T5, and to examine predictors of trajectory group membership from T1 (age 2) child, familial, and parenting variables. Using a semi-parametric group-based modeling approach, two distinct trajectories were identified: "increasing users" comprising of 35% of the sample and "stable low users" comprising of 65% of the sample. Using logistic regression analyses to distinguish these two groups, we found that for girls, more frequent, increasing use of indirect aggression was associated with prior prosocial and physically aggressive behavior, low SES and low parental social support at age 2. For boys, increasing use of indirect aggression was associated with prior parenting issues at age 2-inconsistency and less positive parent-child interactions. Although this study provides unique information regarding the early development of indirect aggression and its predictors, more longitudinal research is needed to fully understand its development.

Intra‐sentential context effects on the interpretation of logical metonymy⋆

Verbs such as enjoy in the student enjoyed the book exhibit logical metonymy: enjoy is interpreted as enjoy reading. Theoreticalwork [Computational Linguistics 17 (4) (1991) 409; The Generative Lexicon, MIT Press, Cambridge, MA, 1995] predicts that this interpretation can be influenced by intra‐sentential context, e.g., by the subject of enjoy. In this article, we test this prediction using a completion experiment and find that the interpretation of a metonymic verb is influenced by the semantic role of its subject. We present a Bayesian model that accounts for the interpretation of logical metonymy and achieves a good fit on our experimental data. We show that the parameters of the model can be estimated from completion data or from corpus data.     

Rhétorique et dialectique chez Aristote

Rhetoric and dialectic are two distinct circles, but in intersection. Rhetoric is an application (among others) of the dialectic to public debates. The dialectic is then the intellectual tool of rhetoric, distinct from its emotive means of persuading. But each of them can be antistrophos to the other one because both of them belong to the same sublunar world, our world. Such is Aristotle's answer, both to the sophists and to Plato.

     

Evaluating the effects of discriminability on behavioral persistence during and following time‐based reinforcement

With four children with autism we evaluated a refinement to time‐based reinforcement designed to reduce response persistence when we simultaneously introduced time‐based reinforcement and extinction. We further evaluated whether this refinement mitigated response recurrence when all reinforcer deliveries ceased during an extinction‐only disruptor phase. The refinement involved increasing the saliency of the contingency change from contingent reinforcement (during baseline) to time‐based reinforcement by delivering different colored reinforcers during time‐based reinforcement. Behavioral momentum theory predicts that increasing the discriminability of the change from variable‐interval to variable‐time reinforcement should lead to faster reductions in responding. We present data on four participants, three of whom displayed response patterns consistent with the predictions of behavioral momentum theory during time‐based reinforcement. However, the participants showed more varied patterns of recurrent behavior during extinction. We discuss these results within a translational research framework focusing on strategies used to mitigate treatment relapse for severe destructive behavior, as time‐based reinforcement is one of the most commonly prescribed interventions for destructive behavior displayed by individuals with intellectual and developmental disabilities.     

Theoretical frameworks for working with harder to reach families: lines,curlicues, and spirals: comment on Donovan and Pocock

This article comments on the Donovan and Pocock articles appearing in this issue, both of which address the evolution of theory and practice in family therapy. An emphasis is placed on the importance of integration and a shared philosophy of theory and practice in our current political and economic managed care climate, in which it is critically important to embrace the integrated and chaotic whole of what is happening in theory and in practice.     

Religiosity Reduces Sexual Aggression and Coercion in a Longitudinal Cohort of College Men: Mediating Roles of Peer Norms,Promiscuity, and Pornography

Extensive literature suggests that religiosity is a protective factor in reducing a number of deviant behaviors, including sexual aggression (SA). Whereas previous research focused on the role of risky alcohol consumption in mediating the relationship between religiosity and SA, this study explores the hypothesized meditational paths from religiosity to SA and technology‐based coercive behavior (TBC) through peer norms, pornography consumption, and promiscuity. Findings from a four‐year longitudinal study of male college students suggest that peer norms and promiscuity mediate the relationship between religiosity and both outcome measures, while pornography consumption mediates the relationship between religiosity and TBC. These findings may inform ongoing practice and future research into possible mechanisms by which problematic sexual behaviors may be influenced.     

Effects of computer‐based training on procedural modifications to standard functional analyses

Few studies have evaluated methods for training decision‐making when functional analysis data are undifferentiated. The current study evaluated computer‐based training to teach 20 graduate students to arrange functional analysis conditions, analyze functional analysis data, and implement procedural modifications. Participants were exposed to training materials using interactive software during a 1‐day session. Following the training, mean scores on the posttest, novel cases probe, and maintenance probe increased for all participants. These results replicate previous findings during a 1‐day session and include a measure of participant acceptability of the training. Recommendations for future research on computer‐based training and functional analysis are discussed.
