TREATING CHRONIC FOOD REFUSAL IN YOUNG CHILDREN: HOME-BASED PARENT TRAINING

We evaluated the effects of a behavioral parent training program on parent and child feeding-related behaviors in the home. We trained mothers to initiate regular offerings of previously rejected (target) foods and to provide contingent attention (i.e., specific prompts, positive reinforcement) to increase their child's acceptance of nonpreferred foods. For 1 subject, we also directed training at increasing self-eating. Results of a nonconcurrent multiple baseline design across 3 mother-child dyads demonstrated that, with training, all mothers increased offerings of target foods and use of specific prompts, and 2 mothers increased levels of positive attention. In turn, children increased their acceptance of target foods and self-eating, thus demonstrating the functional effects of parent training on in-home mealtimes. Temporary increases in food refusals occurred when treatment was initiated but declined as treatment continued. We discuss the results in terms of the potential benefits and limitations of a home-based treatment model.     

THE LIMITS OF PRAGMATISM AND THE LIMITS OF REALISM

Abstract. I argue here for a limited version of pragmatism—called conceptual pragmatism—that recognizes that conceptual systems are to be evaluated according to their usefulness for helping us get around in the world. Once a conceptual system is in place, however, the truth of sentences is a matter of both empirical tit and coherence with the rest of our knowledge. The error of critical realists is to fail to take into account the limited conceptual relativity that is to be expected on the basis of conceptual pragmatism. The conceptual realist thesis applies equally in science and theology.     

The ethics of HIV testing by physicians

This essay argues that informed consent remains desirable for both moral and practical reasons in regard to HIV testing by physicians. At the very least, respect for consent preserves patient control over treatment and affords the opportunity for education about the nature of HIV-related disorders. Nevertheless, there do appear to be circumstances under which involuntary testing may occur especially when health care workers may have become occupationally exposed to risk of HIV infection. To eliminate conflicts between health workers and their patients, however, it is desirable to work to eliminate the stigmatizing and discriminatory effects of HIV infection that can induce persons to resist testing.     

TRAINING INTERACTIONAL BEHAVIORS OF ADULTS WITH DEVELOPMENTAL DISABILITIES: A SYSTEMATIC REPLICATION AND EXTENSION

This study was a replication and extension of research by Foxx, McMorrow, Bittle, and Ness (1986) that assessed generalization effects of a social skills training program on the interactional behavior of adults with developmental disabilities. Target skills were a verbal action or reaction in six skill areas that specifically addressed the participants' skill deficits. In the present study, we trained 5 adult residents of a group home across these six skill areas using the “Sorry” game format and the scoring criteria described by Foxx et al. We extended the results of Foxx et al. by (a) using pretreatment assessment procedures to identify participants' specific skill deficits, (b) training all residents in the natural environment, (c) training participant—participant interactions, (d) training participants to respond to four of the six skill areas through the use of a role-play procedure, and (e) omitting rewards, criterion levels, and self-monitoring. Additionally, the trainer in the present study modeled correct responses only as an error correction procedure during training. Similar to those of Foxx et al., our results indicated that all participants increased their use of the trained interactional behaviors during the generalization assessments in the presence of other trained peers.     

Prevalence and predictors of benevolent childhood experiences among a representative sample of young people

Emerging research evidence suggests that benevolent childhood experiences (BCEs) may partly explain more favourable mental health outcomes among individuals affected by adverse childhood experiences (ACEs). However, much of this research has focused on adult populations. Consequently, this study sought to provide the first rigorous assessment of the prevalence and predictors of BCEs using a nationally representative sample of young people from Northern Ireland (NI). Participants were 11–19-years-olds (N = 1293) who participated in the NI Youth Wellbeing Prevalence Survey (NI-YWS, 2020). Prevalence rates, gender differences and predictors of BCEs were investigated. Results revealed how most of the sample experienced multiple BCEs (95%, n = 1084), with females reporting higher levels of BCEs. Significant positive predictors of BCEs were female gender, parental education, living with both biological parents, and living in areas with lower deprivation, while significant negative predictors of BCEs included family being in receipt of social welfare and older age. Overall, this study highlights how BCEs are common, while the identification of factors associated with likelihood of having positive experiences during early development provides novel insights into those young people who may be at greater risk for maladaptive psychological outcomes.     

Relative validity of contextual and discrete cues

Contextual conditioning during relative validity training was explored in 3 experiments that used an appetitive Pavlovian conditioning preparation with rats. Magazine entries were the conditioned response. In Experiment 1, true-discrimination (TD: AX+, BX-) training generated weaker conditioning of X than did pseudodiscrimination (PD: AX+/-, BX+/-) training. The context showed a similar relative validity effect. Also, both PD training and simple partial reinforcement (X+/-) reduced contextual conditioning more than did unsignaled food, a demonstration of relative validity using partial reinforcement. Experiments 2 and 3 used within-subject and between-subjects designs, respectively, and showed that relative validity was determined by the summation of differences in conditioning to both the common element (X) and the context. Our results are consistent with an attentional model or with a computational comparator model but not with the Rescorla-Wagner (R. A. Rescorla & A. R. Wagner, 1972) model.
