Previous research indicates that vasopressin-containing (LE) rats are capable of adapting to the stress of food restriction,
whereas vasopressin-deficient (DI) rats cannot adapt to this stressor. It has been postulated that abnormalities in glucose
metabolism may be one of the factors leading to the demise of food-restricted DI rats. The present study was conducted to
determine if taste preferences are altered in DI animals and if the presentation of exogenous glucose, in the form of sucrose
solutions, can ameliorate the effects of the stress of food restriction. Four different concentrations of sucrose solutions
were presented to LE and DI rats under the food-restricted condition. In both strains, an 8% sucrose solution was preferred
over 0%, 16%, and 32% concentrations, with DI rats consuming more of this concentration than LE rats. Thus, when DI rats had
the opportunity of maintaining glucose homeostasis by exogenous supplements, they maintained body weight, displayed no stomach
pathology, and survived. 相似文献

Psychological research on the pupillary response since 1960 has focused on an arousal interpretation and a cognitive interpretation. Experiment 1 was an attempt to manipulate some arousal factors while controlling the cognitive demands of the task. Pupil size was cinematographically recorded while subjects who had different degrees of reported fear of snakes listened to passages describing imagined interactions with a snake in different proximities. There was also a set of control passages that made no mention of snakes but were otherwise semantically and syntactically identical to the aversive passages. The pupillary response showed no influence of the arousal manipulations, but rating and behavioral data indicated that the arousal variables had been effective. The cognitive demands of the task were clearly indicated by the pupillary response. In Experiment 2 two types of tasks were used: one that employed both arousal (incentive) and cognitive factors and another that had an arousal manipulation (threat of shock) but no explicit cognitive demands. The pupil response was recorded as well as heart rate, skin conductance, and EMG. The pupillary response showed an effect of the arousal manipulations only when cognitive demands were minimal. The results of both experiments are consistent with the view that cognitive demands take priority over arousal factors in affecting the pupillary response. Heart rate did show arousal effects that were not preempted by cognitive demands. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
