Although decades of research on functional analysis methodology have identified common contingencies that maintain problem behavior and effective interventions, relatively little research has been conducted on strategies to prevent the initial development of problem behavior. We conducted a 2‐part case study, the purposes of which were to illustrate the use of sensitivity tests as the bases for intervention (Study 1) and subsequently to assess the efficacy of a prevention strategy using a single‐subject design (Study 2). Results showed that the sensitivity tests identified establishing operations that may set the occasion for the development of problem behavior and that interventions based on differential reinforcement prevented increases in the severity of problem behavior relative to untreated and control baselines. Benefits and limitations to this individualized approach to prevention are discussed. 相似文献

Matrix training consists of planning instruction by arranging components of desired skills across 2 axes. After training with diagonal targets that each combine 2 unique skill components, responses to nondiagonal targets, consisting of novel combinations of the components, may emerge. A multiple‐probe design across participants was used to evaluate matrix training with known nouns (e.g., cat) and verbs (e.g., jumping) with 5 children with autism spectrum disorders (ASD). Following baseline of Matrix 1 and a generalization matrix, diagonal targets within Matrix 1 were trained as noun–verb combinations (e.g., cat jumping). Posttests showed recombinative generalization within Matrix 1 and the generalization matrix for 4 participants. For 1 participant, diagonal training across multiple matrices was provided until correct responding was observed in the generalization matrix. Results support the use of matrix training to promote untrained responses for learners with ASD and offer a systematic way to evaluate the extent of generalization within and across matrices. 相似文献

Reinforcers affect behavior. A fundamental assumption has been that reinforcers strengthen the behavior they follow, and that this strengthening may be context‐specific (stimulus control). Less frequently discussed, but just as evident, is the observation that reinforcers have discriminative properties that also guide behavior. We review findings from recent research that approaches choice using nontraditional procedures, with a particular focus on how choice is affected by reinforcers, by time since reinforcers, and by recent sequences of reinforcers. We also discuss how conclusions about these results are impacted by the choice of measurement level and display. Clearly, reinforcers as traditionally considered are conditionally phylogenetically important to animals. However, their effects on behavior may be solely discriminative, and contingent reinforcers may not strengthen behavior. Rather, phylogenetically important stimuli constitute a part of a correlated compound stimulus context consisting of stimuli arising from the organism, from behavior, and from physiologically detected environmental stimuli. Thus, the three‐term contingency may be seen, along with organismic state, as a correlation of stimuli. We suggest that organisms may be seen as natural stimulus‐correlation detectors so that behavioral change affects the overall correlation and directs the organism toward currently appetitive goals and away from potential aversive goals. As a general conclusion, both historical and recent choice research supports the idea that stimulus control, not reinforcer control, may be fundamental. 相似文献

This study investigated the effects of applying elements of the PETTLEP model on vividness and ease of imaging movement. Forty participants (M age = 23.47 years, SD = 4.11) completed the Vividness of Movement Imagery Questionnaire when using PETTLEP imagery or traditional imagery. Results revealed significantly higher ease and vividness ratings for internal visual imagery (IVI) and kinesthetic imagery (KI) during the PETTLEP imagery condition compared to the more traditional imagery. No significant difference between conditions for external visual imagery emerged. Findings imply that incorporating PETTLEP elements during imagery enables greater ease and vividness of movement when using IVI and KI. 相似文献

We report the case of a woman who pursued direct access genetic testing and then presented with concerns regarding a positive test result for Long-QT syndrome. Although the result ultimately proved to be a false positive, this case illustrates that costs associated with follow-up of direct access genetic testing results can be non-trivial for both the patient and for health care systems. Here we raise policy questions regarding the appropriate distribution of these costs. We also discuss the possibility that, when confronted by a direct access genetic test result that reports high risk for one or more actionable diseases, a family physician might feel compelled to act out of a desire to avoid liability, even when information regarding the accuracy and validity of the testing were not easily accessible. This case outlines lessons that can easily be translated into clinical practice, not only by genetic counselors, but also by family physicians, medical specialists and members of the public. 相似文献

Differences between Protestants and Catholics in religious beliefs and behavior are revisited in the light of growing theoretical and empirical evidence for stages of secularization and a remaining religious core in Western societies. To what extent are remaining Protestants more religious than before and compared with remaining Catholics? Analyzing repeated cross-sectional survey data from 1985 to 2012 in the US, Canada, and Great Britain, we find that, in most cases, Protestant affiliation has declined more significantly than Catholic affiliation. Yet, individuals who declare themselves as belonging to a Protestant denomination have higher rates of regular service attendance, prayer, and Christian beliefs than those previously. They have also surpassed these same rates among Catholics in both the US and Canada and are on track to do so in Britain in the coming years. 相似文献

Organizational change, although essential for business success, may negatively impact employees’ well-being. Based on person–environment fit theory, the authors investigate employees’ dispositional resistance to change as it impacts emotional exhaustion. Furthermore, the authors examine boundary conditions that may affect dispositional resistance to change and its influence on emotional exhaustion. They take a trait activation approach and test the moderating roles of two work-unit-level internal contextual factors: perceived organizational support and informational team climate. Using a longitudinal research design of 709 participants in 30 work units, multilevel analyses reveal that dispositional resistance to change (time 1) is positively related to emotional exhaustion (time 2). Moreover, a lack of perceived organizational support and a high informational team climate strengthen these effects. The authors conclude that organizations should offer coaching and training programmes to cope with organizational change for employees who are highly change resistant. Furthermore, personal and organizational development strategies should consider the insights gained from the study regarding internal contextual factors that moderate change management processes. 相似文献

Research on early false belief understanding has entirely relied on affect‐neutral measures such as judgments (standard tasks), attentional allocation (looking duration, preferential looking, anticipatory looking), or active intervention. We used a novel, affective measure to test whether preschoolers affectively anticipate another's misguided acts. In two experiments, 3‐year‐olds showed more expressions of suspense (by, e.g. brow furrowing or lip biting) when they saw an agent approach a scene with a false as opposed to a true belief (Experiment 1) or ignorance (Experiment 2). This shows that the children anticipated the agent's surprise and disappointment when encountering reality. The findings suggest that early implicit knowledge of false beliefs includes anticipations of the affective implications of erring. This vital dimension of beliefs should no longer be ignored in research on early theory of mind. 相似文献
