Food selectivity is a common problem for children with autism spectrum disorder (ASD; Schreck, Williams, & Smith, 2004). Behavior‐analytic interventions have the most empirical support for feeding disorders (Sharp, Jaquess, Morton, & Miles, 2011). However, there are no randomized controlled trials that have evaluated its effects with a well‐defined cohort of children with ASD. In the current investigation, we randomly assigned 6 young children with ASD and food selectivity to either an applied behavior analytic intervention or a wait‐list control. We used a crossover randomized controlled trial to evaluate the effects of a multicomponent applied behavior analytic intervention on independent acceptance and mouth clean of 16 novel foods. We subsequently exposed the wait‐list control group to the intervention. We also evaluated the effects of the intervention on individual participants with single‐case designs. The percentage of independent acceptance and mouth clean increased for the applied behavior analytic intervention group, but not for the wait‐list control group until we implemented the intervention. 相似文献

Under naturally occurring conditions, the individual who is the target of aggression is likely to physically react to evade the aggressor and avoid physical harm. Like other forms of attention that occur following problem behavior, physical reactions may maintain problem behavior. However, evaluating the effects of physical reactions is complicated by issues related to therapists' ability to consistently and safely control their reactions, which may prove difficult to achieve in functional analyses. We evaluated the utility of a concurrent‐operant analysis to test behavioral sensitivity to physical reactions. The results suggest that the concurrent‐operant analysis may be useful when therapists cannot consistently refrain from responding contingent on problem behavior in the control condition of a more typical functional analysis. 相似文献

In this study, we examined perceptions of the citizenship behaviors of male and female employees who took leave to care for a newborn, a sick child, a sick parent, or who did not take leave. In a 2 (employee gender) × 4 (reason for leave) × 2 (participant gender) experimental design, 242 undergraduate students read a mock personnel file and rated the employee on altruism and generalized compliance. Female employees were not rated differently whether they took leave or not. Male employees who took leave for birth or eldercare were rated less likely to be altruistic at work than their male counterparts who did not take leave and their female counterparts who took leave. There was also a bias against male leave takers for generalized compliance ratings, especially by male evaluators. Future research ideas and implications for organizational practice are discussed. 相似文献

Based on cognitive load theory, two experiments investigated the conditions under which audiovisual‐based instruction may be an effective or an ineffective instructional technique. Results from Experiment 1 indicated that visual with audio presentations were superior to equivalent visual‐only presentations. In this experiment, neither the auditory nor the visual material could be understood in isolation. Both sources of information were interrelated and were essential to render the material intelligible. In contrast, Experiment 2 demonstrated that a non‐essential explanatory text, presented aurally with similar written text contained in a diagram, hindered learning. This result was obtained because when compared to a diagram only format, the aural material was unnecessary and therefore created a redundancy effect. Differences between groups were stronger when information was high in complexity. It was concluded that the effectiveness of multimedia instruction depends very much on how and when auditory information is used. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

Discontinuation of the contingency between a response and its reinforcer sometimes produces a temporary increase in the response before its rate decreases, a phenomenon called the extinction burst. Prior clinical and basic studies on the prevalence of the extinction burst provide highly disparate estimates. Existing theories on the extinction burst fail to account for the dynamic nature of this phenomenon, and the basic behavioral processes that control response bursting remain poorly understood. In this paper, we first review the basic and applied literature on the extinction burst. We then describe a recent refinement of the concatenated matching law called the temporally weighted matching law that appears to resolve the above-mentioned issues regarding the extinction burst. We present illustrative translational data based conceptually on the model. Finally, we discuss specific recommendations derived from the temporally weighted matching law regarding procedures clinicians could implement to potentially mitigate or prevent extinction bursts. 相似文献

There are good reasons for pursuing a theory of knowledge by way of understanding the connection between knowledge and luck. Not surprisingly, then, there has been a burgeoning of interest in “luck theories” of knowledge as well as in theories of luck in general. Unfortunately, “luck” proves to be as recalcitrant an analysandum as “knows.” While it is well worth pursuing a general theory of luck despite these difficulties, our theory of knowledge might be made more manageable if we could find a more restricted notion that captured the core phenomena of luck that are relevant to whether or not someone knows. This essay makes the attempt to delineate such a notion, called “mere coincidence.” 相似文献

I critically examine Cappelen and Lepore’s definition of and tests for indexicality, and refine them to improve their adequacy. Indexicals cannot be defined as expressions with different referents in different contexts unless linguistic meaning and circumstances of evaluation are held constant. I show that despite Cappelen and Lepore’s claim that there are only a handful of indexical expressions, their “basic set” includes a number of large and open classes, and generates an infinity of indexical phrases. And while the tests can be used effectively to combat contextualism concerning ‘knows’ and ‘actual,’ many expressions not in their basic set test positive for indexicality, including quantifier nouns, weather reports, and comparative adjectives. I rebut their claim that context-shifting arguments inevitably lead to radical contextualism, and that if there were any indexicals beyond their basic set, communication would be impossible. 相似文献
