Individuals with disabilities often demonstrate difficulty in social communication skills such as greetings. Studies have shown that deficits in greetings may negatively affect social interactions and vocational opportunities. Therefore, previous research has evaluated a variety of teaching procedures to increase greetings for individuals with disabilities with varying efficacy. This review of the literature provides an overview of studies to date in which greetings were taught to individuals with intellectual disabilities. A variety of teaching procedures were identified, and implications of those procedures are discussed. Results suggest that multiple teaching procedures may be effective; however, component analyses, further replication, and modified generalization procedures are necessary. Implications for future researchers include identifying a technological definition of greetings and evaluating effective teaching procedures and generalization strategies. Implications for practitioners include teaching one greeting type at a time, limiting the number of social skills taught simultaneously, identification of effective teaching procedures and generalization considerations. 相似文献

A review of the literature pertaining to Rokeach, Smith, and Evans' (1960) belief congruence theory provided a context for discussion of some methodological and theoretical issues relating to conceptualization of the dependent variables, beliefcontent, belief discrepancy, meaningfulness of the race—belief comparison, attitude—belief feedback loops, attitude structure, and the relation between self and ideal similarity. The literature was judged supportive of a weak version of belief congruence theory which states that in those contexts in which social pressure is nonexistent or ineffective, belief is more important than race as a determinant of racial or ethnic discrimination. Evidence for a strong version of belief congruence theory (which states that in those contexts in which social pressure is nonexistent, or ineffective, belief is the only determinant of racial or ethnic discrimination) and was judged much more problematic. 相似文献

The action-based model of dissonance predicts that following decisional commitment, approach-oriented motivational processes occur to assist in translating the decision into effective and unconflicted behavior. Therefore, the modulation of these approach-oriented processes should affect the degree to which individuals change their attitudes to be more consistent with the decisional commitment (spreading of alternatives). Experiment 1 demonstrated that a neurofeedback-induced decrease in relative left frontal cortical activation, which has been implicated in approach motivational processes, caused a reduction in spreading of alternatives. Experiment 2 manipulated an action-oriented mindset following a decision and demonstrated that the action-oriented mindset caused increased activation in the left frontal cortical region as well as increased spreading of alternatives. Discussion focuses on how this integration of neuroscience and dissonance theory benefits both parent literatures. 相似文献

Listeners are exquisitely sensitive to fine-grained acoustic detail within phonetic categories for sounds and words. Here we show that this sensitivity is optimal given the probabilistic nature of speech cues. We manipulated the probability distribution of one probabilistic cue, voice onset time (VOT), which differentiates word initial labial stops in English (e.g., "beach" and "peach"). Participants categorized words from distributions of VOT with wide or narrow variances. Uncertainty about word identity was measured by four-alternative forced-choice judgments and by the probability of looks to pictures. Both measures closely reflected the posterior probability of the word given the likelihood distributions of VOT, suggesting that listeners are sensitive to these distributions. 相似文献

Speech perception requires listeners to integrate multiple cues that each contribute to judgments about a phonetic category.
Classic studies of trading relations assessed the weights attached to each cue but did not explore the time course of cue
integration. Here, we provide the first direct evidence that asynchronous cues to voicing (/b/ vs. /p/) and manner (/b/ vs.
/w/) contrasts become available to the listener at different times during spoken word recognition. Using the visual world
paradigm, we show that the probability of eye movements to pictures of target and of competitor objects diverge at different
points in time after the onset of the target word. These points of divergence correspond to the availability of early (voice
onset time or formant transition slope) and late (vowel length) cues to voicing and manner contrasts. These results support
a model of cue integration in which phonetic cues are used for lexical access as soon as they are available. 相似文献

Attrition is a common problem in weight loss trials. The present analysis examined several baseline and early-treatment process variables, as predictors of attrition and outcome in a clinical trial that combined pharmacotherapy and behavior therapy for weight loss. Participants were 224 obese adults who were treated with sibutramine alone, lifestyle modification alone, combined therapy, or sibutramine plus brief lifestyle modification. Predictors included baseline characteristics (e.g., demographic, weight-related, psychological, and consumption-related variables), plus attendance, adherence, and weight loss in the early weeks of treatment. Outcomes were attrition and weight loss success (i.e., ≥5% reduction in body weight) at 1 year. Multivariable models, adjusting for other relevant variables, found that younger age and greater baseline depressive symptoms were related to increased odds of attrition (ps ≤ 0.003). Greater early weight loss marginally reduced the odds of attrition (p = 0.06). Predictors of weight loss success at 1 year were Caucasian ethnicity (p = 0.04), lower baseline depressive symptoms (p = 0.04), and weight loss during the first 3 weeks of treatment (p < 0.001). Thus, depressive symptoms at baseline were a significant predictor of both attrition and weight loss success. As a process variable, early weight loss appears to have more predictive value than early attendance at treatment sessions or early adherence. 相似文献

Innovative approaches are urgently needed to improve behavioral treatment for weight loss. The weight regain that is so common after treatment may be a result of an environment that makes it challenging to adhere, long-term, to a dietary and physical activity regimen. This study was designed to test, via a 12-week open trial, the preliminary feasibility, acceptability, effectiveness, and possible mechanisms of action of a behavioral treatment that was modified to incorporate acceptance-based therapy components designed to (a) bolster participants’ commitment to behavior change, (b) build distress-tolerance skills, and (c) promote mindful awareness of eating behaviors and goals. Participants (n = 29) were overweight or obese women. Among completers (n = 19; 34% attrition), weight loss averaged 6.6% of body weight at posttreatment and 9.6% at 6-month follow-up (n = 14; 52% attrition). Intention-to-treat weight losses were 4.5% at posttreatment and 6.6% at 6-month follow-up. Psychological variables targeted by the intervention (e.g., cognitive restraint, disinhibition, urge-related eating behavior, emotional eating, eating-related experiential acceptance, mindfulness and motivation) changed in the expected directions, and many of these changes were consistent with decreases in weight loss. Moreover, despite the limitations of the single-group design, this pilot study demonstrated the preliminary feasibility, acceptability, and effectiveness of a novel, acceptance-based behavioral treatment for obesity. One potential implication is that behaviorally based weight loss interventions might be improved by overlaying an acceptance-based framework. 相似文献
