Classroom audience response systems, in which students respond to class questions via a remote ‘clicker’ unit, are widely used as a method for increasing student participation and providing immediate feedback in the form of a group frequency distribution. The phenomenon of social facilitation shows that task performance can be enhanced with co‐action of others or with the presence of an audience. To enhance the audience effect, we employed a unique feedback system that displays each individual's response. After reading a text passage, participants responded via a remote clicker to a series of comprehension questions. Participants were provided with no feedback regarding other respondents' answers, group feedback, or individual feedback. The results demonstrated significantly higher test performance with individual response identification. Implications are discussed in terms of applied classroom settings and social facilitation with enhanced options for displaying different types of feedback with clickers during instruction.

Repetitive self-injurious eye poking and stereotypic hand clapping were assessed in a child with autism and hearing impairment. A functional behavioral assessment conducted to identify the variables maintaining eye-poking behaviors indicated automatic reinforcement. Choice and environmental enrichment strategies were implemented to decrease the motivating operations associated with eye poking. Providing a choice of toys to hold in his hand led to the greatest reductions in both repetitive eye poking and hand clapping. Three follow-up observations were conducted 9 months after the intervention, which indicated that eye poking was eliminated and hand clapping was greatly reduced. This antecedent intervention was simple and effective, two hallmarks of sustainable behavior interventions. 相似文献

Cognitive–behavioural therapy (CBT) is an effective treatment for clinical and subclinical symptoms of depression and general anxiety, and increases life satisfaction. Patients’ usage of CBT skills is a core aspect of treatment but there is insufficient empirical evidence suggesting that skills usage behaviours are a mechanism of clinical change. This study investigated if an internet-delivered CBT (iCBT) intervention increased the frequency of CBT skills usage behaviours and if this statistically mediated reductions in symptoms and increased life satisfaction. A two-group randomised controlled trial was conducted comparing internet-delivered CBT (n = 65) with a waitlist control group (n = 75). Participants were individuals experiencing clinically significant symptoms of depression or general anxiety. Mixed-linear models analyses revealed that the treatment group reported a significantly higher frequency of skills usage, lower symptoms, and higher life satisfaction by the end of treatment compared with the control group. Results from bootstrapping mediation analyses revealed that the increased skills usage behaviours statistically mediated symptom reductions and increased life satisfaction. Although skills usage and symptom outcomes were assessed concurrently, these findings support the notion that iCBT increases the frequency of skills usage behaviours and suggest that this may be an important mechanism of change. 相似文献

Two experiments were performed to localize the site of binocular rivalry suppression in relation to the locus of grating adaptation. In one experiment it was found that phenomenal suppression of a high-contrast adaptation grating presented to one eye had no influence on the strength of the threshold-elevation aftereffect measured interocularly. Evidently information about the adaptation grating arrives at the site of the aftereffect (presumably binocular neurons) even during suppression. In a second experiment 60 s of grating adaptation was found to produce a short-term reduction in the predominance of the adapted eye during binocular rivalry. These findings provide converging lines of evidence that suppression occurs at a site in the human visual system after the locus of grating adaptation and, hence, after the striate cortex. 相似文献
