Television comprehension is a surprisingly demanding task for very young children. Based on a task analysis of television viewing and review of research, we suggest that by 6 months of age, infants can identify objects and people on screen. By 24 months they can comprehend and imitate simple actions contained in single shots and begin to integrate information across shots. Toddlers nevertheless suffer from the video deficit whereby their comprehension is less than from equivalent real life displays. During the preschool years they learn much of the grammar of filmic montage and can comprehend straightforward narrative productions. Essentially adult comprehension appears to be in place by 13 years of age.  相似文献

We compared two procedures for improving the social interactions of three autistic children. In a peer-initiation condition, confederates were taught to initiate interaction with the autistic children. In a teacher-antecedent condition, teachers prompted the autistic children to initiate with confederates, who had been taught to reciprocate. Using an alternating treatment design, differential effects were found. The peer-initiation procedure reliably increased the social responses of the autistic children, whereas the teacher-antecedent condition increased the initiations and responses of the autistic children. In addition, longer chains of social interaction occurred during the teacher-antecedent condition.  相似文献

Inclusive instruction was provided for three older adults with profound mental retardation in a water exercise class at a local YMCA. The older adults were taught to exercise through the use of systematic prompting. A multiple baseline design across participants with an embedded reversal was used to evaluate the impact of a personal trainer. The three participants performed the exercise, but regressed without the assistance of the trainer, as demonstrated by the reversal. Data collected during peer prompting and maintenance conditions indicated that the participants continued to exercise at levels higher than baseline but lower than with a personal trainer.  相似文献

On a ward for 24 psychogeriatric patients, 18 were randomly assigned to three groups with different experimental conditions. The first group was prompted and reinforced for different activities; the second was only prompted; and the third served as a control group. Activities, both the trained ones and others, were continuously monitored throughout the five week study. The results showed a clear increase in the trained activities after training. The prompting condition was effective, and the addition of reinforcement did not add any to the effects. There was no generalization to untrained activities, and the effects did not last at the 1 hr or 21 hr assessments, but was clearly visible at 5 min after training. Time seemed to be more important than place, i.e. the effect ceased with elapsed time, not because of changes in the situation.  相似文献

The effects of automated cueing on teacher praise rate was investigated in one special, one fourth-, and one seventh-grade classroom. After establishing baseline praise rates in each of the three classrooms, two methods for increasing teacher praise rate were introduced according to a multiple-baseline design. During the first phase, two teachers were instructed to count and graph their praise rate during each session. All teachers received auditory cues to prompt praising during another phase. In all cases, introduction of cues markedly increased teacher praise rates, but self-recording was relatively ineffective. An analysis of teacher-praise distributions showed that cues closely controlled teacher praise for two of the three teachers.  相似文献

The seat belt usage of drivers was observed at the entrance to two campus parking lots during morning arrival times. After 11 days of baseline, fliers which prompted seat belt wearing were handed to drivers of incoming vehicles. At one parking lot all fliers offered a chance to win a prize (noncontingent rewards); while at the second lot only those fliers given to seat belt wearers included a chance to win a prize (contingent rewards). After 24 consecutive observation days, these interventions were removed for 14 days of withdrawal. The recording of vehicle license plates enabled an analysis of belt usage per individual over repeated exposures to the experimental conditions. At the lot with the contingent reward intervention, mean belt usage was 26.3% during baseline, 45.7% during treatment, and 37.9% during withdrawal. At the noncontingent reward lot, the mean percentage of belt wearing was 22.2% during baseline, 24.1% during treatment, and 21.8% during withdrawal. The analysis of repeated exposures per individual verified that only contingent rewards influenced substantial increases in belt wearing, and showed that most of the influence occurred after the initial incentive prompt.  相似文献

A community-based strategy for promoting safety belt use was field-tested in two adjacent rural communities, one populated by a preponderance of students, faculty, and staff of a major university. The intervention involved the front-seat passenger of a stopped vehicle displaying to the driver of an adjacent, stopped vehicle an 11 x 14 inch flash card that read, "PLEASE BUCKLE UP-I CARE." If the driver buckled up, the "flasher" flipped over the card and displayed the message, "THANK YOU." This flash card was shown to 1,087 unbuckled drivers; 82% of these drivers looked at the flash card and 22% of these complied with the buckle-up request. Compliance was not influenced by the age or gender of the "flasher" (young child vs. college student), nor by the gender of the driver; but significantly more drivers in the university town buckled up following the flash card presentation (25% mean compliance in the college town vs. 14% in the other community). To date, over 2,000 individuals have received a buckle-up flash card for their own use.  相似文献

Video summarization is one of the key techniques to access and manage a huge chunk of videos. Video summarization is used to extract the effective contents of a video sequence to generate a concise representation of its content. The involvement of crowdsourcing models in recent years is effectively used by researchers in E-commerce domain to increase the quality of the data contents. In this paper, we present a video summarization framework based on users emotion while they watch videos by analyzing cerebral activities through Electroencephalogram (EEG) signals. Three emotions, namely happy, sad and neutral have been extracted from the EEG signals. Video frames have been synchronized with EEG signals and tagged with various emotions. Finally, a crowdsourcing model has been used for effective summarization of the videos. The qualitative assessment of video summarization has been conducted with the help of user ratings using online Google Forms application. EEG signals of 28 users have been recorded while video streams of different emotions. An average accuracy of 83.93% has been recorded in emotion classification using crowdsourcing. Output summarized videos include dynamic video skims and the corresponding audio stream for better understanding.  相似文献
