孤独症儿童假装游戏技能的干预研究——以玩偶为中介的虚构客体游戏为例     

刘艳虹  任媛  胡晓毅 《中国特殊教育》2021,(3):33-38,45

本研究采用单一被试研究中的跨行为多探测设计,以成人与同伴混合视频示范作为干预策略,嵌入动机操作的原理,对一名孤独症儿童实施以玩偶为中介的虚构客体游戏行为的干预。研究结果显示:孤独症儿童在干预期的目标游戏中表现出的与视频脚本一致的假装游戏行为数量显著增加,并能够得到良好的维持;在未经教学的游戏情境中能够表现出恰当的虚构客体游戏行为,表明儿童习得的虚构客体游戏技能能够得到良好的泛化。  相似文献   

Segmenting the audience of a cause-related marketing viral campaign     

《International Journal of Information Management》2021

This paper analyses the attitudinal effect of a cause-related marketing campaign which becomes viral through social networks. This attitudinal response is observed in three Internet user segments with different affinity levels: i) strong (familiar with the sponsoring brand and the promoted cause); ii) intermediate (familiar with the brand or the cause); and iii) weak (without previous experiences of either the brand or the social cause). To develop our experiment, 360 Internet surfers agree to participate. Their attitudes were measured before and after the showing of a viral spot in which a pet food brand encourages pet adoption. Our results show that a viral campaign works perfectly for the strong-affinity segment and adequately for the week affinity segment. On the contrary, this viral campaign leaves the intermediate-affinity segment indifferent.  相似文献

Using iPad tablets for self‐modeling with preschoolers: Videos versus photos          下载免费PDF全文

Dacia M. McCoy  Julie Q. Morrison  Dave W. Barnett  Hilary D. Kalra  Lauren K. Donovan 《Psychology in the schools》2017,54(8):821-836

As technology becomes more accessible and acceptable in the preschool setting, teachers need effective strategies of incorporating it to address challenging behaviors. A nonconcurrent delayed multiple baseline design in combination with an alternating treatment design was utilized to investigate the effects of using iPad tablets to display video self‐modeling and activity photos for three preschoolers during circle time. During baseline, all three children demonstrated low levels of engagement and high levels of off‐task behavior compared to peers. The intervention phase consisted of alternating between showing the child the self‐video and photos prior to circle time. A child preference phase was conducted whereby each child self‐selected the video or photo prior to circle time. For all three children both videos and photos led to increased engagement and decreased off‐task behaviors. During the child preference phase, all three children selected the video most frequently. Social validity data demonstrated teacher and child preference for the video self‐modeling condition.  相似文献   

What if best practice is too expensive? Feedback on oral presentations and efficient use of resources     

Lawrence A. Leger  Karligash Glass  Paraskevi Katsiampa  Shibo Liu  Kavita Sirichand 《Assessment & Evaluation in Higher Education》2017,42(3):329-346

We evaluate feedback methods for oral presentations used in training non-quantitative research skills (literature review and various associated tasks). Training is provided through a credit-bearing module taught to MSc students of banking, economics and finance in the UK. Monitoring oral presentations and providing ‘best practice’ feedback is very resource-intensive. Do we withdraw oral presentations from the module, because best feedback practice is prohibitively expensive in a world of limited resources, or choose a second-best alternative? To what extent might the latter compromise intended learning outcomes? We used the same provision of video feedback for all students but used two verbal feedback regimes. For one regime, we decreased the amount of verbal feedback and increased the number of presentations. The impact was measured by academic outcome, rating scales and questionnaire. Overall satisfaction with the module was very high for both feedback regimes, and there were no statistically significant differences between regimes, suggesting that less resource-intensive methods need not compromise learning outcomes.  相似文献   

Review of The Atlas of Erotic Anatomy and Arousal     

Lorena Olvera Moreno 《American journal of sexuality education》2017,12(3):337-341

The Atlas of Erotic Anatomy and Arousal is online video education that explores sexual pleasure and sexual anatomy from a sex positive perspective. Written and presented by a sex educator and therapist, Cyndi Darnell, this video is an excellent resource for adult individuals interested in learning about their bodies and having fulfilling sexual experiences with their partners. The video series provides scientifically accurate and pleasure-based information about the anatomy of the vulva, the penis, and the anus, and the physiology of orgasm and ejaculation, in an entertaining manner.  相似文献
