The purpose of this study was to evaluate the effects of video modeling - in the home setting - on food selectivity of three children with an autism spectrum disorder. Using a multiple baseline experimental design, the researcher implemented an in home video modeling intervention during dinner for all three participants. Intervention consisted of a video modeling condition, a video modeling plus reinforcement condition, and follow-up probes conducted for five months after the departure of the researcher. The video modeling alone resulted in an increased acceptance of food by participants. When reinforcement was added to the video modeling, a higher level of food acceptance occurred for all three participants. The results suggest that video modeling was effective in increasing food acceptance, but food acceptance was higher for all three participants when reinforcement was added. Follow-up probes conducted for five months after the departure of the researcher suggest that the video modeling intervention was responsible for the increased food acceptance.
本研究旨在评估家庭环境中的视频建模对三名自闭症谱系障碍儿童食物选择性的影响。采用多项基线实验设计，研究人员在所有三名参与者的晚餐期间实施了家庭视频建模干预。干预包括视频建模条件、视频建模加强化条件以及研究人员离开后的五个月进行的后续探测。单独的视频建模导致参与者对食物的接受度增加。当强化被添加到视频建模中时，所有三名参与者的食物接受度都更高。结果表明，视频建模在增加食物接受度方面是有效的，但当强化被添加时，所有三名参与者的食物接受度都更高。研究人员离开后的五个月进行的后续探测表明，视频建模干预是导致食物接受度增加的原因。
