Researchers have recently begun to evaluate video-based preference assessments; however, only two studies have evaluated the efficacy of this preference assessment modality in assessing preference for social interactions. Four individuals diagnosed with autism spectrum disorder who could not match pictures or graphic-interchange-format images (GIFs) of social interactions to in vivo interaction participated. We compared picture and GIF-based paired-stimulus preference assessments for social interaction and evaluated the preference assessment hierarchies by conducting a concurrent-operant reinforcer assessment including all social interactions. The GIF-based preference assessment produced similar hierarchies to the reinforcer assessment for all participants, whereas the picture-based preference assessments produced similar hierarchies to the reinforcer assessment for 2 of 4 subjects. Additionally, we conducted a modality preference assessment in which we evaluated participants' preference for viewing GIFs or pictures of social interactions, and found that 3 out of 4 subjects displayed a preference for GIFs.
研究人员最近开始评估基于视频的偏好评估；然而，只有两项研究评估了这种偏好评估模式在评估社交互动偏好方面的效果。四名被诊断患有自闭症谱系障碍的人无法将社交互动的图片或图形交换格式图像 (GIF) 与实际互动匹配，参与了研究。我们比较了基于图片和 GIF 的社交互动配对刺激偏好评估，并通过进行包括所有社交互动的同时操作性强化评估来评估偏好评估层次结构。对于所有参与者，基于 GIF 的偏好评估产生的层次结构与强化评估相似，而对于 4 名参与者中的 2 名，基于图片的偏好评估产生的层次结构与强化评估相似。此外，我们进行了一种模态偏好评估，评估了参与者对观看社交互动的 GIF 或图片的偏好，发现 4 名参与者中有 3 名更喜欢 GIF。
