The purpose of this study was to examine whether duration of eye gaze could be used to identify reinforcing stimuli for four individuals with severe physical and developmental disabilities, as well as the effectiveness of the assessment using different numbers of stimuli (i.e. 6 vs 14).
This study measured each student's preferences in a paired stimulus preference assessment using duration of eye gaze toward various stimuli. Following the preference assessment, a reinforcer assessment was conducted within a reversal design to determine the accuracy of the preference hierarchy.
Results indicated that duration of eye gaze toward a stimulus was successful in identifying preferred stimuli that functioned as reinforcers for all participants. Additionally, the shorter preference assessment produced measures of similar accuracy in considerably less time.
Eye gaze can be used to identify reinforcing stimuli for individuals with severe physical and developmental disabilities.
本研究旨在探讨注视时长是否可用于识别四名重度身体和发育残疾个体的强化刺激，以及使用不同数量刺激（即6个与14个）进行评估的有效性。
本研究在配对刺激偏好评估中，通过对各种刺激的注视时长来测量每个学生的偏好。在偏好评估之后，采用反转设计进行强化物评估，以确定偏好等级的准确性。
结果表明，对刺激的注视时长成功识别出了对所有参与者都起强化作用的偏好刺激。此外，较短的偏好评估在更短的时间内产生了准确性相似的测量结果。
