Abstract
This study examined the feasibility of eye tracking measures as markers of hyperphagia in 42 children and adults with Prader-Willi syndrome (PWS). Gaze data collected during free visual exploration of complex displays revealed that food images may not have an overall superior salience in PWS. However, increased attention to food in the context of other high-interest items was associated with higher scores on caregiver reports of hyperphagia. The study also provided preliminary evidence of test-retest reliability of eye tracking measures, suggesting that gaze characteristics may be a promising objective marker of food-related interests in PWS.
摘要
本研究调查了眼动追踪测量作为42名普拉德-威利综合征（PWS）儿童和成人暴饮暴食指标的可行性。在对复杂展示进行自由视觉探索期间收集的注视数据显示，食物图像在PWS中可能并不具有总体上更高的显著性。然而，在其他高兴趣物品的背景下对食物的关注度增加，与照顾者报告的暴饮暴食得分较高相关。该研究还提供了眼动追踪测量重测信度的初步证据，表明注视特征可能是PWS中与食物相关兴趣的一个有前景的客观指标。
