Individual differences in eye-gaze measures of receptive vocabulary

This paper is currently under review. The study explores individual differences in receptive verb vocabulary in preschoolers with autism spectrum disorder (ASD). Children (N = 20, M(age) = 42 months, SD(age) = 10 months) participated in an eye-tracking task in which they saw referent actions depicted as dynamic scenes and were asked which depicted the target verb. Eye gaze measures were assessed in relation to scores on language assessments. Latency of the first look to the target scene correlated negatively with concurrent language ability. From an a priori response window, accuracy scores did not correlate with concurrent language abilities; however, given an individualized response window, accuracy did correlate positively with concurrent language. Results indicate that eye gaze can be used to assess receptive verb vocabulary given dynamic scene stimuli if individual differences are considered.

本文正处于审阅阶段。该研究旨在探讨自闭症谱系障碍（ASD）幼儿在接收动词词汇方面的个体差异。参与研究的儿童共计20名（平均年龄为42个月，年龄标准差为10个月），他们参与了一个眼动追踪任务，在任务中，他们观看了以动态场景描绘的参照动作，并被要求指出哪个场景描绘了目标动词。眼动测量数据与语言评估得分相关联。对目标场景的第一眼注视的潜伏期与同时期的语言能力呈负相关。在预设的响应时间窗口内，准确率得分与同时期的语言能力不相关；然而，在个性化的响应时间窗口内，准确率与同时期的语言能力呈正相关。研究结果指出，在考虑个体差异的情况下，可以通过动态场景刺激来利用眼动评估接收动词词汇。
