接受性词汇的视觉注意测量对参与者的任务要求最小,并且产生比家长报告更准确的语言理解测量。然而,目前基于注视的测量方法采用的视觉比较仅限于两个同时发生的项目。由于这种限制,目标与干扰物的相似程度会对任务表现的解释产生重大影响。目前的研究评估了一种新的基于凝视的范式,其中包括一个8项数组。这个视觉阵列任务(VAT)结合了多式联运优先观看范式的理论框架和边听边看的语言理解测量方法,但使用了更多的同时呈现的项目。使用更大的项目数组和包含上级类别对比可以提供更敏感的接受性词汇测量,以及对早期单词理解反映更广泛类别知识的程度的理解。结果表明,测试增值税是一个敏感的测量对象标签和类别知识。这种范式为研究人员提供了一种灵活有效的任务来测量语言理解和类别知识,同时减少了对参与者的行为要求。
Visual attention measures of receptive vocabulary place minimal task demands on participants and produce a more accurate measure of language comprehension than parent report measures. However, current gaze-based measures employ visual comparisons limited to two simultaneous items. With this limitation, the degree of similarity of the target to the distractor can have a significant impact on the interpretation of task performance. The current study evaluates a novel gaze-based paradigm that includes an eight-item array. This Visual Array Task (VAT) combines the theoretical frameworks of the Intermodal Preferential Looking Paradigm and looking-while-listening methods of language comprehension measurement but using a larger array of simultaneously presented items. The use of a larger array of items and the inclusion of a superordinate category contrast may provide a more sensitive measure of receptive vocabulary as well as an understanding of the extent to which early word comprehension reflects knowledge of broader categories. Results indicated that the tested VAT was a sensitive measure of both object label and category knowledge. This paradigm provides researchers with a flexible and efficient task to measure language comprehension and category knowledge while reducing behavioral demands placed on participants.
