The effect of language-driven eye movements in a visual scene with concurrent speech was examined using complex linguistic stimuli and complex scenes. The processing demands were manipulated using speech rate and the temporal distance between mentioned objects. This experiment differs from previous research by using complex photographic scenes, three-sentence utterances and mentioning four target objects. The main finding was that objects that are more slowly mentioned, more evenly placed and isolated in the speech stream are more likely to be fixated after having been mentioned and are fixated faster. Surprisingly, even objects mentioned in the most demanding conditions still show an effect of language-driven eye-movements. This supports research using concurrent speech and visual scenes, and shows that the behavior of matching visual and linguistic information is likely to generalize to language situations of high information load.
使用复杂的语言刺激和复杂场景,研究了在伴有同步语音的视觉场景中语言驱动的眼动效应。通过语速和所提及对象之间的时间距离来操纵加工需求。本实验与以往研究的不同之处在于使用了复杂的照片场景、三句话的话语以及提及四个目标对象。主要发现是,在语音流中提及速度较慢、分布更均匀且孤立的对象,在被提及后更有可能被注视,并且注视速度更快。令人惊讶的是,即使在要求最高的条件下提及的对象,仍然显示出语言驱动眼动的效应。这支持了使用同步语音和视觉场景的研究,并表明匹配视觉和语言信息的行为可能会推广到高信息负荷的语言情境中。
