During sentence comprehension, real-time identification of a referent is driven both by local, context-independent lexical information and by more global sentential information related to the meaning of the utterance as a whole. This paper investigates the cognitive factors that limit the consideration of referents that are supported by local lexical information but not supported by more global sentential information. In an eye-tracking paradigm, participants heard sentences like "She will eat the red pear" while viewing four black-and-white (colorless) line-drawings. In the experimental condition, the display contained a "local attractor" (e.g., a heart), which was locally compatible with the adjective but incompatible with the context ("eat"). In the control condition, the local attractor was replaced by a picture which was incompatible with the adjective (e.g., "igloo"). A second factor manipulated contextual constraint, by using either a constraining verb (e.g., "eat"), or a non-constraining one (e.g., "see"). Results showed consideration of the local attractor, the magnitude of which was modulated by verb constraint, but also by each subject's cognitive control abilities, as measured in a separate Flanker task run on the same subjects. The findings are compatible with a processing model in which the interplay between local attraction, context, and domain-general control mechanisms determines the consideration of possible referents.
在句子理解过程中,指称对象的实时识别既受局部的、与上下文无关的词汇信息驱动,也受与整个话语意义相关的更全局的句子信息驱动。本文研究了一些认知因素,这些因素限制了对由局部词汇信息支持但不受更全局句子信息支持的指称对象的考虑。在一个眼动追踪范式中,参与者在观看四幅黑白(无色)线条画时听到诸如“她将吃那个红色的梨”这样的句子。在实验条件下,展示画面包含一个“局部吸引物”(例如一颗心),它在局部与形容词相符,但与上下文(“吃”)不相符。在控制条件下,局部吸引物被一幅与形容词不相符的图片(例如“冰屋”)所取代。第二个因素通过使用一个有约束性的动词(例如“吃”)或一个无约束性的动词(例如“看”)来操纵上下文约束。结果显示了对局部吸引物的考虑,其程度不仅受动词约束的调节,还受每个受试者认知控制能力的调节,这种能力是在对同一受试者进行的单独的侧翼任务中测量的。这些发现与一个处理模型相符,在该模型中,局部吸引、上下文和领域通用控制机制之间的相互作用决定了对可能指称对象的考虑。
