在口语理解过程中，听众会利用基于知识和基于信号的信息源，但人们对这些不同层次表征层次的线索如何在网上进行加权和整合却知之甚少。在使用视觉世界范式的眼球追踪实验中，我们研究了形态句法性别标记（基于知识的提示）和上下文语速（基于信号的提示）的灵活权重和整合。我们观察到，参与者立即使用形态句法提示来预测即将到来的指示物，即使提示的可靠性存在不确定性。此外，我们发现即使存在先前的形态句法信息，参与者的注视模式也会产生语速归一化效应。这些结果表明，线索是在线灵活加权和整合的，而不是遵循严格的层次结构。我们进一步发现，对形态句法性别线索表现出强烈行为偏好的参与者的观看行为存在率标准化效应。这表明速率标准化效应是稳健的并且可能是自动的。我们根据线索整合理论和声学背景效应的两阶段模型讨论这些结果。 （PsycINFO 数据库记录 (c) 2019 APA，保留所有权利）。
During spoken language comprehension, listeners make use of both knowledge-based and signal-based sources of information, but little is known about how cues from these distinct levels of representational hierarchy are weighted and integrated online. In an eye-tracking experiment using the visual world paradigm, we investigated the flexible weighting and integration of morphosyntactic gender marking (a knowledge-based cue) and contextual speech rate (a signal-based cue). We observed that participants used the morphosyntactic cue immediately to make predictions about upcoming referents, even in the presence of uncertainty about the cue's reliability. Moreover, we found speech rate normalization effects in participants' gaze patterns even in the presence of preceding morphosyntactic information. These results demonstrate that cues are weighted and integrated flexibly online, rather than adhering to a strict hierarchy. We further found rate normalization effects in the looking behavior of participants who showed a strong behavioral preference for the morphosyntactic gender cue. This indicates that rate normalization effects are robust and potentially automatic. We discuss these results in light of theories of cue integration and the two-stage model of acoustic context effects. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
