In an eye-tracking during reading experiment we investigated the processing of ambiguous Polish imperfective verbs in contexts with disambiguating (‘frequently’ and ‘yesterday’) and neutral preceding adverbs. Grammatical number of NP objects was also manipulated. Verb regions received significantly longer regression path times when following a neutral compared to 'yesterday' contexts. This implies that in neutral contexts both senses of polysemous imperfective verbs are activated on the verbal region. Post-hoc analyses revealed more regressions from singular objects in neutral contexts, suggesting that a preference for a more frequent plural event sense was created before the first fixations on the object were made. Finally, we observed an effect consisting of longer first pass times on singular objects and more regressions from the following region in contexts with ‘frequently’, which is consistent with the view that imperfective aspect is underspecified for number. This pattern of results is compatible with Relevance Theory, which posits that the selection of one sense (single ongoing or plural) is an outcome of an inferential process based on frequency, context and world knowledge. However, the fact that sense frequency plays a role in this process indicates that it serves as input to context-based inferential processes suggesting that this information is pre-stored in the memory.

未指定数量的不完美方面：来自阅读实验期间眼动追踪的证据

在阅读实验中的眼动追踪中，我们研究了在具有消歧义（“经常”和“昨天”）和中性前置副词的上下文中歧义波兰语未完成动词的处理。NP 对象的语法数量也被操纵。与“昨天”的语境相比，在遵循中性语境时，动词区域会收到明显更长的回归路径时间。这意味着在中性语境中，多义未完成动词的两种意义都在言语区域被激活。事后分析显示，在中性语境中，单一对象的回归更多，这表明在对对象进行第一次注视之前，就已经产生了对更频繁的复数事件感的偏好。最后，我们观察到一种效果，包括在“经常”的上下文中，单个对象的首次通过时间更长，并且从以下区域回归更多，这与不完美方面未指定数量的观点一致。这种结果模式与关联理论相一致，关联理论认为选择一种意义（单义或复义）是基于频率、语境和世界知识的推理过程的结果。然而，感觉频率在这个过程中发挥作用的事实表明它作为基于上下文的推理过程的输入，表明该信息预先存储在记忆中。这种结果模式与关联理论相一致，关联理论认为选择一种意义（单义或复义）是基于频率、语境和世界知识的推理过程的结果。然而，感觉频率在这个过程中发挥作用的事实表明它作为基于上下文的推理过程的输入，表明该信息预先存储在记忆中。这种结果模式与关联理论相一致，关联理论认为选择一种意义（单义或复义）是基于频率、语境和世界知识的推理过程的结果。然而，感觉频率在这个过程中发挥作用的事实表明它作为基于上下文的推理过程的输入，表明该信息预先存储在记忆中。
