词汇语义通达受词汇的语音结构影响。不太清楚的是，这种效应是否是词汇形式和语义处理之间持续激活的结果，或者它们是否来自一个更加模块化的系统，在这个系统中，访问词汇形式的时间决定了语义激活的时间。本研究采用视觉世界范式，通过考察语义启动的时间进程与语音竞争者数量的关系来考察这一问题。关键试验包括高或低密度的听觉目标（如马）和视觉显示包含一个目标，一个语义相关的对象（如马鞍），和两个语音和语义无关的对象（如烟囱，比基尼）。结果表明，低密度词对语义相关目标的启动幅度大于高密度词，而高、低密度词对语义相关目标的启动在时间进程上无差异。这种模式的结果是一致的级联激活模型，预测词汇激活的语义激活的水平上有连续的影响，没有延迟的发病语义激活的语音竞争的话。
Lexical-semantic access is affected by the phonological structure of the lexicon. What is less clear is whether such effects are the result of continuous activation between lexical form and semantic processing, or whether they arise from a more modular system in which the timing of accessing lexical form determines the timing of semantic activation. This study examined this issue using the visual world paradigm by investigating the time course of semantic priming as a function of the number of phonological competitors. Critical trials consisted of high or low density auditory targets (e.g. horse) and a visual display containing a target, a semantically related object (e.g. saddle), and two phonologically and semantically unrelated objects (e.g. chimney, bikini). Results showed greater magnitude of priming for semantically related objects of low than of high density words and no differences for high and low density word targets in the time course of looks to the word semantically related to the target. This pattern of results is consistent with models of cascading activation, which predict that lexical activation has continuous effects on the level of semantic activation, with no delays in the onset of semantic activation for phonologically-competing words.
