通过5个跨通道图词干扰实验，考察了言语产生过程中词汇化的时间进程。参与者在不同的刺激起始时间（SOA）听到干扰词时命名简单物体的图片。干扰词与图片名称或其非目标近义词在语义上或语音上相关。与不相关的对照组相比，所有分心物的影响在晚SOA（150毫秒），并在此后不久消失（SOA = 300毫秒）。这些发现与早期选择单一元素的概念相冲突。相反，多个词汇表征似乎保持活跃，直到后期的生产过程中，如果一个接近同义的词汇竞争对手。作者讨论了这些观察的范围和它们的相关性离散两阶段和级联模型的词汇访问。
In 5 cross-modal picture-word interference experiments, the authors investigated the time course of lexicalization in speech production. Participants named pictures of simple objects while hearing distracter words at different stimulus-onset asynchronies (SOAs). Distracters were semantically related or phonologically related to either the picture name or its nontarget near-synonym. Compared with an unrelated control, effects from all distracters were obtained at a late SOA (150 ms) and vanished shortly thereafter (at SOA = 300 ms). These findings conflict with the notion of an early selection of a single element. Rather, multiple lexical representations appear to remain active until late in the production process if a near-synonymous lexical competitor is present. The authors discuss the scope of these observations and their relevance for discrete two-stage and cascaded models of lexical access.
