In two experiments, we investigated the processing of extrafoveal objects in a double-object naming task. On most trials, participants named two objects; but on some trials, the objects were replaced shortly after trial onset by a written word probe, which participants had to name instead of the objects. In Experiment 1, the word was presented in the same location as the left object either 150 or 350 msec after trial onset and was either phonologically related or unrelated to that object name. Phonological facilitation was observed at the later but not at the earlier SOA. In Experiment 2, the word was either phonologically related or unrelated to the right object and was presented 150 msec after the speaker had begun to inspect that object. In contrast with Experiment 1, phonological facilitation was found at this early SOA, demonstrating that the speakers had begun to process the right object prior to fixation.
在两项实验中，我们在双物体命名任务中研究了中央凹外物体的加工过程。在大多数试验中，参与者对两个物体进行命名；但在一些试验中，试验开始后不久物体就被一个书面单词探针所取代，参与者必须对该单词而非物体进行命名。在实验1中，单词在试验开始后150毫秒或350毫秒出现在与左侧物体相同的位置，并且与该物体名称在语音上相关或不相关。在较晚而非较早的刺激呈现间隔（SOA）时观察到语音促进作用。在实验2中，单词与右侧物体在语音上相关或不相关，并在说话者开始检查该物体后150毫秒呈现。与实验1相反，在这个早期的SOA时发现了语音促进作用，这表明说话者在注视之前就已经开始加工右侧物体。
