We investigated whether orthographic information influences speech production. We used a non-color-word version of the Stroop task in which participants had to ignore the presented words but name their ink color instead. In two experiments, we manipulated the phonological and orthographic relationships between the words and their ink color and the tasks' context by preactivating or not orthographic information. The relation between the first letter of the prime word and the first phoneme of the color name was phonological or orthographic and phonological or unrelated. In Experiment 1, only phonological information carried out by the prime word affected spoken naming; orthographic information did not help. In Experiment 2, speech production was influenced by orthographic information only after an initial writing task. This confirms that orthographic information can support speaking and that speech is sensitive to properties of the task's context, suggesting that orthographic information is coactivated online with phonological information.
我们研究了正字法信息是否会影响言语产生。我们使用了Stroop任务的非颜色词版本,即参与者必须忽略呈现的单词,而是说出其墨水颜色。在两个实验中,我们通过预先激活或不激活正字法信息,来操纵单词与其墨水颜色之间的语音和正字法关系以及任务背景。启动词的首字母与颜色名称的首个音素之间的关系是语音的、正字法和语音的或不相关的。在实验1中,启动词所携带的语音信息仅影响口语命名;正字法信息并无帮助。在实验2中,只有在完成初始书写任务后,言语产生才会受到正字法信息的影响。这证实了正字法信息可以支持言语表达,并且言语对任务背景的属性敏感,这表明正字法信息在在线过程中与语音信息共同被激活。
