Eye movements have been shown to reflect word recognition and language processes during reading and auditory language comprehension.Moreover,recent research on spoken word planning has shown that eye movements similarly reflect speakers speech planning processes,and there is a close and systematic link between phonological activation and gaze shifting in spoken picture naming.So far,little work has been done to explore the relation between eye movements and written production.In the present study,we investigated whether eye movements reflect written planning processes in written picture naming.We adopted the picture-word interference paradigm with written responses,in which native speakers of Mandarin Chinese wrote the names of pictures in graphic tablet while attempting to ignore written distractor words.On a given trial,picture and distractor word were either both phonologically and orthographically related,only phonologically related,only orthographically related,or completely unrelated.Written response latencies showed that phonologically and orthographically related and only orthographically related distractors reliably facilitated written picture naming.More interestingly,similar patterns were shown in gaze duration.Phonologically and orthographically related and only orthographically related distractors reliably reduced the viewing time on pictures.Based on these findings,we conclude that eye movements indeed reflect cognitive planning processes in written picture naming,and the writers viewing time on pictures is contingent upon the encoding of the orthographic information of picture names.
