文摘

The present study investigated the interaction of semantic and orthographic processing during compound sinogram recognition, using event related potentials (ERPs) and a picture-word matching task. The behavioral results showed that participants generally needed more time to make a response and were more prone to make mistakes, when the paired mismatch sinogram was orthographically similar or semantically related to the picture’s matching name. The N400 results indicated the main effect of semantics and the significant interaction of semantics by orthography. Moreover, only under the semantically related condition (S+), the mean amplitude of N400 was more negative going in orthographically similar condition (O+) than in orthographically dissimilar one (O-), while there was no significant difference under the semantically unrelated condition (S-). Consequently, the sub-lexical orthographic information plays an important role in discriminating the sinograms sharing related semantics.
