Inter-character Orthographic Similarity Effects on the Recognition of Chinese Coordinative Compound Words.

Chinese coordinative compound words are common and unique in inter-character semantic and orthographic relationships. This study explored the inter-character orthographic similarity effects on the recognition of transparent two-morpheme coordinative compound words. Seventy-two native Chinese readers participated in a lexical decision task. The findings demonstrated robust inhibitory inter-character orthographic similarity effects, intra-word character reversal effects, and inter-character semantic similarity effects. These results were compared to those of previous studies on coordinative compound word recognition and on the orthographic similarity phenomenon at both character and word levels. The findings were explained with the multi-level representational model of morphological processing of Chinese compound words (Zhou and Marslen-Wilson in Psychologia 43:47-66, 2000). The model was further extended by adding the activation of morpho-orthographic relationships and the mapping of morphemic orthographic information onto the semantic information of both morphemes and whole words.
