Processing of compound-word characters in reading Chinese: an eye-movement-contingent display change study.

Readers' eye movements were monitored as they read Chinese two-constituent compound words in sentence contexts. The first compound-word constituent was either an infrequent character with a highly predictable second constituent or a frequent character with an unpredictable second constituent. The parafoveal preview of the second constituent was manipulated, with four preview conditions: identical to the correct form; a semantically related character to the second constituent; a semantically unrelated character to the second constituent; and a pseudocharacter. An invisible boundary was set between the two constituents; when the eyes moved across the boundary, the previewed character was changed to its intended form. The main findings were that preview effects occurred for the second constituent of the compound word. Providing an incorrect preview of the second constituent affected fixations on the first constituent, but only when the second constituent was predictable from the first. The frequency of the initial character of the compound constrained the identity of the second character, and this in turn modulated the extent to which the semantic characteristics of the preview influenced processing of the second constituent and the compound word as a whole. The results are considered in relation to current accounts of Chinese compound-word recognition and the constraint hypothesis of Hyönä, Bertram, and Pollatsek ( 2004 ). We conclude that word identification in Chinese is flexible, and parafoveal processing of upcoming characters is influenced both by the characteristics of the fixated character and by its relationship with the characters in the parafovea.
