Character-complexity effects in Chinese reading and visual search: A comparison and theoretical implications

Abstract

Three eye-movement experiments were conducted to examine how the complexity of characters in Chinese words (i.e., number of strokes per character) influences their processing and eye-movement behavior. In Experiment 1, English speakers with no significant knowledge of Chinese searched for specific low-, medium-, and high-complexity target characters in a multi-page narrative containing characters of varying complexity (3-16 strokes). Fixation durations and skipping rates were influenced by the visual complexity of both the target characters and the characters being searched, with the latter findings replicating previous reports (e.g., Liversedge et al., 2014) but in participants with no knowledge of Chinese. In Experiment 2, native Chinese speakers performed the same character-search task and a similar pattern of results was observed. Finally, in Experiment 3, a second sample of native Chinese speakers read the same text used in Experiments 1 and 2, with text characters again exhibiting complexity effects. These results collectively suggest that character-complexity effects on eye movements may not be due to lexical processing per se but may instead reflect whatever visual processing is required to know whether or not a character corresponds to an episodically-represented target (Baddeley, 2002). The theoretical implications of this for our understanding of normal reading are discussed.
