Building on prior research demonstrating the transposed-character effect in word identification during sentence reading (using the boundary paradigm), which has been attributed to cognitive flexibility in character order processing, the present investigation extends understanding through systematic manipulation of semantic preview stimuli’s transition formats. The findings reveal two key insights: First, both semantic previews and their transposed stimuli produced equivalent preview benefits for subsequent target word identification. Second, compared to unrelated previews, transposed semantic previews conferred a distinct processing advantage. These results collectively suggest that cognitive flexibility in character order processing co-occurs with parafoveal semantic preview processing.
