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

Area of Science:

• Cognitive Psychology
• Linguistics
• Visual Perception

Background:

• The visual complexity of written characters, such as the number of strokes in Chinese characters, is a potential factor influencing reading processes.
• Previous research has not fully elucidated whether these visual complexity effects are mediated by linguistic processing or more fundamental visual mechanisms.

Purpose of the Study:

• To investigate the influence of Chinese character complexity on eye-movement behavior during reading tasks.
• To determine if visual complexity effects persist even in the absence of lexical knowledge.

Main Methods:

• Three experiments involving eye-tracking were conducted.
• Participants included English speakers with no Chinese knowledge and native Chinese speakers.
• Tasks involved searching for target characters and reading a narrative text.

Main Results:

• Fixation durations and skipping rates were affected by character visual complexity in all experiments.
• These effects were observed even when participants lacked knowledge of Chinese word meanings.
• Complexity influenced eye movements during both character search and general reading.

Conclusions:

• Character complexity effects on eye movements appear to be driven by visual processing demands rather than solely by lexical processing.
• These findings suggest that basic visual processing plays a significant role in how readers interact with complex scripts.
• The results have implications for understanding the fundamental mechanisms of normal reading across different writing systems.
