The Character Position Encoding of Parafoveal Semantic Previews Is Flexible in Chinese Reading

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• The Chinese character transposition effect suggests flexible positional encoding or morpheme-to-word activation in parafoveal processing.
• Previous studies show transposed characters within words offer greater parafoveal preview benefits than unrelated characters.

Purpose of the Study:

• To clarify the underlying mechanism of the Chinese character transposition effect.
• To investigate whether semantic information is extracted from parafoveal processing despite character order disruption.

Main Methods:

• Utilized an eye tracker to record participants' eye movements during reading.
• Manipulated four parafoveal preview conditions: identical, semantic, transposed semantic, and control (unrelated).
• Conducted two experiments using reversible and non-reversible word pairs as previews.

Main Results:

• Comparable processing was observed for both semantic and transposed semantic preview conditions.
• Transposed semantic previews provided a significant processing advantage over unrelated previews.
• Demonstrated that parafoveal processing is robust to character order disruptions in Chinese words.

Conclusions:

• Chinese readers extract semantic information efficiently from the parafoveal region, even with disrupted character order.
• Findings support the hypothesis of flexible character position encoding in parafoveal processing for Chinese.
• The study provides evidence for the adaptive nature of visual word recognition in Chinese.
