Exploring the Character Transposition Effect and Locus in Chinese Word Recognition: Evidence from Left-Right Visual...

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• The letter transposition effect is well-documented in alphabetic languages but understudied in logographic systems like Chinese.
• Existing research on Chinese word recognition predominantly features adult participants.

Purpose of the Study:

• To investigate the character transposition effect in second-grade children recognizing two-character Chinese words.
• To explore potential hemispheric differences in processing this effect using a visual field presentation paradigm.

Main Methods:

• Two experiments employed a lexical decision task with second-grade students.
• Experiment 1 used normal words, transposed pseudo-words, and substituted pseudo-words to confirm the effect.
• Experiment 2 utilized a lateralized presentation (left/right visual field) to assess hemispheric involvement (left/right hemisphere).

Main Results:

• A significant character transposition effect was observed in second-grade children.
• No significant differences were found in the magnitude of the transposition effect between the right visual field (left hemisphere) and left visual field (right hemisphere).

Conclusions:

• This study provides novel developmental evidence for the character transposition effect in Chinese word reading.
• Findings suggest consistent positional encoding mechanisms across hemispheres in young Chinese readers.
• Further research should examine the developmental trajectory across broader age groups and contexts.
