Word length does not modulate the transposed-word effect in Chinese reading: Testing the OB1-Reader.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Reading Science

Background:

• Grammaticality decision studies reveal flexible word order processing during reading.
• The OB1-Reader model attributes transposed-word effects to positional uncertainty, influenced by visual cues like word length.
• Absence of word-length effects in Chinese reading is linked to limited word length variability and lack of explicit word boundaries.

Purpose of the Study:

• Investigate if marking word boundaries in Chinese text elicits a word-length effect on transposed-word detection.
• Determine if explicit boundary cues improve transposed-word detection in Chinese.
• Assess the influence of low-level visual cues on positional processing in Chinese compared to alphabetic scripts.

Main Methods:

• Experiment 1: Marked Chinese word boundaries using interword spaces.
• Experiment 2: Used alternating text colors to delineate word boundaries.
• Analyzed transposed-word effects and the role of word length in both experiments.

Main Results:

• Both experiments demonstrated robust transposed-word effects in Chinese.
• Explicit boundary cues showed some improvement in transposed-word detection.
• No evidence was found that boundary cues elicited a word-length effect on transposed-word detection.

Conclusions:

• Boundary cues do not reliably reduce positional uncertainty in Chinese.
• Low-level visual cues like word length have limited influence on positional processing in Chinese.
• Findings suggest limited impact of visual cues on positional processing across both alphabetic scripts and Chinese.
