Eye-Movement Evidence for Object-Based Attention in Chinese Reading

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Visual Perception

Background:

• Understanding attentional allocation during reading is crucial for models of visual processing.
• Previous research on object-based attention provides a framework for investigating selective attention in complex visual scenes.
• The nature of attentional focus on linguistic units, such as words, remains an active area of investigation.

Purpose of the Study:

• To determine if attention during reading is allocated to single words or multiple words simultaneously.
• To investigate the role of word frequency in lexical decision and reading tasks when words are spatially presented.
• To explore whether attentional processes in reading align with principles of object-based attention.

Main Methods:

• Lexical decision tasks were employed with spatially colocated Chinese words and nonwords.
• Eye-tracking was utilized to measure looking times and fixation positions during sentence reading.
• Participants performed tasks under conditions designed to isolate attentional effects on word processing.

Main Results:

• In lexical decision tasks, only the frequency of the attended word influenced response times and accuracy.
• During sentence reading, only target word frequencies affected looking times and fixation positions.
• These findings indicate that attentional resources are narrowly focused during word processing in reading.

Conclusions:

• Reading involves a serial attentional process, focusing on one word at a time.
• Words may be treated as distinct visual objects during attentional allocation in reading.
• The results have implications for eye-movement control models and the conceptualization of words as objects.
