Predictability eliminates neighborhood effects during Chinese sentence reading

Area of Science:

• Psycholinguistics
• Cognitive Science
• Computational Linguistics

Background:

• Orthographic neighborhood size and neighbor frequency influence Chinese word recognition.
• Larger neighborhoods facilitate recognition, while high-frequency neighbors inhibit it.

Purpose of the Study:

• To investigate how word predictability in context modulates neighborhood effects in Chinese word recognition.
• To examine the interaction between contextual predictability and orthographic neighborhood characteristics.

Main Methods:

• Two eye-movement experiments were conducted using Chinese sentences.
• Target words were manipulated for neighborhood size (Experiment 1) and neighbor frequency (Experiment 2).
• Contextual predictability of target words was systematically varied.

Main Results:

• Previously observed effects of neighborhood size and neighbor frequency were replicated in unpredictable contexts.
• These neighborhood effects disappeared when the target word was highly predictable.
• Contextual preactivation appears to reduce the competition from orthographic neighbors.

Conclusions:

• Contextual predictability plays a crucial role in modulating orthographic neighborhood effects.
• When a word is predictable, its neighbors are less likely to interfere with its recognition.
• These findings suggest a dynamic interaction between lexical access and contextual integration in reading.
