Contextual constraint and lexical competition: Revisiting biased misperception during reading

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Computational Neuroscience

Background:

• Readers rapidly identify words, often choosing between visually similar options.
• Misperceiving low-frequency words as frequent, similar alternatives is common, especially with contextual support.
• Previous research struggled to distinguish backward regression from forward text progression issues.

Purpose of the Study:

• To investigate the impact of postlexical competition on reading behavior.
• To differentiate between backward regression and forward text progression delays.
• To explore the mechanisms underlying word misperception and competition inhibition.

Main Methods:

• Three eye-tracking reading experiments were conducted.
• Materials from prior studies were adapted to include a postcritical spillover region.
• Ex-Gaussian analysis was used to examine first-pass reading time distributions.

Main Results:

• Evidence suggests postlexical competition-inhibition between orthographically similar words delays forward eye movement.
• The inhibition of a word competitor appears to slow down reading progression.
• The findings support the idea that similar word forms compete during lexical access.

Conclusions:

• Postlexical competition and inhibition mechanisms can influence reading speed and accuracy.
• The study provides insights into how the brain resolves competition between similar lexical items.
• The findings suggest that misperception and competition-inhibition may stem from shared underlying processes.
