The transposed word effect is consistent with serial word recognition and varies with reading speed

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Reading Science

Background:

• The debate on parallel versus serial word recognition in reading is ongoing.
• The transposed word effect (TWE) is a phenomenon where readers miss grammatical errors caused by transposed words, potentially indicating parallel processing.
• Previous research has explored TWE, but its consistency with serial processing remains debated.

Purpose of the Study:

• To investigate whether the transposed word effect (TWE) is also consistent with serial word recognition.
• To examine the influence of presentation mode (simultaneous vs. sequential) on TWE.
• To explore the relationship between individual reading speed, gaze patterns, and TWE.

Main Methods:

• Assessed natural English reading rates of 37 participants.
• Conducted a grammatical decision task using simultaneous and sequential word presentation.
• Analyzed error rates and response times in relation to sentence grammaticality and presentation mode.

Main Results:

• The magnitude of the transposed word effect was comparable in both simultaneous and sequential presentation modes.
• Faster readers were more prone to missing transposed words in the sequential presentation.
• Response times and error rates indicated a robust TWE regardless of presentation speed.

Conclusions:

• The transposed word effect is compatible with serial word recognition, challenging purely parallel processing models.
• Skilled readers may utilize prior knowledge and context to infer meaning, even with sequential word input.
• Findings support a 'noisy channel' model of reading comprehension, emphasizing predictive processing.
