I'm trying to read here! How does irrelevant speech affect how you read?

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Reading integrates perceptual and linguistic processes, closely coupled with lexical properties.
• Irrelevant speech is a common source of interference during reading.
• The impact of irrelevant speech on reading eye movements and lexical processing remains unclear.

Purpose of the Study:

• To investigate how intelligible irrelevant speech affects the coupling between reading eye movements and lexical difficulty indicators.
• To determine if irrelevant speech disrupts early lexical processing or later, higher-order reading processes.

Main Methods:

• Fifty-nine English-speaking participants read passages under conditions of intelligible irrelevant speech and silence.
• Eye movements were recorded during reading.
• The study analyzed the influence of word frequency, predictability, morpho-syntax, and semantics on eye movements.

Main Results:

• Associations between lexical variables and initial word viewing times remained robust, unaffected by irrelevant speech.
• Disruption was observed in later eye movement measures, specifically total viewing time.
• Low-frequency and semantically unpredictable words led to increased re-reading under irrelevant speech.

Conclusions:

• Intelligible irrelevant speech selectively interferes with post-lexical, higher-order reading comprehension processes.
• Readers may employ compensatory strategies, such as increased re-reading, to overcome speech interference and integrate meaning.
• Lexical processing during the initial stages of reading appears resilient to irrelevant speech.
