Word predictability blurs the lines between production and comprehension: Evidence from the production effect in...

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Language processing relies on predicting upcoming input.
• The precise mechanisms for generating these predictions are not fully understood.
• One hypothesis suggests covert use of the production system during comprehension.

Purpose of the Study:

• To investigate whether reading predictable words involves covert speech production.
• To examine the memory consequences of this covert production.
• To test the hypothesis that covert production reduces the production effect for predictable words.

Main Methods:

• Participants read predictable and unpredictable words aloud or silently.
• A surprise recognition memory task was administered.
• Experiment 1 used old/new judgments; Experiment 2 used aloud/silent judgments.

Main Results:

• The production effect (better memory for aloud vs. silent reading) was smaller for predictable words than unpredictable words (Experiment 1).
• Participants had more difficulty distinguishing between aloud and silent reading for predictable words compared to unpredictable words (Experiment 2).

Conclusions:

• Findings support the hypothesis that reading predictable words involves covert production.
• Covert production during reading has measurable consequences for memory retention.
• Word predictability appears to blur the distinction between language production and comprehension systems.
