Metaphor processing is automatic, but working memory (WM) capacity influences its speed. Higher WM reduces the metaphor interference effect (MIE), suggesting executive control over early metaphor interpretation.
Area of Science:
- Cognitive Psychology
- Psycholinguistics
Background:
- Metaphor comprehension is a fundamental aspect of human language.
- The metaphor interference effect (MIE) indicates that metaphor processing is automatic.
- The role of executive functions, such as working memory (WM), in metaphor processing remains under investigation.
Purpose of the Study:
- To investigate the relationship between working memory (WM) capacity and the metaphor interference effect (MIE).
- To explore how executive mechanisms influence the automatic processing of metaphors.
Main Methods:
- Participants judged the literal falsity of metaphors and scrambled sentences.
- The magnitude of the metaphor interference effect (MIE) was measured.
- Individual differences in working memory (WM) capacity were assessed.
Main Results:
- Participants exhibited a significant metaphor interference effect (MIE), taking longer to reject literal falsity for metaphors than for scrambled sentences.
- Higher working memory (WM) capacity was associated with a smaller MIE.
- This suggests that executive control mechanisms can modulate early metaphor processing.
Conclusions:
- Metaphor comprehension, while automatic, is subject to modulation by executive functions, particularly working memory (WM).
- Working memory (WM) influences the construction-integration process and the speed of literal vs. figurative meaning identification.
- These findings contribute to understanding the interplay between automatic and controlled processes in language comprehension, aligning with predictive models of cognition.
