Evidence for role-neutral initial processing of metaphors

Area of Science:

• Cognitive Psychology
• Linguistics
• Psycholinguistics

Background:

• Two prominent models of metaphor processing exist: structure-mapping and attributive categorization.
• The structure-mapping model suggests role-neutral alignment followed by inference projection.
• The attributive categorization model posits role-specific processing throughout comprehension.

Purpose of the Study:

• To empirically test and differentiate between the structure-mapping and attributive categorization models of metaphor processing.
• To investigate the temporal dynamics and role-sensitivity of early metaphor comprehension stages.

Main Methods:

• Utilized a reaction time (RT) based interference paradigm, building on Glucksberg et al.'s (1982) findings.
• Conducted three experiments manipulating metaphor structure and term order.
• Measured interference effects and full comprehension RTs to distinguish early vs. late processing stages.

Main Results:

• Experiment 1 and 2 showed no significant difference in interference effects for normal vs. reversed metaphors, indicating role-neutral initial processing.
• Experiment 3 confirmed that full metaphor comprehension is role-sensitive and significantly slower than early interference effects.
• Interference effects were observed even for highly conventional metaphors, supporting early, role-neutral processing.

Conclusions:

• The findings provide strong support for the structure-mapping model of metaphor processing.
• Early stages of metaphor comprehension are characterized by role-neutral alignment.
• Later stages of comprehension involve role-specific interpretation, aligning with the structure-mapping model's predictions.
