Summary
Prior domain knowledge significantly impacts understanding novel metaphors. Expertise in a subject, like engineering, reduces the cognitive effort needed to process domain-specific creative language.
Area of Science:
- Cognitive Neuroscience
- Psycholinguistics
- Neuroscience
Background:
- Novel metaphor comprehension is cognitively demanding, requiring integration of distantly related concepts.
- Electrophysiological studies indicate a cognitive cost associated with processing novel linguistic expressions.
- The role of prior domain-specific knowledge in mitigating this cost remains underexplored.
Purpose of the Study:
- To investigate whether prior domain knowledge influences the cognitive cost of novel metaphor comprehension.
- To examine the neural correlates of processing literal, metaphorical, and anomalous sentences in relation to domain expertise.
- To determine if domain-specific knowledge attenuates the processing of novel metaphors within that domain.
Main Methods:
- Electroencephalography (EEG) recording during sentence comprehension tasks.
- Participants included engineering and non-engineering students reading literal, novel metaphorical, and anomalous sentences.
- Post-reading judgments on sentence novelty and sensicality were collected.
Main Results:
- A graded N400 modulation was observed across sentence types: anomalous > metaphorical > literal.
- Engineers showed an attenuated N400 response to novel metaphorical sentences compared to non-engineers.
- Engineers exhibited reduced N400 amplitudes for engineering-specific novel metaphors versus non-engineers.
Conclusions:
- Prior domain knowledge directly impacts the cognitive processing of creative language, specifically novel metaphors.
- Domain expertise can reduce the neural effort required for comprehending domain-relevant metaphorical language.
- These findings provide novel evidence for the influence of knowledge on metaphor processing and creative language understanding.

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...
