Automatic perceptual simulation of first language meanings during second language sentence processing in bilinguals

Area of Science:

• Cognitive Science
• Psycholinguistics
• Neuroscience

Background:

• Language comprehension involves embodied simulation, engaging sensory, motor, and emotional brain areas.
• A key criticism suggests findings may stem from conscious image generation, not automatic simulation.

Purpose of the Study:

• To investigate whether automatic language processing in bilinguals is modulated by embodied simulation.
• To test if embodied simulation is an automatic process independent of conscious strategies.

Main Methods:

• Dutch-English bilingual participants were presented with English sentences containing interlingual homophones.
• Sentences implied specific distance relations, followed by responses to pictures of objects.
• Reaction times were measured for matching and mismatching perceptual features.

Main Results:

• Participants were significantly slower to reject critical items when perceptual features matched the implied distance.
• This indicates automatic simulation of interlingual homophone meanings.

Conclusions:

• Bilinguals automatically simulate meanings of interlingual homophones in a detailed perceptual manner.
• Embodied simulation is an automatic component of meaning construction, not solely reliant on conscious strategies.
