- Humans possess strong inductive and deductive reasoning skills and sophisticated communication through language, but the relationship between logical reasoning and language is debated.
- fMRI studies on healthy adults and behavioral evaluations of severe aphasia patients show that the language brain network is not engaged during logical reasoning.
- Inductive reasoning activates the domain-general multiple demand network, while deductive reasoning involves distinct brain regions separate from both language and multiple demand networks.
- Linguistic representations are not utilized or required for logical reasoning, indicating that logical inference operates independently from language processing in mature brains.
