McGovern neuroscientists have discovered that you don't need language to think logically. People with severe language impairments solve complex reasoning puzzles perfectly and brain scans show language areas remain silent during logical reasoning.

Does logical reasoning require language? According to new research from @ev_fedorenko, @HopeKean, and collaborating neuroscientists, study participants were able to solve various complex logic games and puzzles without language, showing that: no, language is not necessary. ⬇️

Humans largely learn language through speech. In contrast, most LLMs learn from pre-tokenized text. In our #Interspeech2025 paper, we introduce AuriStream: a simple, causal model that learns phoneme, word & semantic information from speech.

Thus, linguistic representations do not undergird abstract logical reasoning, 🚫 adding to the body of evidence that we don’t use language to think. 🧩 7/8

🌟To conclude: neither linguistic nor domain-general abstract representations (in the MD system) underlie intuitive physical reasoning! The physical-reasoning system therefore appears to be another specialized reasoning system, akin to the Theory of Mind Sys (@rebecca_saxe)! 9/10
