Researchers have conducted a study to evaluate the sensitivity of language models to discourse particles like "just" and "only." The study found that both humans and language models show a similar preference for these particles in conversational contexts, with "just" eliciting a stronger response than "only." Language models consistently rated generated text as more likely when these particles were present, indicating a sensitivity that is further enhanced by instruction tuning. Mechanistic analysis revealed that the internal representations of "just" and "only" within language models are partially organized by sense, with an asymmetric transfer of understanding between the two particles.
