Language models retain abandoned sentence analyses, study finds

A new research paper explores how large language models process and retain information from sentences that require re-analysis, similar to how humans handle garden-path sentences. The study found that models, across various sizes, exhibit a 'residue' from abandoned analyses that influences subsequent text generation and an 'adaptation' that adjusts based on the sentence's disambiguation error. Activation patching was used to differentiate these two effects, revealing that the residue is carried by role information in noun phrase states computed under the abandoned analysis, while adaptation stems from states processing the disambiguation.
