LVLMs and Humans Ground Differently in Referential Communication

Large vision-language models cannot interactively generate and resolve referring expressions to build common ground with humans or each other.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We show that LVLMs cannot interactively generate and resolve referring expressions in a way that enables smooth communication, a crucial skill that underlies human language use.

C2weakest assumption

The assumption that performance differences in this specific non-lexicalized object matching task directly reflect broader deficits in LVLMs' ability to model common ground in general communication.

C3one line summary

LVLMs and humans build common ground differently in referential tasks, with LVLMs failing to enable smooth interactive communication in a new corpus of 356 dialogues.
