Arabella Sinclair, Assistant Professor at UCL (London) and at the University of Aberdeen will present her work who will present her work on large language models (LLMs), language processing, and cognition.
Abstract
Both humans and Large Language Models (LMs) generate predictions about upcoming words and structures based on recent context. In dialogue, speakers continuously choose how to realise their communicative intentions, with these choices shaped by multiple, sometimes competing pressures, including production costs borne by the speaker and comprehension costs incurred by the listener. Production costs reflect the effort involved in planning and generating an utterance, while comprehension costs reflect how easily an utterance can be processed and interpreted. These costs are influenced by a range of factors, including priming, utterance length, informational content, and contextual predictability.
In this talk, I explore how LMs can serve both as tools for studying human interaction and as components of broader cognitive models of language processing. First, I present evidence for parallels between humans and LMs in primed comprehension facilitation, showing how prior exposure to linguistic structures influences subsequent processing. Second, I discuss ongoing work investigating analogous effects in a controlled production setting. Finally, I introduce a new procedure for constructing contextual alternative sets that enables probabilistic pragmatic models of language production to be instantiated and evaluated at scale in open-ended communicative settings. This framework also provides a principled basis for comparing competing notions of communicative cost.
Taken together, these findings shed light on the mechanisms underlying LMs’ in-context learning behaviour while also assessing their potential as models of human linguistic processing and communicative decision-making.
