Anna Ivanova) | Assistant Professor, School of Psychology | Georgia Tech College of Sciences "Dissociating Language and Thought in Humans and in Machines" “What is the relationship between language and thought? This question has long intrigued researchers across scientific fields. In this talk, I will propose a framework for clarifying the language-thought relationship. I will introduce a distinction between formal competence—knowledge of linguistic rules and patterns—and functional competence—understanding and using language in the world. This distinction is grounded in human neuroscience, where a wealth of evidence indicates that formal competence relies on a set of specialized brain regions (“the language network”), whereas functional competence requires the use of multiple non-language-specific neural systems. I will then present a series of case studies illustrating how the formal/functional competence distinction can help (a) delineate the functional architecture of the human brain, providing a framework for studying complex cognitive behaviors, such as computer coding and legal reasoning; (b) understand the capabilities and limitations of today’s large language models, particularly in the realm of general world knowledge.”
