About

Dr Guest’s research involves creating computational models of cognition, specifically category learning in infancy. She is currently investigating the impact language has on developing cognition, on the formation of category boundaries, and on the ability to generalise from novel experiences. 

She uses various types of connectionist networks, including self-organising maps, to explore the potential roles words can play. Such models can be used to provide support for both mechanistic and functional accounts of how words can modulate category learning. This computational modelling work aims to explore whether words act as supervisory signals that facilitate the formation of categories, whether they act as features akin to sensory input, or whether words have both these two roles as a function of development.
