Multidimensional Semantics for Concrete and Abstract Concepts

Penny M. Pexman

Multiple representation theories posit that concepts are represented via a combination of properties derived from sensorimotor, affective, linguistic, and other experiences. One advantage of this approach is that it helps address the challenge of abstract meanings, like wisdom and friendship, which are central to our mental and social lives and yet cannot be directly experienced through the senses. I will describe a series of studies in which my colleagues and I have tested predictions of multiple representation theories for acquisition and processing of concrete and abstract word meanings, exploring the roles of sensorimotor, interoceptive, and social experience. The development of large-scale word norms and behavioural megastudies has enabled consideration of multiple lexical and semantic dimensions and exploration of the possibility that these dimensions have simultaneous and interacting effects on behaviour. Using these “big data” I will consider how these multiple factors might be mapped in semantic space.

Penny’s research expertise is in cognitive development, psycholinguistics, and cognitive neuroscience. In broad terms, she is interested in how we derive meaning from language, and how those processes are changed by experience. She has published more than 150 journal articles on those topics. For over 2 decades her work has been continuously funded by two of Canada’s federal funding organizations (SSHRC and NSERC), including NSERC’s prestigious Discovery Accelerator Supplement. She is an elected fellow of the Canadian Psychological Association and the Association for Psychological Science and has been honoured with 9 awards for mentorship and teaching excellence.
