Theoretical and computational models

In the years, we have developed theoretical and computational proposals of how humans represent the meaning of words in their mind/brain.

We have developed theoretical and explicit computational models of the representation and learning of word meaning across domains of knowledge (how we represent objects, actions and abstractions). These models are motivated by insights from cognitive psychology, neuroscience and linguistics (Vigliocco, et al., 2004; Andrews, et al, 2009; Andrews & Vigliocco, 2010; Vigliocco et al., 2009) and use information extracted from sensory-motor experience (embodied information) crucially combined with information extracted from language to represent meaning. In recent work, we have combined distributional semantics and spreading of activation (Rotaru, Frank & Vigliocco, in press).

In other modelling work, we have assessed the fit of information theoretical measures such as听surprisal to reading (behavioural and EEG data, Fernandez-Monsalve et al., 2012; Frank et al., 2013; 2015). We are now extending this work to multimodal communication (Zheng, et al., in prep).

Having explicit models of how humans represent meaning has allowed us to tackle a number of other long-standing issues such as: (i)听linguistic relativity (our work has shown surprisingly limited domains in which effects of linguistic relativity are observed, Vigliocco et al., 2005; Iwasaki et al., 2010).听 (ii) the representation of nouns and verbs in the brain (our work provides behavioural and imaging evidence in favour of semantic, rather than syntactic, neural organisation, e.g., Iwasaki et al., 2008; Siri et al., 2008; Vigliocco et al., 2005; Vigliocco et al., 2011). (iii) representational differences between concrete and abstract words (Rotaru et al., in prep.)
