The neural substrates of abstract/concrete word processing Gabriella Vigliocco, UCL Stavroula-Thaleia Kousta, UCL Joseph T. Devlin, UCL Stefano Cappa, Università Vita-Salute San Raffaele
Background • Concrete > Abstract(Bleasdale, 1987; Paivio, 1986; Schwanenflugel et al., 1989) • Concrete = Imageable Abstract = Non-imageable • Partially distinct brain systems underlie the processing of concrete and abstract concepts (Binder et al., 2005; Sabsevitz et al., 2005; but see Grossman et al., 2002; Kiehl et al., 1999; Noppeney & Price, 2004) • Abstract > Concrete(Kousta et al., in prep.) Question: What are the neural correlates of abstract/concrete word processing when confounding variables have been controlled?
