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 = ImageableAbstract = 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?
Lexical Decision 4 Conditions (Abstract, Concrete, Pseudowords, Letter Strings; 240 trials/60 per condition) + Baseline Mixed (block and event-related design): … t + sum ? + qlv + edy ? + rod *** ~60s 15s
