Figure 3. Mapping cognitive processes to brain activation.
Left: Dual route model of reading that dissociates the processing of lexical and sublexical orthographic inputs. Middle: A simpler model of reading that explains the same symptoms without having separate pathways for lexical and sublexical processing (Seidenberg and McClelland,1989; Plaut et al., 1996). Black text is used for inputs, processing type and outputs. White text, in grey boxes, indicates the type of stimulus that would be impaired when a specific pathway was damaged. Right: Brain activations for reading segregated into visual/orthographic (red), semantic (yellow) and speech production (green) processing. The brain activations shown were identified by re-analysis of data from the experiment described in Seghier and Price (2012).
