purpose examine neural response spoken printed language children speech sound errors sse method functional magnetic resonance imaging used compare processing auditorily visually presented words pseudowords 17 children sse ages 86yearsmonths 1010 17 matched controls results processing spoken words pseudowords sse group showed less activation typically speaking controls left middle temporal gyrus also showed greater activation controls several cortical subcortical regions eg left superior temporal gyrus globus pallidus insula fusiform bilateral parietal regions response printed words pseudowords children sse greater activation controls regions including bilateral fusiform anterior cingulate differences found speech print processing may associated children sse failing show common patterns taskinduced deactivation andor attentional resource allocation conclusion compared controls children sse appear rely several dorsal speech perception regions less ventral speech perception regions processing print numerous regions observed activated sse group controls
