Location and timing of activation for visual word perception in children. The spatial distribution (left column) and mean time course of activation (right column) of the occipital visual feature sources (a), left occipitotemporal letter-string sources (b), and left and right temporal letter-string sources (c, d) are shown. Black and white circles represent sources of female and male subjects, respectively. The responses to the noisiest words, noiseless words, and symbol strings are plotted with different line types. The mean timing of the corresponding activations in adults (Helenius et al., 1999; Tarkiainen et al., 1999) is marked with a dashed line.
