Figure 4.

(a) In all participants (Bar 1) in the Child Group, cortical lateralization (CL) scores (100 × (dipole moment in right auditory cortex − dipole moment in left auditory cortex)/sum of right and left dipole moments) evoked by left ear stimulation are more positive (increased activity in the right auditory cortex) than by right ear stimulation. This is true for both click‐trains and tone‐bursts. This pattern is more variable in the Adolescent Groups. (b) Mean ± 1 SE CL values are shown for all time windows in the Child Group and both Adolescent Groups; solid lines are significantly different from 0 whereas dashed lines are not significant. In the Child Group, the CL score was significantly more positive (increased activity in right hemisphere) when evoked by the left than right ear stimulation during the iP1 time window (**p < .01). In adolescents listening to tone‐bursts, CL scores were significantly more positive when evoked by stimulation to the left than right ear (**p < .01), but this difference was not significant in the adolescents listening to tone‐bursts
