Figure 2.

Behavioral performance on the 1-back task during fMRI. ( A ) Performance on the 1-back task during fMRI for children (gray) and adults (black) was highly accurate. There were no significant differences across age groups, or interactions between age and stimulus category across visual stimuli in mean accuracy. Results were similar when we considered responses to all visual stimuli, or just responses to faces. Error bars: group SEM. ( B ) Response times in the 1-back task during fMRI were significantly slower in children than in adults across all stimulus types. Error bars: group SEM. Asterisk: significant main effect of age group, P < 0.0001.
