In summary, our ERSP data suggest that a smaller frequency window (5-6.5) Hz may better characterize “theta” for greater response to no win vs. win feedback in our child and adolescent sample (ERSP Condition Effect 1, Figure 4A), with the full range of theta (4-8 Hz) being engaged differentially only later in stimulus processing (Condition Effect 2, 500-550 ms, Figure 3 (Age Group) and Figure 4B). Age effects suggest that the 13-14-year-old group produces greater theta activity than the older group for early feedback stimulus processing at 50-150 ms and 4-5 Hz (Figure 4C) and greater theta activity than the younger group at 300-400 ms and 4-6 Hz (Figure 4D).
