Performance data during response inhibition tasks.
Table 3.
The oxy-Hb concentration in the prefrontal cortex during response inhibition tasks.
Figure 2.
The performance of the three groups during No-go task.
A: the reaction time of the No-go task; B: the oxy-Hb levels in the prefrontal cortex. Compared to TD, HFA and ADHD individuals required a longer reaction time during the No-go task. Both the reaction time and oxy-Hb level in the right prefrontal cortex are highest in HFA and lowest in TD. **: P<0.01; *: P<0.05.
Figure 3.
The performance of the three groups during incongruent task.
A: The reaction time of incongruent task; B: the oxy-Hb levels in the prefrontal cortex. HFA and ADHD individuals had lower oxy-Hb levels in the left and HFA and ADHD individuals had lower oxy-Hb levels in the left and inferior prefrontal areas, and longer reaction times, than typically developing children.
