The results showed that participants with autism were slower to press on the key when the target X was presented than typically developing peers. However, the groups did not differ in accuracy of responding.

That is, both groups were equally accurate in responding to the X target, but the group with autism showed a slower patter of responses. The group with autism also showed a different pattern of brain activation when confronted with the novel distracters. Their differences were observed in both hemispheres, but were stronger in the right frontal regions. The pattern of responses observed (longer latencies and higher amplitudes) suggest greater effort when processing novel stimuli. This finding is intriguing because the brain response patterns to the other stimuli (target X and the common distracter O) were identical between the groups. These results suggest that the group with autism had difficulty processing and disengaging from novel distracting stimuli.

In neurofeedback, the person receives real-time feedback on their brain functioning and is taught how to progressively modify their responses. However, the debate regarding the effectiveness of neurofeedback is ongoing as the research is limited and highly contradictory.
