Figure 6. Decrease in instantaneous amplitude (IA) correlates with behavioral impairment.

Figure 6

The decrease in IA of the RSVP SSVEP due to distraction correlated positively across subjects with participants’ impairment in target detection. For this analysis, the average IA was extracted from a posterior ROI (illustrated) from epochs time-locked to the onset of Nontargets with and without Distractors (latency used 0–600 ms). These values were then entered into a correlational analysis with the same accuracy measures used for Figure 4D (i.e. degree of impairment in the critical 0–116 ms bin window for Distractor occurrence). The results indicate that the larger the decrease seen in the IA with distraction, the greater the behavioral impairment also observed.
