Experimental design and behavioral results from spatial target detection task.

<p>A) In this excerpt from a sequence the target location is at the left side (-90°). The four conditions are shown at the top, with the Baseline, Post-1 and Post-2 examined in this report. B) Plot of reaction time for left and right targets across the three conditions. There was a progressive reduction in reaction time across conditions, and did not differ among left or right target locations. C) Illustration of the method to calculate the slope of ERP amplitudes across the four non-targets at each sample point (“FCz ERP”). Data showing a linear fit across the non-target ERP amplitudes at 300 ms latency are shown at the right (labeled “linear fit”). The slopes at each sample point from 0–1000 ms were calculated and plotted as a waveform of the slope values (uV/degree) as a function of time (bottom, labeled “slope”). The vertical line in 1C indicates the time point for the amplitudes that are plotted in the “linear fit” panel.
