Control for potential onset-offset (nonperiodic) effects. The analysis from Figures 3 to 6 was replicated with estimated
attentional functions truncated for the first 83 ms and the last 83 ms (leaving only the central 333 ms portion of the
original 500-ms-long functions). (A) For the easy search task, no frequency reached significance in the amplitude
spectrum of the grand-average attentional function (middle; note that the frequency resolution of this analysis is 3 Hz
instead of 2 Hz because of the shortened duration of the sampling function). In the average amplitude spectrum of
individual attentional functions (right), significance (p value <10−3) was reached for three frequencies: 3 Hz, 6 Hz, and 9
Hz. of
