Attention explores space periodically at the theta frequency

The amplitude of the 4 Hz component for individual observers. An FFT was perform. For each observer separately for both the P1-P2 difference (A) and the Discriminant (B) for valid and invalid conditions. Whenever, empty black circles represent the amplitude of the 4 Hz component for individual observers. Black-filled circles represent the average across observers. Error bars reflect 95% confidence intervals. The difference between valid and invalid conditions was significant for both the P1-P2 difference (t(10) = 3.86, p = 0.001, Cohen’s d = 1.647) and the Discriminant (t(10) = 3.36, p = 0.004, Cohen’s d = 1.383).
