From: Alpha-band sensory entrainment alters the duration of temporal windows in visual perception
Power spectrum of perceptual oscillations induced by the entrainment. (A) Raw data were sorted for each participant as a function of the delay between the entrainment offset and the appearance of the first target display, and then preprocessed (see Methods) to calculate (B) the Fast Fourier Transformation (FFT) from which we extracted the power spectra of perceptual oscillation. In both (A) and (B) data were averaged across participants, with shaded area representing the SEM. (C) Plot showing the mean FFT peak across participants as a function of the entrainment frequency (IAF − 2 Hz vs. IAF + 2 Hz) and task condition (segregation vs. integration) (*p < 0.05, one tail t-test).
