Time course of orientation biases averaged across observers. (A) Distribution of key presses averaged across all observers and normalized by the maximum number of key presses for ±82 ms around the target. Note the clear emergence of the TI (positive peak) as well as the indirect TI (negative peak). Lower: Distribution of key presses for the TI and indirect TI summed across all observers plotted together over the 100 frames (B) and over 40 frames flanking the target (C). Shaded colored areas encompass the 95% confidence intervals centered on the means.
