Degrees of freedom and critical values: F(2, 20) = 3.49, F(2, 10) = 4.10, F(1, 5) = 6.61.

For drift rates:

Experiment 1: presentation duration (10, 20, or 40 ms), F(2, 20) = 135.82*, response type (eye movement, touch screen, or key press) F(2, 20) = 0.16, interaction F(4, 40) = 4.92*.

Experiment 2: presentation duration (10, 20, or 40 ms), F(2, 10) = 48.73*, response type (eye movement, or touch screen) F(1, 5) = 6.47, display (fixed, targets presented 0 ms before the stimulus, targets presented 500 ms before the stimulus) F(2, 10) = 21.12*.(One interaction is significant, response modality × presentation duration, F(2, 10) = 14.71).
