For the non-blinkers, mean target durations were 67, 68, 67, and 68 ms for the standard stimuli, rotated targets, rotated distractors, and rotated stimuli condition, respectively.
For the blinkers, mean target durations were 74, 71, 80, and 75 ms for the standard stimuli, rotated targets, rotated distractors, and rotated stimuli condition, respectively.
For the non-blinkers, mean target duration was 137.8 ms in the rotated targets condition and 168.6 ms in the rotated distractors condition.
For the blinkers, mean target duration was 163.6 ms in the rotated targets condition and 185.6 ms in the rotated distractors condition.
Mean target duration was significantly lower for the candidate non-blinkers (72.5 ms) than for the candidate blinkers (80.0 ms), t(27) = 2.17, SE = 3.47, p = .04.04
In the standard AB condition, mean target duration was 67 ms for non-blinkers and 74 ms for blinkers, which, however, was not significantly different (p = .08).08
In the standard stimuli condition, non-blinkers had a significantly shorter mean target duration (61.9 ms) than blinkers (75.9 ms), t(17) = 2.24, SD = 6.27, p = .04.04
In addition, a significant effect of condition was found, F 1, 17) = 39.45, MSE = 167.22, p<.001, η2p = .70, such that the mean target duration in the rotated target condition was shorter than in the rotated distractors condition.
In the letters only conditions, mean target duration tended to be lower for non-blinkers (165 ms in the rotated targets condition and 180 ms in the rotated distractors condition) than for blinkers (171 ms in the rotated targets condition and 186 ms in the rotated distractors condition).
A separate mixed ANOVA with group (non-blinkers or blinkers) as between-subjects factor and condition (rotated targets or rotated distractors) as within-subjects factor revealed a significant effect of group, F 1, 17) = 10.06, MSE = 432.69, p = .006, η2p = .37, such that the mean target duration was shorter for the non-blinkers than for the blinkers.
The LHD group had a mean target duration of 327 ms (range 230-430 ms), and the control group had a mean target duration of 251 ms (range 180-330 ms).
