Similarly, for error rates a highly significant main effect of trial type has been revealed across the total sample (F (3,72) = 36.126, η 2 = .60, p<.001) and extreme groups (F (3,42) = 52.424, η 2 = .79, p<.001) indicating that detection of the task-relevant luminance change was highly impaired on perceptual conflict (LOB) trials.
