−1.89, p = .07) temporal regions. For the frontal region, a significant association was observed (β = −0.77, SE = 0.26, t = −2.99, p = .004). However, Cook's distance and robust regression analyses identified three observations as outlying cases. After removal of the detected cases, no significant associations were observed (β = −0.34, SE = 0.19, t = −1.76, p = .09). In the following we report results based on unadjusted frequency bands.
