marginally significantp = .07
The analysis showed a marginally significant main effect of the response hand [ F (1, 36) = 3.59, p = .07, η 2 p = 0.091; left hand: M = -0.87 mm, SD = 1.71 mm; right hand: M = -0.63 mm, SD = 1.59 mm], and no significant main effect of the luminance was observed [ F (1, 36) = 1.27, p = .27, η 2 p = 0.034; dark: M = -0.70 mm, SD = 1.57 mm; light: M = -0.79 mm, SD = 1.68 mm].
