As per previous investigations of visual performance fields [5] , [8] , we first conducted a 2 (Head Posture) * 2 (Distractor Orientation) * 8 (Target Location) omnibus ANOVA on these transformed values averaged over participants, which confirmed main effects of Head Posture ( F (1,3) = 13.474, MSE = .139, p = .035, η 2 = .818), and Location ( F (7,21) = 11.521, MSE = .427, p <.001, η 2 = .793), but only a marginal trend for the main effect of Distractor Orientation ( F (1,3) = 6.104, MSE = .841, p = .09, η 2 = .670).
