Factorial ANOVA testing interactions between factors condition (left column) and region (second column), assessing differences between neighboring regions is shown. Results for group and individual monkeys are listed. Bold indicates significance at p < 0.05 in group, and underlined indicates significance in group and in at least two-thirds of the subjects. n.s., Nonsignificant; ExCon, expansion/contraction; Transl, translation; Rot, rotation; KinSha, kinetic shape; Transp, transparent; 3D-Rot, three-dimensional rotation; 2D-Transl, two-dimensional translation.
