The observed difference in means of 1.31 s ( M MARM-D1R = 1.31 s, SD MARM-D1R = 1.04 s; M MAC-D1R = 2.62 s, SD MAC-D1R = 0.75 s) was highly significant ( p = 0.0001), indicating that mean fixation duration in the marmoset-D1R model was significantly shorter than in the macaque-D1R model (Fig. 8B2 ).
