Confirming the superiority of the lateral shift-plus-repulsion model, likelihood ratio tests (see the electronic supplementary material, Methods) for the lateral shift and repulsion models relative to the lateral shift-plus-repulsion were highly significant for all participants (the largest probability was for participant BO for the comparison of repulsion versus lateral shift-plus-repulsion: p = 0.02, χ 1 = 5.41).
