Crucial to the latter finding is the distinction between, and integration of, viewpoint-independent and viewpoint-dependent factors in vision, as proposed in SIT's empirically successful model of amodal completion.<ref>van Lier, R.

''Perception, 23,'' 883—903. {{doi|10.1068/p230883}}.</ref> In the Bayesian framework, these factors correspond to prior probabilities and conditional probabilities, respectively. In SIT's model, however, both factors are quantified in terms of complexities, that is, complexities of objects and of their spatial relationships, respectively.<ref>Ungerleider, L. G., & Mishkin, M.
