Review of Article on Petter’s Rule and the Support Ratio Rule
Part I: Summary
The goal of the study conducted by Singh, Hoffman, and Albert (1999) was to employ experimental methods to determine the relative contributions of two rules,
Petter’s
rule and the support ratio rule, to the phenomenon of modal completion and
amodal
completion. As Singh et al (1999) described the research question at the heart of the study, what is it that determines whether human vision will see a completed contour between given edges? The support ratio rule suggests that we complete shapes based on factors of alignment. There are two rules in this regard. First, the extensions of edges must meet, and the exterior angles of intersection must be acute; to the...
The end:
.....tle doubt in the minds of perception scholars that
Petter’s
rule is the more powerful of the two rules governing contour completion. Also, in terms of class material, we can think of
Petter’s
rule as conferring evolutionary advantage in terms of both perception and the creation of cognitive maps, accounting for the empirical result that
Petter’s
rule is more important than the support ratio rule in terms of accounting for contour completion.
