Abstract

In the present study, we examined the interactions between intrinsic (proximity and similarity) and extrinsic (common region) grouping principles. In three experiments, each principle was displayed alone or conjoined with another principle both in a competitive or cooperating way. When common region and similarity principles were used, the results showed that the grouping strength of conjoined cooperating principles was greater than the strength of either principle alone, and the grouping strength of conjoined competing principles was lesser than that of either principle alone. In contrast, when common region and proximity principles were used, the grouping effect of proximity acting alone was similar to that of competing conjoined principles. The results suggest that the interactions between grouping principles might be modulated by the relative salience of the principles acting alone.
