Over the last decades, vision research has seen a renewed interest in Gestalt psychology and perceptual organization. One of the milestones in this evolution is the study by Kubovy and Wagemans (1995) which revealed that the probability of grouping elements can be quantified as a decreasing exponential function of the distance between those elements (“law of proximity”) and has been the starting point for extensive research e.g. using competing grouping principles. However, the stimuli of this research have too often been limited to dot lattices with little to no element variation. To fill this gap, in this study in addition to proximity manipulation, shape variation was added to the dot lattice elements (by employing the OCTA Toolbox). Special attention was given to alignment of the shape axes with the global orientations in the dot lattice which could cause interference. Ellipses were included as a neutral condition as well as tilted squares and triangles which lacked alignment with any global orientation. Upright squares were aligned with the vertical and the horizontal orientations while triangles were either base-aligned with the shortest orientation (a-alignment) or the longest orientation (b-alignment), thereby possibly inducing pointing bias. To integrate individual trends, this research used Bayesian Hierarchical modelling. On a group level, the proximity effect was replicated. When integrating individual differences, a significant interaction was found between a-aligned triangles and proximity. This seems to support interference of pointing bias and proximity in some, but not all participants.
