Abstract

The present study examined the influence of perceptual organization on the processing of global and local information in hierarchical patterns. In two experiments, we examined whether disturbing the spatial relationships between local elements by introducing between-element distance and size heterogeneity affected global processing dominance. The effects on global processing dominance of undistorted compound stimuli with equidistant and homogeneous local elements were compared with those of compound stimuli which presented between-element distance heterogeneity (Experiment 1) or heterogeneity in size (Experiment 2). The results showed that the global advantage effect decreased similarly under conditions of between-element distance and size heterogeneity that disturbed the spatial relationships between local elements. The results provide new evidence on the role of perceptual organization in hierarchical patterns processing.

1
A reviewer suggested the possibility that a coarse distribution of the local elements could be the responsible factor for the decrease in the global advantage effect in Experiment 1 as well as in Experiment 2. However, this possibility could be discarded by data obtained in another experiment in our lab, showing that the increase in the distance between local elements regularly spaced did not affect the global advantage effect. We are currently examining whether the increase in the distance between local elements irregularly spaced affects global advantage.

The main difference between our study and that of Hoffman is that in his experiment the distortion of the global form consisted in moving one local element to an unusual location (out of the contour of the global form), whereas in our experiments the spatial relationships between the local elements (and their perceptual organization) were manipulated inside the contour of the global form.
