Abstract

The perceptual processing of arrows and triangles and their component angles and lines is explored in a number of different tasks.The results suggest that some analysis of shapes into simpler parts occurs preattentively, because these parts can recombine to form illusory conjunctions when attention is divided. The presence of emergent features such as closure or arrow junctions, was inferred from predicted correlations in the pattern of performance across tasks and across individual subjects.
