Abstract

The encoding of shape information from spatially separate items was investigated in 3 experiments. In Experiment 1a, participants had to search for an inward-pointing are among a set of outward-pointing arcs; participants in Experiment 1b were given the opposite task. Search was efficient if distracter arcs pointed away from fixation and there was curvilinearity between neighboring end-terminators (Experiment 1a) but relatively inefficient if distracter arcs pointed toward fixation (Experiment 1b). In Experiments 2 and 3, connecting end-terminators did not change performance. Results reflect the involvement of mechanisms of shape encoding.
