Preemption Effects in Visual Search: Evidence for Low-Level Grouping

Eight experiments, each with 10 observers in each condition, show that the visual search for Mueller-Lyer stimuli is based on complete configurations rather than component segments with preemption by low-level groups. Results support the view that rapid visual search can only access higher level, mo...
