^aData are mean ± SEM. Results from the local and global tasks at each coherence value (Experiment 3), replicating the findings of Experiment 1. Reaction times are shorter in the global task. An ideal observer without any imbalance in accuracy between tasks would have shorter reaction times in the global task. There are more interference than symmetrical errors in the local task.
