Attentional facilitation: task-relevant spatiotopic location, accuracy task. A, Experiment 2. Attentional facilitation is plotted as the difference in accuracy for masked probes appearing in the spatiotopic and retinotopic locations compared with the control location baseline (zero). Positive values indicate facilitation (accuracy better than at control locations). B, Experiment 1. RT data from the 75 ms and 400 ms probe delays of the saccade task replotted for comparison. Error bars indicate SEM after normalization to remove between-subject variability (Loftus and Masson, 1994); n = 16.
