Lack of information integration in the absence of saccades. (A) Orientation-discrimination performance in the “both” condition as a function of the best single-cue performance (i.e., smallest SD) for each subject in Experiment 4 (no eye movements). Performance is not significantly different, providing no evidence for integration. Gray error bars: ±1 SE. (B) Performance in the “both” condition plotted as a function of the performance of an ideal integrator. For most subjects the SD in the “both” condition was greater than ideal. Gray error bars: ±1 SE.
