Performance on the buzz-wire task, for monocular versus binocular viewing. (a–d) Performance on four different metrics, with binocular viewing (“Binoc”), or monocular viewing with the dominant eye (“Dom”) or non-dominant eye (“Non-dom”). In every case, binocular performance is significantly better than either monocular condition. (e) Binocular advantage, i.e. ratio of the metric in the monocular-dominant condition to that in the binocular condition, calculated for each subject individually and then averaged over all 40 subjects. Other details are as in Figure 2.
