Independence of Echo-Threshold and Echo-Delay in the Barn Owl

Figure 6

Proportions of trials on which saccades were lag-directed for three birds.

(A) Proportion of lag-directed saccades in the standard paradigm plotted against the lead/lag delay. The black, dashed, line in this and other plots shows the average of all three subjects. (B) Proportion of lag-directed saccades observed when lag-alone segments were experimentally lengthened. At each point along the abscissa, the number on top indicates the length of the lead-alone segment (onset-delay). The number underneath indicates the length of the lag-alone segment. (C) Proportion of lag-directed saccades observed when lag-alone segments were experimentally shortened. (D) Proportions of lag-directed saccades shown here have been regrouped so that the length of the lag-alone segment is constant within each panel.
