Scene-probe dynamics impacts absolute sensitivity but not differential effects.

Zooming stimuli involve smooth transitions from scenes without probes (leftmost icons in A-D) to probes without scenes (rightmost icons) in either scene-to-probe “zoom-in” direction (left to right in A-D) or probe-to-scene “zoom-out” direction (right to left). E plots sensitivity (d′) for zoom-in (y axis) versus zoom-out (x axis) configurations (blue symbols) and long-duration (300 ms, x axis) versus short-duration (100 ms, y axis) stimuli (red) using conventions similar to Fig 2E. F-G plot corresponding log-ratios using conventions similar to Fig 2F and 2G. Data for this figure is available from S2 Data.
