(Left) Depiction of target visibility manipulations used in experiment 3. Horizontal bars indicate the location of the walker’s COM when the target of the corresponding color was visible. Vertical bands indicate hypothesized critical control phase for each target. Target visibility manipulation was applied to either target 4 or target 5. (Right) Mean absolute stepping error relative to full vision control condition and 95% CI for each condition in experiment 3.
