Figure 2. Mean distance estimates in experimenter-guided walking, expressed as a percentage of the stimulus distance.

Each data point is the mean response for one participant, collapsed over nine measurements; data for all three participant groups are shown (CONT =  age-matched healthy control; LTLR =  left temporal lobe resection; RTLR =  right temporal lobe resection). The solid line indicates the mean level of performance for each group. Error bars represent ±1 standard error of the mean.
