Fig 2. Top Panel: The percentage of straight ahead responses is plotted by test body orientation with separate traces for pre-adapt, post-adapt right and post-adapt left.

Error bars show +/1 S.E.M. Bottom Panel: Mean difference in the percentage of straight ahead responses pre- and post-adaptation by test body orientation, with separate traces for adaptation to rightward and leftward facing adaptors. Error bars show 95% confidence intervals around the point estimates, the dotted black line marks an effect size of zero.
