Shift in saccade landing from target location as a function of saccade onset for eight observers. Data are collapsed across all conditions (i.e., target location, reversal direction). Note that here positive values indicate a perceived position shifted in the reversal direction, whereas negative values indicate a perceived position shifted in the opposite direction. Linear and logistic fits of the data were calculated and are overlaid as solid and dashed lines, respectively. The dotted line indicates the extrapolated position of the target: its position had it rotated with the annulus.
