Parameters (slope, intercept) of the best fit straight lines for scatterplots of saccadic landing position vs. the center of gravity of the target discs, when target discs were presented alone and with interleaved distractor discs. Numbers in parentheses denote 95% confidence intervals. Stimuli were not masked. Trials were divided according to saccadic latency; ‘Short’: latency < 180 ms and ‘Long’: latency > 180ms.

SD is the root mean square error (RMSE).
