Figure 5.

Value of the weighting parameter, α, determined by fitting the weighted COG model (see eq. 1 and Appendix) for all 3 observers as a function of either critical frame duration for the masked condition (Experiment 2a) or the average saccadic latency for the no-mask condition (Experiment 2b). Higher values of α indicate that results were better accounted for by assigning a greater weight to target discs. Target elements were to the left or right of fixation.
