Figure 2. Behavioural tasks.

Figure 2

Top, forced-choice (FC) task. After a fixation period, a saccadic target appeared in one of the two positions in one of the hemifield. Trials in which stimuli were presented in different hemifields were in different blocks. Bottom, Yes-no (YN) task. The ST+ condition (“YN ST+”) was identical to the FC task. Trials without a saccadic target (ST− condition) were randomly interleaved. The ratio for ST+ condition (p %) was fixed as 30% in the results for Fig. 3 and varied across trial blocks in the results for Fig. 4.
