Inter- and intra-hemifield pre-saccadic distractor trials. (A–C) Screen and oculomotor center representations before and after the first saccade. For inter-hemifield pre-saccadic trials (A), the distractor is presented near to the initial fixation, located in the same hemifield. Here, if oculomotor centers remap the distractor across saccades, we predicted that vertical saccades would curve away from the distractor screen position (red arrow), otherwise they will curve toward it (blue arrow). In intra-hemifield pre-saccadic trials (C), the distractor is presented further from the initial fixation position, located in the other hemifield. We predicted that vertical saccades would curve away from the distractor screen position irrespective of whether oculomotor centers remap (red arrow) the distractor across saccades or not (blue arrow). (B–D) Averaged normalized second saccade trajectory (top panels) and normalized curvature angle (bottom panels) observed following the presentation of a visual (left panels), an auditory (center panels) or an audiovisual (right panels) inter-hemifield (B) and intra-hemifield (D) pre-saccadic distractor in Exp. 1. Conventions are as in Fig. 2.
