Attentional Capture and Inhibition of Saccades after Irrelevant and Relevant Cues

Figure 1

Depicted are examples of a different-position (DP) trial with a relevant cue (in the upper right), a same-position (SP) trial with a relevant cue (in the upper left), a different-position (DP) trial with an irrelevant cue (in the lower right), and a same-position (SP) trial with an irrelevant cue (in the lower left). In each of the four depicted conditions, the first (lower) display was the cue display, in which a color singleton cue (illustrated as a green or blue shape-8) was presented. The second (middle) display was the discrimination display where participants had to memorize the identity (i.e., shape-E or shape-3) at the position of a relevant cue (here: green) but not after an irrelevant cue (here: blue) in the first display. Alongside the discrimination target, we presented a red color singleton as a saccade cue. The third (upper) display was the saccade display; participants had to saccade to the target ring at the position cued by the red singleton. The arrow illustrates the temporal sequence. Stimuli are not drawn to scale. ISI = interstimulus interval.
