| Summary: | <p>Depicted is the experimental design of a trial from the multiple distractor condition. While the cue was specified within the auditory modality, target and distractors were presented in an RSVP stream. The only factor distinguishing target from distractor stimuli was the variation in timing of their presentation: distractors were presented before the cue onset, whereas a target could coincide with (SOA = 0 ms, as illustrated here) or shortly follow the cue (SOA = 300 ms). Visual stimuli were incorporated into an RDK, characterized by two overlapping motion planes moving in opposite directions. On the right ear, participants were exposed to a series of pure tones, while a continuous tone was played to the left ear. The cue was identified as a brief increase in amplitude (+10 dB) in the continuous tone. The visual target event was marked by the alteration of green dots, transitioning from a circular to square shape (for 100 ms). RSVP = rapid serial visual presentation, SOA = stimulus-onset asynchrony; RDK = random dot kinematogram.</p> |
