Fixation cue

WebTo clarify the role of the fixation cue in inhibition of return (IOR), the present study compared four conditions: fixation cue immediately after the peripheral cue, in the middle of the stimulus-onset asynchrony (SOA), immediately before the onset of the target, or no fixation cue. With a 200-ms SOA, less IOR was found when the fixation cue was either … WebThe sequence of events is the same as those without a fixation cue except for the presentation of a second central cue at fixation between the onset of the peripheral cue …

WebMay 25, 2013 · In most studies using an intervening event (called a “fixation cue” or “cue back”), it has been assumed that this fixation cue captures attention and reorients it back to fixation, leading to an earlier appearance of IOR because the disengagement of attention is anticipated (MacPherson et al., 2003; Pratt & Fischer, 2002). WebIn this case, an arrangement is needed to switch from the attentional concentration of the task fixation cue to the forthcoming stimulus. Therefore, hippocampal activity preceding stimulus was enhanced on those stimuli where processes arranged for the presentation of the fixation cue and resulted in a reasonably optimal preparative status.
