WebMar 5, 2024 · Figure 1. Experimental paradigms. (A) Each trial in the pro- and anti-saccade task with emotional auditory stimuli began with the appearance of a central FP on a background (Dark: 2 cd/m 2 or Bright: 16 cd/m 2).After a 500 ms delay, an emotional auditory stimulus was presented for 6 s, followed by the presentation of the instructed … WebWhen the participants were required to either detect (Experiment 1A) or localize (Experiment 2A) a target, the magnitude of IOR was unaffected by the presence of a fixation cue. In contrast, when the participants were required to identify a target (Experiments 1B, 2B, and 3), IOR was observed only when a fixation cue was presented.

WebJan 24, 2024 · Motor imagery-based brain-computer interfaces (BCIs) have been studied without controlling subjects’ gaze fixation position previously. The effect of gaze fixation and covert attention on the behavioral performance of BCI is still unknown. This study designed a gaze fixation controlled experiment. Subjects were required to conduct a …
WebNov 12, 2024 · In exogenous attention, two main behavioural effects are usually observed across time: facilitation at short cue-target onset asynchronies (CTOAs), and Inhibition of Return (IOR) at longer CTOAs. The presentation of an intervening event (IE)—i.e., a cue presented at fixation between the peripheral cue and target period—favours the …
WebAfter 500 ms of fixation, the fixation point changed to a horizontal (0.4 by 0.2°) or vertical (0.2 by 0.4°) fixation bar which served as task rule-cue for the current trial.
