Participants
32 participants (17 female, age range 18 – 35 years) were recruited from Trinity College Dublin. All participants provided written, informed consent and all participants had normal or corrected-to-normal visual acuity. Participants were compensated for participating with either a of their postgraduate research degree worth 1 ECTS per half hour of participation. The study was approved by the Ethics Committee of Trinity College Dublin’s School of Psychology (approval ID SPREC052022-01). One participant was excluded from analysis due to near chance performance on the flash-fusion task at all stimulus levels. Two participants showed no alpha-band peak in pre-stimulus EEG recordings and were excluded only from the pre-stimulus analyses.
