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.
