In this task we want to:
Find each participant’s perceptual threshold using an adaptive staircasing procedure (PsychoPy’s quest handler).
Have noise added and subtracted iteratively from the image in this staircasing in order to determine levels at which participants can correctly identify faces at a set percentage accuracy.
Use the threshold values to have participants make cued perceptual decisions about the faces
