Hello!
I need to prepare a procedure where I will present Gabor patches in two orientations. One of them will be predetermined (45 degrees), while using the staircase (StairHandler) procedure, I would like to set the other orientation of Gabor - so that based on the subjects’ responses, they would be able to distinguish both orientations 50% of the time. However, I don’t know how to prepare the staircase procedure in such a way that only one value (orientation) is changed based on the answer, and the other (45 degrees determined from the beginning) remains the same. I will be grateful for any hints!
