I am programming an approach-avoidance task in which participants receive visual response feedback - e.g. the background image and stimulus size changes to create the impression of approaching or dtsiancing themselves from the stimulus (by moving within a virtual room)
Unfortunately, the beginning of each trial always comes with a short flicker which highly disturbs the desired visual illusion. this seems to only happen, when i use an image for the background, not when I use shapes defined within inquisit, so it may be related to the loading time of the image (?).
Any idea what I can do to avoid this?
