I am trying to create a visual lexical decision experiment where some words are presented with degradation and other words are presented normally. I am having problems introducing the degraded stimuli in psychopy. The degradation involves reducing the contrast of the word (grey words on black background vs. the normal condition with white words on black background.
I figured out how to change the text color and background color in coder, but it changes all words instead of some. I also tried an if-else statement (including a condition ‘degrade’ in the .csv file) but it didn’t change the color at all (I put it in the front of the routine and just before the stimulus object is drawn and many other places but to no avail). If anyone has any ideas as to how to go about this I would be very grateful!
