I want to create an attentional blink task. The two targets will be colored with red. Since the stream sequence is random, that is the target position is randomly assigned.
Using the above codes, I have successfully defined these target colors. However, when trying to display the targets in sketchpad, it reports that the result_color is not defined.
I also attached my experiment code, in case I didn't explain it clearly.
Could you please check and tell me what happened.
