I’ve designed a Stroop task that closely adheres to the parameters of the children’s color-word Stroop. Because I wanted to be sure the stimuli were presented exactly as presented in the paper version, I did not use a simulus list or randomize the trials. Instead, I created a trial with many events, each of which should - ostensibly - provide feedback if the participant doesn’t touch the correct key in response to the stimulus. The trouble I’m having, however, is that several of the events don’t provide feedback - even though I set them up the same way as the ones that ARE giving feedback. I have gone back to ensure that the feedback rules are consistent…but still, when I run the test myself, I seem to be able to push any key sometimes and the stimulus will advance to the next event, even though it should actually present the same stimulus until I get it right.
I’m wondering if this has anything to do with the fact that I copied the events and then changed the input and feedback parameters? Should this matter?
Thanks for any help you might be able to provide!
