IAT incorrect response feedback (case 24217)

[davidlau17]

I'm creating an IAT, and I want to give participants response feedback only for incorrect responses (image of a red X), and I want that image of a red X to stay on the page until they give the correct response. So even if they get the response incorrect, they stay on the same trial until they give the correct response. I'm having difficulty figuring out how to do this. Any help would be appreciated.
