Multiple responses for a single trial

    Multiple responses for a single trial

    I am creating a project where I would like to give the participants three chances to respond to my stimuli in one trial. The participant is shown a prime face and then a target picture, followed by a visual mask for 150ms. This needs to be followed by a red cross for 450ms to tell the participant that they are running out of time, and a gray cross for 500ms to tell them they are on their final amount of time. I would like them to be able to respond during any of the three images (visual stimuli, red cross, and black cross), so they have a total of 1100ms to repond. However, if they do not respond on the Visual Mask or the red cross I do not want the program to flash the "Please respond faster" message on the screen, instead I just want it to move directly to the next stimulus. Can this be done?
