Stimulus presentation after response
I have a response time experiment during which participants need to indicate via their keyboard whether a triangle that appears on the screen is to the left or right of a fixation point. Currently, after they respond, the fixation point appears again and after several miliseconds another triangle appears.
Is it possible to ensure that that after they provide a response, the triangle will stay on screen for a set duration regardless of their response time? Only after that time, the fixation point and the next triangle appear (again for the same fixed time), while still logging their response times for each triangle?
