I want to present a blank screen for 5 minutes, during which the participant's response is recorded (no problem here). But then I need 10 different "probes" to pop up DURING this 5 minute event. This will consist of some text, asking a question which the participant needs to answer. Following the probe and the participant's response, I need it to go back to the blank screen. Each of the probes need to appear a certain time after the beginning of the block.
I tried to do this using multiple events, with alternating "blank screen" and "probe" events, but I am having trouble with the timing, as I can only get the event to appear for a certain period of time or following a response from a participant, I cannot seem to get the block timing to interrupt the event at the end of 5 minutes.
Does anyone know if this is possible and how I could go about it?
