I am trying to set up an event or multiple events that will result in the following:
During a 7 second delay, during which the screen is just black, participants can press the space bar as many times as they would like, and each space bar press results in a pulse. After the 7 seconds is over, they are then asked to type in a response.
I can get the delay, and I have figured out how to get one pulse, but I cannot figure out how to get multiple pulses to result from a free response.
Please help! Thanks!!!
