I am trying to create the following experimental situation:
Present a cue stimulus for 800ms
Present a second cue stimulus for 500ms
Present a third stimulus to which the participant must respond
I created three events to represent the three stimuli listed above. However, I’m having a problem with the third event/stimulus. There appears to be some sort of delay with this event. For example, after the participant responds correctly, the stimulus stays on the screen for a little while before staring the event cycle again. This third stimulus also won’t respond to a time limit. Whether I set the stimulus to end after 10ms or 500ms, it just stays on the screen the same amount of time. Any idea what is going on?
