I’m new to SuperLab and I’m trying to create a simple reaction time experiment in which a participant must respond to a stimulus (Stroop word) presented for 500 ms. I want the stimulus to appear then disappear from the screen and then give the participant an additional 1500 ms to respond. Thus, one trial lasts for a total of 2000 ms. My problem is that I want this to all occur as one event such that the participant can respond at any time during the 2000 ms interval, including when the stimulus is present. I was able to create two separate events (one for the stimulus onset/offset and another empty interval for the additional 1500 ms). The only problem is that when I go to analyze the data on a given trial I see a NR for one of the two events and the correct RT for the other event. So, technically this experiment works, but I was just curious if there is a way to do it all as one event so I won’t have to manually sort through the data eliminating the NR’s?
