Hi,
I am trying to program a simple task. Images are presented one at a time for 400 ms each. They are separated by 200 ms blanks. Sometimes, an image is repeated twice in a row. When that happens, participants need to press the space bar. Any response that is recorded up to 3 seconds after the presentation of a repeated image is correct.
What I did is that I created different trials for each image and each blank. I used the min/max option (0-400 ms for images and 0-200 ms for blanks) and indicated "rt:57,-1,full" in the time column. I indicated that intervals should be of 0 ms.
My problem is that DirectRT does not always record my responses. My hypothesis is that it does not record a response when it is made between trials (i.e., during the intervals that must last at least 60-70 ms). Could that be right? If it is, do you have any suggestions about how I could program the task differently?
Thank you very much!
Catherine
