Hi Blair,

The ML/DRT combo you suggested was useful, but now I have a new task and again find myself stumped. I did a search for "probe," but haven't found anything that addresses my problem.

Basically, I need to run the primary task through DRT, not ML, because each trial has multiple events that need to be time-controlled. More specifically, I have a sequence of 5 image stimuli with a total presentation time of 5 seconds. I want to add an auditory probe that has a duration of 500 msec and is presented at intervals of 750-1250 msec, to which participants will respond by speaking into a microphone. (Participants will not respond to the images.)

So, I need to present multiple image files and have auditory probes coming up at variable intervals, and I need to record auditory responses to each of these probes. Is this possible?
