Response time


Sorry if I've missed this somewhere, but how is average_response_time calculated? I have a task with multiple trials in which participant listen to a stimulus and see images before choosing a matching image.

Are the average response times calculated as the ms from the onset of the trial? If I wanted to work out the onset of the audio how could I do that? In other words, I want to know how long after the audio they responded. I'd also like to know how long in total each trial was. This way I can compare trials with differing lengths of audio. Is this possible? I extracted all variables but couldn't see a timestamp for start of trial or audio, or end of trial.

Thanks for your help!! :-)
