Dear millisecond team,
I have created a program with inquisit lab 5. The subjects received a video as a stimulus and were asked to press a button to indicate what sensations they had. I use the latency times to calculate how long they felt relaxed for example.
The video timeout was 1191000ms long in total. If I add up all the latencies of a subject, I get different values. These values are slightly shorter than the total timeout. Here are the added latencies: 1190119, 1190547, 1190959, 1190860 etc.
Can you tell me how these different times arise so that I can explain this fact in my study?
Many thanks in advance.
Kind regards, Annemarie Busch
PS.: Here are excerpts from the program so you can understand more easy what I did
