We are using Win10 and 1.90.1 version of PsychoPy.
We are conducting a time perception experiment. Subjects are asked to specify sound durations, which are 100, 250, 400, 550, 700, 850, 1000 ms, as being closer to short prime(250) or long prime (850). We created an excel file (conditions.xlsx (8.2 KB)) with seven conditions with different durations. We try to specify durations by writing $stop on the stop part of sound component. There will three repeats of the seven sound durations. But, when we create the loop, the experiment could not be run. It says “value error: could not convert string to float: $stop”
Could you help us solving this problem?
Thanks a lot!
