Continuation even if there is no keypress?
I have created an experiment with OpenSesame, in which the participants have to react to auditory stimuli by pressing a key. I have set the duration of the SAMPLER item to 'keypress'. However, the participants have been instructed to not press the key on certain occassions. Given the fact that the experiment will not continue if no key is pressed, I was wondering how would it be possible a 'None' response to be also allowed.
Thanks in advance for every help.
