keypress or timeout
(I hope I posted this in the right section)
The goal is that the participant to be able to respond during the stimulus onset while collecting the "right" reaction time. So, I used 2 keyboard for that.
I worked from a script proposed in this discussion: https://forum.cogsci.nl/index.php?p=/discussion/312/solved-keypress-or-time-limit
In this present experiment stimuli are displayed for 200 ms and 4000 ms are available for response.
I wanted to make sure that this method is right for you ?
