keyboard response in the Gaze Cueing Tutorial
Hello, I'm brand new to OpenSesame and this forum. I completed the Gaze Cueing Tutorial exactly as the instructions describe and it runs ok, except the keyoard_response object doesn't seem to work right. In this experiment, the participant is supposed to respond to the target by pressing 'z' or 'm'. If I press either letter twice in quick succession my second response is collected (with a super short RT because I just double-tapped). But surely that isn't what the designers of the tutorial intended? If I only press the response key only once, no response is recorded and the trial times out with the 'incorrect_sound' playing.
Can anyone explain what's going on? Is there an easy fix or do I really have to create my own custom inline structure (I can can program a little but don't know Python) just to record keyboard response times properly?

Hi @jadewey,
The experiment described in the tutorial should be working fine. I think there must be something you missed. In the task as described in the tutorial, there is only onw keyboard object within a trial, hence there should be no opportunity to make two fast responses and have the second recorded. My guess is that you did not set the duration of the target sketchpad to 0 but left it on "keypress" or some other value. Can you check? Else, please upload your implementation of the task so we can have a look to see what the problem might be.
Best,
Fabrice.

Your guess was correct! Thanks so much, it's working now.
