I am working on a task in Open Sesame using a Tobii 150 Pro Spectrum to collect pupil size and a srbox to collect the responses (RT and accuracy). The task is the AX-CPT and consist in responding YES every time you see the AX sequence on the screen and NO for any other letter sequence presented. I've assigned the bottoms 1 and 5 in the bottom box as the allowed key responses: the bottom 5 is for YES and bottom 1 is for NO and depending if the participant’s number is even or odd is the other way around. I have some doubts concerning the integration of the srbox in my experiment and would appreciate any help.
1) Normally, during the calibration period I have to press space bar in order to move on with the calibration, however I am not using a keyboard, only the srbox. Can I perform the calibration using the srbox instead? How can I change this?
2) In the practice loop, I have a feedback item which is giving me the correct RT but it is not computing accuracy properly (is coming out 0 all the time). Any idea why is this happening?
3) In the output file from the experiment I’ve got no responses collected from the srbox, so although in the feedback RTs are apparently being recorded correctly, the output file is giving me nothing.
4) If I am not using a keyboard, only the srbox, how can I can I stop or quit the experiment?
Attached you can find the experiment and the output file.
Many thanks in advance!
