[open] Joystick away/toward and RT

Iluas

Hi everyone,

For my first experiment with open sesame I'm creating an approach/avoidance test with a joystick.
Unfortunately I have few knowledge about python despite the fact that a friend of mine thought me the fundamentals.

Here is my protocole:
After being exposed to an odorant prime, the participant have to press a joystick button (2) to start the stimuli display
Then a set of simple geometric shapes (square and circle) appears on the screen.
For each of them the participant have to pull or push the joystick as response (counterbalanced of course).

I would like to log the response (0: pull ; 1: push) and the reaction time (between the stimulus display and the start of movement).

This is a first try to code this but it sends me an error message "ImportError: No module named libjoystick":

Any help will be very welcome.
Thank you very much

Adrien

Hi Adrien,

Have you included a joystick item in your experiment? The libjoystick library isn't activated until a joystick item is prepared. You can insert one at the start of your experiment, e.g. to catch a buttonpress after showing an introduction. Alternatively, you could set the Run if to never (as it only needs to be prepared, not actually run).

Good luck and happy holidays!
