[solved] no response in psychopy
Hey,
my experiment requires participants to press the left button or the down button as soon as possible when a search display appears. Everything works perfectly in legacy backend. However, it appears that these buttons are not responsive in psychopy backend.

Hi Dirk,
Keyboard presses are not always identified exactly the same across back-ends. The 'List available keys' button in the keyboard_response item therefore contains a list of all available keys adapted to the back-end you're using.
To start with, you could append a temporary feedback item to your trial sequence (place it after the keyboad_response item) to inspect how the keyboard presses are identified in your experiment. This can be achieved by simply showing the variable 'response' in the feedback item by using the square-bracket method, like so:
I hope this helps you in figuring out what's going on. If the problem remains, you could perhaps provide us with some more information (the version of OpenSesame you're using, the operating system you're running it on) and we can have a closer look at it.
Best wishes,
Lotje

Thanx for your response. In the end it appeared really easy to solve the problem. In psychopy it works if I change the allowed responses to small letters in stead of capital letters. Thus left in stead of LEFT (even though according to the list of available keys both should work).
