Hi,
I am about to run the AAT and have two quick questions:
1.
Can you tell me if the value of the joystick threshold has any effect on the results recorded? Within the library script, it is set at 50 by default, but I’m not sure what this means – is itthat a response will only be recorded if the joystick is extended to ‘50’ (Iassume a midway movement), but that the response times are still recorded from when theparticipant first touches the joystick (values.RT), and when it is fully extended (values.CompleteRT)? I am using a Logitech Attack 3.
2. I want to reduce the size at which the image first appears - I know I can do that by changing the startheight ratios as follows (from .5 to .45), but I just want to make sure that doesn't effect how the script runs (times recorded etc.)
Thanks very much.
Rebecca
