Original script from inquisit used keyboard as an input device, and I'm trying to change input device to mouse. Scancode for space key was 57, but I can't find any scancode for mouse left button.
I tried 84 and 85, but it didn't worked.
Following is part of the original script (Go-nogo task), and it's coding correct response using scan code (0=noresponse, 57=space bar).
How can I code 'left mouse down' with a number?

There are no numerical scancodes for mouse events. What you are looking for is lbuttondown, as detailed in the documentation for the valdiresponse attribute.

Thanks for your reply!
I tried to add some text to code 'lbuttondown' for response.
Original script defines correct response with '0(no response)' and '57 (space bar)'.
If input and predefined correct response are identical , the input is marked as a correct answer.
I added underlined text to shift 'noresponse' into 0 (same as original script) , and 'lbuttondown response' into '57' and assigned them using a new value (respreal).
I ran the script, but values.respreal from data file is '0' all the time (in every trial)!
How can I fix this?
I want to assign 'lbuttondown' as '57' in values.respreal, and 'noresponse' as '0' in values.respreal.
I attached inquisit script file that I modified.

/ontrialend attributes are executed *after* response evaluation.
You need to fold the logic into the /iscorrectresponse attribute.

Thanks for reply.
I modified script as you suggested (underlined text), and I fount one problem.
I want to mark response as correct answer if
1) response is 'lbuttondown' && values.correctresp == 57
or
2) response is '0 (no response)' && values.correctresp == 0
but...inquisit marked response 'correct' when response==0 && values.correctresp ==57 (which should be marked 'wrong').
Is there anything wrong with my logic on script?

When / where do you set values.correctresp?
|
By Dave - 9/12/2014
FWIW, there's a minor syntax issue in your /iscorrectresponse attribute. It ought to read
/ iscorrectresponse = [(trial.target.response=="lbuttondown" && values.correctresp==57) || (trial.target.response=="0"&& values.correctresp== 0)]

Thanks a lot!
Problem solved!
