Participant likert scale

[Michiel Spape]

Hi Neil,
So, if I'm correct, this should be it, let me know if I forgot something. Add the following to some procedure:
1. TextDisplay, I'm calling it question. You can insert the question here ("how guilty") etc.
2. Inline with code:
dim myNRESP as integer 'initializes an integer
myNRESP = -1 'sets it to -1, for reasons that should be clear later
3. Label, called PreJump
4. Inline with code
myNRESP = myNRESP + 1 'adds 1 to number of responses - the baseline of your code
c.SetAttrib "NRESP", myNRESP 'saves the number of responses
5. TextDisplay, I called it ResponseDisplay. It displays the following text [NRESP] (after the attribute created earlier); a maximum duration of whatever you'd like to be the final duration of your responses hammering (I made it 1000 ms here, default). An input object (I used my keyboard, any button allowed). And most important: end action: jump to label: PreJump.

Voila - tested, works. Only thing to do is dump all this in a list and add your likert questions.
Cheers,
Mich

Hi everyone,

I'm quite new to this and am about to do my first fMRI study. I
basically need to ask participants to provide feedback of how they are
feeling whilst in the scanner. However, due to being in an fMRi, they
can't talk or move, except they have a button in each hand.

Ideally I would like to be able to ask them e.g. 'how guilty do you
feel right now' and have a '0' appear in the middle of the screen.
They then click the right button from 1-7 times to let me know how
guilty they are feeling at that instance. If possible, I would like it
to somehow loop, so that if they by accident push the right button 8
times, it just loops back to 0. It would be good if they could then
confirm (terminate the slide) with the left button.

As I'm not working the with fmri for another couple of weeks, it would
be good if I could have a practice with this using two buttons on a
keyboard, but I've no idea where to begin.

Any help welcome!

Cheers,
Neil
