hello, 

i am preparing an fMRI task where the buttons on the button box are associated with particular keys. is there a way to translate the button box input to another output key in inquisit? for example, one button is 'a', and i would like to print this response as 1 (instead of 'a') on the screen (participants must see their response on the screen during the task).

thank you!

You can always use <values> and /ontrialend logic.

Particpants will see their answer being printed on the screen during the trial ("openended" trial). can i change the values before that, so the right value will be printed on screen?

No. What you can do is something like this

<values>
/ keypressed = 0
</values>

<block myblock>
/ trials = [1-4 = mytrial]
</block>

<trial mytrial>
/ ontrialend = [
    if (trial.mytrial.response == 30) {
        values.keypressed = 1;
    } else if (trial.mytrial.response == 31) {
        values.keypressed = 2;
    } else if (trial.mytrial.response == 32) {
        values.keypressed = 3;
    } else if (trial.mytrial.response == 33) {
        values.keypressed = 4;
    }
]
/ stimulusframes = [1=mytext]
/ validresponse = ("a", "s", "d", "f")
/ branch = [
    trial.youpressed;
]
</trial>

<trial youpressed>
/ stimulusframes = [1=key]
/ trialduration = 1000
/ validresponse = (0)
</trial>

<text mytext>
/ items = ("Press one of the keys 'a', 's', 'd', or 'f'")
</text>

<text key>
/ items = ("You pressed key #<%values.keypressed%>")
</text>


but if the response box sends the code for an "A", then that's what the box sends. Inquisit cannot change that.

thank you, so I would not be able to translate the button presses to the correct values with an openended trial like below?

<openended estimate_art>
/ position = (50, 50)
/ buttonlabel = "please enter estimate"
/ fontstyle = ("Arial",20)
/ inputdevice = keyboard
/ validresponse = (noresponse)
/ stimulustimes = [0=sceneStim_current, estimateQ, leftHand, rightHand]
/ linelength = 3
/ range = (0,100)
/ numlines = 1
/ responsefontstyle = ("Arial",80)
/ posttrialpause = list.jitter_estimateList.nextvalue
/ trialduration = 3000 + list.jitter_estimateList.currentvalue
/ branch = [
trial.outcome_art
]
</openended>

Correct. The bottom line is, don't use an openended, build whatever you need to build using standard trial elements.

Correct. The bottom line is, don't use an openended, build whatever you need to build using standard trial elements.

So, if you have a response box with a limited number of buttons, let's say six, you'll need to come up with a way to enable people to enter any digit between 0 and 100, such as 37. That's not doable with some simple remapping of letters to digits to begin with. Instead, you can think of building something like this:

<values>
/ estimate = 0
</values>

<block myblock>
/ trials = [1 = mytrial]
</block>

<trial mytrial>
/ ontrialend = [
    if (trial.mytrial.response == 30) {
        values.estimate += 10;
    } else if (trial.mytrial.response == 31) {
        values.estimate -= 10;
    } else if (trial.mytrial.response == 32) {
        values.estimate += 1;
    } else if (trial.mytrial.response == 33) {
        values.estimate -= 1;
    };
    if (values.estimate < 0) {
        values.estimate = 0;
    };
    if (values.estimate > 100) {
        values.estimate = 100;
    };
]
/ stimulusframes = [1=mytext, estimate]
/ validresponse = ("a", "s", "d", "f", "g")
/ branch = [
    if (trial.mytrial.response != 34) {
        trial.mytrial;
    } else {
        trial.yourestimate;
    }    
]
/ recorddata = false
</trial>

<trial yourestimate>
/ stimulusframes = [1=estimate]
/ trialduration = 1000
/ validresponse = (0)
</trial>

<text mytext>
/ items = ("a' = increase by 10
's' = decrease by 10
'd' = increase by 1
'f' = decrease by 1
'g' = submit response")
/ position = (50%, 10%)
/ erase = false
</text>

<text estimate>
/ items = ("Estimate: <%values.estimate%>")
/ erase = false
/ size = (40%, 10%)
