Hey everyone,

so as I am still new in Inquisit I have another "problem" that I can not solve.

To put it in a nutshell: I have two blocks. Within a block there is at trial being repeated until the participant answers in a specific way. To be more precise: The possibilities for answering are "yes" and "no". If the participant answers with "yes", the block will be ended. But if his answer is "no", then the trial will keep being repated until he says for the first time "yes".

To achieve that I have chosen to use radiobuttons as you see ahead:

<radiobuttons q1>
/caption = "..."
/fontstyle = ("Times New Roman", 3.00%, false, false, false, false, 5, 1)
/options=("yes", "no")
/optionvalues = ("1", "0")
/orientation = vertical
/position = (10,20)
/required=true
</radiobuttons>

<surveypage q1_page>
/caption ="..."
/ fontstyle = ("Times New Roman", 4.00%, false, false, false, false, 5, 1)
/itemfontstyle = ("Times New Roman", 2%, false, false, false, false, 5, 1)
/responsefontstyle = ("Times New Roman", 1.5%, false, false, false, false, 5, 1)
/ txcolor = (0, 0, 0)
/questions =[1=q1]

/nextlabel = "Weiter"

/nextbuttonposition = (70%, 60%)
/ finishlabel = "Weiter"

/showpagenumbers = false
/showquestionnumbers = false
</surveypage>
...
<block b1>
/ trials = [1= t1; 2-200= t2]
/ stop = [radiobuttons.q1.response == 1]
</block>

But now I want to change that to save time. So I don't want the participants to see a radiobutton question and answering with yes or no. Instead I want them to press two keys on the keyboard, for example "<" for "no" or "-" for yes". So he just needs to press one keys to end the block (with "-" for "yes"). If he choses "<" the trial will be repeated ( / trials = [1= t1; 2-200= t2]) etc. 
  To achieve that I tried to use the following (with 1 representing yes and 2 being äquivalent with 0) hoping that 1 would end the trial (and block)

<trial q1>
/ stimulusframes = [1=white; 2=text, p]
/correctresponse = ("1")
/ validresponse = ("1", "2")
/ posttrialpause = 500
/branch = [if(trial.q1.response == 1) trial.painadjust_t_th1]
</trial>
...
<block b_1>
/ trials = [1= t1; 2-200= t2]
/ stop = [trial.q1.response == 1]
</block>

But it just does not seem to work.. First problem is that I just am able to use the digits on the keyboard. Then the trial won't end - independently of using 1 or 2.....

Do you guys have any ideas how to manage the problem? Or have an inquisit script example? Thank you so much in advance!


Regard and thank you,
