Action (pressing a button) linked to a specific block

NinaBergner — Thu, 03 Dec 2020 18:28:23 GMT

Hi Dave!

I have difficulties linking a button press to a specific block. If participants click on 'YES', they should be directed to block2 (the one that comes after the block Buttonpress); and if they click on 'NO' that they should be directed to block3 (the block that comes after block2). How do I achieve this?

<text Yes>
/items = ("Yes")
/position = (75%, 93%)
/ fontstyle = ("TimesNewRoman", 1.75%, false, false, false, false, 5, 1)
/ txcolor = (white)
/txbgcolor = (black)
/size = (15%, 10%)
/ vjustify = center
</text>

<text No>
/items = ("No")
/position = (25%, 93%)
/ fontstyle = ("TimesNewRoman", 1.75%, false, false, false, false, 5, 1)
/ txcolor = (white)
/txbgcolor = (black)
/size = (15%, 10%)
/vjustify = center
</text>

<trial Buttonpress>
/inputdevice = mouse
/stimulusframes = [1 = Buttonpress, Yes, No]
/validresponse = (Yes, No)
?
</trial>

<block Buttonpress>
/trials = [1 = Buttonpress]
</block>

Thank you in advance,

Nina

You need to eiher /branch from <block Buttonpress> to the appropriate follow-on block based on the trial's response or alternatively define appropriate /skip commands in block2 and block3.

The /branch variant:

[code]<text Yes>
/items = ("Yes")
/position = (75%, 93%)
/ fontstyle = ("TimesNewRoman", 1.75%, false, false, false, false, 5, 1)
/ txcolor = (white)
/txbgcolor = (black)
/size = (15%, 10%)
/ vjustify = center
</text>

<text No>
/items = ("No")
/position = (25%, 93%)
/ fontstyle = ("TimesNewRoman", 1.75%, false, false, false, false, 5, 1)
/ txcolor = (white)
/txbgcolor = (black)
/size = (15%, 10%)
/vjustify = center
</text>

<trial Buttonpress>
/inputdevice = mouse
/stimulusframes = [1 = Yes, No]
/validresponse = (Yes, No)
/ inputdevice = mouse
</trial>

<block Buttonpress>
/trials = [1 = Buttonpress]
/ branch = [
    if (trial.Buttonpress.response == "Yes"){
        block.block2;
    } else if (trial.Buttonpress.response == "No") {
        block.block3;
    }
]
</block>

<block block2>
/ trials = [1=mytrial]
</block>

<block block3>
/ trials = [1=mytrial]
</block>

<trial mytrial>
/ stimulusframes = [1=mytext]
/ validresponse = (0)
/ trialduration = 2000
</trial>

<text mytext>
/ items = ("This is <%script.currentblock%>")
</text>

<expt>
/ blocks = [1=Buttonpress]
</expt>[/code]

The /skip variant:

[code]<text Yes>
/items = ("Yes")
/position = (75%, 93%)
/ fontstyle = ("TimesNewRoman", 1.75%, false, false, false, false, 5, 1)
/ txcolor = (white)
/txbgcolor = (black)
/size = (15%, 10%)
/ vjustify = center
</text>

<text No>
/items = ("No")
/position = (25%, 93%)
/ fontstyle = ("TimesNewRoman", 1.75%, false, false, false, false, 5, 1)
/ txcolor = (white)
/txbgcolor = (black)
/size = (15%, 10%)
/vjustify = center
</text>

<trial Buttonpress>
/inputdevice = mouse
/stimulusframes = [1 = Yes, No]
/validresponse = (Yes, No)
/ inputdevice = mouse
</trial>

<block Buttonpress>
/trials = [1 = Buttonpress]
</block>

<block block2>
/ skip = [
    trial.Buttonpress.response == "No"
]
/ trials = [1=mytrial]
</block>

<block block3>
/ trials = [1=mytrial]
</block>

<trial mytrial>
/ stimulusframes = [1=mytext]
/ validresponse = (0)
/ trialduration = 2000
</trial>

<text mytext>
/ items = ("This is <%script.currentblock%>")
</text>

<expt>
/ blocks = [1=Buttonpress; 2 = block2; 3 = block3]
</expt>
[/code]
