Back buttons in a trial

inquisituser22 — Mon, 25 Feb 2019 12:22:53 GMT

Hello,
I would like to add a back button for participants in my experiment to return to former pages to reference them for information. Here is my current script, which instructs participants to press "space bar" to advance through the pages, so I just need to add something for going back through pages.

Thank you very much!

<trial Psych>
/ stimulusframes = [1=Psych]
/ correctresponse = (" ")
/ validresponse = (" ")
/ response = correct </trial>

You can do that like so:

<values>
/ itemnumber = 1
</values>

<block psychblock>
/ stop = [
values.itemnumber >= 5;
]
/ trials = [1=Psych]
</block>

//press space to advance, press backspace to go back
<trial Psych>
/ ontrialend = [
if (trial.Psych.response == 57 && values.itemnumber < 5) values.itemnumber += 1;
]
/ ontrialend = [
if (trial.Psych.response == 14 && values.itemnumber > 1) values.itemnumber -= 1;
]
/ stimulusframes = [1=Psych]
/ validresponse = (57, 14)
/ branch = [
trial.Psych;
]
</trial>

<text psych>
/ items = psychitems
/ select = values.itemnumber
</text>

<item psychitems>
/ 1 = "Page 1"
/ 2 = "Page 2"
/ 3 = "Page 3"
/ 4 = "Page 4"
</item>
