Dear All,
I used the counterbalancing option (https://www.psytoolkit.org/lessons/counterbalance.html).
Is the information about the group the participant is assigned to somewhere saved in the data.xls file (or somewhere else)? I somehow assumed so, but it seems it's nowhere (also the jump command isn't logged).
In this case I can retrieve the information from a question we ask participants, but for the future this would be really interesting to know. Or do you somehow need to log this explicitly?
Kind Regards,
Andre

Hi I am experiencing the same problem. Would be happy to know the solution (if any)? If we cannot retrieve the information (namely the condition sujects were assigned to) that coding psy_group is not helpful at all. Best

As quick workarounds I could only think of the following:
- If you have an experiment in the survey, maybe you can move the variable from the Survey to the Experiment (using Var in and/or Var out functionality, although something like this hasn't worked for me in the past).
- Create a question directly asking participants for it (What kind of picture did you see? - A face - A place), but with all its 'dangers'
- To be honest, I couldn't think of anything else. I present two different types of YouTube videos, and I wasn't able to find a way how I can for example log the video URL. I also simply tried to create a variable which is then stored, but Survey's don't have variables, only Experiments. All the 'crucial' bits which might help to identify what happened (YouTube URL, jump-commands,...) seem to not be logged.
Edit:
Just thought of another thing, which should work:
If you include an If/jump command and name the questions which follow differently, you'll have it indirectly, because PsyToolKit will log those in different columns, e.g.:
- if $psy_group = 1 then goto Age_Group1
- if $psy_group = 2 then goto Age_Group2
l: Age_Group1
t: textline
q: How old are you
- Your age in years
j: Next_Question
l: Age_Group2
t: textline
q: How old are you
- Your age in years
l: Next_Question
t: ...
...
Then you should get two columns in the data.xls file, one for "Age_Group1" and one for "Age_Group2", with a data point (age) only in those cells for the group the participant is in. For all participants, the questionnaire will look the same.

Hi Andre,
I did as suggested. However it seems that this manipulation did not work.
I created two comprehension questionnaire (prior to the main variable) one for psy-group = 1 & the other for psy_group = 2, however it seems that some participant have been able to complete both questionnaires since I have values for both comprehension questionnaires in the excel file...

In particular if only some and not all participants answered both questionnaires, I'm at a loss. Sorry, no idea then either... I had this setup in my study (not deliberately to be able to split the groups, but because I asked the groups different questions) and each participant had answers only in one or the other group of questions.
If all participants always see both questions, then I'd speculate that it is a programming mistake.

Hi all,
maybe another solution would be (if you use a table in the experiment) to add another column in the table specifying the trials. You can then save the info/column from the table using the @ function.
Of course this doesn't work retrospectively, when you've already run the study.
