Any chance you can explain what the following variable names  on the WSCT  data refer to please? I am familiar withall the other data fields just not what the following refer to:

valueserror_C1  
valueserror_F1  
valueserror_N1  
valueserror_C2   
valueserror_F2  
valueserror_N2  
expressionsDiff_C1F1   
expressionsDiff_F1N1   
expressionsDiff_N1C2   
expressionsDiff_C2F2   
expressionsDiff_F2N2

I searched the literature and the two variables I need are

1. Categories completed (which is there)  and
2.
Perseverative  errors.  - this is not in the data. There is 
Sum_PerseverativeResponses but this refers to a different thing.

I
have looked at the research and also the WCST manual and have also
talked to a clinical neuroscience professor who often uses the WCST and
they can not make sense of this either .

Please help    

Thank you,

Prue 

Those are explained throughout the comments in the script:

%error_C1/.../%error_N2:                                                percent errors in the first color category ....percent errors in the second number category (etc.)

Diff_C1F1 etc.:                        difference scores of percent errors in adjacent categories

Thank you for your swift reply.   May I ask  where can I locate the  "comments in the script"

Open the the WCST script in Inquisit (or any other text editor): There they are.

ok will do. Thank you very much
