I did multiple administrations of the IAT per subject. 4 to be exact. I was trying to see if I could get more accurate results after multiple trials. I also used within-subject and between-subject counterbalancing. For example, Subject 1 did 4 trials; order 1, order 2, order 1, order 2. Subject 2 did 4 trials; order 2, order1, order2, order 1. to get around the automatic counterbalancing of Inquisit. I labeled subject 1-order 1, 101, subject 1-order2, 102, subject 2-order2, 202, subject2-order1, 201. This way I maintained an entire counterbalanced sample based on the order of the subjects' initial IAT as well as counterbalancing within to see if there was difference within or if i could get a mean or aggregate score that is more representative of each subject.
Anyway, I recently tried to use SPSS syntax for my IAT data. The problem i encountered is I am not sure what SPSS did with the multiple administrations because there each subject number, eg 101, which should have two scores, only has one score. I'm wondering if there is a way to change the syntax to reflect the multiple administrations, or like i have though, have to relabel my subjects to reflect each individual trial in some sane way.
