Hello!
Firstly, thank you to those who gave me help on my last post- it helped enormously!
I now have all of my data in SPSS, and have applied the syntax so it's in D_biep etc, and I've just stated running some analyses on it.... now maybe it's just that the measures don't correlate, but when I try to correlate D_biep (from an IAT measuring attitudes to mental illness) with my measure of explicit attitudes, there is no relationship at all!! Do I need to do anything to the data? Right now it's all values from -2 to +2.
Any help would be massively appreciated!

Hi Gemma,
note that any linear transformation like, for example,
D_biep' = 16 * D_biep + 400
will never alter the size of the correlation of D_biep with another variable. What might change is only the sign of the correlation, say, from +.37 to -.37. The same holds for the explicit attitudes scale values. Hence, it is highly unlikely that a simple transformation suffices to produce a different correlation between the two variables.
Since the explicit attitudes scale values appear to be straightforward to me, my suspicion would be that either the D_biep did not calculate properly or there really is just no relationship between the two measures. BTW, is the computed correlation exactly zero (0.0) or close to zero?
Bye, Malte.

I might add that you should be able to rule this out by comparing the D-scores computed by SPSS to the D-scores computed by Inquisit. If everything went well, they should be virtually identical.
