Hi,
I have a few questions regarding the D value. My supervisor would like me to count the D value for the compatible block (in my case those are blocks 3 and 5) and for the incompatible blocks (in my case 7 and 9). Now, obviously, the D value for the compatible blocks is counted - this is the value in the column expressions.d in the last row of the last compatible block. However, it is not the same case for the incompatible blocks - this one I have to count by myself, right? Because the last D value of incompatible blocks is the actual D value (so the actual IAT effect).

Now, I have a question regarding interpreting the data. If the D value for the compatible blocks equals -1,4592282838115384624, then what does that tell me? Does it mean it was easier for the person to put the positive words to their own group? When is the score negative and when is it positive? How would that look for the incompatible blocks?

For the record, in my IAT it looks like this: attributes A are positive, attributes B are negative, target A is their own group, target B is the other.

Thank you in advance for the help!
