I know this has been discussed before, but I'm hoping someone can just confirm that this is the correct way to interpret the d score (expreesion.d) in a single target IAT.

Higher scores indicate faster performance when the Target is paired with Attribute A (and lower scores would be faster performance when the target is paired with Attribute B).  Is that correct?

Thanks!

The interpretation is exactly the same as in a regular, two-target-category IAT. You can think of the Single-Target-IAT as a regular IAT where target A = whatever your target concept was and target B = nothing.
