Thanks Dave. Having read the link the answer is yes, the summary d score does use the amended algorithm.

Hi, can anyone help with this question.....
I want to know whether the D scores computed by existing IAT scripts taken from the task library include Greenwald's improved scoring algorithm?
I have adapted both the Career-Gender IAT and also the Race (faces) IAT for my research. I have both raw data and summary data. The summary data includes the D score for each IAT. Is this computed as recommended or would I need to use the raw data and compute the D scores myself using the IAT SPSS syntax to ensure things such as response times below 300ms are excluded?
Any advice is greatly welcomed.
Thanks in advance.
Jo
