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

You'll find all of this covered in detail at http://www.millisecond.com/forums/Topic3444.aspx.

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