<p>As a participant completes the IAT, Inquisit keeps a running trial-by-trial tally of d, which is the standard metric used to interpret IAT results. The final d score for a given participant thus appears on the last row of data for that participant. Inquisit reports 3 d scores, which appear in the last 3 columns labeled "expressions.da", "expressions.db", and "expression.d".</p>
<p>Expressions.da is the d score from just the practice (i.e., first) blocks for both pairings. </p>
<p>Expressions.db is the d score from just the test (i.e. second) blocks for both pairings. </p>
<p>Expressions.d is the d score for both practice and test blocks. This is the score that is typically reported as the measure of association. </p>
<p>D scores can be positive or negative. A positive score indicates an association of targetA with attributeA and targetB with attributeB. A negative score indicates an association of targetA with attributeB and targetB with attributeA. Translating the score into a preference or attitude thus depends on how you have assigned your real world categories to these 4 groups. You can determine the mappings by looking at the topmost section of your IAT script, where you'll see the <item> definitions for each category.</p>
<p>For example, let's say you are studying implicit attitudes towards neckties vs ascots, where neckties are targetA, ascots are targetB, pleasant words are attributeA, and unpleasant words are attributeB. A positive d score would indicate the participant is more of a necktie sort of person. A negative score would indicate an affinity for the classic and elegant ascot look. A score of zero would indicate no preference.</p>
<p>Inquisit also records all of the raw responses and response latencies for every trial so that you have the option of running post hoc analyses on the data (e.g., to experiment with different methods of handling outliers). We offer an SPSS command script that provides a good starting point for this, which you can download from our IAT page:</p>
<p>http://www.millisecond.com/download/samples/v3/IAT/default.aspx</p>
<p>If you run the script as is, you'll get exactly the same d scores as those described above, but the script can be easily edited to do custom analyses. </p>

You wrote that the only difference between the calculation of Inquisit and the 'improved scoring algorithm' would be that subjects below 300ms on 10+% of the trials are not automatically discarded. I'm writing my bachelor thesis at the Moment and I used only the automatic generated d-scores for my calculations. now I'm asking myself if it's still ok to write, that the computation of IAT scores is based on the scoring algorithm provided by Greenwald et al. (2003) and how I could establish the fact that subjects below 300ms on 10+% of the trials were not automatically discarded? Even though I have the raw data collected it would cost me months to transfer them into a SPSS data set and compute them with the provided syntax for several reasons. So is there a convincing explanation which i could use for my argumentation why I haven't discarded subjects below 300ms? Next time i would handle it different because now I know much more about IATs and the functions of Inquisit. But for this time it would be so helpful if I could to it that way.
