single target IAT (another poor fool who is confused about d scores)

Group: Forum Members Posts: 9, Visits: 1	Hi, I have browsed the forums in great depth looking for the knowledge I seek regarding d scores, so please rest assured that I made sure this question wasn't answered elsewhere before I posted (I think)... I am running an edited version of the single target IAT template posted on the website, with the only major change to the script being a shift from 8 to 4 items. I am a total IAT newbie - though after browsing these forum posts I now understand what the D score is, how is computed etc. My understanding is that the column labeled "expressions.d" should be reporting a total D score for each participant - I can't find it! I see d scores for each target/attribute, but no big daddy grand master D (though it is reported to each participant on the screen after they finish the task). could you please help me figure out where this D is being recorded in the .dat file? here is my script for your perusal... thanks, dan Attachments SingleTargetIAT_Human Giving.exp (748 views, 14.00 KB)

Group: Administrators Posts: 12K, Visits: 98K	+x Lisa Z. - Monday, December 18, 2017 Hello, we are also running an edited version of the single target IAT template posted on the website. The only major change to the script is, that we use only one sequence of blocks: there are two blocks in the original script, namely "latdiffa:difference in mean latencies of the first blocks (first compatible and first incompatible block)" and "latdiffb:difference in mean latencies of the second blocks (second compatible and second incompatible block)". Now two questions: first, can we still use the SPSS syntax provided on the website? Second, which d-scores are calculated by Inquisit, is this the D-600? Thank you in advance! Lisa #1: I'm not sure what you mean by "we use only one sequence of blocks". If this is supposed to mean that you run _fewer_ blocks, you may have to adjust the SPSS syntax. If this is supposed to mean you are only administering one _block order_ (e.g. compatible first only instead of compatible first AND incompatible first counterbalanced between subjects), you don't have to modify the syntax. #2: The D-scores calculated by Inquisit are "D biep", i.e. "D with built-in error penalty" as recommended by Greenwald et al. 2003.
