IAT randomization

[jarvis24]

Sanspeur--thank you for the kind words about our software--of course, feel free to post a quick review here: http://www.empirisoft.com/support/showthread.php?t=46

Regarding the IAT design, we tried to replicate the classic designs of yesteryear as closely as possible. Being out of social psych for a while now (and into software/hardware) I wouldn't want to advise you on this. I would seek opinions from a source such as the SPSP list serve. Let me know if you'd like details on how to do that. In general though, randomization with replacement (or in our lingo "true") is rarely as useful in a practical way as it is in a theoretical way. Randomization without replacement simply gives you the ability to ensure equal n's--but that can trump the niceties of "true" randomization. But again, I'd consult "true" IAT researchers or the social psychology world in general for design questions like this. I can say though that Tony Greenwald gave our sample IAT a test run many years back and gave it thumbs up. Hope that helps!
