Alcohol Dot Probe - How to import raw data in workable SPSS format

An undergraduate of mine will do work on alcohol identity and alcohol attention using the Alcohol Dot Probe (ADP). We want to use this ADP using Inquisit 4.0. The data that we have collected so far gives us the raw data file - however, this raw data file is structured in such a way that each participant has 90 rows of SPSS data.

From earlier work using IAT, I know that there are (were?) scripts available (such as this one http://www.millisecond.com/download/library/BriefIAT/) that allow a SPSS syntax script to restructure this raw data in workable SPSS format.

Is something also available for the ADP that we are going to use? I would love to know how to restructure my data into analyzable format.

Thanks!

There is no SPSS syntax available to restructure raw data files stemming from the alcohol dot probe. You'd have to write those yourself. The process is always the same, and the following sources provide useful introductions to processing, restructuring and readying raw data for further analysis:

Beyond that, note that the ADP script not only produces "long format" raw data files, but also summary data files containing a single line of summary statistics per subject. The various variables recorded are detailed in the script's comments.

Thought as much :) I was probably spoiled with the IAT scripts Inquisit has available, thanks Dave!
