data analysis with output

[gdfscres]

hi there!
thank you for creating an open-source version of the IAT. we have used the older version of the program that was located on sourceforge and have transformed the output into an excel file and an spss file, with one participant per line. we know what each of the variables is (block, round, etc.) but we're not sure how to use this data to obtain anything other than a simple IAT score comparing reaction times.

for commercial programs, we typically use SPSS syntax that comes with the program in order to analyze the data. is there a similar algorithm available for this program?

thank you!

Yes. It is located in the root directory of the project. It is called IATanalysis.R. This a script coded by @winteram for analyzing the collected data. In order to use it you would need to install the Open Source statistical package known as R. Unfortunately it has a steep learning curve but you can use the code as is.

Cheers!

Has anyone updated the code in accordance with the improved scoring algorithm outlined in Greenwald, Nosek, and Banjai (2003) (located here: http://faculty.washington.edu/agg/pdf/GB&N.JPSP.2003.pdf).
