Hi,

I am trying to write a study based on an adaptation of the Age IAT from the test library (http://www.millisecond.com/download/library/AgeIAT/). What I am trying to run is based on a 2 (Good_A vs. Good_B) X 2 (Young_A vs. Young_B) between-subject design. So all participants will still see same words related to "Bad" and same pictures related to "Old". But they will be randomly assigned to see just one of the four conditions:
1)  words related to "Good_A" and pictures related to "Young_A";
2)  words related to "Good_A" and pictures related to "Young_B";
3)  words related to "Good_B" and pictures related to "Young_A";
4)  words related to "Good_B" and pictures related to "Young_B".

I wonder how I may revise the coding of the Age IAT script, to achieve such a design.

Any advice would be greatly appreciated.
