Brief IAT and traditional IAT in the same script?

Hello,

I need to run a Brief IAT (BIAT) and traditional IAT (IAT) over the course of my experiment. I also need to randomize the order of the BIAT and IAT.

I was reading about the batch and include commands here (http://www.millisecond.com/support/docs/v4/html/howto/multiplescripts.htm), but it looks like the batch command cannot randomize the order, and the include command may not be compatible with BIAT. Hopefully I am wrong about that, though; any help you can give is appreciated.

Thank you!

The simple approach is to use <batch> elements (they can randomize, etc. order via /subjects and /groupassignment attributes just like an <expt> does):

<batch>
/ file = "RegularIAT.iqx"
/ file = "BriefIAT.iqx"
/ subjects = (1 of 2)
/ groupassignment = random
</batch>

<batch>
/ file = "BriefIAT.iqx"
/ file = "RegularIAT.iqx"
/ subjects = (2 of 2)
/ groupassignment = random
</batch>

Regarding <include>: The <include> element is not incompatible with anything -- all <include> does is effectively paste ("include") the contents of one file in another file. Using it to combine a regular IAT and a Brief IAT by and large works the same way as detailed in the documentation topic you mentioned.
