Hello,

I hope this message finds you well.

I am having difficulty counterbalancing the presentation of two IATs that I will be using. Specifically, I would like for some participants to receive the IAT1 first and then IAT2 and for others to receive IAT2 first and then IAT1. Also, after they answer both IATs, I want them to answer a series of questionnaires.

My current script/syntax is the following:

<batch>
/ file = "JP demographicsurvey.iqx"
/ file = "JP Iat1.iqx"
/file = "JP-Iat2.iqx"
/ file = "9 Script.iqx"
/ file = "7 Script.iqx"
/ file = "ISS script.iqx"
/ file = "SEE.iqx"
/ file = "IScale.iqx"
/ file = "Personal Experiences.iqx"
<batch>

Thank you!
Juan

You need to define two <batch> elements -- one running IAT #1 first, one running IAT #2 first -- and then assign participants (e.g. randomly) to one of the two <batch> elements:

<batch>
/ subjects = (1 of 2)
/ groupassignment = random
...
/ file = "JP Iat1.iqx"
/ file = "JP-Iat2.iqx"
...
</batch>

<batch>
/ subjects = (2 of 2)
/ groupassignment = random
...
/ file = "JP-Iat2.iqx"
/ file = "JP Iat1.iqx"
...
</batch>
