Change Feedback Responses

[Alexis Collins]

Hi all, 

I'm unsure how to change the default responses for the feedback in the IAT when NOT using Qualtrics (i.e., what file to put the code in and what code to use, scorer?)

Thanks

Hi,

We created the IAT extension for Project Implicit's website. In that website, for educational purposes, at the end of most of the studies, we tell participants in which pairing condition they were faster. In experiments in other settings (e.g., in the lab), I usually don’t do that. When we present the participant’s own results in Project Implicit’s website, we provide much context to the participant, to make sure they don’t think that the result is more than an educational tool. The IAT (like all the other “implicit measures”) is not accurate enough to provide a reliable estimate of attitudes for each participant. Therefore, I strongly recommend not to present feedback to your participants.

If you still need to show feedback and you want to change the feedback wording, you should add the relevant arguments to your call to the iat extension. Let’s use the feedback example study mentioned in this section in the blog post about how to create the free standalone web IAT. In that example, the file that uses the iat extension is raceiat.js. It does not include the arguments to change the feedback messages. To see all the arguments that the IAT extension can accept, we read the beginning of the IAT extension script. The arguments are listed under the “var iatObj” line. Scrolling down, you’ll eventually see the relevant arguments (with comments explaining their format):

    //The default feedback messages for each cutoff -
    //attribute1, and attribute2 will be replaced with the name of attribute1 and attribute2.
    //categoryA is the name of the category that is found to be associated with attribute1,
    //and categoryB is the name of the category that is found to be associated with attribute2.
    fb_strong_Att1WithCatA_Att2WithCatB : "You were much faster at sorting 'categoryA' with 'attribute1' and 'categoryB' with 'attribute2' than 'categoryB' with 'attribute1' and 'categoryA' with 'attribute2'",   
    fb_moderate_Att1WithCatA_Att2WithCatB : "You were moderately faster at sorting 'categoryA' with 'attribute1' and 'categoryB' with 'attribute2' than 'categoryB' with 'attribute1' and 'categoryA' with 'attribute2'",
    fb_slight_Att1WithCatA_Att2WithCatB : "You were slightly faster at sorting 'categoryA' with 'attribute1' and 'categoryB' with 'attribute2' than 'categoryB' with 'attribute1' and 'categoryA' with 'attribute2'",
    fb_equal_CatAvsCatB : "You were about equally fast at sorting 'categoryA' with 'attribute1' and 'categoryB' with 'attribute2' and at sorting 'categoryB' with 'attribute1' and 'categoryA' with 'attribute2'.",

You can copy those four arguments to your own script (the one that calls the iat extension), and change the text.

I hope that helps,
Yoav
