Dear all,I have been trying to program my IAT on Qualtrics using prof. Bar-Anan's code available here https://github.com/baranan/minno-tasks/blob/master/IAT/qualtrics/quiat10.jsand then using his R codes here https://github.com/baranan/minno-tasks/blob/master/IAT/qualtrics/minno.qualtrics.iat.process.rmdI have three questions:1) Is there a reason why the cleanIAT function of the IAT package calculates a d-score which has an opposite sign with respect to the one I get directly from Qualtrics using the MinnoJS code?
2) Moreover, I wanted to ask whether the IAT d-score has a different interpretation if category1 is on the left first or on the right first (and hence if i should take into account the initial position of category1 when calculating the d-score with the cleanIAT function, for example by dividing the sample into two groups and get d-scores for the two groups). I assume not, but I am not sure.
3) I am using a gender-caree IAT, with Category1=Career, Category2=Family, Attribute1=Male, Attribute2=Female.
Am I understanding correctly that, on the basis of prof. Bar-Anan's code, if we display as feedback'Your responses suggested a strong automatic preference for Family over Career.'we are meaning that the respondent is implicitly associating the couples Career/Male and Family/Female?

I have used your R script to calculate D scores for an IAT that I ran with Qualtrics using the MinnoJS extension. The R script is working for me, but I have a few questions.
https://github.com/baranan/minno-tasks/blob/master/IAT/qualtrics/minno.qualtrics.iat.process.rmd
My questions are:
Please let me know if anything is not clear.
Thank you,
Julie
My questions are:
- Using your R script, do resulting positive D scores always indicate a stronger association between the category-attribute pairs in the compatible block than the incompatible block?
- Will the script automatically exclude people with problematic rt or accuracy performance, or does something need to be edited in order for an exclusion to happen? (No one is currently excluded from my data, n=30).
- What is the b0rd variable and how is it involved in calculating D scores?
- Is it correct that I can include data from participants who have completed the incompatible block first and participants who have completed the compatible block first in the same csv file that I use with the R Script, and that positive D scores would indicate the same thing for both participant groups? That is, in terms of calculating D scores, are differences in block order between participants corrected by using "blockName"?
