Scoring algorithm

[TiagoDevezas]

Hi,

does this use the original IAT scoring algorithm or the improved version described in Greenwald, Nosek & Banaji (2003)?

Thank you.

I'd like to know this too! I've got my IAT collecting data right now for my dissertation, but will be to data analysis soon...

It seems in the R-script that this is the old algorithm, but I'm not entirely sure. I emailed the developer to see if this is true. Has anyone else figured this out?

It applies the original scoring algorithm as described by Greenwald et al. 1998. If I have time I might try to implement the more sophisticated algorithm.

Here is an updated R script that uses the modified algorithm. Basically just 'formats' the output into a dataframe that can be run through the package: IAT. https://cran.r-project.org/web/packages/IAT/IAT.pdf

I'm sorry that the code is a bit messy. Feel free to email me if you have any questions: anton.gollwitzer@gmail.com
