jsPsych IAT D-Score calculation

[rsssss12]

Hello,

I have a question about the IAT example (https://github.com/jspsych/jsPsych/blob/main/examples/jspsych-iat.html). In line 478 it is stated from which paper the D-score calculation is taken from (http://faculty.washington.edu/agg/pdf/GB&N.JPSP.2003.pdf). In the paper, table 4 compares the conventional algorithm to the improved algorithm. It seems like the IAT example tries to follow the improved algorithm for the D-score calculation, right? It seems then that the IAT example is falsely implemented, because the improved algorithm calculates the D-score also from block 6 and block 3. Line 370 and line 189 are proof that in the example both blocks are seen only as a practice block. Am I just wrong or is the calculation falsely implemented?

Yours Sincerely
