identify correct answer after random pairing

[juliaff]

Hi!

(see attached my reduced input-file)

In the presentation phase (here just trial 2 and 3) I combine among other things stim4 (a dichotomous additional info = E or G) with stim5 (a sentence about a person). I have 6 lists of different sentences used as stim5 (here just v_con_j.txt), just to make clear that it is not only this one.
The combination of the sentences in these lists as stim5 with the dichotomous info E or G should be randomly done by directRT. Therefor I use $ and WGR.

Later I want my participants to indicate for each sentence the dichotomous info, i.e. if it was E or G. The sentences should be presented randomly, then the participant should answer. Because I have a jump mid-trial in these recognition-task it doesn’t seem too easy (here trial 5 and 6) ..

Here is my problem: How do I identify, if the answer of the participant is right or wrong?

I would be sooo happy if you have any suggestions!
