Dear Dave,

I am using the letter-memory test for about 2 months now but it appeared that 'recallDuration', 'values.correct', 'values.countCorrectLetters' and 'list.correctLetters.itemcount' are only being saved for the practice trials (the first 3 trials) and not for the test trials (the following 12 trials).

I assume that the fault should be in the below part of the script.
Can you please check?

We would like for the test trials to only record data, not give any feedback after each trial.

I look forward to hearing from you.

Best regards,

Bob Ramakers

Note: trial.recall_end
* presents feedback
* evaluates the accuracy of the response (uses the first three letters entered by participant - any additional letters are ignored)
* order of letters is not important
* adds an ITI as the posttrialpause

I'm not sure what the relevance of the code snippets you posted is. There is no "recall_letter2" trial in the original script, so I must assume you modified the script and probably broke it. I cannot assess that on the basis of incomplete excerpts. Note that values.countCorrectLetters and values.correct are updated in <trial recall_end> in the original. If you don't run that <trial> during the test block, this will obviously not happen.
