Hello!

I have a fair bit of Inquisit experience, and have been scouring the forums but can't quite find an answer to this question, and haven't yet figured out how to do it myself.

The question is:
a) how do i keep track of all stimuli that were selected from a list - StimulusListA - to be presented in Task 1 (for simplicity let's say Task 1 is all in  a block called "categorization_task_block")
SO THAT
b) I can make sure those previously used stimuli are NOT selected from the SAME LIST on a subsequent task, block "recall_task_block".

Basically, I am asking participants in the categorization_task_block to simply categorize stimuli that are presented one at a time. We have working code for this, and I know I can store the names of the stimuli presented, which were pulled randomly from a large list.

THEN, in the recall_task_block, I want participants to do a recall test. Critically, half of the stimuli used for this recall_task_block will be stimuli they were presented during the categorization task, and half will be stimuli THEY HAVEN'T SEEN, but were also in StimulusListA.
I can't quite figure out how to make sure that the recall_task_block checks the list of previously presented stimuli from the categorization_task_block?

Thank you! I will post some example code in a moment.
