I am designing a memory experiment with a deceptive critical trial, wherein an item is swapped without the participant's knowledge.
What is the best way to determine if the participant has noticed the swap, without actually informing them of it?
I.e., asking the participant 'did you notice the swap we just made' is rather informative about the possibility of a swap :)
- a statement at the beginning asking them to mention any inconsistencies noticed
- a direct question directly after the swap, and
- a direct question at the end of the experiment
I think the first and second are likely to induce noticing (the latter by comparison to earlier memories that otherwise would not have been performed) and the last to potentially under-report.
