For demonstration's sake, take a situation in which you want to reveal whether a person is aware of a certain date. For example, someone is suspected to be concealing the knowledge of an upcoming terrorist attack on May 9. In this case, five different, additional dates should be chosen randomly. For example, June 14, December 5, August 25, February 12, and March 29. From among these, one should be chosen randomly as target, for example, August 25. These should be filled in accordingly on the starting page. Probe: MAY 09, Target: AUG 25, and the remaining four dates as Irrelevants. (Note that only the first three letters of the month are displayed, so that the length of the item texts would be the same. Shorter text may result in faster responses, which would introduce a bias.) The Experiment title may be "detect_relevant_date". The Subject ID could be "suspect_01".
All these data can be filled in automatically for a demonstration using the following button:
If you would like to do a pilot test to see that the method truly detects a relevant detail, one good way is to enter your own personal name (e.g. family name) and, as target and irrelevants, enter other, randomly chosen names. If you then complete the test in the enhanced version with, say, two blocks, it is very likely that you will be detected. (Personal names are typically highly personally relevant, and thus appear highly salient in the task.) For a control test, to show a no effect (simulating innocence), you may enter random names for all items, including probe, target, and irrelevants. Note that, in this case, the person tested should not know which item is the probe item! The mere knowledge of the relevance of this item (as the probe to be tested) can cause different responding. Thus, first the start page should be completed and the test started (by clicking the START TEST button) without the examinee seeing these details.
For the detailed mechanism of the task, as well as for how to use it (and test it programmatically), see the documentation.
