Imagine you're trying to detect a lie using a simple reaction time test. Scientists have been experimenting with adding special "filler" items to make these tests more effective. These fillers are meant to grab your attention and make you think harder. But do they really work? Olson and team found that these fillers might not make a big difference after all. They thought that making you think too much could actually make the test less effective.

        Lukács and crew came up with a new type of filler, called "importance-related" fillers. They thought these would be easier to understand and follow. A study tried to see if these new fillers would boost the tests even more. They tested three different ways to do the test: the enhanced concealed information test (E-CIT), a simpler version of the E-CIT, and the classic three-stimulus protocol (3SP-CIT).

        The results showed that the E-CIT did make people react slower, which is a good sign for the test. But, the special fillers didn't make the P300 part of the test any better. Even the simpler version of the test didn't show any big improvements. This means that even when you try to make the test easier, the fillers still didn't help the P300 part.

        So, what does this all mean? It seems like adding special fillers to lie detection tests might not be as helpful as scientists thought. Maybe there's something else we need to figure out to make these tests even better.
