The term ESP has been used been used by different people to mean different things, which is why I try to avoid it. Instead, when talking to a general audience, I prefer to use the term sixth sense.

As addressed in a previous comment, the term "sixth sense" is usually taken to mean something along the lines of "A power of perception seemingly independent of the five sense" (American Heritage Dictionary) or "a power of perception beyond the five sense" (Webster's College Dictionary).

In our study, we showed that observers are sometimes able to reliably sense changes that they cannot identify, changes that they (erroneous) believe that they did not see. So from their perspective, the experience was similar to that of a sixth sense, in that they could sense information that they believed that they could not see. We were able to show how this processed worked and debunk the claim that this was due a ability such as the sixth sense. The point is that people can sometimes get the strong impression that they can sense changes that they cannot see. What we showed was that while this sensing ability is indeed real, it has nothing to do with a sixth sense, and can be explained in terms of known visual processes
