Lee-Ann,
In fact, in one version of the researcher’s experiment, they warned students that certain seductive details would appear in the text but that the students should ignore them. This seems a little bit to me like saying, “Don’t think of an elephant.” The results were as you would expect: telling students to ignore the seductive details in the text only focused them on them.

Still, your question seems to me to work in two other ways:
1. One, which I mentioned above, is whether seductive details can be intertwined with relevant content to enhance recall of relevant content.

2. The other, perhaps more relevant for Writing Studies, would be to draw readers’ attention to the seductive details as part of a (literacy?) exercise, to get the readers to think about how the authors are attempting to capture and hold their attention.
