How seductive details do their damage: A theory of cognitive interest in science learning.

Abstract
In 4 experiments, students who read expository passages with seductive details (i.e., interesting but irrelevant adjuncts) recalled significantly fewer main ideas and generated significantly fewer problem-solving transfer solutions than those who read passages without seductive details. In Experiments 1, 2, and 3, revising the passage to include either highlighting of the main ideas, a statement of learning objectives, or signaling, respectively, did not reduce the seductive details effect. In Experiment 4, presenting the seductive details at the beginning of the passage exacerbated the seductive details effect, whereas presenting the seductive details at die end of the passage reduced the seductive details effect. The results suggest that seductive details interfere with learning by priming inappropriate schemas around which readers organize the material, rather than by distracting the reader or by disrupting the coherence of the passage.
