Hawthorne Effects

refer to distortions and possibly non-sustaining effects of a treatment just because its newness captures more of an individual's attentiveness. In double blind studies of the impact of technologies upon learning, Hawthorne effects are particularly troublesome. Students are more apt to be more attentive to newer technologies simply because they are "new" curiosities. Positive results on learning impacts may not be sustaining, however, after the novelty and curiosity factors decline with repeated use of the technology over time.
