This article examines two related issues: how variation in the level o
f self-reference in which people engage affects their persuasion and w
hat factors may moderate self-reference effects. Respondents viewed ad
s that varied on two dimensions intended to influence the use of self-
reference, namely, the wording of the ad copy and the perspective from
which the ad photo was shot. Results indicated that an initial (moder
ate) increase in self-referencing enhanced persuasion, while a further
(extreme) increase undermined persuasion. These effects emerged, howe
ver, only when subjects were highly motivated to attend to the ad. Whe
n ad recipients' motivation was low, self-referencing had no effect.
