Isen (1984) and Berkowitz (1987) noted the strong link between positiv
e moods and positive thinking. Isen proposed that the well-established
relation between positive moods and increased helping or compliance i
s attributable to the mediating effects of positive thinking. In the c
urrent study, the effect of interest-a type of positive thinking-on co
mpliance was examined. Because of the strong link between positive moo
ds and positive thinking, it was expected that inducing interest would
increase compliance. College students sitting alone in a university l
ibrary were approached and asked to complete an interesting task, an u
ninteresting task, or were not asked to do an initial task. All studen
ts were then asked to answer questions from a sociology survey. Studen
ts in the interesting task condition were willing to answer more quest
ions than students in the other two conditions, in which compliance ra
tes were equal. A second experiment was conducted to determine whether
the task used in Experiment 1 increased compliance because it increas
ed interest or because it induced guilt or lowered self-esteem (the ta
sk was a perceptual trick that most students got wrong even though it
appeared very easy). Results showed that the interesting task created
not only more interest, but also more guilt than the uninteresting tas
k. Both interest and guilt contributed independently to compliance. To
gether, the two experiments showed that interest, like positive affect
, can increase compliance.
