Surprise has been recognized as a key process in humor. Past studies have seldom tested elements that could increase the surprise in humor advertising, subsequently increasing perceived humor and positive ad outcomes. The purpose of this paper was to test the effects of priming a lower arousal baseline before humor ad exposure. It proposed that this would generate greater humor ad surprise because of contrast effects, leading to greater perceived humor and positive ad effects.
Three experiments tested the effects of arousal and valence of primes on humor ads. Attention, perceived humor and ad effectiveness of the humor ads were measured.
Evidence of lower (vs higher) arousal primes leading to greater humor ad evaluations was found across three experiments. Felt arousal of the ad mediated the relationship between the prime conditions and perceived humor.
No study has focused on context effects of the unique process of humor ads. This study advanced the arousal theory of incongruity-resolution humor and further emphasized the role of surprise. The findings implicate that the surroundings of the humor ad could increase its effectiveness.
