Memory for humorous and nonhumorous versions of sentences was compared
. Humorous sentences were better remembered than the nonhumorous sente
nces on both free- and cued-recall tests and on measures of sentence r
ecall and word recall. These effects persisted when subjects were warn
ed that they were about to read a humorous sentence but were attenuate
d in incidental learning and limited to within-subjects manipulations.
In incidental learning, recall was also scored as a function of subje
ctive ratings of humor. Subjective humor affected memory in both withi
n- and between-subjects designs. Attention, arousal, rehearsal, retrie
val, and surprise explanations were explored. Results suggest that hum
orous material receives both increased attention and rehearsal relativ
e to nonhumorous material.
