Humor is frequently associated with creativity but its role in other f
orms of problem solving has received less attention. In this experimen
t, humor was examined as a possible primer for enhanced performance in
an imaginal and in a verbal task. Jokes and simple sentences of high
or low imagery were presented prior to participants' attempts to solve
either mental rotation of figures or verbal analogies. The effect of
imagery, as manipulated here, was not significant. Humor, however, spe
eded mental rotation and slowed performance on analogies or men, where
as women's solution times were relatively unaffected Greater hemispher
ic lateralization among men was considered as a possible explanation f
or this pattern of results.
