The social facilitation of humor appreciation is a widely held belief but narrowly researched concept. This study was designed to show the involvement of spatial density as well as social density in the appreciation of humor. Male and female adolescents representing ages 11 to 18 years
participated under conditions of high and low spatial density. High spatial density was found to significantly diminish appreciation of three humor types. Significant sex and age differences in reactivity to spatial density were found. Results expand current knowledge of the effects of density
on the appreciation of humor and suggest the capability of spatial density to inhibit positive affect.
