This study investigates the use, form and function of humor for children ag
ed 12-16 years in two different schools including 47 participants through i
nterviews and 112 participants in a questionnaire. The assumption is made,
that developmental changes in form and function of humor for children aged
12-13 years may be influenced by their actual environmental settings and th
eir actual tasks. Data from 12-16 year old children from two schools (schoo
l 1, in the countryside with grade 1 to 7 and school 2 in an town area with
grade 1 to 100) is analyzed to see whether adult humor appears at an earli
er stage in school 1. Finally, the study considers the importance of childr
en's sense of humor in problem solving and social interaction during the pe
riod 12-16 years.
