To explain an intuitive rationale behind linking humor type preference to post adulthood age.
Humans are considered mature and accountable usually at age 18 yet their behavior keeps developing afterwards. Post adulthood age related behavioral development cannot be attributed to cognition otherwise it would be a legal issue, e.g. a systematic factor in determining the guilt or innocence beyond adulthood. Behavioral development has to be attributed to motivation.
Humans are considered legally responsible when they reach the age of adulthood, implicitly achieving cognitive development sufficient to tell right from wrong. Behavioral changes beyond adulthood could not be considered cognitive otherwise each age group would have a different set of laws, age related changes beyond adulthood had to be strictly motivational in the eyes of the law. Artificial Psychology seeks to model the systematic change in motivation over adulthood.
