How "RIGID" Is THE "AUTHORITARIAN?" 137 mental testing materials, yet middle-status 5s were clearly superior to lower-status 5s. Generalization from these findings is limited by the method of sampling (selection) used in obtaining 5s, as well as by the fact that only one intelligence test was represented.The study does seem, incidentally, to support the belief that the ability to engage in abstract behavior increases with age and education through childhood and early adolescence. It is possible, however, that this finding resulted from successively more abstract content in the primary, elementary, and intermediate forms of the intelligence test used at the third, sixth, and ninth age-grades respectively to equate the two status groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
