Maasai - Age-sets. Introduction. The basic Maasai political and social structure is their rigid system of age-sets (or age grades; strictly-speaking, an age-grade is a stage within the age-set). These apply primarily to men; women automatically become members of the age-set of their husbands. Under this system, groups of the same age (give or take five years or so) are initiated into adult life during the same period. The age-set thus formed is a permanent grouping, and lasts throughout the life of its members.
Originally, the differences between mental age and chronological age were used to compute the intelligence quotient, or IQ. mental age Ã· Physical age Ã 100 = IQ. No matter what the child's chronological age, if the mental age is the same as the chronological age, then the IQ will equal 100. Modern intelligence tests, including the current Stanford-Binet test, no longer compute scores using the IQ formula.
