Changes in Intelligence from 1960 to 1995 in Relation to Cohort, Gender, and Socioeconomic Background.
Svensson, Allan; And Others
As part of a continuing evaluation of the Swedish school system, changes in intelligence test scores from 1960 to 1995 were studied in relation to cohort, gender, and socioeconomic background. Changes in verbal, spatial, and reasoning ability were studied by comparing results on identical tests given to representative samples of Swedish 13-year-olds on six occasions from 1961 to 1995. The first data collection involved about 12,000 students, 90% of whom were in sixth grade in 1961. In 1966 approximately 10,500 students born in 1953 were studied. The 1980 data collection, the third overall, used approximately 9,000 students, mostly born in 1967. The fourth, fifth, and sixth data samples were drawn in about the same way as the third sample, using mostly students born in 1972, 1977, and 1982. Verbal test scores tended to rise until 1980, after which there was a stronger tendency in the opposite direction. However, behind the decrease are changes in the proportion of older Swedish and foreign words, so that it is really only possible to say that students' vocabularies are different than they were 35 years earlier. Results in the spatial test rose considerably up to 1995 and girls' results more nearly approached boys' over the period. These changes may reflect the introduction of preschool and comprehensive school education in Sweden. In the reasoning test, increases were found for the first two decades, again perhaps reflecting changes in the educational system. An appendix contains five tables of test results. (Contains 3 figures, 16 tables, and 16 references.) (SLD)
