This defense of the authors' previous report states that there is a large sex difference in mathematical reasoning ability among intellectually talented preadolescents. The authors concluded differential course taking could not account for observed sex differences among intellectually gifted students, although this may affect average ability…

Two experiments compared the working memory performance of 77 highly gifted seventh and eighth graders (13 and 14 Years ole) with verbal or mathematical precocity, or both. Different types of intellectual talent correlate with different working memory characteristics and differences in how digit and word stimuli are represented in memory. (SLD)

Study 1 examined construct validity of the Strong Interest Inventory and the Study of Values for 695 intellectually talented 13-year-olds. Study 2 consisted of a generalization probe to 695 graduate students. Analysis manifested an impressive degree of adolescence-to-adult cross-validation. Assessment and counseling with gifted students is…

Data from a longitudinal survey of mathematically precocious 13-year olds (n=1,247) were used to test 5 factors (quality and quantity of instruction, home environment, motivation, and ability) for their ability to predict educational achievement and educational and career aspirations. Students were followed until age 23. (SM)

The predictive validity of the mathematics subtest of the Scholastic Aptitude Test (SAT-M) was investigated for 1,996 mathematically gifted (top 1 percent) seventh and eighth graders through academic achievements assessed over 10 years. The SAT-M appears to have predictive validity for differentiating highly able seventh and eighth graders. (SLD)

Two studies conducted with 244 academically gifted seventh graders and 1,996 high school students indicate that specific content knowledge taught during a short time does not increase Scholastic Aptitude Test (SAT) scores, but that educational experience over 5 years does relate to development of abilities measured by the SAT.
