Mathematical giftedness (MG) is an intriguing phenomenon, the nature of which has yet to be sufficiently explored. This study goes a step further in understanding how MG is related to expertise in mathematics (EM) and general giftedness (G). Cognitive testing was conducted among 197 high school students with different levels of G and of EM. Based…

In order to achieve the present study's goal--to understand better the phenomenon of mathematical giftedness--we performed a multidimensional examination of the mental processing in students who exhibited mathematical expertise (EM) at the secondary school level. The study included participants from the three groups: students who excelled in…

Little empirical data are available concerning the cognitive abilities of gifted individuals in general and especially those who excel in mathematics. We examined visual processing abilities distinguishing between general giftedness (G) and excellence in mathematics (EM). The research population consisted of 190 students from four groups of 10th-…

Background: Both ability (measured by power tests) and non-ability (measured by preference tests) individual difference measures predict academic school outcomes. These include fluid as well as crystalized intelligence, personality traits, and learning styles. This paper examines the incremental validity of five psychometric tests and the sex and…

The purpose of this research was to study the correlation between socioeconomic status and intelligence. The Project Talent Data Bank was used in the study. The measures of privilege/deprivation developed show some degree of differential abilities and the measures of intellectual privilege are almost cogeneric measures of general intelligence.…

A study conducted in four Wisconsin secondary schools attempted to measure student abilities in evaluating verbal argument and to determine the grade level at which verbal argument concepts and skills should be appropriately taught. Seven tests, known as the Wisconsin Tests of Testimony and Reasoning Assessment (WISTTRA), were administered to 3000…
