The 9th International Conference on Educational Data Mining (EDM 2016) is held under the auspices of the International Educational Data Mining Society at the Sheraton Raleigh Hotel, in downtown Raleigh, North Carolina, in the USA. The conference, held June 29-July 2, 2016, follows the eight previous editions (Madrid 2015, London 2014, Memphis…

Raven's Progressive Matrices is a frequently used intelligence test, and it has been suggested that the major determinant of difficulty for each item is its numbers of elements and rules, and its rule complexity. The current study investigated another potential source of difficulty--element salience--items are harder where their elements are…

The controversy over the causes of intelligence--genetic or environmental--is reviewed. More specifically, the subject of the consistently lower intelligence scores for blacks is analyzed. Much attention is devoted to Jensen and his monograph published in the "Harvard Educational Review," entitled "How much can we boost IQ and scholastic…

In keeping with a model of intelligence that identifies at least 12 intelligence "talents," formal and informal intelligence or talent assessments have been developed. This paper presents some of these informal instruments that can be used to assess convergent and divergent forms of intelligence. These nontraditional instruments have been designed…

Supports, generally, results of Walker and Spence study of 1964. Also demonstrates that subjects who are affected negatively by experimental procedure are likely to perform poorly on a variety of tasks. (Author/CJ)

Traditional psychological testing programs and the role of the teacher in providing individualized instruction are typical of the problems and prospects for integrating our knowledge of how brain damage influences intellectual abilities with common problems in educational practice. (CH)

Results for 3,340 participants taking a battery of cognitive tests and an analysis of the Spanish standardization of the Wechsler Adult Intelligence Scale-III support the differentiation of intelligence across the range of ability, with WAIS-III results more supportive of the differentiation theory. (SLD)

Provides tables of critical values for determining statistically significant discrepancies between Wechsler Verbal/Performance IQ and Wechsler Individual Achievement Test subtests and composite scores based on predicted-achievement method. Recommends that tables be used when statistically significant and diagnostically meaningful Verbal…

Studied sex differences in general intelligence in 10,475 adults taking cognitive test batteries. Results suggest a negligible difference in general intelligence, a finding consistent with findings from quite different test batteries and subject samples. (SLD)

Given well-known difficulties in justifying the Galtonian conception of intelligence as innate general intellectual capacity, a historical explanation is required of why this problematic notion became so prominent in Britain and in the USA in the late nineteenth and twentieth centuries. Parallels are drawn between it and various features of the…

Because figural reasoning tasks are often assumed to indicate fluid intelligence (gf), we investigated which aspect of figural reasoning tasks make that they tend to mark gf-the figural content itself or the high degree of abstraction in these tasks. To this end, the assessment of figural reasoning abilities by means of concrete figural task…

The threshold hypothesis regarding creativity and intelligence suggests that these two constructs are positively correlated except at the higher end of the IQ distribution, where they are unrelated. Much of the support for this hypothesis comes from comparisons of correlations within average and high-IQ groups. However, a common methodological…

First, I describe why intelligence (Spearman's "g") can only be fully understood through "r-K" theory, which places it into an evolutionary framework along with brain size, longevity, maturation speed, and several other life-history traits. The "r-K" formulation explains why IQ predicts longevity and also why the gap in mortality rates between…
