Performance in elementary cognitive tasks is moderately correlated with fluid intelligence and working memory capacity. These correlations are higher for more complex tasks, presumably due to increased demands on working memory capacity. In accordance with the binding hypothesis, which states that working memory capacity reflects the limit of a…

We examined the response to a phonics through spelling intervention for children with developmental dyslexia in word and pseudoword reading efficiency and word spelling. Furthermore, we investigated to what extent the response to the intervention is robust across different cognitive profiles (phonological awareness, rapid automatized naming, and…

Lynn (2010a, 2010b) argued that individuals from south Italy have a lower IQ than individuals from north Italy, and that these differences in IQ are at the basis of north-south gap in income, education, infant mortality, stature, and literacy. In the present paper, we discuss several theoretical and methodological aspects which we regard as flaws…

The purpose of this commentary is to focus on the clinical utility of the four- and five-factor structural models for the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) and Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). It provides a discussion of important considerations when evaluating the clinical utility of the…

We investigated whether preschool children with specific language impairment (SLI) exhibit the shape bias in word learning: the bias to generalize based on shape rather than size, color, or texture in an object naming context ("This is a wek; find another wek") but not in a non-naming similarity classification context ("See this?…

The interpretation of retest scores is problematic because they are potentially affected by measurement and predictive bias, which impact construct validity, and because their size differs as a function of various factors. This paper investigates the construct stability of scores on a figural matrices test and models retest effects at the level of…

The study was conducted to determine differences in the authoritarianism dimensions of men and women and between individuals of above average and superior intelligence. The males scored significantly higher on three dimensions. Individuals of above average intelligence scored significantly higher than those of superior intelligence on three…

To clarify the relationships between reaction time (RT) variability and intelligence, RT distributions from 303 male Navy recruits were partitioned into 16 fast-to-slow latency bands calculated with measures of mental ability. The slowest bands (worst trials) were the best predictors of intelligence and working memory performance. (SLD)

Self-concept, intelligence and academic achievement were examined in students preparing to teach in primary, elementary, secondary, and special education (N=267). Differences in self-concept, but not in intelligence and academic achievement, were found among groups of student teachers. (Author)

THE POSSIBLE EFFECTS OF FLES UPON STUDENT ACHIEVEMENT IN OTHER SUBJECT AREAS WAS THE BASIC PROBLEM OF A STUDY IN THE HICKSVILLE, N.Y. PUBLIC SCHOOLS. FOLLOWING A SURVEY OF LITERATURE ON THE PROS AND CONS OF FLES PROGRAMS, THE REPORT CONSIDERS THE PERFORMANCE OF THE EXPERIMENTAL GROUP, WITH CONTINUOUS FLES INSTRUCTION STARTING IN THE FIRST GRADE,…

The objective of this study was to empirically validate West Germans' classifications of 11 attributions according to dimensions of locus, stability, controllability, predictability, and globality. The West German sample was then compared to an American sample. It is believed that West Germans and Americans develop different beliefs about the…

A study involving 46 intellectually talented and 46 typical third graders was undertaken to assess differences in psychosocial maturity across the groups. Focus was on examining psychosocial maturity through assessment of interpersonal reasoning, which is defined as the ways children exhibit sensitivity to the feelings of others and assume…

Intelligence tests are really only systems of classification of individuals with reference to others. Thus with such classification systems it is impossible to interpret a deficiency reflected by test scores in other than a socio-cultural frame of reference. Some 150 Black and White seventh grade children between the ages of 12 and 14 were…

The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…
