DSM-5, the fifth edition of the American Psychiatric Association's "Diagnostic and Statistical Manual of Mental Disorders," was published in May 2013, amidst a storm of controversy. This article focuses on changes made to the diagnostic criteria for Specific Learning Disorders (SLD). Primary criticisms of the changes in the SLD concern…

There is growing evidence supporting the importance of executive functions, and specifically working memory updating (WMU), for children's academic achievement. This study aimed to assess the specific contribution of updating to the prediction of academic performance. Two updating tasks, which included different updating components, were…

Many recent studies have aimed to demonstrate that specific types of reading comprehension depend on different underlying cognitive abilities. In these studies, it is often implicitly assumed that reading comprehension is a multidimensional construct. The general aim of this study was to examine the dimensionality of a large pool of reading…

The purpose of this study was to examine child-level pathways in development of prealgebraic knowledge versus word-problem solving, while evaluating the contribution of calculation accuracy and fluency as mediators of foundational skills/processes. Children (n = 962; mean 7.60 years) were assessed on general cognitive processes and early…

Purpose: To gain a better understanding of the cognitive processes supporting verbal abilities, the underlying structure and interrelationships between common verbal measures were investigated. Methods: An epidemiological sample (n = 374) of school-aged children completed standardized tests of language, intelligence, and short-term and working…

The goal of this study was to determine whether intensive training can ameliorate cognitive skills in children. Children aged 7 to 9 from low socioeconomic backgrounds participated in one of two cognitive training programs for 60 minutes/day and 2 days/week, for a total of 8 weeks. Both training programs consisted of commercially available…

A cohort of 87 Latino elementary school students participated in a study to identify factors predictive of the math reasoning and math computation performance levels. Multiple regression analyses were used to determine which of the five blocks or combination of blocks were significantly predictive of performance levels on two standardized academic…

In 2004 national educational standards for chemistry were implemented in Germany. While the standards describe different competencies to be reached after grade 10, no compulsory contents are defined. The contents are defined by the different German states individually. This means that there are no defined common topics taught in all states that…

Currently, American schooling, driven by No Child Left Behind (NCLB) and standardized tests, emphasizes development of intelligence. Because of this, teachers must heavily emphasize acquisition of foundational information (facts) in lectures, assessments, and of course, time-consuming test preparation, at the expense of intellect, that…

Objectives: To demonstrate that high IQ adults diagnosed with ADHD suffer from executive function (EF) impairments that: a) can be identified with a combination of standardized measures and self-report data; and b) occur more commonly in this group than in the general population. Method: 157 ADHD adults with IQ greater than or equal to 120 were…

Argues that IQ tests work only for some people some of the time. Offers a theory that emphasizes the roles in intelligence of information-processing, the environmental context, and coping with novelty and automatization of task performance, as a possibility for improving levels of prediction. (CMG)

This study determined which intellectual abilities account for IQ changes over the school year. All the Head Start subjects involved in the study (35 boys and 33 girls, mean age 44.1 months) lived in poverty under conditions of urban deterioration. The subjects were initially given the Standord-Binet Intelligence Scale in the fall and were tested…

The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…

There is a debate about whether the language of children with primary language disorders and normal cognitive levels is qualitatively different from those with language impairments who have low or borderline non-verbal IQ (NVIQ). As children reach adolescence, this distinction may be even harder to ascertain, especially in naturalistic settings.…
