Though several studies have been undertaken to explore the correlates of academic achievement, there is a dearth of studies relating to the cognitive profiles of children who show marked discrepancies between their cognitive potential and actual academic achievement. The present study was undertaken in this context. The study was conducted on a…

The purpose of this study is to construct and evaluate diagnostic battery tests of verbal and non-verbal learning disabilities for students in the Arabic schools. 612 students were in the 3rd, 4th and 5th grades of primary school were involved, mostly from Egypt and Saudi Arabia. Their ages ranged from 7.94-10.98 with mean age = 9.62 and SD =…

Childhood socioeconomic status (SES), as measured by parental education and family income, is highly predictive of academic achievement, but little is known about how specific cognitive systems shape SES disparities in achievement outcomes. This study investigated the extent to which executive function (EF) mediated associations between parental…

This study investigated the relationship between syntactic comprehension at the sentence level and text-level comprehension. The study isolated the specific contribution of syntax by asking whether sentence comprehension efficiency of difficult syntactic constructions explained variance in text comprehension after controlling for sentence…

Aim: The aim of this article was to explore the effect of duration of breastfeeding on neurocognitive development. Method: The long-term effect of breastfeeding on neurodevelopment was examined through a battery of neuropsychological tests in 1403 children (693 females, 710 males; mean age 11y 9mo [SD 6mo], range: 10y 3mo-12y 8mo) who were…

Children with nonverbal learning disabilities (NVLD) have been found to be worse at recognizing facial expressions than children with verbal learning disabilities (LD) and without LD. However, little research has been done with adolescents. In addition, expressing and understanding facial expressions is yet to be studied among adolescents with LD…

A learning disability index (LDI) based on a principal components analysis of the Weschler Intelligence Scale for Children-Revised normative data has been developed to depict verbal or nonverbal deficits on that test. Ss (N=1550) referred for educational difficulties returned mean scores on the LDI that were reliably different from expected scores…

The paper provides a theoretical framework for the inclusion of a verbal intelligence test as part of the psychodiagnostic assessment battery used with deaf children. Descriptions are provided for three selected sign language varieties being used in a study designed to examine performance of 30 deaf children (9-16 years old) on signed…

Wide Range Achievement Test arithmetic scores related to Wechsler Intelligence Scale for Children-Revised freedom from distractibility and perceptual organization scores as well as simultaneous processing. Educable mentally retarded childrens' reading problems may relate to failure to apply verbal intellectual abilities to academic tasks. (Author)

Cognitive self-instructional (CSI) programs have been successful in improving problem-solving skills in many, but not all, children. The importance of understanding the influence of subject characteristics in self-control studies, while often ignored in actual research, has been repeatedly advocated verbally. This paper presents a study designed…

The study sought to use Jensen's two-level theory of mental abilities to predict some hitherto unknown or unnoticed phenomena--facts about which the theory should yield clear-cut predictions and which are not as clearly predictable from other theories, though they may receive ad hoc explanations after the fact. From the two-level theory of mental…

This study examined whether Wechsler Intelligence Scale for Children (Revised) subtest patterns employing Kaufman's classification system differ between male and female elementary grade students receiving special education services. It also examined whether females in special education are more significantly impaired than males, and whether males…
