Comparison of the General Ability Measure for Adults and the Kaufman Adolescent and Adult Intelligence Test with college students

PSYCHOLOGY IN THE SCHOOLS, Issue 5 2002
Kerry S. Lassiter
Ninety-four college students were administered the GAMA and KAIT. GAMA IQs were significantly and moderately correlated with KAIT Fluid, Crystallized and Composite IQs, supporting the convergent validity of this instrument. Although significant correlations between measures emerged and nonsignificant differences were found between mean scores across these instruments, GAMA IQ scores did not accurately predict KAIT Composite IQ scores when GAMA IQ scores were compared to KAIT Composite IQs. Similarly, when the sample was divided into two groups by ability level, GAMA IQs accurately estimated the intelligence for individuals of Average and Below Average intelligence, but underestimated the KAIT Composite IQ scores by 4 points for the Above Average group. Implications of the findings are discussed and suggestions for future research are provided. 2002, Wiley Periodicals, Inc. [source]


Immediate effects of methylphenidate on cognitive attention skills of children with attention-deficit-hyperactivity disorder

Jane Hood MSc
This study investigated the immediate effects of stimulant medication (methylphenidate) on cognitive attention processes in children with attention-deficit-hyperactivity disorder (ADHD). Thirteen males and two females (mean age 9y 5mo, SD 18.3mo) with a diagnosis of ADHD and who were to be prescribed methylphenidate were assessed twice on one day with the Test of Everyday Attention for Children, a neuropsychological battery designed to tap different aspects of cognitive attention. Between assessments, the children were administered methylphenidate (10mg). Each child had at least average intelligence (IQ 80 or over, as measured by the Wechsler Intelligence Scale for Children - III UK) and was on no other medication. A group of 16 children, who were matched for age, sex, and intelligence, also performed the cognitive tests twice on the same day to control for practice effects of testing. At the first assessment, children with ADHD demonstrated significant impairments in several aspects of cognitive attention in comparison with the control group, particularly sustained attention. After administration of methylphenidate for the children with ADHD, they showed significant improvements in their performance on measures of cognitive attention compared to controls. The immediate effects of methylphenidate and the significance of measuring cognitive aspects of attention as well as behavioural measures are discussed. [source]


Core neuropsychological characteristics of children and adolescents with 22q11.2 deletion

JOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 8 2010
C. Jacobson
Abstract Background The 22q11.2 deletion syndrome (22qDS) confers high risk for intellectual disability and neuropsychological/academic impairment, although a minority of patients show average intelligence. Intellectual heterogeneity and the high prevalence of psychiatric diagnoses in earlier studies may have obscured the prototypical neuropsychological profile in 22qDS. Methods We examined intelligence, memory, reading and mathematical processes in 31 children/adolescents with 22qDS, selected for educational underachievement and an absence of psychiatric diagnoses, using standardised, psychometrically matched instruments that specify how typical a score is for a given intelligence quotient (IQ). Results Corroborating earlier findings, verbal IQ was significantly superior to performance IQ; verbal memory and basic reading were relative strengths; and visual/spatial memory was a relative weakness. All four findings transcended performance characteristics that are typical of low-IQ individuals. Rote learning yielded the highest score; reading comprehension, numerical operations and mathematical reasoning were among the lowest-performed academic domains. Albeit in the expected direction, performance in the respective components could not be clearly differentiated from what is IQ-appropriate. Conclusions A superiority of verbal intelligence over non-verbal intelligence, relative strengths in verbal memory and basic reading, and a relative weakness in visual/spatial memory are likely to be core characteristics of children/adolescents with 22qDS, transcending performance features that are typical of individuals with low IQ.

The Impact of Intelligence and Institutional Improvements on Economic Growth

KYKLOS INTERNATIONAL REVIEW OF SOCIAL SCIENCES, Issue 3 2002
Erich Weede
Standard indicators of human capital endowment , like literacy, school enrollment ratios or years of schooling , suffer from a number of defects. They are crude. Mostly, they refer to input rather than output measures of human capital formation. Occasionally, they produce implausible effects. They are not robustly significant determinants of growth. Here, they are replaced by average intelligence. This variable consistently outperforms the other human capital indicators in spite of suffering from severe defects of its own. The immediate impact of institutional improvements, i.e., more government tolerance of private enterprise or economic freedom, on growth it is in the same order of magnitude as intelligence effects are. The senior author is responsible for picking a ,politically incorrect' topic, i.e., analyzing the impact of IQ or average intelligence. The junior author has done the data compilation and the computations. [source]


Promoting Strategic Learning by Eighth-Grade Students Struggling in Mathematics: A Report of Three Case Studies

LEARNING DISABILITIES RESEARCH & PRACTICE, Issue 3 2005
Deborah L. Butler
Participants were three eighth-grade students enrolled in a learning assistance classroom who were of at least average intelligence but who were performing significantly below grade level in mathematics. These case studies document the processes by which these students were supported to self-regulate their learning in mathematics more effectively. We begin by outlining important instructional foci in mathematics education for intermediate or secondary students with learning disabilities, along with what research indicates are effective instructional processes. In that context, we introduce the theoretical principles underlying the instructional model used here,Strategic Content Learning (SCL). Based on analyses of case study data, we describe how SCL instruction was structured to promote strategic learning. Throughout the discussion, intervention processes are described in sufficient detail to be of use to practitioners. [source]
