Abstract Background Advances in paediatric critical care have resulted in a reduction in mortality. This has shifted the focus to paediatric intensive care unit (PICU)-related morbidities and how to reduce or prevent them. In this study, we aimed to study the impact of paediatric intensive care unit (PICU) admission on neurocognitive performance. Methods Intelligence quotient (IQ) was tested in 50 children (27 boys, 23 girls; mean age 6.98 years) 3 months after PICU discharge and in 75 controls using the Stanford-Binet IQ test. Results There was no statistically significant difference between patients and controls with regard to IQ scores, and no difference between medical and surgical patients (p > 0.05). IQ was unaffected by sedation, blood transfusion, or blood product transfusion. Patients who underwent a major surgical procedure, needed inotropic support, and needed mechanical ventilation had non-significantly lower IQ scores than those who did not. A non-significant negative correlation was observed between the length of PICU stay, mechanical ventilation duration, sedative use, and inotropic support. Conclusions PICU admission does not appear to significantly affect cognitive outcomes in paediatric survivors.

Prader-Willi syndrome (PWS) is a genomic imprinting disorder characterized by infantile hypotonia with a poor suck and failure to thrive, hypogenitalism/hypogonadism, behavior and cognitive problems, hormone deficiencies, hyperphagia, and obesity. The Stanford Binet and Wechsler (WAIS-R; WISC-III) intelligence (IQ) tests were administered on 103 individuals with PWS from two separate cohorts [University of California, Irvine (UCI) (N = 56) and Vanderbilt University (N = 47)] and clinical information obtained including growth hormone (GH) treatment, PWS molecular classes, weight and height. Significantly higher IQ scores (p

In this study, we apply "r" times the binomial transform to k-Lucas sequence. Also, the Binet formula, summation, generating function of this transform are found using recurrence relation. Finally, we give the properties of iterated binomial transform with classical Lucas sequence. [ABSTRACT FROM AUTHOR]

Chronic lung disease (CLD) in children represents a heterogeneous group of many clinico-pathological entities with risk of adverse impact of chronic or intermittent hypoxia. So far, few researchers have investigated the cognitive function in these children, and the role of auditory P300 in the assessment of their cognitive function has not been investigated yet. This study was designed to assess the cognitive functions among schoolchildren with different chronic pulmonary diseases using both auditory P300 and Stanford-Binet test. This cross-sectional study included 40 school-aged children who were suffering from chronic chest troubles other than asthma and 30 healthy children of similar age, gender and socioeconomic state as a control group. All subjects were evaluated through clinical examination, radiological evaluation and spirometry. Audiological evaluation included (basic otological examination, pure-tone, speech audiometry and immittancemetry). Cognitive function was assessed by auditory P300 and psychological evaluation using Stanford-Binet test (4th edition). Children with chronic lung diseases had significantly lower anthropometric measures compared to healthy controls. They had statistically significant lower IQ scores and delayed P300 latencies denoting lower cognitive abilities. Cognitive dysfunction correlated to severity of disease. P300 latencies were prolonged among hypoxic patients. Cognitive deficits in children with different chronic lung diseases were best detected using both Stanford-Binet test and auditory P300. P300 is an easy objective tool. P300 is affected early with hypoxia and could alarm subtle cognitive dysfunction. [ABSTRACT FROM AUTHOR]

This research evaluated the impact of a motor affordance intervention on motor and cognitive development. The sample included 46 healthy Iranian toddlers ages 24-42 months. The sample was randomly selected by multi-stage cluster sampling from a single community. The sample was divided into three groups: intervention ( n = 16), control-daycare ( n = 15) and a control ( n = 15). The intervention group was placed in an enriched motor affordance environment for 36 sessions over a 3-month period. All participants were pre and post-tested using the Affordances in the Home Environment for Motor Development- (AHEMD), Denver Developmental Screening Test п, and the Stanford-Binet Intelligence Scales. Data was analyzed using univariate and multivariate analysis of covariance. The key findings were that the motor affordance intervention had a positive effect on gross and fine-motor and cognitive development (verbal IQ subscale). [ABSTRACT FROM AUTHOR]

Introduction: Mental retardation is one of the most common disabilities of childhood which can be prevented by timely identification of the causative agent and an adequate management accordingly. District Kangra lies in the sub-Himalayan belt and forms a part of the 2400 km long goitre belt along the southern slopes of the Himalayas. Objective: To study the prevalence of mental retardation among children (1-10) years of age. Materials and Methods: A two-phase cross-sectional study was conducted in the rural area of district Kangra. A 30-cluster sampling technique was used to screen a population of children 1-10 years of age from five randomly selected panchayats (village government units) of district Kangra. The screening was based on a modified version of the ten questions screen, adapted to the local population. In the first phase a door to door survey was done to identify suspects of mental retardation. In the second phase, the children found positive in the first phase were called for examination by the pediatrician to confirm mental retardation. Results: A total of 2420 children were screened in the first phase of which 95 tested positive. About 52 of these children were found to be mentally retarded in the second phase giving a prevalence of 2.15%. The 69% of these children belonged to the lower middle class and 28.3% belonged to middle class families using the Uday Parekh scale for assessment of the socio-economic status. Conclusion: Prevalence of mental retardation is high in district Kangra of Himachal Pradesh in comparison to other states of India. This could be attributed to the good primary health care in Himachal Pradesh where institutional deliveries are about 70%. This may have led to better survival of children with congenital disorders and those that suffer perinatal trauma. [ABSTRACT FROM AUTHOR]

This study examined the underlying constructs measured by the Woodcock-Johnson Tests of Cognitive Abilities, Third Edition (WJ-III COG) and the Stanford-Binet Intelligence Scales, Fifth Edition (SB5), based on the Cattell-Horn-Carrol (CHC) theory of cognitive abilities. This study reports the results of the first joint confirmatory factor analysis of the WJ-III COG and SB5 with an independently collected preschool-aged sample. The WJ-III COG and SB5 were administered to 200 preschool-aged children of 4 to 5 with no known disorders or disabilities. Confirmatory factor analyses using maximum likelihood estimation were conducted to evaluate three models of increasing complexity and two alternative models to determine which model best describe the underlying constructs measured by the WJ-III COG and the SB5. Though none of the models displayed a good fit to the data, results showed that the underlying construct of the two tests was best represented by a Three-Stratum alternative CHC model in which the Gf factor and subtests were omitted. Exploratory factor analysis was conducted to provide further insights into the actual latent structure underlying the data. Implications of findings to guide school-based practitioners in using cross-battery assessment with preschool children were addressed. [ABSTRACT FROM AUTHOR]

Aim Cerebral palsy (CP) is defined as a primary disorder of posture and movement; however, approximately 45% of children with CP also have an intellectual impairment. Prevalence estimates are limited by a lack of guidelines for intelligence testing. This systematic review aims to identify and examine intelligence assessments for children with CP. Method Electronic databases (Pub Med, Psyc INFO, Web of Science, CINAHL, EMBASE, and ERIC) were searched to identify assessments that (1) measured intellectual function, (2) in children aged 4 to 18 years, (3) with CP, and (4) with psychometrics available. Results Searches yielded 48 assessments, of which nine provided psychometric data for children with CP. The included tests were the Columbia Mental Maturity Scale, the Leiter International Performance Scale, the Peabody Picture Vocabulary Test, the Pictorial Test of Intelligence, the Raven's Coloured Progressive Matrices, the Stanford-Binet Intelligence Scales, the Wechsler Adult Intelligence Scale, the Wechsler Intelligence Scale for Children, and the Wechsler Preschool and Primary Scale of Intelligence. Interpretation Intelligence assessments in children with CP lack reliability data, consensus regarding validity data, and population-specific norms. Research is required to establish psychometrics for children with CP. For children with higher motor involvement and/or communication and/or visual impairments, multiple options are required to assess intelligence appropriately. [ABSTRACT FROM AUTHOR]

Objective To examine the relationship between prenatal umbilical artery (UA) and internal carotid artery (ICA) Doppler findings and cognitive development at 3 and 6 years in low-birth-weight children. Methods This was a study of 209 low-birth-weight (< 10th centile) children born after 28 gestational weeks with UA resistance index (RI) measured within 2 weeks before delivery. Children with normal UA- and ICA-RI were defined as small-for-gestational age (SGA) and those with abnormal UA or ICA Doppler findings as having fetal growth restriction (FGR). Cognitive ability at 3 and 6 years' corrected age was assessed using the fourth edition of the Stanford-Binet Intelligence Scale (SBIS) and compared between SGA and FGR groups. An SBIS score < 85 was considered to indicate delayed development. Results The median gestational age at diagnosis of abnormal fetal growth was 36.6 (range, 28-41) weeks. There were 87 (41.6%) children classified as having FGR and 122 (58.4%) as SGA. The mean global SBIS score at 3 years was 109.4 (SD, 22.8) and at 6 years it was 110.5 (SD, 13.9). Overall, 22 (10.5%) children had delayed development at 3 years. Total SBIS scores and individual domain scores did not differ between FGR and SGA groups at 3 or 6 years and similar proportions in each group had delayed development. Conclusion Abnormal prenatal UA and ICA Doppler findings are not associated with lower developmental scores in low-birth-weight children delivered in the third trimester of pregnancy.

A review of hospital records was conducted for children evaluated for autism spectrum disorders who completed both the Leiter International Performance Scale-Revised (Leiter-R) and Stanford-Binet Intelligence Scales, 5th Edition (SB5). Participants were between 3 and 12 years of age. Diagnoses were autistic disorder (n = 26, 55%) and pervasive developmental disorder-not otherwise specified (n = 21, 450/0). Analysis showed that the full sample received significantly higher scores on the Leiter-R than SB5 (mean discrepancy of 20.91 points), specific diagnosis was not a significant factor, and younger children had a larger discrepancy between tests. These analyses strongly suggest that the Leiter-R and the SB5 may not be equivalent measures of intellectual functioning in children with autism spectrum disorders, and that use of one or the other exclusively could lead to misclassification of intellectual capacity.

Abstract: This study reports on the relationship between motor stereotypies and impairments in executive functions (EF) in children with Autistic Disorder (AD) and in children with Developmental Language Disorders (DLD). We hypothesized that low EF performance would predict higher frequency and longer durations of stereotypies in the AD group only. Twenty-two children (age range=7–9 years, 6 months, girls=5) with AD were recruited from a longitudinal multi-site study and compared to twenty-two non-autistic children with DLD (age range=7–9 years, 6 months, girls=5). The two groups were matched on non-verbal IQ and demographic characteristics. Frequency and duration of stereotypies were coded from videotaped semi-structured play sessions. EF measures included the Wisconsin Card Sorting Task (WCST) Categories, Wechsler Intelligence Scale for Children-Revised (WISC-R) Mazes, and Stanford-Binet Fourth Edition (SB-IV) Matrices. The scores for frequency and duration of stereotypies were higher in the AD group. Separate linear regressions revealed that group status, EF, and their interactions predict stereotypies. Specifically, lower EF scores predicted higher frequencies and longer durations of stereotypies in the AD group only. Analyses controlled for age, gender, and parent education. Findings suggest that in AD, EF impairments and stereotypies may be linked to shared brain pathways. [Copyright &y& Elsevier]

There are two reasons why the Terman Scale produces IQ values significantly and progressively higher than those obtained with the currently used factor scales: the irregular variability of IQ among different age and ability levels (atypical variability) and the results becoming outdated as time goes on. Based on the thesis that the performance of the individuals tends to form distributions of typical derivative scorings and from the determination of the natural variability characteristic of the Terman scales, we define a General Psychometric Model which is related to the models of the factor scales. Next, we propose a procedure to correct the atypical variability and to determine Proportional Alternative Rules. Lastly, the peculiar pattern of the outdated IQ of the age scales (the IQ dynamics) is described, and an estimation of the actual IQ values is provided using the proportional rules.

Measures of visual-motor integration skills continue to be widely used in psychological assessments with children. However, the construct validity of many visual-motor integration measures remains unclear. In this study, we investigated the relative contributions of maturation and cognitive skills to the development of visual-motor integration skills in young children (N = 856). We used a block regression analysis to determine the contribution of maturation, as indicated by age, followed by broad cognitive factors (Study 1) and subsequently by individual subtests in verbal and nonverbal domains subsumed under each factor (Study 2) in explaining score variance of the Bender Visual-Motor Gestalt Test (2nd ed.; BG-II; Brannigan & Decker, 2003) Copy and Recall scores in children between the ages of 4 and 7 years. Results confirm that maturation accounted for a large proportion of variance in both BG-II Copy and Recall performance, above which Stanford-Binet Intelligence Scale (5th ed.; SB-5; Roid, 2003) Quantitative Reasoning and Fluid Reasoning factors significantly contributed to visual-motor integration performance for the Copy phase, and SB-5 Quantitative Reasoning and Visual-Spatial factors accounted for a significant amount of variance for the Recall phase. Additionally, nonverbal domains were more related to visual-motor performance than verbal domains. Results from this study are interpreted to suggest nonverbal reasoning and visual-spatial attention are important contributing factors to visual-motor integration, as measured by the BG-II. Developmental implications of visual-motor integration skills, nonverbal problem solving, and mathematical competence are discussed. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine the factor structure of the Stanford-Binet Intelligence Scales, Fifth Edition (SB-V), based on the Cattell-Horn-Carroll (CHC) theory of intelligence using a sample of 200 preschool children. The CHC framework uses three different models: one similar to Spearman's g, one similar to the Gf-Gc model, and one representing the hierarchical three-stratum CHC model. A confirmatory factor analysis (CFA), utilizing these three models, was conducted to determine which theoretical model best described the ability structure measured by the SB-V. Results of the CFA revealed that, although the two-stratum model provided the best fit statistics, a large amount of overlap existed among the broad CHC factors in this model. Therefore, these results suggested that a simple, overall ability model may be the best representation of ability for preschool children when using the SB-V because the factors appeared to be indistinct with this age group. © 2011 Wiley Periodicals, Inc.

Chronic lymphocytic leukemia (CLL) has a high prevalence in western countries and remains incurable to date. Here, we provide evidence that the multikinase inhibitor sorafenib induces apoptosis in primary CLL cells. This strong pro-apoptotic effect is not restricted to any subgroup of patients, based on Binet stage and the expression of ZAP70 or CD38. Mechanistically, sorafenib-induced cell death is preceded by a rapid downregulation of Mcl-1 through the inhibition of protein translation. Subsequently, the cell intrinsic apoptotic pathway is activated, indicated by destabilization of the mitochondrial membrane potential and activation of caspase-3 and -9. In contrast to sorafenib, the monoclonal vascular epidermal growth factor (VEGF)-antibody bevacizumab failed to induce apoptosis in CLL cells, suggesting that sorafenib induces cell death irrespectively of VEGF signalling. Notably, although sorafenib inhibits phosphorylation of the Scr-kinase Lck, knock-down of Lck did not induce apoptosis in CLL cells. Of note, the pro-apoptotic effect of sorafenib is not restricted to cell-cycle arrested cells, but is also maintained in proliferating CLL cells. In addition, we provide evidence that sorafenib can overcome drug resistance in CLL cells protected by microenvironmental signals from stromal cells. Conclusively, sorafenib is highly active in CLL and may compose a new therapeutic option for patients who relapse after immunochemotherapy. [ABSTRACT FROM AUTHOR]

This study investigated whether mothers of children assessed as having gifted/high IQ at 5 years were more likely to scaffold their children in analogical and metacognitive thinking during the infant/toddler period than mothers of children with more typical IQs. The researcher videotaped 21 children in monthly play sessions with their mothers, from the time that the children were 8 months old until they were 17 months old, and coded the mothers' verbalizations for scaffolding of analogical and metacognitive thinking. A psychologist assessed these children on the Stanford-Binet IV (Thorndike, 1986) and found ability levels ranging from average to high. Analysis showed that mothers of the children with high IQs introduced analogical and metacognitive scaffolding earlier than mothers of children with average IQs. The findings are consistent with a bidirectional model of gifted development in which mothers respond, to support advanced development from infancy. [ABSTRACT FROM AUTHOR]

The Stanford-Binet Intelligence Scale, Fifth Edition (SB5), is a recently published, multidimensional measure of intelligence based on Cattell-Horn-Carroll (CHC) theory. The author of the test provides results from confirmatory factor analyses in the technical manual supporting the five-factor structure of the instrument. Other authors have examined this factor structure through EFA using the standardization sample, and have not found evidence of a five-factor model. The purpose of the current study was to examine the internal construct validity of the SB5 using an independent sample of high-functioning students. Participants included 201 high-functioning, third-grade students ranging in age from 8 years, 4 months to 10 years, 11 months. Five models of the SB5 were analyzed using Analysis of Moment Structures (AMOS). Our findings indicated that a hierarchical, four-factor, post-hoc model provided the best fit to the data. Generally, implications for school psychologists include a better understanding of the factor structure of the SB5, especially as it relates to high-achieving children. Directions for future research are also discussed. [ABSTRACT FROM AUTHOR]

Type 1 diabetes mellitus is associated with cognitive changes, but the extent of cognition decline depends on age at onset, duration of diabetes, and occurrence of attacks of hypoglycemia or ketoacidosis. This study was designed to assess cognitive function in a group of children with type 1 diabetes mellitus. A total of 40 diabetic children were recruited from the pediatric department of Assiut University Hospital, Egypt. Forty healthy children matched for age, sex, and socioeconomic status were chosen as controls for comparison. Cognition was assessed using Stanford-Binet and event-related potentials tests. Compared to the control group, patients reported a significant reduction in intelligent quotient, comprehension, abstract visual reasoning, quantitative reasoning, bead memory, and total short memory testing for cognitive functions. Prolonged N1, P200, N2, and P300 latencies and reduced P300-N2 amplitude were reported. Significant negative correlations were identified in most studied cognitive functions and ketoacidosis or family history of diabetes mellitus. [ABSTRACT FROM AUTHOR]

The article presents a case study of an 11-year-old girl who was found to have thrombocytopenia during preoperative evaluation for ear tube insertion. He had a history of a frequent epistaxis since infancy, delayed speaking, and learning difficulty at school. Audiogram test showed bilateral sensorineural deafness with mild mental retardation based on the Stanford-Binet Intelligence Scale. Chromosome analysis was then initiated using a high-resolution binding technique.

Abstract: Stanford-Binet and Wechsler Adult Intelligence Scale (WAIS) IQs were compared for a group of 74 adults with intellectual disability (ID). In every case, WAIS Full Scale IQ was higher than the Stanford-Binet Composite IQ, with a mean difference of 16.7 points. These differences did not appear to be due to the lower minimum possible score for the Stanford-Binet. Additional comparisons with other measures suggested that the WAIS might systematically underestimate severity of intellectual impairment. Implications of these findings are discussed regarding determination of disability status, estimating prevalence of ID, assessing dementia and aging-related cognitive declines, and diagnosis of ID in forensic cases involving a possible death penalty.

The Terman scale (Stanford-Binet Terman-Merrill Third Edition, also known as Form L-M) was generally used in Spain until the late 70s. Presently its use is marginal and restricted almost exclusively to the evaluation and diagnosis of students with a possible high intellectual capacity. During the last few years parents have increasingly requested (and sometimes demanded) the use, or at least the consideration of the results of the scale. The purpose of this article is to present, from the main characteristics of the scale, the fundamental arguments against its use at present and in favour of disregarding its results: (1) absence of valid norms, (2) heterocedasticity, (3) effects of the change in the nature of IQ, (4) difficulties of integration within the context of psychopedagogical evaluation, and (5) difficulties assimilating the concept of mental age for the recipients.

Abstract: This study evaluated the clinical utility of the Stanford-Binet-5 (SB-5) in assessing individuals suspected of having an autism spectrum disorder (ASD). Comparisons were made between individuals with and without autism (AD), with or without comorbid mental retardation. Differences in score profiles were discovered based on AD and mental retardation (MR) status. Score differences were then evaluated using VIQ as a covariate. Findings suggested that verbal ability has a large influence on scores, even within the nonverbal subtests. Discriminant analysis revealed that SB-5 scores could predict group membership with 52.9% accuracy among the four groups, and with 82.6% accuracy when determining between MR and MR with AD.

Background and Aims: Some studies have shown low school performance of children with early-onset unilateral sensorineural hearing loss (U-SNHL). We undertook this study to compare cognitive performance of school-children with perinatal U-SNHL with that of a group of bilateral normal hearing (BNH) children. Methods: We performed a cross-sectional observation from our prospective study that included children discharged from the Neonatal Intensive Care Unit (NICU) who were followed to determine their hearing, language, and neurocognitive development. We performed audiometric studies and Stanford-Binet intelligence scale after Terman-Merrill version examinations. Statistical comparisons were carried out with Student t and χ2 tests. We calculated U-SNHL-associated relative risk with a 95% confidence level. Results: We followed 21 children with U-SNHL and 60 with BNH. Median age of both groups at the time of study was 7 years. Hearing loss severity ranged from severe to profound. Average number of days of stay at the NICU in the U-SNHL group was 26±4 days, whereas for the BNH group this was 8±2 days (p <0.001). U-SNHL-associated variables included hyperbilirubinemia, bronchopulmonary dysplasia, furosemide exposure, and hypoglycemia. Average and standard deviation of total and of both Terman-Merrill intelligence subscale coefficients were significantly lower in the U-SNHL group. Conclusions: Children with U-SNHL may present lower intelligence coefficients than children with BNH. It is important to observe whether this handicap continues throughout the child''s lifetime and to ascertain whether there are certain factors associated with reversibility of disability.

Abstract: In order to better define the effects of methylmercury (MeHg) exposure on neurodevelopment, qualitative error types observed in the responses of exposed children to the Stanford–Binet Copying Test were categorized and quantified using raw data from two studies of 395 Amazonian children aged 7–12 years (from Brazil and French Guiana). These outcomes were related to hair-mercury concentration as the biomarker of MeHg exposure (range=0.5–63.8μg/g). The combined analysis of data from two separate countries had two major goals: (1) to gain clues concerning the underlying neuropathological mechanisms of observed effects based on convergent evidence of MeHg-related qualitative outcomes in the two studies and (2) to explore possible cultural determinants of test response based on divergent outcomes in the two countries. Multiple linear and logistic regression analyses were performed with adjustment for confounders. In the combined data set, mercury exposure was negatively associated with scores on the drawing task: a score reduction of 1.2 (s.e., 0.3) points was observed in the children with a hair-mercury concentration above 10μg/g compared to those with a hair level below 1μg/g; this effect appeared to be stronger in the younger children. Risk of committing one or more errors of rotation, simplification or perseveration in the drawings increased with hair-mercury concentration in both cultural settings, providing convergent evidence of specific types of MeHg-related neurocognitive outcomes. However, relationships between mercury exposure and scores on the Block organization component of the test varied according to the study site, indicating that other factors must be considered in evaluating responses to the demands of this cognitive task.

Orthogonal higher-order factor structure of the Stanford-Binet Intelligence Scales-Fifth Edition (SB-5; Roid, 2003a) for child and adolescent samples is reported. Multiple criteria for factor extraction unanimously supported extraction of only one dimension and a unidimensional model. However, following results from DiStefano and Dombrowski (2006) and theoretical consideration, two factors were extracted and obliquely rotated and further subjected to the Schmid and Leiman (1957) procedure using MacOrtho (Watkins, 2004). Results showed that the largest portions of total and common variance were accounted for by the second-order, global ('g') factor and interpretation of the SB-5 should focus primarily, if not exclusively, on the general, Full Scale IQ. No evidence for a five-factor solution was found. [ABSTRACT FROM AUTHOR]

This study examined the accuracy of three shortened measures of intelligence: the Woodcock–Johnson Tests of Cognitive Ability, Third Edition Brief Intellectual Ability (WJ III COG BIA) score; the Stanford–Binet Intelligence Scale, Fifth Edition Abbreviated IQ (SB5 ABIQ); and the Kaufman Brief Intelligence Test IQ Composite (K-BIT) in predicting giftedness as assessed by the SB5 Full Scale IQ score (SB5 FSIQ). Participants were 202 third grade students who were individually administered the SB5, WJ III, and K-BIT. Four scores (SB5 ABIQ, K-BIT, WJ III COG BIA, and SB5 FSIQ) were extracted. Correlational analyses revealed positive, significant relationships among the four scores. Discriminant function analyses, conducted to examine the accuracy of the three shortened measures of intelligence in predicting giftedness, revealed that overall, the WJ III score was the most accurate, and the K-BIT score was the least accurate in identifying giftedness. © 2008 Wiley Periodicals, Inc.

Purpose: Using a sample of culturally/linguistically diverse children, we present data to illustrate the value of empirically derived combinations of tools and cutoffs for determining eligibility in child language impairment. Method: Data were from 95 4- and 6-year-olds (40 African American, 55 White; 18 with language impairment, 77 without) who lived in the rural South; they involved primarily scores from the Comprehension subtest of the Stanford-Binet Intelligence Scale--Fourth Edition (CSSB; R. Thorndike, E. Hagen, & J. Sattler, 1986), but scores from an experimental nonword repetition task (NRT; C. Dollaghan & T. Campbell, 1998) were also included as supplements to these scores. Results: Although the CSSB led to low fail rates in children without impairment and a statistically reliable group difference as a function of the children's clinical status but not their race, only 56% of children with impairment were accurately classified when -1 SD was employed as the cutoff. Diagnostic accuracy improved to 81% when an empirically derived cutoff of -.5 SD was used. When scores from the NRT were added to those from the CSSB, diagnostic accuracy increased to 90%. Implications: This illustrative case adds to the growing number of studies that call for empirically derived combinations of tools and cutoffs as one option within an evidence-based practice framework.

Does visual working memory represent a fixed number of objects, or is capacity reduced as object complexity increases? We measured accuracy in detecting changes between sample and test displays and found that capacity estimates dropped as complexity increased. However, these apparent capacity reductions were strongly correlated with increases in sample-test similarity ( r= .97), raising the possibility that change detection was limited by errors in comparing the sample and test, rather than by the number of items that were maintained in working memory. Accordingly, when sample-test similarity was low, capacity estimates for even the most complex objects were equivalent to the estimate for the simplest objects ( r= .88), suggesting that visual working memory represents a fixed number of items regardless of complexity. Finally, a correlational analysis suggested a two-factor model of working memory ability, in which the number and resolution of representations in working memory correspond to distinct dimensions of memory ability.

Elementary students in programs for gifted and highly gifted students were tested using the Stanford-Binet Intelligence Scales, Fifth Edition (SB5). Students' scores on the SB5 were significantly lower than their scores on the Wechsler Intelligence Scale for Children--Third Edition (WISC-III). In addition, rank order was not well preserved between the SB5, WISC-III scores, and determination of giftedness. While the cause of these findings is unclear, caution should be used when utilizing the SB5 for determinations of gifted status. [ABSTRACT FROM AUTHOR]

Two related studies investigated sex differences in self- and parental estimates of IQ scores on specific scales derived from standardized and validated IQ tests. In the first study 210 participants were asked to estimate their scores on the 11 WAIS-R subtests as well as their overall general IQ. Results showed males estimated their overall score, plus their total WAIS score, significantly higher than females, with effect sizes around 0.5. Factor analysis showed participants did differentiate between verbal and performance subscale scores on this test. In the second study 117 participants performed a similar task, but this time on the 12 subscales of the Stanford-Binet test. Males estimated their overall score higher than females. Factor analysis also showed 2 clear factors that reflected exactly the verbal and performance subscale scores. [ABSTRACT FROM AUTHOR]

Recent research suggests that childhood cognitive performance is associated with various health outcomes, but the nature of the relation is not well understood. It is unclear whether the association occurs across the continuum of cognitive performance, and if it is independent of socioeconomic status. Prospective data from the Terman Life Cycle Study were used to evaluate the hypothesis of a monotonic relation between childhood intelligence quotient (IQ) and adult mortality and to determine whether there exists a threshold beyond which the protective effects of IQ are no longer evident. A total of 897 individuals of school age who scored 135 or higher on the Stanford-Binet IQ test were recruited in 1922. Cox proportional hazards regression was used to estimate survival over a 64-year period. A 15-point advantage in childhood IQ was significantly associated with a decreased risk of mortality (hazard ratio = 0.68, 95% confidence interval: 0.49, 0.93) for IQ scores up to 163; beyond that, the risk of death plateaued. Results were similar when the sample was limited to those participants whose fathers had nonmanual occupations. Childhood IQ, even at the upper end of the distribution, is a significant predictor of mortality, independent of childhood social position. [ABSTRACT FROM AUTHOR]

Stanford Binet: Fourth Edition (SB:IV) assessments have been collected longitudinally for 195 individuals with Down syndrome. This article discusses individual assessments which were selected for their ability to highlight major concerns that practitioners need to consider when interpreting intelligence test scores with this population. In this study, Intelligence Quotient (IQ) changed substantially for many individuals, demonstrating changes in classification from a mild level of intellectual impairment on initial assessment to a severe level on later assessment. Subtests used in calculating composite scores were found to have a dramatic effect on IQ. There was up to 9 IQ points difference depending on whether only the ’core’ subtests or all subtests used by the assessor were included in the calculations. Thirty-seven percent of the assessments were at ’floor level’ (i.e., IQ of 36), despite obvious divergent abilities illustrated by age equivalent scores. Mean Age Equivalent (MAE) scores were also problematic as they failed to adequately represent either the range, or divergence, of abilities of the individuals whose data are presented. Directions for future research are discussed. [ABSTRACT FROM AUTHOR]

Objective: To explore concurrent and predictive validity of the Stanford-Binet: Fourth Edition (SB-IV) by comparing scores on the SB-IV with scores from the Battelle Developmental Inventory (BDI) and later achievement scores in preschoolers at risk due to very low birthweight, and/or intraventricular hemorrhage (IVH) and other medical complications.Methods: At ages 3,4, and 5, 92 preschoolers were tested with the SB-IV and BDI as part of an 8-year early intervention follow-up.Results: The SB-IV and BDI concurrent correlations at ages 3, 4, and 5 were statistically significant (r = .73-.78, p < .0001), as were predictive correlations (r = .58-.85, p < .0001). However, the BDI and SB-IV failed to place the children in the same categories for intervention services. With the BDI as the comparison measure, SB-IV failed to detect 87% of the children who were "delayed" (by BDI) at age 3 and 50% of the "delayed" children at age 5.Conclusions: Caution is recommended when using the SB-IV to assess high risk for early intervention eligibility.
