A considerable about of research has concentrated on studying the performance of high achieving children on measures of intellectual functioning. Findings have indicated high achieving children display differences in performance patterns as well as in the cognitive constructs measured when compared to their average peers. The conceptualization of intelligence has evolved over time and contemporary theories of intelligence have described cognitive ability as consisting of multiple constructs which are often interrelated. Currently. one of the most comprehensive and empirically supported theories of intelligence is the Cattell-Horn-Carroll (CHC) theory (Cattell, 1941; Horn, 1968: Carroll, 1993). The multidimensional and hierarchical CHC theory has served as the foundation for the development and recent revisions of cognitive ability measures such as the Woodcock-Johnson Tests of Cognitive Ability– Third Edition (WJ-III COG; McGrew & Woodcock 2001) and the Stanford-Binet Intelligence Scales – Fifth Edition (SBS: Raid, 2003b). The purpose of this study was to explore the construct validity of the WJ-III COG and SB5 with a sample of high achieving children. Individual confirmatory factor analyses were conducted using the WJ-III COG and SB5. Additionally. a joint confirmatory factor analysis was conducted using both the WJ-III COG and SB5. The results indicated an alternative six-factor WJ-IlI COG and four-factor SB5 models provided the best fit to the data of a high achieving sample, supporting previous research suggesting high achieving children display differences in cognitive constructs when compared with their average counterparts. The joint-confirmatory factor analysis indicated the best measures for the CHC factors measured by both the WJ-III COG and SB5 to help guide cross-battery assessments with high functioning children. Clinical applications of the findings are discussed. / Department of Educational Psychology

Significant evidence from the legislation, medical/clinical, or professional practice perspective all points to the advantages and necessity of conducting comprehensive assessment of cognitive abilities, especially in young children, to identify cognitive deficits, arrive at an accurate diagnosis, and establish bases for developing interventions and recommending services. Cross-battery assessment approach provides school psychologists a useful tool to strengthen their preferred cognitive battery by adopting and comparing subtests from other batteries to build up a comprehensive and theoretically sound evaluation of an individual’s cognitive profile to increase the validity of test interpretation. Using joint confirmatory factor analysis, this study explored the combined underlying construct validity of the Woodcock-Johnson Tests of Cognitive Abilities, Third Edition (WJ-III COG) and the Stanford-Binet Intelligence Scales, Fifth Edition (SB5) with an independent sample of preschool children. Seven models were examined and the results showed that relatively, the underlying construct of the two tests was best represented by a threestratum alternative CHC model in which the Gf factor and subtests had been removed. This indicates that not all the CHC constructs shared by both tests can be reliably identified among young children. Constructs of the CHC theory may be represented differently on preschool cognitive batteries due to developmental influences. Although WJ-III COG and SB5 tests as a whole did not demonstrate good results for purposes of cross-battery assessment, certain subtests (e.g., subtests representing crystallized intelligence) from each battery offer interpretative value for individual broad ability factors, providing school psychologists an in-depth understanding of a preschooler’s crystallized knowledge. Exploratory factor analyses were conducted with subtests from WJ-III COG and SB5 representing the four shared broad factors (Gc, Gf, Gv, and Gsm). Results revealed that a 4-factor solution is a better model fit to the data. Future research includes recruiting young children with disabilities or special needs to explore best representative underlying construct of combined WJ-III COG and SB5, allowing for cross-battery assessment. / Access to thesis permanently restricted to Ball State community only / Department of Educational Psychology

This study investigated the results of administering two intelligence tests, the Wechsler Intelligence Scale for Children -Third Edition (WISC-111), and the Stanford-Binet Intelligence Scale - Fourth Edition, to each of 33 Australian children with an intellectual disability. The experiment used a counterbalanced design in which the tests, order of presentation of the tests, the gender of the subjects, and the gender of the test administrators were factors. The 33 volunteer subjects, 14 males and 19 females, aged between 6 and 16 years, and known to have an intellectual disability, were allocated randomly for the assessments. The test administrators were students in the Clinical and Organisational Masters Program from the University of South Australia. It was hypothesised that; there would be a difference between the IQs on the two tests; that on average the WISC-111 FSIQ would be lower than the SB-1V TC; and that there would be a positive relationship between the WISC-111 FSIQ and the SB-1 V TC Statistical analysis of the data found the two tests' overall scores to be significantly different, while the counterbalanced factors and their interactions did not reach significance. There was a significant 4 point difference found between the mean WISC-111 FSIQs and SB-1V TCs. The results of a Pearson Product Moment Correlation Coefficient revealed a strong positive correlation (r = .83). between the WISC-111 FSIQ and SB-1V TC. This finding supported the concurrent validity of the tests in this special population sample. It was suggested that while the two tests measured similar theoretical constructs of intelligence, the two tests were not identical and therefore the results were not interchangeable. Variable patterns of results were found among subtest scores from the two tests, and the implications for field work discussed. The differences between raw WISC-111 FSIQ and SB-1V TC scores were calculated, and a z transformation was applied to the difference scores. The resulting difference distribution and cumulative percentages were then suggested as a reference table for practitioners. Studies that examined clerical errors in scoring intelligence test protocols were reviewed. The manually scored test protocols in this study were rescored using a computer scoring programme and 27 errors were found and corrected. From the results of the experiment several suggestions were made; that agencies using large numbers of intelligence tests, or which test the same child over time, should make a decision to use the same test, wherever possible, for comparison; that all intelligence test protocols be computer scored as a checking mechanism; and that all professional staff should be aware of the possible differences which can occur between intelligence scores, resulting from norming and other differences. / thesis (MSocSc)--University of South Australia, 1999.

This study proposed to evaluate the appropriateness of selected subtests of the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE) for use with severely to profoundly hearing impaired children. The subjects used in this study were enrolled in a residential/day school for the deaf whose educational methodology was Total Communication. The subjects were tested on both the SB:FE nonverbal selected subtests and the Performance Scale of the Wechsler Intelligence Scale for Children-Revised (WISC-R PIQ). To assess appropriateness, several procedures were employed comparing data gathered from the hearing impaired sample with data reported for the standardized population of the SB:FE. Correlations were computed between the WISC-R and the SB:FE and comparisons of the total composite scores for each measure were made to detect any systematic differences. The results indicated that the correlations reported for the hearing impaired sample are generally similar to the correlations reported for the standardized sample of the SB:FE. The analysis performed between the Area Scores of the SB:FE and the WISC-R PIQ to detect systematic differences revealed a difference of one standard deviation between these two instruments, with the. SB:FE results being lower than the WISC-R PIQ results. It was concluded that the selected subtests of the SB:FE and the WISC-R PIQ could not be used interchangeably. Further research into this area was advised before using this measure to estimate general cognitive ability for hearing impaired children whose levels of language development may be delayed. Further research was also encouraged to confirm the suggestion of greater predictive validity of the SB:FE with academic measures. It was suggested that these findings indicated that the use of language as a cognitive tool may be important in acquiring certain problem solving skills. / Education, Faculty of / Educational and Counselling Psychology, and Special Education (ECPS), Department of / Graduate

The purpose of this study was to compare the performance of children on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) with their performance on the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE). One hundred and four children between 3 and 7 years of age were administered both tests. A moderate correlation was found between the WPPSI-R Full Scale IQ and the SB:FE Composite Score with a Pearson product-moment correlation of .46. This correlation suggests that the two tests are not interchangeable measures of children's intelligence. They may measure different, equally important aspects of intelligence. As both tests used are relatively new, the current findings should be considered one step in the accumulation of knowledge about the usefulness of the WPPSI-R.

Study conducted with 63 rural school children, as measured by the Revised Stanford-Binet Intelligence Scale. Since size of vocabulary is considered to be a relatively valid measure of intelligence and correlates to a high degree with the mental age obtained on the Biney scale, it is concluded in accordance with the results of this study, that the test as a whole may be considered a valid measure of the mental ages of rural school children. However, since the cases used in this study were taken from a limited population, the results are not to be considered conclusive, but due to the high correlation obtained, a need for further study is indicated. / "A Paper." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Science." / "February, 1951." / Typescript. / Advisor: Marcus B.
