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.  相似文献

This study examined the concurrent validity of the General Ability Measure for Adults (GAMA1; Naglieri & Bardos, 1997) and the Wechsler Adult Intelligence Scale‐Third Edition (WAIS‐III; Wechsler, 1997). Sixty college students were administered both instruments in counterbalanced order. A comparison of the mean scores on the GAMA and WAIS‐III indicated that the sample obtained similar GAMA and WAIS‐III PIQ scores. In contrast, the sample's mean GAMA IQ score was significantly lower than the sample's mean FSIQ and VIQ scores. Although the GAMA IQ score was positively correlated with all WAIS‐III IQ and Index scores, this new instrument was more clearly associated with visual‐spatial reasoning, as defined by the WAIS‐III PIQ. The GAMA's accuracy in predicting performance on the WAIS‐III FSIQ and PIQ also was examined, with the GAMA underestimating WAIS‐III FSIQ and PIQ scores for participants falling within the Superior and Very Superior range of intellectual functioning. © 2001 John Wiley & Sons, Inc.  相似文献

The concurrent validity between the Woodcock-Johnson Psycho-Educational Battery-Revised Tests of Cognitive Ability (WJ-R, COG) (Early Development) and the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) was examined. These two measures were administered in two separate sessions in counterbalanced order to 30 normal 3-, 4-, and 5-year-old subjects from the Midwest. Findings suggested that the WJ-R Broad Cognitive Ability (BCA) and the WPPSI-R Full Scale IQ (FSIQ) and Verbal IQ (VIQ) were significantly correlated, but that the mean BCA scores on the WJ-R (COG) were significantly below the mean FSIQ scores on the WPPSI-R by only - 4.50 standard score points. No age or sex differences were found on either the WJ-R (COG) or the WPPSI-R. Significant correlations were found between the WJ-R (COG) BCA and the following WJ-R (COG) Broad Ability Factor scores: Long-Term Retrieval, Short-Term Memory, Auditory Processing, and one test called Picture Vocabulary representing comprehension-knowledge. A significant correlation was also found between the WPPSI-R Performance IQ (PIQ) and the WJ-R (COG) Visual Processing cluster. Findings are discussed in terms of the theories of intelligence underlying each test. Implications for assessment of preschoolers under PL 99–457 also are discussed.  相似文献

The interpretation of cognitive test scores often leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Therefore, it is important that practitioners administer and score cognitive tests without error. This study assesses the frequency and types of examiner errors that occur during the administration and scoring of the Woodcock‐Johnson III Tests of Cognitive Abilities (WJ III COG). Data from 36 graduate students across 108 test records revealed a total of 500 errors across all records. Further analyses indicated three frequently occurring errors, including the use of incorrect ceilings, failure to record errors, and failure to encircle the correct row for the total number correct. The results of this study may be used to inform training programs so that appropriate steps can be taken to decrease the number of examiner errors on the WJ III COG and similar cognitive test batteries. © 2009 Wiley Periodicals, Inc.  相似文献

The Dumont‐Faro short form was used to estimate Wechsler Intelligence Scales for Children‐III (WISC‐III) Full Scale IQ scores for 45 special education students in a rural setting. Using the validation criteria proposed by Resnick and Entin (1971), results demonstrated that IQ scores generated by the Dumont‐Faro short form were positively correlated (r= .96) with the WISC‐III Full Scale scores. A significant mean difference in scores and an IQ misclassification rate of 44%, however, challenge the utility of the Dumont‐Faro short form for estimating WISC‐III Full Scale IQ. © 2001 John Wiley & Sons, Inc.  相似文献

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.  相似文献

This study examined the concurrent validity of the Slosson Full‐Range Intelligence Test (S‐FRIT) by comparing S‐FRIT scores to the scores of the Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Woodcock‐Johnson Tests of Achievement–Revised (WJ‐R). Data from 123 elementary students' screening and psychological testing results were examined. Results revealed that the S‐FRIT scores were more related to overall intelligence, verbal, and math abilities than nonverbal intelligence, reading, or written language abilities. Further, it was found that 89% of the participants' S‐FRIT Full‐Range IQ scores fell within one standard deviation of their WISC‐III FSIQ scores, with an average discrepancy of 7.6 points. Discrepancies between S‐FRIT and WISC‐III scores were also examined by educational diagnostic categories and ability levels. Limitations and suggestions for future research are provided. © 2002 John Wiley & Sons, Inc.  相似文献

As part of a mandated three-year reevaluation, the Differential Ability Scales (DAS) was administered to 53 children identified as having a learning disability approximately 3 years after each had been administered the Wechsler Intelligence Scale for Children—Third Edition (WISC-III). The DAS's General Conceptual Ability score (GCA), and Verbal and Spatial Cluster scores were nonsignificantly different from the WISC-III's Full Scale, Verbal, and Performance scores. The Nonverbal Reasoning score of the DAS (a measure of Fluid intelligence not assessed by the WISC-III) was significantly different from both the Verbal and Performance scores. High correlations were found between the similar constructs on the two tests. Approximately 96% of the students obtaining a certain classification from the WISC-III obtained a comparable classification from the DAS. © 1996 John Wiley & Sons, Inc.  相似文献

This paper examined the diagnostic utility of subtest variability, as represented by the number of subtests that deviate from examinees' mean IQ scores, for identifying students with a learning disability (LD). Participants consisted of the 2,200 students in the WISC‐III normative sample and 684 students (Mdngrade = 5; Mage = 10.8) identified as LD. The number of subtests deviating from examinees' Verbal, Performance, and Full Scale IQ by ±3 points for normative and exceptional samples were contrasted via Receiver Operating Curve (ROC) analyses. Results indicated that LD students did not differ from normative sample children at levels above chance. It was concluded that deviation of individual subtest scores from mean IQ scores has no diagnostic utility for hypothesizing about students with learning disabilities. © 2000 John Wiley & Sons, Inc.  相似文献

This study examined the relative contributions of measures of Cattell‐Horn‐Carroll (CHC) cognitive abilities in explaining writing achievement. Drawing from samples that covered the age range of 7 to 18 years, simultaneous multiple regression was used to regress scores from the Woodcock‐Johnson III (WJ III; Woodcock, McGrew, & Mather, 2001) that represent CHC broad and narrow abilities onto the WJ III Basic Writing Skills and Written Expression cluster scores. At most age levels, Comprehension‐Knowledge demonstrated moderate to strong effects on both writing clusters, Processing Speed demonstrated moderate effects on Basic Writing Skills and moderate to strong effects on Written Expression, and Short‐Term Memory demonstrated moderate effects. At the youngest age levels, Long‐Term Retrieval demonstrated moderate to strong effects on Basic Writing Skills and moderate effects on Written Expression. Auditory Processing, and Phonemic Awareness demonstrated moderate effects on only Written Expression at the youngest age levels and at some of the oldest age levels. Fluid Reasoning demonstrated moderate effects on both writing clusters only during some of the oldest age levels. Visual‐Spatial Thinking primarily demonstrated negligible effects. The results provide insights into the cognitive abilities most important for understanding the writing skills of children during the school‐age years. © 2008 Wiley Periodicals, Inc.  相似文献

The Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Stanford‐Binet Intelligence Scale–Fourth Edition (SB‐IV), were administered to 20 gifted children and 20 non‐gifted children to examine the extent of the difference in IQ scores obtained on the two tests and whether order effects were present. Results show that the SB‐IV Composite Score was significantly higher than the WISC‐III Full Scale IQ for both groups. However, for the gifted group, unlike the non‐gifted group, this difference achieved significance only when the SB‐IV was administered first. When either IQ test was administered to the gifted students for the first time, without the confound of a learning influence, there was no significant difference in mean scores. However, when both tests were administered, it was found that the SB‐IV influenced the WISC‐III Full Scale IQ in a downward direction whereas the WISC‐III influenced the SB‐IV Composite Score in an upward direction. © 2002 Wiley Periodicals, Inc.  相似文献

This study examined the underlying constructs measured by the Differential Ability Scales (DAS; C.D. Elliott, 1990a) as they relate to the Cattell‐Horn‐Carroll (CHC) Theory (K.S. McGrew, 1997) of cognitive abilities. The DAS and Woodcock‐Johnson Tests of Cognitive Abilities (WJ‐III COG; R.W. Woodcock, K.S. McGrew, & N. Mather, 2001) were administered to 131 children in grades 3 through 5 who took part in a concurrent validity study included in the Woodcock‐Johnson Tests of Cognitive Abilities, Third Edition, technical manual (K.S. McGrew & R.W. Woodcock, 2001). Confirmatory factor analyses using maximum likelihood estimation were conducted with the AMOS 5.0 (J.L. Arbuckle, 2001) statistical program to evaluate three models of increasing complexity, to compare how well each fit the data set, and to identify the one that best described the underlying constructs measured by the DAS. Results suggested that the synthesized Three‐Stratum CHC Model provided the most parsimonious representation among the three models tested. © 2007 Wiley Periodicals, Inc.

A comparison of the visual and auditory processing factors of the WJR Tests of Cognitive Ability and the visual and auditory memory factors of the Learning Efficiency Test, II were examined for 120 undergraduate college students. Repeated measures ANOVAs revealed two significant performance differences: between the WJR COG and LET-II visual processing factors and between the WJR Broad Cognitive Ability index and the LET Global Memory score. Although there was no significant performance difference on the WJR COG and LET-II auditory processing factors, the two measures were independent, accounting for less than 4% shared variance. Similarly, WJR COG and LET-II visual processing factors also were independent. It was hypothesized that differing levels of task complexity, such as order vs. unordered memory retrieval requirements, semantic meaningfulness of the material presented, and rehearsal and/or presence of verbal interference components, represent distinct performance outcome measures of visual and auditory processing by the WJR COG and LET-II. © 1997 John Wiley & Sons, Inc.  相似文献

In this article, we report the findings of an exploratory empirical study that investigated the relationship between English Language Proficiency (ELP) on performance on the Woodcock‐Johnson Tests of Cognitive Abilities‐Third Edition (WJ III) when administered in English to bilingual students of varying levels of ELP. Sixty‐one second‐grade students, identified as Limited English Proficient, were recruited from a suburban public school district and were given the WJ III in addition to their annual state standardized assessment of ELP. The findings of this study provide evidence to support a linear, inverse relationship between ELP and performance on tests that require higher levels of English language development and mainstream cultural knowledge. The implications of the findings of the present study suggest that practitioners must consider an examinee's level of developmental language proficiency and cultural knowledge acquisition as continuous variables when determining the impact of such factors on test performance and evaluation regarding whether scores obtained from tests administered in English are indeed valid for interpretation.  相似文献

This study examined the predictive utility of five formative reading measures: words correct per minute, number of comprehension questions correct, reading comprehension rate, number of maze correct responses, and maze accurate response rate (MARR). Broad Reading cluster scores obtained via the Woodcock–Johnson III (WJ III) Tests of Achievement served as the criterion variable. Examiners administered all reading measures to 98 students enrolled in upper elementary (UES) and middle school (MS) grades (grades 4 through 8). Results indicated significant intercorrelations within all predictor variables for the combined and UES samples; fewer intercorrelations existed at the MS level. MARR exhibited the highest correlation with WJ III Broad Reading across all correlational analyses. Additional regression analyses indicated that the MARR technique best predicted WJ III Broad Reading cluster scores across all groups analyzed. Limitations of the current study and suggestions for future research are discussed.  相似文献

The relationship between the Early Screening Profiles (ESP; Harrison, 1990) and the Differential Ability Scales (DAS; Elliott, 1990a) was studied. The participants were 94 (57 males, 37 females) at‐risk preschoolers ranging in age from 3 years 6 months to 5 years 11 months (M= 4 years 7 months; SD= 6.3 months). The sample included 72 Caucasians, 21 African Americans, and one Hispanic. This study found that the DAS GCA (General Conceptual Ability) mean score was significantly lower than the ESP Total Screening mean score. However, a strong relationship (r= .78) was found between the ESP Total Screening and DAS GCA scores, indicating that the ESP is a good predictor of cognitive ability among at‐risk preschoolers. © 2000 John Wiley & Sons, Inc.  相似文献

Reviews involving the Wechsler Scales for children suggest that Full Scale IQ scores on the Wechsler Intelligence Scale for Children, Third Edition, average 5 to 6 points lower than scores on the second edition of the scale [WISC‐R, Wechsler, D. (1974). Zimmerman & Woo‐Sam, 1997], with the differences distributed disproportionately over subtests, i.e., with larger discrepancies found within the Performance Scale (Wechsler, 1991). Changes on the revised subtests of the WISC‐III Performance Scale may place children with ADHD at a disadvantage compared to their performance on analogous WISC‐R subtests. We examined IQ test performance in 122 unmedicated children with ADHD (61 given the WISC‐R, 61 given the WISC‐III), and 46 children from a healthy, comparison group (23 given the WISC‐R, 23 given the WISC‐III). The ADHD and comparison group samples were matched for sex and for Verbal IQ between WISC‐R and WISC‐III. Children with ADHD had significantly lower Performance IQ on WISC‐III compared to the WISC‐R, with the Picture Arrangement subtest showing the most significant difference. In contrast, there were no significant differences between the WISC‐R and WISC‐III cohorts on Performance IQ or any Performance subtests among the comparison group. These findings highlight the importance of examining the comparability of ability test revisions among clinical and non‐clinical populations, and will be especially salient when the WISC‐III is revised. © 2003 Wiley Periodicals, Inc.

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.  相似文献

This is a normative study to investigate the transferability of norms from western-based intelligence tests to Filipino students. More than 2,700 Filipino sixth graders were sampled across the country and administered the Naglieri Nonverbal Ability Test (NNAT). Scores were then compared to the US normative sample. The results showed no significant differences in mean scores and the standardized mean difference is small when scaled scores are used in comparison. However, in situations where the test needs to be used for specific portions of the population such as in the context of gifted education, further analysis revealed that the distribution of scores for the Philippine sample differed significantly from the expected values based on the US norms, particularly in the tail ends of the distribution. In these cases, it may not be valid to transfer the US norms directly to Filipino students without any modification.  相似文献

This study examined the reliability and validity of scores on a fluency‐based measure of reading comprehension. The Dynamic Indicators of Basic Early Literacy Skills (DIBELS; 6th ed. revised) Retell Fluency (RTF), Oral Reading Fluency (DORF), and Woodcock Johnson III NU Tests of Achievement (WJ‐III NU ACH) Reading Comprehension measures were administered to fourth‐grade students. Results indicated a large difference between real time and recorded retell fluency scores for each passage. In addition, students' retell fluency scores had a low correlation with their reading comprehension scores. In light of these findings, practitioners may want to exercise caution in using fluency‐based story‐retell scores as a measure of reading comprehension. © 2011 Wiley Periodicals, Inc.  相似文献
