Basic criteria for determination of Attention Deficit Hyperactivity Disorder (ADHD) include hyperactivity, impulsivity, and distractibility. Four scales of the Personality Inventory for Children have been found to be useful in the diagnosis of ADHD. Impulsivity and distractibility can affect scores on the Hand Movements, Number Recall, Word Order, Spatial Memory, Arithmetic, Riddles, and Matrix Analogies subtests of the Kaufman Assessment Battery for Children. Subjects were 100 children, aged six through 13 who were referred for psychological assessment. The purpose of this study was to determine if there was a correlation between scores on the four scales of the PIC and the designated subtest scores on the KABC. Four correlations were significant, but of low magnitude.

This study investigated the relation of the Kaufman Assessment Battery for Children (K-ABC) with the Wechsler Intelligence Scale for Children - Revised (WISC-R) for learning disabled (LD) children, the relation of K-ABC Achievement subtests with other achievement tests, and the relation of verbal and perceptual abilities assessment and the K-ABC. One hundred white, middle to above socioeconomic status (SES), LD students 6 to 12 1/2 years old were administered the K-ABC in addition to the test battery used to identify them. Findings indicated significant differences (2<-01) between WISC-R Full Scale scores and KABC MPC scores, with MPC scores being 3.33 points lower. Significant correlations (2<-01) were found between the following: (a) WISC-R Performance scores and K-ABC Simultaneous scores, (b) K-ABC Sequential and Simultaneous scores, (c) WISC-R Performance and K-ABC Sequential scores, (d) K-ABC Arithmetic and WRAT Arithmetic, and (e) K-ABC Reading Understanding and the following: Woodcock Word Identification, Woodcock Passage Comprehension, WRAT Reading, and Durrell Silent Reading. The study found the MPC correlates higher with tests of perceptual ability than with tests of verbal ability. Results indicate the following: (a) the WISC-R and K-ABC can substitute each other when measuring overall intelligence, (b) the WISC-R and K-ABC do not measure the same abilities, (c) the Sequential-Simultaneous score discrepancy is a poor diagnostic indicator of LD, (d) the discrepancy between the Achievement scale and the K-ABC intelligence scales is a poor diagnostic indicator of LD, (e) the K-ABC Arithmetic subtest is no better and no worse than the WRAT Arithmetic subtest, (f) WRAT Reading, Woodcock Word Identification and K-ABC Reading Recognition are not interchangeable measures of word calling skills, (g) the K-ABC Reading Understanding subtest is as adequate a measure of reading comprehension as other available tests, (h) the MPC is clearly more a measure of perceptual ability than of verbal ability, and (i) the KABC is no more fair a measure to use with LD children than are intelligence tests with a heavy language component.

The purpose of this study was to investigate the relationship among the various scales of the Kaufman Assessment Battery for Children and the Wechsler Intelligence Scale for Children-Revised. Of particular interest was the degree to which the Wechsler Verbal and Performance IQ's contributed to the prediction of the K-ABC Mental Processing Composite and the K-ABC Achievement score respectively.The subjects were 51 students, aged 8-0 to 12-0, who had been referred for psychoeducational assessment because of suspected learning disabilities. They were evaluated with both the K-ABC and the WISC-R as part of a standard battery.Descriptive statistics and univariate correlations were computed. Multiple regression procedures revealed that significant relationships existed between the composite of predictor variables, the Wechsler Verbal and Performance IQ's, and the criterion variables, the K-ABC Mental Processing Composite and the K-ABC Achievement score when each was considered separately.Stepwise multiple regression procedures indicated that the unique contribution of the Wechsler Verbal IQ to the prediction of the K-ABC Mental Processing Composite was statistically significant. A significant relationship was not found, however, between the Performance IQ and the K-ABC Achievement score when the Verbal IQ had been statistically controlled.

The purpose of this study was to explore the construct validity of the Kaufman Assessment Battery for Children, Second Edition (KABC-II; Kaufman & Kaufman, 2004a) and the Woodcock-Johnson Tests of Cognitive Abilities, Third Edition (WJ-III COG; Woodcock, McGrew, & Mather, 2001) with a sample of 200 preschool children, ranging in age from 4 years, 0 months to 5 years, 1 1 months, and attending preschool and daycare programs in and around a Midwestern city. This study attempted to determine if the Cattell-Horn-Carroll (CHC) factor structure represented on these tests can be identified with young children. Individual confirmatory factor analyses were conducted separately with the KABC-II and WJ-III COG. Moreover, a joint confirmatory factor analysis was conducted using both the KABC-II and WJ-III COG. The results of the individual KABC-II factor analyses indicated a two-tiered Gf Gc model provided the best fit to the data, although the three-tiered CHC model also fit the data well. This suggests the underlying factor structure of the KABC-II is well represented by the CHC theory. The WJ-III COG was best represented by an alternative CHC model, in which the Gf factor and subtests had been removed, indicating not all CHC constructs represented on the WJ-III COG can be reliably identified among young children. The joint confirmatory factor analysis indicated the strongest measures of the shared CHC factors on the KABCII and WJ-III COG, which can help to guide cross-battery assessment with preschool children. Overall, the results confirmed multiple CHC abilities can be assessed with young children, implying clinicians should be using preschool tests that provide scores for several cognitive abilities. This study also revealed the constructs of the CHC theory may be represented somewhat differently on preschool tests due to developmental influences. Strong correlations were evident between unrelated tasks, primarily because the verbal and linguistic demands of many subtests caused them to load unexpectedly on the Gc factor. Suggestions for future research include conducting the same study using preschool children with suspected disabilities, as well as with older children, examining other instruments that include a Gf factor, and conducting exploratory factor analysis with subtests from the KABC-II and WJ-III COG that contain significant components of more than one ability. / Department of Educational Psychology

Individual differences in human intellectual abilities and the measurement of those differences have been of great interest to the field of school psychology. As such, different theoretical perspectives and corresponding test batteries have evolved over the years as a way to explain and measure these abilities. A growing interest in the field of school psychology has been to use more than one intelligence test in a "cross-battery" assessment in hopes of measuring a wider range (or a more in-depth but selective range) of cognitive abilities. Additionally, interest in assessing intelligence began to focus on preschool-aged children because of initiatives to intervene early with at-risk children. The purpose of this study was to examine the Stanford-Binet Intelligence Scales, Fifth Edition (SB-V) and Kaufman Assessment Battery for Children, Second Edition (KABC-II) in relation to the Cattell-Horn-Carroll (CHC) theory of intelligence using a population of 200 preschool children. Confirmatory factor analyses (CFAs) were conducted with these two tests individually as well as in conjunction with one another. Different variations of the CHC model were examined to determine which provided the best representation of the underlying CHC constructs measured by these tests. Results of the CFAs with the SBV revealed that it was best interpreted from a two-stratum model, although results with the KABC-II indicated that the three-stratum CHC model was the best overall design. Finally, results from the joint CFA did not provide support for a cross-battery assessment with these two particular tests.3 / Department of Educational Psychology

The Kaufman Assessment Battery for Children is a relatively new instrument designed to measure the cognitive abilities of children ages 2 1/2 to 12 1/2. The battery was predominantly based upon Luria's theory of cognitive processing which proposes a simultaneous and sequential dichotomy for the analysis of information. Exploratory and confirmatory factor analyses have generally supported this theory. However, across different age groups and with special populations, analyses have been inconsistent.Few alternative structures for the battery have been tested, especially with special populations.The purpose of the present study was to assess the viability of a two factor structure based upon the modality of input for a group of students referred for learning difficulties. One hundred and twelve students, ages 7 to 12 1/2, who had been referred by teachers because of learning difficulties were used in the study. The thirteen subtests of the K-ABC were specified as being associated with a visual input factor, an auditory input factor, or both. Confirmatory factor analysis, as performed by the LISREL VI computer program, was then used to test this hypothesis. Unreasonable parameter estimates led to the rejection of the model for this sample. This lack of confirmation is discussed in terms of high correlations among estimates, misspecification of the model, sample homogeneity, and lack of independence among the subtests in terms of input modality. It was concluded that input modality was not a major factor in performance on the battery for this particular sample.

The purpose of the present study was to determine if African American and Caucasian preschool children displayed similar patterns of performance among the Cattell-Horn-Carroll (CHC) factors measured by the Kaufman Assessment Battery for Children, Second Edition (KABC-II). Specifically, a profile analysis was conducted to determine if African Americans and Caucasians displayed the same patterns of highs and low and scored at the same level on the KABC-II composites and subtests. Forty-nine African American (mean age = 59.14 months) and 49 Caucasian (mean age = 59.39) preschool children from a Midwestern City were included in the study and were matched on age, sex, and level of parental education. Results of a profile analysis found African American and Caucasian preschool children had a similar pattern of highs and lows and performed at the same level on the CHC broad abilities as measured by the KABC-II. Comparison of the overall mean IQ indicated no significant differences between the two groups. The overall mean difference between groups was 1.47 points, the smallest gap seen in the literature. This finding was inconsistent with previous research indicating a one standard deviation difference in IQ between African Americans and Caucasians. A profile analysis of the KABC-II subtests found the African American and Caucasian groups performed at an overall similar level, but did not show the same pattern of highs and lows. Specifically, Caucasians scored significantly higher than African Americans on the Expressive Vocabulary subtest which measures the CHC narrow ability of Lexical Knowledge. Results of this study supported the KABC-II’s authors’ recommendation to make interpretations at the composite level. When developing hypotheses of an individual’s strengths and weaknesses in narrow abilities, clinicians should be cautious when interpreting the Expressive Vocabulary subtest with African Americans. Overall, results of this study supported the use of the KABC-II with African American preschool children. When making assessment decisions, clinicians can be more confident in an unbiased assessment with the KABC-II. Future research could further explore the CHC narrow abilities in ethnically diverse populations. Additionally, more research should be conducted with other measures of cognitive ability designed to adhere to the CHC theory, and the appropriateness of those tests with an African American population. Furthermore, future research with the KABC-II could determine if the results of the present study were replicated in other age groups. / Department of Educational Psychology

La nostra investigació s'inscriu en la concepció dinàmica de la intel·ligència, i concretament en el processos que configuren el processament cerebral en el Model d'integració de la informació descrit per Das, Kirby i Jarman (1979). Els dos processos cerebrals que constitueixen la base de la conducta intel·ligent són el processament simultani i el processament seqüencial; són les dues estratègies principals del processament de la informació. Tota classe d'estímul és susceptible d'ésser processat o bé seqüencialment (seriació, verbal, anàlisi), o be simultàniament (global, visual, síntesi).Basant-nos en el recull bibliogràfic i amb la convicció de que apropant-nos al coneixement de les peculiaritats del processament de la informació, ens endinsem en la comprensió del procés que mena a la conducta intel·ligent, i per tant, a l'aprenentatge, formulem la següent hipòtesi de treball: en els nens de preescolar (d'entre els 3 i els sis anys) es donaran aquest dos tipus de processament i variaran en funció de l'edat, el sexe, l'atenció, les dificultats d'aprenentatge, els problemes de llenguatge, el bilingüisme, el nivell sociocultural, la dominància manual, el nivell mental i de la presència de patologia. Les diferències que s'esdevinguin ens permetran de formular criteris i pautes per a la intervenció educativa.Els nostres objectius es refonen en mesurar el processament en nens de preescolar de les comarques gironines, verificar la relació de cada tipus de processament amb les variables esmentades, comprovar si s'estableix un paral·lelisme entre el processament i les aportacions de concepció localitzacionista de les funcions cerebrals en base als nostres resultats, i pautes per a la intervenció pedagògica.Quant al mètode, hem seleccionat una mostra representativa dels nens i nenes matriculats a les escoles publiques de les comarques gironines durant el curs 92/93, mitjançant un mostreig aleatori estratificat i per conglomerats. El tamany real de la mostra és de dos-cents seixanta un subjectes.Els instruments emprats han estat els següents: el Test K-ABC de Kaufman & Kaufman (1983) per a la avaluació del processament; un formulari dirigit als pares per a la recollida de la informació pertinent; entrevistes amb les mestres, i el Test de la Figura Humana de Goodenough.Pel que fa referència als resultats de la nostra recerca i en funció dels objectius proposats, constatem els fets següents. En els nens de preescolar, amb edats d'entre els tres i els sis anys, es constata l'existència dels dos tipus de processament cerebral, sense que es doni un predomini d'un sobre de l'altre; ambdós processaments actuen interrelacionadament.Ambdós tipus de processament milloren a mesura que augmenta l'edat, però es constaten diferències derivades del nivell mental: amb un nivell mental normal s'hi associa una millora d'ambdós processaments, mentre que amb un nivell mental deficient només millora fonamentalment el processament seqüencial.Tanmateix, el processament simultani està més relacionat amb les funcions cognitives complexes i és més nivell mental dependent que el processament seqüencial.Tant les dificultats d'aprenentatge com els problemes de llenguatge predominen en els nens i nenes amb un desequilibri significatiu entre ambdós tipus de processament; les dificultats d'aprenentatge estan més relacionades amb una deficiència del processament simultani, mentre que els problemes de llenguatge es relacionen més amb una deficiència en el processament seqüencial.Els nivells socioculturals baixos es relacionen amb resultats inferiors en ambdós tipus de processament.Per altra part, entre els nens bilingües és més freqüent el processament seqüencial significatiu.El test de la Figura Humana es comporta com un marcador de processament simultani i el nivell atencional com un marcador de la gravetat del problema que afecta al processament i en el següent ordre: nivell mental deficient, dificultats, d'aprenentatge i problemes de llenguatge . Les deficiències atencionals van lligades a deficiències en el processament simultani i a la presencia de patologia.Quant a la dominància manual no es constaten diferències en el processament.Finalment, respecte del sexe només podem aportar que quan un dels dos tipus de processament és deficitari,i es dóna per tant, un desequilibri en el processament, predomina significativament el nombre de nens afectats per sobre del de nenes. / This issue was designed to study cerebral processing as an application of the successive-simultaneous processing model (Das, Kirby and Jarman 1979) in children of our country.The relationship between K-ABC simultaneous and successive scores and several conditions as well as the relationship between these conditions and qualitative variables was investigated. Also, Goodenough test was added to the study as a complement. Age, sex, attention, learning difficulties, speech problems, bilingualism, sociocultural level, hand dominance, IQ, are conditions considered in the research. The objectives of the study were to provide conclusions for applicability to learning disabled children and, this way, to assist school teachers in an attempt to ameliorate educational system.Subject SampleRandom sampling of preschool children living in Girona, region of Catalonia (Spain) was selected for the study. The children ranged in age from 36 to 72 months with a mean age of 61 months (SD-8.07). Students (preschool children) participating in the present study were members of two classrooms, grade 1 (P4) and grade 2 (P5). Two strata were done based on the mode of classroom so sample was representative. Given that children population in Girona region is 7095 we were able to calculate sampling in terms of 262 subjects with proportion factor of 3.702 for each stratum. A peculiarity must be mentioned. Catalonia in Spain has two languages, Catalan and Spanish languages but Catalan immersion is carried out in every school in Catalonia.InstrumentsTen subtests of the Kaufman Assessment Battery for Children (Kaufnan & Kaufman,1983) were selected for the present study. Seven simultaneous tests were applied: Gestalt Clousure, Triangles, Matrix Analogies, spatial Memory, Photo Series, Magic Window, Face Recognition. According to age, each child took different number of subtests. Three successive tests were administrated: Number Recall, Word Order, Hand Movements. For complete descriptions of tasks refer to Kaufman & Kaufman manual (1983). Also, the analysis reported by Das (1984) hasbeen considered. In addition to these, the Goodenough test (Harris,1982) was applied as instrument for assessing intellectual stage of development . On the other hand, a questionnaire was done.ProcedureParents' permission was sought prior to assessing the children, and in no case were we denied permission. Subjects were tested individually. Testing was carried out in a quiet room at the school. The average time per assessment was 35 minutes. All the testing was conducted in the school by the same author.Data AnalysisThe SPSS program was used to analyze the data. The Pearson Product-Moment Correlation Coefficient was used to describe a relationship between two variables. The t-Student was used to test the significance of differences between means. Chi-Square (x2) test was used to test the significance of differences between proportions. Mantel-Haenszel test was also applied where indicated for determining whether two variables were dependent or independent.Results and conclusionsThe following statements were concluded: (1) Both cognitive processes, successive and simultaneous, were present in the range of 3-6-year-old. No one of the two modes of processing was significantly superior. Both of them work interrelated. (2) Scores are higher with increasing age in successive and simultaneous processing but in the case of the retarded subjects that is true for the successive but not for the simultaneous. (3) Simultaneous processing is more related to complex cognitive functions than successive processing. (4) Learning difficulties and speech problems are more frequent in the case of imbalanced processing. Learning disability is more frequently related to simultaneous processing but speech problems to successive processing. (5) Lower sociocultural children score worse in both cognitive processing. (6) Bilingual children are more frequently successive in the cognitive processing. (7) No differences with respect to hand dominance were found. (8) When one of the two cognitive processing is deficient (imbalanced processing) the number of boys is significantly superior to the number of girls.
