Comparison of the SIT with the WISC-R for gifted students

There has been a need to identify a quick screening and reevaluation instrument to determine eligibility status for specialized programs. The Slosson Intelligence Test (SIT) is one instrument that has been suggested for this purpose. In a ten-year review of validity studies with the SIT, Stewart and Jones (1976) found substantial correlations between the SIT and WISC. They recommended that future validity studies with the SIT focus on specific subgroups with restricted IQ ranges. The present study compared the SIT with the WISC-R for a group of intellectually gifted students. The results indicated reduced correlations between the measures. The calculated regression equation was dissimilar to the one reported by Stewart and Jones for nonrestricted IQ populations, although predictive ability was greater. The need for comparing the SIT with other measures for specific subgroups was supported.     

A short form of the WISC-R for gifted students

Much effort has been devoted to the derivation of short forms of intelligence tests. The present study was undertaken to develop a short form of the WISC-R for the intellectually gifted. The results confirmed previous findings that the Vocabulary and Block Design dyad comprise the best two-subtest short form. The present study indicated that the Similarities, Vocabulary, Block Design, and Object Assembly tetrad could be the most useful in time and reliability.     

Comparison of personality profiles for intellectually gifted students and students outstanding in the fine and performing arts attending self-contained secondary schools

The study included 199 intellectually gifted students and 176 students in the fine and performing arts who were administered the High School Personality Questionnaire. The results indicated that the gifted students obtained higher Leadership Potential scores, while the talented students scored higher in Creativity. Several significant differences were found in the personality profiles of the two groups.     

A longitudinal study of the Stanford-Binet and WISC-R with special education students

A group of 95 black and 52 white low socioeconimic children assigned to special education calsses were initially given the Stanford-Binet (1972 norms) and three years later the WISC-R. Correlations between the Stanford-Binet and WISC-R Full Scale IQs were significant in both ethnic groups, with r=.60 for the total group. Correlations between the Stanford-Binet and WISC-R subtests also were generally signiificant (rs between .29 and .52 for the total group). Stanford-Binet and WISC-R Full Scale IQs did not differ significantly. For this sample of special education children, the Stanford-Binet was found to have satisfactory predictive validity.     

A study of self-actualization and self-concept in intellectually gifted students

The self-actualization and self-concept of 368 intellectually gifted students in grades 4 through 12 from a rural school district in a southern state were investigated using the Reflections of Self by Youth (ROSY; Schatz & Buckmaster, 1981), the Maslowian Scale (Falk, Bard, Duffy, Grieco, & Markus, 1988), and the Piers-Harris Children's Self-Concept Scale (Piers & Harris, 1969). School level and gender had significant effects on the ROSY. The mean for students at the high school level was higher than at either the elementary or junior high school level. The mean for girls was higher than for boys. A significant interaction between school level and gender was observed only on the Psychological subscale of the Maslowian Scale. The ROSY and Self-actualization subscale and Total score of the Maslowian Scale were significantly related to the Piers-Harris. The ROSY and the Maslowian Scale were found to share a significant relationship (r = .51).     

The development of cutoff scores on a WISC-R in the multidimensional assessment of gifted children

The summed scores of the WISC-R dyad, Vocabulary and Block Design, were cross-tabulated with full scale WISC-R scores for 249 children referred to a gifted program. The initial results indicated that the Vocabulary-Block Design dyad could be a useful tool in predicting full scale IQ for some children and thus leave time available for other types of assessment of students.     

A longitudinal comparison of WISC-III and WISC-R scores of special education students

This study investigated the performance of 166 special education students who had been administered the WISC-R and approximately 3 years later the WISC-III. The sample ranged in age from 6.0 to 16.6 years. The scores were analyzed using Pearson product moment correlation coefficients and t tests of the differences between means for related samples. The results indicated that there was a significant, positive correlation among global scales (p < .001). This finding suggests that the WISC-R and the WISC-III IQ scores measure similar abilities. Analysis of mean IQ score differences revealed significant differences in the WISC-R and the WISC-III IQ scores, with the WISC-III global scores being lower. Implications for the evaluation of students for special education are discussed, with special emphasis on the role and function of the psychologist practicing in the schools. © 1996 John Wiley & Sons, Inc.     

Validation of the Stanford-Binet Intelligence Scale: Fourth edition with exceptional black male students

Standard Age Scores on the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) and WISC-R IQs of 51 urban black males receiving special education services were compared. Correlations between the SBIV Composite scores and WISC-R Verbal, Performance, and Full Scale IQs were 0.803, 0.826, and 0.87 respectively. Correlations between all combinations of scales ranged from 0.612 to 0.888, median r=.723. SBIV Composite mean scores did not differ significantly from the mean WISC-R Full Scale, Verbal, and Performance IQs. Regression analysis of the three subgroups (BD. LD, and EMR) indicated that the SBIV possesses differential validity for each group. Tabular comparison of precision of classification between the SBIV and the WISC-R yielded a 78% agreement. These data suggest that the SBIV possesses utility for assessing the intelligence of black students classified as BD and EMR. However, the use of the scale with LD students is unsupported.     

Concurrent validity of the Stanford-Binet: Fourth edition and Kaufman assessment battery for children with learning-disabled students

This study examined the concurrent validity of the composite and area scores of the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) and the Mental Processing Composite and global scale scores of the Kaufman Assessment Battery for Children (K-ABC). The tenability of interpreting the SBIV using the fluid/crystallized model, as suggested by the authors, was also considered. The subjects were 30 Black, learning-disabled elementary school students. Results of a t test indicated that the Mental Processing Composite score of the K-ABC was significantly higher than the SBIV Composite score. Moderate to high correlations were obtained when SBIV composite and area scores were compared to K-ABC composite and scale scores, reflecting a positive relationship between the two tests. The measures of fluid abilities (K-ABC Composite score; SBIV Abstract/Visual Reasoning) were highly correlated. The results of a multiple regression analysis indicated a moderate degree of correlation among the measures of crystallized ability (K-ABC Achievement; SBIV Verbal Reasoning and Quantitative Reasoning). The findings of this study demonstrated adequate concurrent validity for the SBIV. In addition, the results provided limited support for describing test results utilizing the fluid/crystallized interpretation model. Further research is suggested in order to examine other validity issues, such as classification of special education students and the SBIV's relationship to other similar instruments.     

Comparison of the WISC-R and PPVT for a group of mentally retarded students

This study compared the WISC-R and PPVT scores for a group of 65 students classified as mentally retarded, ranging in age from 7.5 to 14.5. Pearson product moments (r) and correlated t values were employed in the analysis of data. The evidence from the present study indicated that for this sample of mildly retarded children and youth, the PPVT IQ score is significantly higher than the Full Scale IQ from the WISC-R. The current findings indicate that the same general pattern exists for the WISC-R and PPVT as for the WISC and PPVT scores.     

Investigation of the WISC-R for use with retarded children: Correlation with the 1972 Stanford-Binet and comparison of WISC and WISC-R profiles

A group of 80 mentally retarded youngsters, aged 6 to 16, was tested on the WISC-R, primarily to assess the continuity of measurement between the old and new WISCs. The WISC-R IQs correlated .65 to .82 with Stanford-Binet IQ for a subsample of 45 children, resembling the coefficients between the 1949 WISC and the Binet for retarded groups. In addition, the WISC-R test profiles for the 80 children corresponded closely to the WISC test profiles for many retarded samples. Thus, there was evidence to support the continuity of the WISC-R with its predecessor for retarded populations.     

Enriched education promotes the attentional performance of intellectually gifted children

The education of gifted children is of considerable interest. The present study focused on the effect of enriched education on intellectually gifted children’s attention. In the present study, 7–12-year-old children completed seven tests of attention (alertness, focused attention, divided attention, attentional switching, sustained attention, spatial attention, and supervisory attention) to investigate the differences among intellectually gifted children under different educational environments. The results showed that intellectually gifted children who received enriched education had better attentional performance than did intellectually gifted children who received standard education. The result affords theoretical support for gifted-education practice.     

Stability of WISC-R intelligence scores: Implications for 3-year reevaluations of learning disabled students

Student records of 170 learning disabled students from two area agencies were examined to determine the stability of WISC-R test scores administered as part of the 3-year reevaluation of students required by Public Law 94–142. The WISC-R had been readministered to 150 of these students. Stability coefficients were .72, .70, and .74 for the Verbal, Performance, and Full Scale IQ scores. Changes in Full Scale scores were 4 points or less for 52% of the sample. Changes greater than 15 points were noted for 4% of the sample. Results suggest that WISC-R scores are reasonably stable over a 3-year interval, and routine readministration of the WISC-R should not be required or encouraged.     

Comparison of the slosson intelligence test,revised norms,and WISC-R for children with learning problems and for gifted children

The Slosson Intelligence Test (revised norms) (SIT) and the WISC-R were compared in two samples of children. In the first sample, there were 34 black and 27 white rural Southeastern Alabama children being considered for special education classes. In the second sample, there were 4 black and 81 white suburban Alabama children being considered for classes for the talented and gifted. In both samples, correlations between the SIT IQ and WISC-R Full Scale IQ were significant (rs of .70 and .48, respectively). However, in the special education sample, SIT IQs were significantly higher than WISC-R Full Scale IQs by about 7 points. The results from both samples provide a moderate degree of support for the concurrent validity of the revised SIT norms, using the WISC-R as the criterion. However, the IQs on the two tests may not be interchangeable.     

Comparison of interrater reliability on the torrance tests of creative thinking for gifted and nongifted students

Despite their widespread use in identifying and evaluating programs for gifted and talented students, the Torrance Tests of Creative Thinking were standardized on samples that excluded gifted children. The interrater reliability of measures like the TTCT has been questioned repeatedly, yet studies with average students have demonstrated high interrater reliability. This study compares the interrater reliability of the TTCT for groups of gifted and nongifted elementary-school-aged students. Results indicated most interrater reliability coefficients exceeding .90 for both gifted and nongifted groups. However, multivariate analysis of variance indicated significant mean differences across the three self-trained raters for both gifted and nongifted groups. Consequently, use of a single scorer to evaluate TTCT protocols is recommended, especially where specific cutoff scores are used to select students.     

Comparison of the PPVT-R and WISC-R with urban educable mentally retarded students

Comparisons of the revised PPVT (PPVT-R) and the WISC-R were made with 67 EMR students. Significant differences were found between the PPVT-R mean standard scores and Verbal, Performance, and Full Scale IQs. The PPVT-R did not correlate significantly with the WISC-R scales or subtests, suggesting the tests are measuring different abilities.     

Attitudes toward science and science knowledge of intellectually gifted and average students in third,seventh, and eleventh grades

A questionnaire regarding attitudes toward science and scientific knowledge (Yager & Yager, 1985b) was administered to 143 intellectually gifted (IQ > 130) and intellectually average third-, seventh-, and eleventh-grade students. Measures of internal reliability on four attitude subscales and a content knowledge subscale are reported. Three-way ANOVAs comparing grade, sex, and ability revealed significant differences between average and gifted students in attitudes toward being a scientist, usefulness of science, and, as might be expected, in knowledge of science. Similarly, there were significant differences between grades on attitudes toward teachers and toward science classes, with the most favorable attitudes expressed in third grade, next most favorable in eleventh grade, and clearly more negative attitudes expressed by students in seventh grade. There also was a significant interaction between grade level and ability regarding attitudes toward science classes. In contrast to what might be expected from reported differences between males and females in attitudes toward science, gender as a separate variable did not have a significant main effect in any of the comparisons.     

Cognitive processes underlying WISC-R performance of gifted and learning disabled navajos

The purpose of this study was to provide an empirical basis for the interpretation of the WISC-R performance of Navajo children according to the Luria-Das Model of Simultaneous and Successive cognitive processes. Two groups of Native American Navajo subjects, 45 learning disabled and 41 gifted, were given the WISC-R. The scores on those subtests expected to involve Successive and Simultaneous processes were factor analyzed for each group and two factors were extracted. The factors, essentially similar for both samples, were interpreted to reflect the Successive and the Simultaneous modes of processing information as suggested by the Luria-Das Model. The gifted and learning disabled children had disparate loadings for some of the subtests, suggesting that the two groups may be using distinct modes of coding information.     

Matched pair comparison of WISC and WISC-R scores

Both the WISC and the WISC-R were administered to 54 children, with one half taking the WISC first and the other 27 taking the WISC-R first. Differences between mean subtest scaled scores and mean IQs were found to be influenced by the sequence of the tests, although all mean scores were higher on the second test when the WISC-R was given first. Data were presented suggesting the WISC-R given first tends to raise WISC scores, and WISC given first yields scores on the WISC-R which are essentially similar, effectively counsteracting the more “difficult” scoring for the WISC-R.     

A comparison of the Kaufman Assessment Battery for Children and the Stanford-Binet IV for the assessment of gifted children

The K-ABC and the Stanford-Binet IV (abbreviated test battery) were administered in a counterbalanced order to 32 gifted third- and fourth-grade students. It was found that the Stanford-Binet IV produced scores that were an average of eight points higher than those on the K-ABC. The concurrent validity coefficient of .70 indicated a high degree of association between test performance on these two tests. When the diagnostic heuristic of +2 SDs is used to identify gifted children, 68.6% concordance was found between these tests. Eighty percent of the discordance involved cases in which the Binet IQ was above +2 SDs and the K-ABC was below +2 SDs. Implication for the assessment of gifted children is discussed.
