Significant differences between individual subtest scaled scores and average scaled scores on the Wechsler Preschool and Primary Scale of Intelligence-Revised

This paper presents age-referenced tables that are used for determining significant differences between individual subtest scaled scores and average subtest scores on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R). The tables provide differences required at the .05 and .01 levels of significance between any Verbal scale subtest and the average of Verbal scale subtests, any Performance scale subtest and the average of Performance scale subtests, and any subtest with the average of all subtests administered. The information presented is useful for WPPSI-R profile analysis.     

Correlation of the Peabody Picture Vocabulary Test and the Wechsler Intelligence Scale for Children

Abstract

College freshman males whose fathers and mothers failed to complete educational undertakings more often discontinued their education than males whose parents had a converse educational history. Level of academic aptitude did not appear to be an influential factor in this relationship. Freshman females appeared to be similarly influenced by fathers, but this finding is not clearly unrelated to academic aptitude.     

The role of sex differences in the referral process as measured by the Peabody Picture Vocabulary Test-Revised and the Wechsler Intelligence Scale for Children-Revised

The Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) are two tests that are often used in the assessment process for special education referrals. Sex differences apparent in these tests were examined in a sample of Arkansas school children who were first-time referrals for a psychological evaluation. The subjects' PPVT-R standard scores, WISC-R IQ scores, and WISC-R subtest scores were divided into groups according to one-year intervals from ages 6 through 16. A separate 2 × 11 (subjects' sex x subjects' age) analysis of variance was performed for each dependent variable. Results indicated significant sex differences among WISC-R Full Scale, Verbal, and Performance IQs and PPVT-R standard scores (p < .01). Several WISC-R subtests also revealed significant sex differences. Further significant sex differences were indicated at several age groups on each dependent variable, with males consistently scoring higher than females on 87%. of the dependent measures excluding the WISC-R subtest Coding, on which females scored higher. Implications concerning the referral process are discussed.     

Performance of bilingual and monolingual Hispanic children on the Peabody Picture Vocabulary Test-Revised and the McCarthy Perceptual Performance Scale

This study evaluated the receptive vocabulary ability and nonverbal cognitive ability of 20 monolingual (Spanish-speaking) and 11 bilingual (Spanish/English-speaking) Mexican-American preschool children, ages 45 to 65 months. The children obtained significantly lower scores on the Peabody Picture Vocabulary Test-Revised (PPVT-R) than on the Perceptual Performance Scale of the McCarthy Scales of Children's Abilities. On both measures, the bilingual group obtained significantly higher scores than did the monolingual group. The results support prior recommendations that the PPVT-R not be used to estimate the intelligence level of Hispanic children.     

A table for determining probability of obtaining verbal and performance scale discrepancies on the Wechsler Preschool and Primary Scale of Intelligence-Revised

This brief report presents a table that may be used to determine the probability of obtaining various Verbal-Performance Scale discrepancies on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R). The table of differences is age-referenced and should be used to determine the reliability of differences between Verbal and Performance Scale IQs. It may be used in conjunction with Table 16 in the WPPSI-R manual, which reports the percentage of the standardization sample that evidence Verbal-Performance discrepancies of various magnitudes.     

Factor structure of the Wechsler Intelligence Scale for Children-Revised,Peabody Picture Vocabulary Test,and Peabody Individual Achievement Test in a psychiatric sample

This study analyzed the factor structure of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Picture Vocabulary Test (PPVT), and the Peabody Individual Achievement Test (PIAT) in a psychiatric sample that ranged in age from 6 to 16 years (mean age = 11.1 years; SD = 3.0). The resultant factor structure of this sample was compared with patterns reported on normal and learning-disabled children. The subjects were 329 children under inpatient and outpatient care who had been referred for emotional disturbances. The results were similar to previous factor analytic studies of the WISC-R and PIAT, showing four factors: Verbal Comprehension, Verbal Achievement, Perceptual Organization, and Number Facility. The implications for the interpretation of these tests in a psychiatric sample and the appropriateness of a maximum likelihood technique in analysis of psychometric data are discussed.     

Concurrent validity of the revised Peabody Picture Vocabulary Test

In this investigation, the relationships between the Revised Peabody Picture Vocabulary Test, the Peabody Individual Achievement Test, and McCarthy Scales of Children's Abilities were explored. The sample included 26 children randomly selected from three classes in an elementary school. The Revised Peabody Picture Vocabulary Test correlated positively and significantly with the Peabody Individual Achievement Test's total score (.53) and most of its subtests. The Revised Peabody Picture Vocabulary Test also correlated significantly with the Verbal, Quantitative, Memory, and General Cognitive Indexes of the McCarthy Scales (Median r = .76). The mean Peabody Picture Vocabulary Test score was 104.6 and nearly identical to the McCarthy General Cognitive Index (104.4) but significantly smaller than the Peabody Individual Achievement total test score (114.5).     

Comparison of reading disabled children's scores on the WISC-R,Peabody Picture Vocabulary Test,and Slosson Intelligence Test

Scores on the Slosson Intelligence Test and Peabody Picture Vocabulary Test, two frequently used screening devices, are examined to determine how well they predict scores on the Wechsler Intelligence Scale for Children—Revised. Two hundred seven children representing reading disabled children in the average classroom were administered each of the three measures of this study. The degree of relationship between the PPVT and the WISC-R was found to be.57, and the degree of relationship between the SIT and the WISC-R was found to be.73. The results of this study suggest that the PPVT and SIT measure different and/or limited aspects of a child's ability as measured by the WISC-R and are therefore only rough estimates of capacity to function in situations requiring what is generally termed intelligence.     

Effectiveness of the Peabody Picture Vocabulary Test with Seventh-Grade Pupils

Abstract

This is an exploration of college students’ motivations that affect their performance, and that might eventually provide educators with suggestions for program modifications. S's were 343 women's college freshmen. Student responses to the author's College Assessment Inventory gave information on eight student motivational variables. Students’ perceptions of meaningfulness of daily college tasks were positively related to overachievement, with r=.22, significant at .001 level. Field of interest (liberal arts and professional), relevance of college to the student's future goals, and warmth of interpersonal relations predicted voluntary dropout, with chi-squares significant beyond the .05 level. A combination of liberal arts, low on future goals, and low on warmth resulted In a 55 percent chance of a student's staying and a 41 percent chance of voluntarily dropping. A professional field" high on future goals, high on warmth combination indicated an 82 percent chance of staying and a 10 percent chance of voluntarily dropping. Further explorations seem called for, but practical applications are not yet warranted.     

The Peabody Picture Vocabulary Test and Naive versus Trained Examiners

The Peabody Picture Vocabulary Test is marketed as an instrument suitable for use by persons without special training in testing. A total of forty children, ranging from retarded to gifted, were tested in counter-balanced order by eight elementary school teachers and by three school psychologists. No significant differences between the S’s mean I.Q.’s in the experienced versus the naive examiner’s data were found and there were no significant treatment effects, trial effects or interactions. However, differences in the test results for certain individuals were large suggesting the necessity for cautious use in the absence of corroborating data.     

The Wechsler Preschool and Primary Scale of Intelligence: Difficulty order of subtest questions

Theoretically and pragmatically the subtest questions of the Wechsler Pre-school and Primary Scale of Intelligence are assumed to be ordered from least to most difficult. The purpose of this study was to test whether or not the order was appropriate for a sample other than that used for standardization. Data consisted of test records of 89 females and 62 males tested at a private school over four years. Mean Full Scale IQ of the sample was 118. Calculation of proportion of the sample passing each item and Guttman Reproducibility Coefficients for each subtest suggested changes in the order of questions of the Vocabulary, Picture Completion, Similarities, and Comprehension Subtests. However, though questions were misordered for the present sample as a result of presenting them in the order prescribed in the test manual, the misordering was not great enough to seriously affect subtest scores or the interpretation of intratest scatter.     

Use of the Peabody Picture Vocabulary Test with low-functioning autistic children

The Peabody Picture Vocabulary Test (Dunn, 1965) was adapted to facilitate administration to low-functioning autistic children who do not have a pointing response. By cutting the plates into individual pictures, children can respond by giving the examiner the target picture. Ten autistic and 10 preschool-aged children were given both the standard form (Form A) and the adapted form (Form C) by the same examiner less than one week apart. Several t-tests were calculated to test the hypotheses that the adaptation would not affect raw scores of normal, preschool-aged children; yet lowfunctioning autistic children would score significantly better on the adapted version. It was concluded that the two forms of the PPVT are equivalent forms when a pointing response exists, and it is therefore valid to use the published norms for the adapted version.     

An analysis of differential response patterns on the Peabody Picture Vocabulary Test-IIIB in struggling adult readers and third-grade children

This study examines the Peabody Picture Vocabulary Test-IIIB (PPVT-IIIB) performance of 130 adults identified as struggling readers, in comparison to 175 third-grade children. Response patterns to the items on the PPVT-IIIB by these two groups were investigated, focusing on items, semantic categories, and lexical features, including word length, word class, and word frequency. The score distributional properties of the two groups were different, but there were similarities and differences found in different response patterns. Analyses of word length, word class, and word frequency in the two groups?? performance resulted in counterintuitive findings for the adult participants. The struggling adult learners?? vocabulary repertoire might have been shaped by their real-life experiences rather than formal schooling. Implications and future research directions are discussed.     

The relationship between the Wechsler Intelligence Scale for Children-Revised and the Wechsler Intelligence Scale for Children-III scales and subtests with gifted children

Each year thousands of children are evaluated or reevaluated utilizing the current edition of the Wechsler Intelligence Scale to determine their eligibility for gifted programs. The Wechsler Intelligence Scale for Children-III (1991) is new enough that only limited research is available on how it compares to the previously used Wechsler Intelligence Scale for Children-Revised (1974). The purpose of this study was to determine the comparability between the previously dominant intelligence scale, the WISC-R, and the revised WISC-III with gifted children. The results of this study indicate that the latest revision (WISC-III) and the earlier version (WISC-R) produce remarkably similar scale and subtest scores when administered under clinical conditions to gifted children. All 51 children determined eligible through the administration of one of these two Wechsler tests would have been eligible for services had the other test been administered. The Verbal and Performance scale IQ scores were within two points of each other across the two test administrations, while only a one-point difference existed between the Full Scale IQ scores. The Arithmetic, Comprehension, and Object Assembly subtest scores were in high agreement across the two administrations (p<.01). The level of agreement between some subtests across the two administrations suggests that clinical judgment is just as important as scores in considering who is eligible for gifted programs.     

Bidirectionality in Self‐Regulation and Expressive Vocabulary: Comparisons Between Monolingual and Dual Language Learners in Preschool

Significant differences in language and self‐regulation skills exist among children when they enter formal schooling. Contributing to these language differences is a growing population of dual language learners (DLLs) in the United States. Given evidence linking self‐regulatory processes and language development, this study explored bidirectional associations between English expressive vocabulary and self‐regulation skills for monolingual English and DLL preschool children (N = 250) from mixed‐income families in Los Angeles. Across three time points, findings provide initial support for bidirectionality between these developing skills for both monolinguals and DLLs. Results provide strong empirical support for vocabulary serving as a leading indicator of self‐regulation skills in preschool. Findings also suggest that early self‐regulation skills play a particularly important role for vocabulary development.     

Relationships between scores on Stanford-Binet IV and Wechsler preschool and primary scale of intelligence

A kindergarten class of 9 boys and 11 girls took the 1986 Stanford-Binet Intelligence Scale (Fourth Edition) and the Wechsler Preschool and Primary Scale of Intelligence. Of 6 correlations of total scores and subtest pairs, only the correlation of total scores was statistically significant (p<.01).

Development and Validation of the Chinese Preschool Readiness Scale

Research Findings. A growing number of young children encounter group learning environment for the first time when entering preschool at age 3, yet their parents and teachers have no means to discern whether they are ready for this challenge. To address this uncertainty, this study developed and validated the Chinese Preschool Readiness Scale (CPRS), which assesses children’s readiness for successful adjustment to preschool. The scale was validated through EFA in Study 1, with 29 teachers who rated 288 children. The scale was further validated by ESEM and confirmatory factor analysis (CFA) in Study 2, with 46 teachers who rated 765 children. A five-factor CPRS was determined: self-care abilities and emotional maturity, cognitive and communications skills, social competence, learning dispositions, and classroom rules. The construct validity and internal reliability were satisfactory. Its concurrent validity was also established: (1) the CPRS scores were positively correlated with parent-rated self-regulation and (2) the social competence domain of CPRS was positively correlated with sensitive-cooperative behaviors and negatively correlated with anxious-withdrawn behaviors.Practice or Policy. The results supported further development and use of the CPRS to monitor children’s development upon entry at preschool. The findings also highlighted the need for more research on preschool readiness.
