Conceptual tempo as a moderator variable in predicting first grade achievement test scores

This study examined the utility of a set of tests for predicting the academic achievement of separate samples of impulsive and reflective first graders. The predictor tests were the Peabody Picture Vocabulary Test, the Columbia Mental Maturity Scale, Wepman's Auditory Discrimination Test, the ITPA Sound Blending Subtest, the WISC Digit Span Subtest, and Kaufman's WISC-R Verbal Comprehension Factor (Comprehension, Information, Similarities, and Vocabulary). The criterion measures were drawn from the Stanford Achievement Test and included scores for Total Auditory, Total Mathematics, Total Reading, Vocabulary and Listening Comprehension. Multiple regression analyses revealed that (a) for three of the five criterion variables, the optimal equations for predicting the achievement test scores differed for impulsives and reflectives, and (b) given the same predictor scores, the predicted achievement of impulsive and reflective children different considerably. It was concluded that conceptual tempo is an important moderator variable in predicting academic performance.     

Relationship between language skills and academic achievement in first grade

The ability of scores on the Early Prevention of School Failure battery to predict Stanford Achievement Test scores was examined. Participants included 280 first-grade students who were administered the battery at the beginning of kindergarten and the Stanford Achievement Test at the end of first grade. Principal factor analysis based on the oblique rotation exhibited simple structure between scores on the Peabody Picture Vocabulary Test-Revised, the Preschool Language Scale, and the Stanford Achievement Test (verbal or language factor), with the Draw-A-Man test and the Developmental Test of Visual-Motor Integration-Revised loading on a separate factor (motor factor). Results suggest that language-based skills were highly associated with later academic performance in school-aged children.     

Caregiving by low‐income adolescent mothers and the language abilities of their 30‐month‐old children

The primary question of interest in this study was: Are the caregiving practices of low‐income, teenage mothers during the first 2 years of their children's lives predictive of individual differences in the language abilities of their 30‐month‐old children? This question was addressed with a sample of 76 teenage mothers and their children who were participating in a family support program. Various measures of caregiving behavior, assessed when the children were 6, 12, and 24 months old, were significantly related to scores on the Preschool Language Scale—3, the Expressive One Word Picture Vocabulary Test, and Receptive One‐Word Picture Vocabulary Tests of the children.     

Use of the Peabody Picture Vocabulary Test with the educationally handicapped

Despite widespread use of the Peabody Picture Vocabulary Test (PPVT) as a measure of intelligence for educationally handicapped students, few studies have related PPVT scores of such students to their scores on the Wechsler Intelligence Scale for Children (WISC). Using 100 public school students consecutively referred for learning difficulties, their mean PPVT IQ (97.75) was found to be consistently and significantly higher than WISC Full Scale IQ (89.65), Verbal IQ (88.68), and Performance IQ (92.73). Correlations between the PPVT IQ and the WISC Full Scale, Verbal, and Performance IQs were .70, .69, and .54, respectively. A tabular summary of previous studies comparing PPVT and WISC IQs is included.     

Cognitive and motivational determinants of children's humor responses

Cognitive and motivational influences on children's humor responses were examined. Forty-eight Caucasian children from three economically heterogeneous schools were tested. Equal numbers of middle SES and lower SES boys and girls from kindergarten and third grade were shown 12 aggression and dependency cartoons of different difficulty levels. Three responses to each cartoon were recorded: mirth, funniness rating, and comprehension score. Results support aspects of both psychodynamic and cognitive theories of humor response. All children preferred aggressive themes to dependency themes, and third graders especially showed attenuated response to dependency cartoons. Funniness ratings decreased as difficulty levels increased. IQ, as assessed by the Peabody Picture Vocabulary Test-R, was positively related to humor. Mirth responses and funniness ratings increased as comprehension increased.     

A console for the interactive on-line administration of psychological tests

A computer controlled console for on-line psychological testing of psychiatric patients is described. The Peabody Picture Vocabulary Test and the Kelly Role Construct Repertory Test are computer administered using three visual, one auditory, and two response modes. Test data are analyzed, interpreted, and incorporated into a program-written psychological report. Benefits and other applications from such a system are noted.     

Patterns of language impairment and behaviour in boys excluded from school

Background. High levels of behaviour problems are found in children with language impairments, but less is known about the level and nature of language impairment in children with severe behavioural problems. In particular, previous data suggest that at primary age, receptive impairments are more closely related to behaviour problems, whereas expressive language has a closer link at a later age. Aims. The study assessed expressive and receptive language problems in boys excluded from primary and secondary schools, to investigate the extent of impairment, the pattern of relations between age, receptive and expressive language, and relations with different aspects of behaviour. Sample. Nineteen boys (8–16 years of age) who had been excluded from school and 19 non‐excluded controls matched for age and school participated. Method. The sample was given assessments of: receptive language from the British Picture Vocabulary Scale (BPVS), and Wechsler Objective Language Dimensions (WOLD); expressive‐language evaluations from the Wechsler Intelligence Scale for Children (WISC); auditory working memory evaluations from the Clinical Evaluation of Language Fundamentals (CELF); verbal reasoning (from the WISC); and non‐verbal IQ assessments Raven's matrices. Teachers completed behaviour ratings using the Strengths and Difficulties Questionnaire (SDQ). Results. Excluded boys were significantly poorer than controls on expressive measures but similar on receptive language and non‐verbal IQ. Boys excluded from primary school were poorer than controls on auditory working memory. Expressive problems were linked with high levels of emotional symptoms. Conclusion. Many of the excluded boys had previously unidentified language problems, supporting the need for early recognition and assessment of language in boys with behaviour problems. Expressive problems in particular may be a risk factor.     

Early language processing efficiency predicts later receptive vocabulary outcomes in children born preterm

As rates of prematurity continue to rise, identifying which preterm children are at increased risk for learning disabilities is a public health imperative. Identifying continuities between early and later skills in this vulnerable population can also illuminate fundamental neuropsychological processes that support learning in all children. At 18 months adjusted age, we used socioeconomic status (SES), medical variables, parent-reported vocabulary, scores on the Bayley Scales of Infant and Toddler Development (third edition) language composite, and children’s lexical processing speed in the looking-while-listening (LWL) task as predictor variables in a sample of 30 preterm children. Receptive vocabulary as measured by the Peabody Picture Vocabulary Test (fourth edition) at 36 months was the outcome. Receptive vocabulary was correlated with SES, but uncorrelated with degree of prematurity or a composite of medical risk. Importantly, lexical processing speed was the strongest predictor of receptive vocabulary (r = ?.81), accounting for 30% unique variance. Individual differences in lexical processing efficiency may be able to serve as a marker for information processing skills that are critical for language learning.     

Computer administration of the Peabody Picture Vocabulary Test to young children

Computer-controlled administration of the Peabody Picture Vocabulary Test to children between the ages of 4 and 13 years was shown to be feasible without the presence of a live examiner. Test-retest correlation coefficients were obtained in the range from .54 to .74 and were not significantly different from those obtained with manual administration in the PPVT standardization sample. Practice effects and IQ differences between the two forms of the test were nonsignificant.     

Developmental picture norms: Relationships between name agreement,familiarity, and visual complexity for child and adult ratings of two sets of line drawings

Developmental differences in name agreement, familiarity, and visual complexity in response to line drawings of common objects were obtained from children and adults. Sixty-one pictures were taken from the Peabody Picture Vocabulary Test-Revised and 259 pictures were taken from the set normed for adults by Snodgrass and Vanderwart (1980). Although there were some differences between the two sets of pictures, the present results replicated the relative independence of these three measures, which was reported by Snodgrass and Vanderwart for adults. Children and adults showed substantial agreement on the names of the pictures. Although the children’s ratings were lower on all measures, the differences were trivial for most pictures. We concluded that judgments of familiarity, complexity, and the names of line drawings of common objects are based primarily on information processing accomplished prior to age 7.     

Speech and Language Disorders in Kenyan Children: Adapting Tools for Regions with Few Assessment Resources

This study sought to adapt a battery of Western speech and language assessment tools to a rural Kenyan setting. The tool was developed for children whose first language was KiGiryama, a Bantu language. A total of 539 Kenyan children (males=271, females=268, ethnicity=100% Kigiryama) were recruited. Data were initially collected from 52 children (pilot assessments), and then from a larger group of 487 children (152 cerebral malaria, 156 severe malaria and seizures, 179 unexposed). The language assessments were based upon the Content, Form and Use (C/F/U) model. The assessment was based upon the adapted versions of the Peabody Picture Vocabulary Test, Test for the Reception of Grammar, Renfrew Action Picture Test, Pragmatics Profile of Everyday Communication Skills in Children, Test of Word Finding and language specific tests of lexical semantics, higher level language. Preliminary measures of construct validity suggested that the theoretical assumptions behind the construction of the assessments were appropriate and re-test and inter-rater reliability scores were acceptable. These findings illustrate the potential to adapt Western speech and language assessments in other languages and settings, particularly those in which there is a paucity of standardised tools.     

The impact of socioeconomic status on teenage mothers and children who received early intervention

To determine the early school age effects of an intervention program for low SES, black teenage mothers and their term and preterm infants, a subsample of 61 mother-child dyads was assessed when the children were 5 to 8 years of age. The mothers and children were videotaped in a storytelling interaction together and then interviewed and tested. The child interviews included the Pictorial Scale of Perceived Competence, the Peabody Picture Vocabulary Test, the Wide Range Achievement Test, and the Bender Visual Motor Gestalt Test. The maternal interviews included a demographic questionnaire, the Rosenberg Self Esteem Scale, the Eyberg Child Behavior Inventory, the Parenting Stress Index, and the Vocabulary subtest of the Wechsler Adult Intelligence Scale. Analyses of variance yielded no intervention effects and no effects of prematurity on any of the child or mother measures. Correlation analysis, however, yielded a number of significant relations between socioeconomic status and child and maternal outcome measures. These findings suggest that the effects of intervention may be short-term for this population, and that low socioeconomic status (SES) may override the effects of early intervention and prematurity by the time children reach school age.     

The visuospatial functions in children after cerebellar low‐grade astrocytoma surgery: A contribution to the pediatric neuropsychology of the cerebellum

The aim of this study was to specify whether cerebellar lesions cause visuospatial impairments in children. The study sample consisted of 40 children with low‐grade cerebellar astrocytoma, who underwent surgical treatment and 40 healthy controls matched with regard to age and sex. Visuospatial abilities were tested using the spatial WISC‐R subtests (Block Design and Object Assembly), Rey–Osterrieth Complex Figure, Benton Judgment of Line Orientation Test, PEBL Mental Rotation Task, and Benton Visual Retention Test. To exclude general diffuse intellectual dysfunction, the WISC‐R Verbal Intelligence IQ, Performance IQ, and Full‐Scale IQ scores were analysed. Post‐surgical medical consequences were measured with the International Cooperative Ataxia Rating Scale. Compared to controls, the cerebellar group manifested problems with mental rotation of objects, visuospatial organization, planning, and spatial construction processes which could not be explained by medical complications or general intellectual retardation. The intensity of visuospatial syndrome highly depends on cerebellar lesion side. Patients with left‐sided cerebellar lesions display more severe spatial problems than those with right‐sided cerebellar lesions. In conclusion, focal cerebellar lesions in children affect their visuospatial ability. The impairments profile is characterized by deficits in complex spatial processes such as visuospatial organization and mental rotation, requiring reconstruction of visual stimuli using the imagination, while elementary sensory analysis and perception as well as spatial processes requiring direct manipulation of objects are relatively better preserved. This pattern is analogous to the one previously observed in adult population and appears to be typical for cerebellar pathology in general, regardless of age.     

Carolina Picture Vocabulary Test: validation with hearing-impaired students

When mean Carolina Picture Vocabulary Test standard scores were compared with WISC-R Performance Scale IQs significant differences were observed. The Carolina test scores were also correlated with both Performance IQs and the Performance Scale subtest scores. Most correlations were minimal as the two tests were independent; only WISC-R Picture Arrangement scores correlated significantly with Carolina scores. These outcomes coupled with the technical limitations of the Carolina raise serious questions regarding its utility for hearing-impaired children.     

The Role of Paternal Age in the Prediction of Offspring Intelligence

Recent evidence suggests that paternal age at birth influences myriad developmental outcomes among children, but few studies have examined the possibility for father's age to influence children's intellectual development among a sample of high-risk families. The authors use data from the Fragile Families and Child Wellbeing Study to examine the association between paternal age at birth among 480 male and 449 female children's verbal IQ scores, as assessed with a version of the Peabody Picture Vocabulary Test at 9 years old. The nonlinear association between paternal age and children's verbal intelligence was also examined. Paternal age at birth appears to have a marginally significant nonlinear relationship with male children's verbal IQ scores, despite controlling for a number of possible confounders associated with both young and advanced paternal age.     

The effects of primary reward on the I.Q. performance of grade-school children as a function of initial I.Q. level

The effect of candy reward on I.Q. scores was investigated in 72 first- and second-grade children. All subjects were administered Form A of the Peabody Picture Vocabulary Test and, based upon these scores, were divided into three blocks: low, middle, and high. From each block, subjects were randomly assigned to one of three conditions (contingent reward, noncontingent reward, or no reward) that were in effect during administration of Form B. Results showed that candy given contingent upon each correct response increased I.Q. scores for the initially low scoring subjects, but had no influence on the scores of middle and high scoring subjects.     

The Ability to Encode Facial and Emotional Expressions by Educable Mentally Retarded and Nonretarded Children

The object of the present study was to investigate whether 20 educable mentally retarded (EMR) children matched for verbal mental age on the Peabody Picture Vocabulary Test (PPVT; Dunn, 1965) with 20 nonretarded (NR) controls were adept in identifying emotional facial expressions and producing the equivalent word adjectives. I also reassessed the relationship between the phase of identifying facial expressions (i.e., happy, sad, angry, and scared) and the phase of producing emotional word adjectives, consisting of 16 emotional linguistic constructions (4 short stories for each of the adjectives) between higher in verbal ability educable mentally retarded (HEMR) children and higher in verbal ability nonretarded controls (HNRC) and between low in verbal ability educable mentally retarded (LEMR) children and low in verbal ability nonretarded controls (LNRC). There were no significant differences between EMR and NR children in general, despite the fact that EMR children had deficits in receptive linguistic competence.

The Validity of Receptive and Expressive Vocabulary Measures with Spanish-Speaking Kindergarteners Learning English

Research examined construct meaning and validity for two new measures of receptive and expressive vocabulary for Spanish-speaking kindergarteners learning English. Substantive validity and generalizability of score meaning was assessed by examining correlations between an established measure (Peabody Picture Vocabulary Test–PPVT) and new measures (Stanford English Language Proficiency Test–SELP; Dynamic Indicators of Basic Early Literacy Skills, Word Use Fluency, DIBELS–WUF). Positive correlations between the SELP and PPVT supported validity of the SELP as a measure of receptive and expressive vocabulary for these children. DIBELS–WUF results were less clear with lower correlations between the PPVT raising questions about appropriateness.     

The use of the peabody picture vocabulary test with emotionally disturbed adolescents

The validity and reliability for the Peabody Picture Vocabulary Test (PPVT) was estimated with 52 nonpsychotic emotionally disturbed adolescents. Approximately 6 months after an initial administration of the PPVT and the Peabody Individual Achievement Test (PIAT), all children were retested. Significant increases in PPVT IQ and PIAT reading comprehension scores were found upon readministration. The internal consistency estimate for the initial PPVT administration showed considerable consistency in responding. A modest temporal stability estimate indicated a fair amount of fluctuation in scores over time. Concurrent validity coefficients for the PPVT indicated moderate to dependable relationships with PIAT subtests. Predictive validity estimates for the PPVT suggested moderate relationships with future achievement, accounting for some 26% of the variability in total achievement.
