Factor and cluster analysis of the Intermediate Halstead Category Test

The factorial invariance of the six subtests of the Intermediate version of the Halstead Category Test (IHCT), as well as clusters of IHCT subtest patterns, were evaluated in a sample of 87 children with traumatic brain injuries. A two-factor solution was found which partially replicated that found in previous research with children with learning disabilities, supporting the assumption that the IHCT measures multiple underlying constructs in clinical populations. Four clusters were found, with differences between clusters determined to a substantial extent by relative accuracy on subtest 111, and to a less substantial extent by relative accuracy on subtests IV and V. Clinical and research implications are discussed.     

Autism and receptive dysphasia: Evaluation of comparative studies

Ten different studies comparing children with autism and receptive dysphasia are reviewed. Most of the studies aimed to characterize autism as a language disorder. The representativity of the samples are discussed according to heterogeneity of the autistic and dysphatic populations, and sex and social class distributions. Group differences and similarities are listed and discussed according to sample selection and matching procedures, age and sex distribution, social class membership, and the defining criteria of the two illnesses. It is concluded that the studies do not fullfill their aim, and that the project of comparing dysphatic and autistic children seems unfruitful. Group differences which seem unconnected with methodological difficulties, selection procedure, or group defining criteria, were found in parental background, use of gestures, articulation, and reading.     

At-risk children's causal inferences given emotional feedback and their understanding of the excuse-giving process

Italian male school children, ranging in age from 7 to 10 years, were identified as at-risk children on the basis of self-reports, teacher questionnaires, and peer nominations assessing aggression, emotional instability, and pro-social behaviour. Together with a normal control sample, these children participated in two studies guided by attribtional theory. In Study 1, following teacher emotional feedback of anger or sympathy for failure, attributional inferences regarding low ability or lack of effort as the cause of that failure were rated. In Study 2, controllable and uncontrollable causes of a social transgression were given, and participants rated the anticipated anger of the ‘victim’ and their intention to withhold or reveal the cause. Strong effects for both populations that were consistent with attributional predictions were reported. In addition, differences between the inferences, expectations, and behavioural intentions of the populations were found, with at-risk children being less likely to perceive sympathy as a cue for low ability, and anticipating more anger from others following a transgression, particularly when there was a ‘good’ (i.e. uncontrollable) reason for the broken social agreement. It was contended that the results support the social-cognitive approach to the understanding of mechanisms of risk and deviancy.     

Verb inflection and verb diversity in three populations: agrammatic speakers, normally developing children, and children with specific language impairment (SLI)

The present study focuses on the relation between a grammatical and a lexical-semantic aspect of verb production. The spontaneous speech of three different populations (normally developing children, agrammatic aphasics, and children with a specific language impairment) has been analyzed with respect to the proportion of finite clauses and the diversity of the produced lexical verbs. The group results show that in the three populations both the proportion of finite verbs and the variability of the lexical verbs is low. When the individual scores are considered, differences between the normally developing children and the language-impaired subjects show up. Whereas in normally developing children verb finiteness and verb variability go hand-in-hand, the reverse relationship between these variables is observed in the agrammatic aphasics and the children with a specific language impairment. Given this reverse relationship, it is probable to assume two separate disorders. We therefore suggest an impairment at the interface level where lexical information and syntactic structure are integrated during sentence production.     

The Boston Naming Test: Norm data and cue utilization in a sample of normal 6- and 7-year-old children

The object-naming abilities of 83 normal children were examined using the Boston Naming Test developed by E. Kaplan, H. Goodglass, and S. Weintraub (1976, The Boston Naming Test (experimental edition), unpublished test, Veterans Hospital, Boston, Massachusetts). There is currently a lack of available norms for this instrument, especially for populations of younger children. Cue utilization in this sample is explored and attention is focused upon possible gender differences in naming performance and cue strategies. Seven summary scores derived from the test are presented in this report. Results indicate that the Boston Naming Test can discriminate within a normal population sample of young children and provides a relatively normal distribution for six of seven derived scores. Boys were found to have a significantly greater number of items correctly named but no gender differences in cue utilization were evident. A major proportion of the children in this sample of 6- and 7-year-olds used phonological cues almost exclusively, rather than semantic cues also provided. Cue use was not related to age or spontaneously given responses, and none of the children were found to be highly proficient at using both types of cues.     

Developmental and mental health characteristics of children exposed to psychosocial adversity and stressors at the age of 18-months: Findings from a population-based cohort study

BackgroundPrior research on adverse experiences in early childhood has mainly focused on at-risk populations while studies of unselected populations are scarce. This topic therefore remains to be elucidated in broader child populations. Accordingly, the aim of this study was to examine if and to what extent children from a general population sample are exposed to psychosocial adversity and stressors in early childhood and whether the development and mental health of children with and without such exposure differ at the age of 18-months.MethodsA random sample of the Copenhagen Child Cohort (CCC2000) comprising 210 children and their parents participated in the study when the children were approximately 18-months. Information on exposures was obtained from a semi-structured interview including the Mannheim Parent Interview (MPI) and classified in agreement with the Multiaxial Classification of Child and Adolescent Psychiatric Disorders (ICD-10), and the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC: 0-3). Child development was assessed with the Bayley Scales of Infant and Toddler Development – Second Edition (BSID-II), while mental health was measured using the Child Behavior Check List (CBCL 1½-5).ResultsAmong the 210 children, 91 (43%) had been exposed to psychosocial adversity and persistent stressors. The exposed children differed from the non-exposed children by poorer cognitive development and behavioral regulation, as well as more attention problems and anxious/depressed symptoms. The children exposed to adverse caregiving environments were specifically more likely to have delayed cognitive development than the rest of the sample.ConclusionsIn a general population sample of children aged 18-months, exposure to psychosocial adversity and stressors was associated with poorer development and mental health in cognitive and affective domains. These findings highlight an avenue for further research with potential implications for early preventative practices.     

Emergent self-regulation skills among very young ethnic minority children: A confirmatory factor model

Emerging self-regulation skills were assessed in 407 low-income African American and Latino (primarily Mexican-origin) preschoolers. A battery of self-regulation tasks was administered when children were 2½ years old and again approximately 1 year later. Confirmatory factor analyses supported four components of self-regulation: inhibitory control, complex response inhibition, set shifting, and working memory. Complex response inhibition was too rare a skill in this sample to be detected reliably from measures collected at 2½ years of age, but it emerged from measures collected at 3½ years. In addition, significant ethnic differences were found in that African American children scored better on measures of complex response inhibition and set shifting, whereas Latino children scored better on measures of inhibitory control and working memory. Implications of study findings for measuring self-regulation in low-income ethnic diverse populations of young children, as well as for developing interventions to enhance self-regulation development, are discussed.     

Parents' education and mean change in intelligence

Bergman, L. R. Parents' education and mean change in intelligence. Scand. J. Psychol., 1973, 14, 273–281.-For 815 Swedish school children aged 9 in 1965, mean changes between 9 and 12 years are studied for Verbal Comprehension, Inductive ability, Spatial ability, and General Intelligence. Controlling for the initial values, children coming from educated homes tend to obtain larger positive changes than children coming from less educated homes. These differences are largest for boys, and in Verbal Comprehension. A comparison with other Swedish samples suggests that the present sample may be reasonably representative of many Swedish urban populations with regard to the problem under study.     

A Confirmatory Comparison of the Factor Structure of the Children's Depression Inventory between European American and African American Youth

We examined the factor structure of the Children's Depression Inventory (CDI) among a sample of 523 African American children (m age = 12.76) and a sample of 564 European American youth (m age = 12.43). Previous investigations have produced discrepant factor structures among samples of predominantly majority-culture children, but fewer investigations of the factor structure of the CDI have been conducted among non-European American samples. Confirmatory factor analyses of the original 5 factors identified by Kovacs (1983, 1991) revealed that the items had invariant measurement properties across the samples. The latent factor structure, however, revealed telling differences between the two samples. For European American youth, only one of the original five factors was meaningfully differentiated from the others, whereas for the African American youth, two of the factors clearly emerged as unique facets of depression. Consistent with other reports, between-group mean differences on the CDI and its factors were noted. We argue that further validation of the CDI among traditionally underserved populations is warranted. Predictive validation investigations, in particular, are needed to examine the relationship between CDI factor scores and clinical outcomes.     

Theory of mind development in Chinese children: a meta-analysis of false-belief understanding across cultures and languages

Theory of mind is claimed to develop universally among humans across cultures with vastly different folk psychologies. However, in the attempt to test and confirm a claim of universality, individual studies have been limited by small sample sizes, sample specificities, and an overwhelming focus on Anglo- European children. The current meta-analysis of children's false-belief performance provides the most comprehensive examination to date of theory-of-mind development in a population of non-Western children speaking non-Indo-European languages (i.e., Mandarin and Cantonese). The meta-analysis consisted of 196 Chinese conditions (127 from mainland China and 69 from Hong Kong), representing responses from more than 3,000 children, compared with 155 similar North American conditions (83 conditions from the United States and 72 conditions from Canada). The findings show parallel developmental trajectories of false-belief understanding for children in China and North America coupled with significant differences in the timing of development across communities-children's false-belief performance varied across different locales by as much as 2 or more years. These data support the importance of both universal trajectories and specific experiential factors in the development of theory of mind.     

Response monitoring, the error-related negativity, and differences in social behavior in autism

Children with autism not only display social impairments but also significant individual differences in social development. Understanding the source of these differences, as well as the nature of social impairments, is important for improved diagnosis and treatments for these children. Current theory and research suggests that individual differences in response monitoring, a specific function of the anterior cingulate cortex (ACC), may contribute to social-emotional and social-cognitive impairments and individual differences in autism. To examine this hypothesis, we used a modified flanker task to assess an ERP index of response monitoring, the error-related negativity (ERN), in a sample of higher function children with autism (HFA) and an IQ-matched control sample. The results revealed a significant Diagnostic group by Verbal IQ interaction on ERN amplitude indicating that the most verbally capable HFA children displayed significantly larger ERN amplitudes than did the control children. Within the HFA sample, greater ERN amplitude was also related to parent reports of fewer symptoms of social interaction impairments, fewer internalizing problems, but more externalizing problems, although these associations were reduced to nonsignificance when medication status was controlled. The latter results complement previous observations from imaging studies of a significant association between ACC activity and social symptoms and impairments in autism. The implications of these results for future research on brain-behavior relations, as well as treatment related research with children with autism are discussed.     

Are orthographic rules used by children with and without writing disabilities? / ¿Utilizan las reglas ortográficas los niños con y sin dificultades de aprendizaje en la escritura de palabras?

The aim of this study was to explore whether children with and without learning difficulties use orthographic rules to write words. To study this, two types of tasks from the Early Grade Writing Assessment (EGWA) test were used: (1) a dictation task which included pseudowords with an implicit orthographic rule; and (2) a dictation task which included words with arbitrary, unregulated orthography. An initial sample of 1,447 students from grades 1 to 3 of elementary school was selected. The results showed that the variables task type and grade were significant when explaining the differences found between the groups. These findings are discussed from the perspective of the orthographic representations self-teaching hypothesis as related to the orthographic depth hypothesis, associated with the orthographic transparency of Spanish.     

Visuomotor organization in the child: a neuropsychological approach

The ability of children to copy a complex figure was investigated by means of the Rey-Osterrieth complex figure and the corresponding methodology. The sample consisted of 420 children (boys and girls) aged 5 1/2 to 12 1/2 years. Responses indicate that the visuomotor ability involved in copying a complex figure increases with increasing age and that girls show significantly better performance than boys during the ages 8 1/2 to 12 1/2 years. The differences in performance can be attributed to differential neuropsychological strategies or functional differences that require further investigation.     

Predicting aggressive patterns in girls and boys: A developmental study

The aim of this multimethod, longitudinal study was to examine similarities and differences in aggressive expression and prediction among school-aged boys and girls. The primary research sample involved 174 children (93 females, 81 males). They were in the fourth grade at the beginning of the study, and the fifth grade at its conclusion. Embedded in the primary sample was a subgroup of 20 children identified as being highly aggressive (ten males, ten females), and a subgroup of 20 matched control children. The research measures included teachers' ratings of aggressive behavior, peer-nominations/reports of prior conflicts, individual interviews/self-ratings, and extensive behavioral observations. Analyses of the concurrent relations among measures pointed to a “public” cluster of measures (including peer-nominations, behaviors, and teacher ratings) and relatively “private” measures (ie, subjects' self-evaluations). In the primary sample, significant developmental trends were detected in the teacher ratings with increasing gender differentiation as children grew older. Few gender differences were observed in the high-aggressive subgroup, but the aggressive and the matched control groups differed on virtually all comparisons. Gender differences in predictability were a function of risk status, with high-aggressive girls showing as much stability as high-aggressive boys.     

Callous-unemotional traits and conduct problems in the prediction of conduct problem severity,aggression, and self-report of delinquency

The role of callous-unemotional (CU) traits and conduct problems in predicting conduct problem severity, severity and type of aggression, and self-reported delinquency at a 1-year follow-up was investigated in a sample of 98 children (mean age 12.43; SD = 1.72) recruited from a community-wide screening. Children with both CU traits and conduct problems had a greater number and variety of conduct problems at follow-up than children who at the screening had high levels of conduct problems alone. However, this poorer outcome for children with CU traits could largely be accounted for by differences in initial level of conduct problem severity. Children with CU traits and conduct problems were also at risk for showing higher levels of aggression, especially proactive aggression, and self-reported delinquency. Importantly, these outcomes could not be solely explained by initial level of conduct problem severity. Finally, CU traits predicted self-reported delinquency in some children who did not initially show high levels of conduct problems and this predictive relationship seemed to be strongest for girls in the sample who were high on CU traits but who did not show significant conduct problems.     

Subjective Wellbeing on the Tibetan Plateau: An Exploratory Investigation

While working on a project to build a school for Tibetan nomad children in a remote part of the Tibetan plateau, the author carried out the first empirical exploration of personal wellbeing with a small (n = 102) sample of ethnic Tibetans. Using the PWI survey instrument, significant age, gender, and education differences with respect to satisfaction with life were revealed. In addition, the magnitude of overall satisfaction with life was found to be more consistent with Western rather than Asian populations and, future security, standard of living, gender and age were identified as the strongest predictors of life satisfaction. This paper reports on the findings drawing on the literature, Buddhist philosophy and the author’s observations for explanation.     

Do the Wechsler scales underestimate the difference between verbal and performance abilities in children with language–related disorders?

The present paper examines the validity of the Wechsler scales with children with language-related disorders, with whom the scales were not originally normed. The general question is whether we can take measures of IQ, normed with a normal sample, and then validly use them as indicators of the same constructs with samples significantly different from the normed sample. In previous papers it was pointed out that the pattern structurally simple > moderately complex > complex tests can be observed in their IQ profiles within both the Verbal scale and the Performance scale. In this paper, it is hypothesized that this scatter of scores leads to an underestimation of the global V-P IQ differences for children with language-related disorders because there are more structurally complex tests on the Performance scale than on the Verbal scale. To test this hypothesis, "purer" V-P IQ differences were calculated by comparing the scores on Verbal and Performance tests of equal structural complexity. WPPSI and WISC-R data from four groups of children were analyzed: language-impaired children (n = 128), reading-impaired children (n = 112), children from dyslexic families (n = 51), and normal children (n = 49). When the effect of the difference in structural complexity was controlled for, it was found that the distribution of the revised V-P IQ difference was significantly more toward the negative end of the spectrum than the traditional V-P IQ differences for language-impaired and reading-impaired children, and approaching a significant level for children from dyslexic families. As hypothesized, there were no significant differences between the two distributions of V-P IQ differences for normal children. Practical and theoretical implications are discussed.     

Validation and Standardization of the Dutch Trauma Symptom Checklist for Young Children in a Normative and Clinical Sample

The study aimed to describe the psychometric properties of the Dutch version of the Trauma Symptom Checklist for Young Children (TSCYC) in normative and clinical populations in the Netherlands. Caregivers’ ratings on the TSCYC were obtained for 1,802 children from the normal population, and for 515 children from a clinical population of traumatized children. In the clinical sample, additional measures were taken. The internal consistency and test-retest reliability of TSCYC scales were adequate. Confirmatory factor analysis showed acceptable fit on the putative scale structure. Regarding criterion validity, the clinical sample scored significantly higher on all clinical scales when compared to the normal population sample. Within the clinical sample, significant associations were found between TSCYC scales and convergent scales of other instruments. The Posttraumatic Stress-Total subscale demonstrated excellent discriminative ability between traumatized children and children from the normal population. The Dutch version of the TSCYC proved a valid and reliable instrument to measure trauma symptoms in young children through caregiver report, similar to the original American version. Further comparisons with diagnostic interviews are warranted.
