Acoustic emphasis in four year olds

Acoustic emphasis may convey a range of subtle discourse distinctions, yet little is known about how this complex ability develops in children. This paper presents a first investigation of the factors which influence the production of acoustic prominence in young children’s spontaneous speech. In a production experiment, SVO sentences were elicited from 4 year olds who were asked to describe events in a video. Children were found to place more acoustic prominence both on ‘new’ words and on words that were ‘given’ but had shifted to a more accessible position within the discourse. This effect of accessibility concurs with recent studies of adult speech. We conclude that, by age four, children show appropriate, adult-like use of acoustic prominence, suggesting sensitivity to a variety of discourse distinctions.     

初中学生自尊特点的初步研究

对991名城乡在校初中生施以Coopersmith自尊问卷（25条目版）测验。对问卷的测量学分析发现：该自尊问卷的中文版具有较高的信度,其与有关测量工具之间的效标关联效度合乎逻辑;对被试自尊特点的分析发现：初中阶段学生的自尊存在极显著的年级差异,初中二年级开始自尊极显著地降低;初中生的自尊不存在性别差异;城市被试的自尊在总体上高于农村被试,但城乡因素与被试的性别有交互作用;独生子女的自尊高于非独生子女,但这一差异仅存在于初中一年级。     

The functional concern of mothers for their infants

The Functional Maternal Concern of mothers for their infants was assessed (with an Index derived from Caldwell's Home Observation for the Measurement of the Environment.) when 36 children, heterogeneous with respect to social status, were 6- and 18-months-old. Scores on this Index were related to the mother's IQ and education, as well as to certain temperamental characteristics of the children: cooperativeness and happiness. The Index proved stable over the time period of 6 to 18 months and yielded better predictability of Stanford Binet scores at 48 months than the Bayley Infant test scores. Moreover, there appears to be a minimal level of maternal concern needed to facilitate the child's development which seems to be especially important for the second year of life.     

Concurrent validity of the Cognitive Abilities Scale and Binet IV for nonvocal 2- and 3-year-olds

The concurrent validity of the Nonvocal Cognitive Quotient (NVCQ) of the Cognitive Abilities Scale (CAS) and the Binet IV was examined for 2- and 3-year-olds referred to Project Find. Adequate concurrent validity was found for the CAS NVCQ and the Binet IV Verbal Comprehension at both age levels as well as for the Nonverbal Reasoning/ Visualization factor of the Binet IV at age 3. A significant, but moderate correlation was obtained with 2-year-olds for the NVCQ and the Binet IV Nonverbal Reasoning/ Visualization factor, the Binet IV scores being significantly higher scores. Differences in the results for the 2-year-olds are discussed. The implications of the results are presented.     

Factor analytic study of the Piers-Harris Children's Self-Concept Scale

A factor analysis of the Piers-Harris Self-Concept Scale was conducted with a biracial u sample of children over a wide age range. The Scale was completed by 348 10-17 year old students in a rural community. Seven factors of 10 had sufficient item loadings to be interpretable. Six matched those found in the manual and an additional factor was found relating to Aggression. Race, sex, and age relationships are also reported for these seven factors.     

The role of epistemic and social characteristics in children’s selective trust: Three meta‐analyses

Over the last 15 years, researchers have been increasingly interested in understanding the nature and development of children’s selective trust. Three meta‐analyses were conducted on a total of 51 unique studies (88 experiments) to provide a quantitative overview of 3‐ to 6‐year‐old children’s selective trust in an informant based on the informant’s epistemic or social characteristics, and to examine the relation between age and children’s selective trust decisions. The first and second meta‐analyses found that children displayed medium‐to‐large pooled effects in favor of trusting the informant who was knowledgeable or the informant with positive social characteristics. Moderator analyses revealed that 4‐year‐olds were more likely to endorse knowledgeable informants than 3‐year‐olds. The third meta‐analysis examined cases where two informants simultaneously differed in their epistemic and social characteristics. The results revealed that 3‐year‐old children did not selectively endorse informants who were more knowledgeable but had negative social characteristics over informants who were less knowledgeable but had positive social characteristics. However, 4‐ to 6‐year‐olds consistently prioritized epistemic cues over social characteristics when deciding who to trust. Together, these meta‐analyses suggest that epistemic and social characteristics are both valuable to children when they evaluate the reliability of informants. Moreover, with age, children place greater value on epistemic characteristics when deciding whether to endorse an informant’s testimony. Implications for the development of epistemic trust and the design of studies of children’s selective trust are discussed.     

The learning of surface structure clues to deep structure by a puppet show technique

Fifty-six children were classified in terms of their developmental level on the linguistic structure “John is easy/eager to please”, and an experiment was carried out teaching them “new” (nonsense) words in related transformations by a puppet show technique. These transformations serve as frames for differentiating those new words which indicate a surface structure derived from a transformed deep structure, from those which do not. Results showed that children used different strategies at different developmental levels. Of children who did not use fixed strategies, only children who had correctly performed on all normal adult words (“Passers”) were able to learn which deep structures were called for by some of the new words; all other groups performed at chance levels on all types of new words. However, even these Passers performed correctly only on words given in structures indicating that the tested structure was to be treated as a transformation. The possibility of a language-learning principle related to the marked/unmarked distinction in natural languages is discussed.     

Auditory abilities of speakers who persisted, or recovered, from stuttering

OBJECTIVE: The purpose of this study was to see whether participants who persist in their stutter have poorer sensitivity in a backward masking task compared to those participants who recover from their stutter. DESIGN: The auditory sensitivity of 30 children who stutter was tested on absolute threshold, simultaneous masking, backward masking with a broadband and with a notched noise masker. The participants had been seen and diagnosed as stuttering at least 1 year before their 12th birthday. The participants were assessed again at age 12 plus to establish whether their stutter had persisted or recovered. Persistence or recovery was based on participant's, parent's and researcher's assessment and Riley's [Riley, G. D. (1994). Stuttering severity instrument for children and adults (3rd ed.). Austin, TX: Pro-Ed.] Stuttering Severity Instrument-3. Based on this assessment, 12 speakers had persisted and 18 had recovered from stuttering. RESULTS: Thresholds differed significantly between persistent and recovered groups for the broadband backward-masked stimulus (thresholds being higher for the persistent group). CONCLUSIONS: Backward masking performance at teenage is one factor that distinguishes speakers who persist in their stutter from those who recover. Education objectives: Readers of this article should: (1) explain why auditory factors have been implicated in stuttering; (2) summarise the work that has examined whether peripheral, and/or central, hearing are problems in stuttering; (3) explain how the hearing ability of persistent and recovered stutterers may differ; (4) discuss how hearing disorders have been implicated in other language disorders.     

Relationships Between Scores on the General Purpose Abbreviated Battery of Stanford-Binet IV,Peabody Picture Vocabulary Test-Revised,Columbia Mental Maturity Scale,and Goodenough-Harris Drawing Test

This study investigated the correlations among the “General Purpose Abbreviated Battery” of the Stanford-Binet IV: Fourth Edition, the Peabody Picture Vocabulary Test-Revised, the Columbia Mental Maturity Scale, and the Goodenough-Harris Drawing Test. A third-grade class of 23 children (11 boys, 12 girls) took all four of the tests, and the intercorrelations of the total scores of the four tests were calculated. The Binet IV and Peabody correlation was statistically significant (p < .01) as was the correlation between Binet IV and Columbia (p < .05). The correlation between Binet IV and Goodenough-Harris was not statistically significant (p > .05).

     

The association between stuttering, Brown''s factors, and phonological categories in child stutterers ranging in age between 2 and 12 years

Though the phonological difficulty of a word might reasonably be supposed to influence whether a word is stuttered, it has recently been reported that the incidence of stuttering does not depend on this factor in child stutterers. This conclusion is reexamined in the current report. Data are employed that were obtained from groups of child stutterers (and their controls) who vary in age and severity of their disorder. First, it is shown that the measure of phonological difficulty reveals differences in phonological ability for children of different ages (stutterers and fluent controls). The properties of words with regard to whether they are function words or content words, their position in the sentence, their length, and the phoneme that they start with vary between phonological categories (referred to as “Brown's factors”). Since these factors could influence whether words are stuttered in their own right, they may led to apparent differences in stuttering between words in different phonological categories that are spurious. Alternatively, these factors may disguise influences that phonological categories have on stuttering. It is shown in the next analysis that the words in the various phonological categories differ with regard to Brown's factors. In the final analysis, the proportion of words stuttered for words in each phonological category are analyzed so that any influence Brown's factors might have are removed by treating the factors as covariates. No dependence of stuttering on phonological category is observed for age group, stutterer's severity, or word types (stuttered word or word following the stuttered word). Thus, phonological difficulty as measured here and elsewhere does not appear to be a major factor governing the incidence of stuttering in children.     

Psychometric properties of the Movement Assessment Battery for Children‐Checklist as a screening instrument for children with a developmental co‐ordination disorder

Background: The Checklist of the Movement Assessment Battery for Children (MABC) was developed to screen children for movement difficulties in the school situation. However, the psychometric properties of the Checklist have not been investigated in detail. Aim: The psychometric properties of the M‐ABC Checklist were investigated including its usefulness as a screening instrument. Samples: A group of 120 children, 6 to 11 years old, randomly selected from mainstream schools and a group of 64 children, 6 to 9 years old, referred for assessment of their motor functioning. Methods: A reliability analysis was performed to investigate whether the 48 items of the Checklist measure the same construct. Construct validity was investigated by means of a factor analysis. And lastly, the sensitivity, specificity and positive predictive value of the Checklist were investigated by comparing the performance of children on both the Test and Checklist of the M‐ABC. Results: The items of the Checklist measure the same construct. Seven factors were obtained after factor analysis, revealing that the Checklist measures a broad range of motor skills. The Checklist met the standards for sensitivity in all age groups, except in the 8‐year‐old group, where too many children with motor problems were not detected. With the exception of the 6‐year‐old children, specificity was poor. The positive predictive value was acceptable, except for the 7‐year‐old children. Conclusion: the Checklist proved to meet standards for reliability and most aspects of validity. Its use by teachers for screening children with movement difficulties can be recommended.     

Psychometric properties of the Basic Family Relations Inventory (BFRI)

The aim of this study was to analyze the factor structure and internal consistency of the Basic Family Relations Inventory (BFRI) in a non-probabilistic convenience sample of 442 participants (221 couples). Exploratory factor analysis resulted in three components. In a second-order factor analysis, the three components were grouped into two factors: the Conjugal factor, which refers to how the people who exercise the parental role interact with each other (generally, the parental couple), and the Parenting factor, which represents the way in which the parental couple treat their children. Both first- and second-order factors had high reliability indices. It was concluded that the 25-item BFRI is a valid instrument to evaluate the two-dimensional model of the basic family relations theory.     

Person,setting, and interaction contributions to nursery school social behavior patterns1

Within a nursery school environment, 8,930 behavioral observations were taken on 17 preschool children in six settings over a two-month period. Two different data analysis techniques were used. The aggregate analysis showed that person, setting, and interaction all contributed significantly to behavior patterns. The setting was significantly stronger than person. The individual analysis found that subjects' median Person Pattern values were correlated significantly and negatively with IQ and age, suggesting that younger children and those with lower IQ's had more consistent behavior across different settings. This was also true of children who had been at the school more than one year. Implications for predicting behavior were discussed, noting the need to study person and setting relative to one another for particular behaviors in different categories of environments.     

A behavioral assessment scale for attention deficit disorder in brazilian children based on DSM-IIIR criteria

A teacher scale based on DSM-III-R diagnostic criteria for attention deficit hyperactivity disorder (ADHD) was developed for the behavioral assessment of children in Brazil. A total of 2, 082 children (782 males and 1,300 females) with a mean age of 11.2 years who were attending a public school in the greater Rio de Janeiro area were the subjects of this study. Two factors (Hyperactivity-Impulsivity and Inattention) were extracted from a principal-factor analysis conducted on the data, and the factor structure of the scale was found to be stable. Ratings of boys were higher than ratings of girls, and younger children had higher ratings than older children for both factors. Test-retest reliability for each item of the scale ranged from .56 to .70. The data are discussed in view of current controversies in the factor structure of teacher ratings of DSM-III-R ADHD symptoms.This research was supported by FINEP (42.88.0138.00) and FUNPENE.

Cognitive function of youths born to mothers with opioid and poly-substance abuse problems during pregnancy

Previous research has provided inconclusive evidence regarding the neuropsychological difficulties of children born to mothers partaking in opioid or poly-drug use during pregnancy. Little is known about how these children fare as they get older. The present longitudinal study includes follow-up data on 45 children born to mothers who used heroin and poly-drugs and a group of 48 children without prenatal drug exposure. Most of the drug-exposed youths were placed in permanent foster or adoptive homes before one year of age. The youths (ages 17 to 21) were administered 10 neuropsychological tests. The drug-exposed youths had cognitive and fine motor functions within the normal range compared to population norms but performed significantly worse than the non-exposed group. There were indications of generally lower cognitive functions rather than specific problems with executive functioning. Lower mean birthweight in the risk group (619 grams mean difference, p < .001) only partially mediated the group differences in cognitive functioning. There was a tendency for youths who had few and early changes in their caregivers or who were born to mothers who had used the least number of different drugs during pregnancy to have the best cognitive scores. The study indicates that youths born to mothers who used multiple drugs during pregnancy are vulnerable relative to their peers within a wide range of cognitive functions. The vulnerability seems to be related not only to the mother’s drug use during pregnancy but also to factors such as birthweight and unstable parental care during infancy.     

The school adjustment of South Asian immigrant children in the United States

This study examined the school adjustment process among South Asian children who had immigrated to the United States with their parents, and who had below-average grades. Both risk and protective factors for dropping out of school were explored in the context of the traditions, familial values, and social norms of South Asians. Data were collected from 75 parents and 75 children in separate semistructured interviews. Content analysis revealed three major themes: congruence of the parents' and school's views on the value of education, congruence of the parents' and children's beliefs that education is the tool to achieve goals, and determination of the children to achieve goals. The low level of proficiency in English was found to be a critical factor in low achievement and school failure. It was concluded that parental encouragement to succeed, in conjunction with teachers' efforts, can be used to facilitate children's school adjustment. Strategies for assisting immigrant children are discussed.     

Predicting cognitive recovery from closed head-injury in children and adolescents

Longitudinal data from 84 head-injured children and adolescents, who were tested at three points in the first year postinjury, were analyzed to determine the best combination of demographic, injury-related, and behavioral factors predicting cognitive performance. Dependent variables were language, memory, visuomotor, and speeded performance factor scores obtained through confirmatory factor analyses of an extensive test battery. Multiple regression analyses indicated that injury severity and the existence of previous psychological, physical, or cognitive disorders were primary for predicting acute (1 month post-hospital discharge) performance for older subjects. For younger subjects, however, parental marital status was the most important correlate of acute cognitive performance. Those residing in homes with both parents fared better than children in one-parent families. At 6 months and 1 year postinjury, the older subjects who performed most poorly initially remained the most impaired. For younger children, acute cognitive standing was also an important predictor of later performance, but parental marital status remained a crucial influence on their longer-term recovery of cognitive skills.     

Longitudinal Study of Mild Delinquency and In-School Problem Behaviors During Junior High School1

This research investigates repetitive problem behavior (in-school problems and mild delinquency) in Japanese junior high school students from their first to third year (12–15 years old) and examines the risk factors for repetitive problem behavior among parent–child relationships, school, individual, and lifestyle factors. An analysis of the longitudinal data of 470 students (Data Set 1) found that repeated problem behavior in school was affected by low self-control, poor relationships with teachers, and lack of parental monitoring. Repeated mild delinquent behavior was affected by parental violence, poor relationships with mothers, less sleep duration, and not belonging to club activities. Some students exhibited both mild delinquency and in-school problems. Students who experienced problem behavior 10 times or more in their second year had often experienced some problem behavior (1–9 times) in their first year. Analysis of the longitudinal data of 368 students (Data Set 2) showed that in many cases, students who exhibited repeated delinquent behavior in their second year continued to exhibit problem behavior after they became third-year students. Though the number of students with repetitive mild delinquency that was totally remedied in their third year was small, a low incidence of parental violence was seen as an antecedent factor for students who did not commit mild delinquency in their third year in spite of a high frequency of delinquency in their second year.     

Family and School Psychosocial Environment (FSPE): development of a brief questionnaire measuring perceived psychosocial environments in children/siblings

The aim of the study was to develop a short Swedish standardized, factor analyzed and cross-validated, family and school psychosocial environment questionnaire (FSPE). The study was based on 244 Swedish girls and boys, 10-19 years old, who filled in the FSPE. Maximum likelihood factor analysis, promax rotation, yielded six primary factors, based on absolute ratings. Since the factors were somewhat correlated, two broader secondary factors, with satisfactory reliabilities, were also included in the form, named Warmth, support and openness from parents, siblings and peers, and Family conflicts and school discipline, respectively. Means and standard deviations for girls and boys showed sex differences in most of the factors. Because the children participated anonymously they could report about spanking without negative consequences. Indeed, 8.1% of the children had been spanked by their parents. Based on relative ratings, two factors were identified, covering environmental questions about "more than, the same as or less than" a sibling. Only 6.6% of the children rated their environment exactly the same on the Family Psychosocial Environment (FPE) factors, compared to a sibling within the family. Thus the majority reported environmental differences. Further research is proposed to evaluate such differences and relations to personality, genotype-environment correlation and genetic mediation.
