Fantasy Play in 5- and 6-Year-Old Children

We studied the verbal pretend play of 5- and 6-year-old boys and girls to delineate age and sex differences during the later preoperational period. Sixteen children with average language ability were paired by age and sex and were videotaped for three 15-min intervals. Verbal interactions were transcribed, and the pretend play was classified as object fantasy, imaginative action plans/themes, or fantasy roles. Language ilsed for pretend play increased in proportion to all utterances with age. Older children referred to more invented objects than younger ones but primarily in the service of realistic action formats. Girls' conversations were scored as having significantly more verbal pretending than boys' and a higher proportion of it referred to play roles. There were both age and sex differences in the types of themes, toys used, and roles enacted, including more sex-typed behavior in older children. The continued increase in the proportion of pretend play to all verbal interaction with age and the characteristics of play behavior is consistent with developmental theory.     

Do 5- and 6-Year-Old Children Attempt to Appear Fair to Others?

Abstract

Children come to prefer fair distributions at the age of 5 to 6?years. But do they actually want to be fair, or do they want to appear fair to others? In three conditions, an experimenter initially distributed chocolates to 5-/6-year-old participants and partners they were paired with. Participants always possessed, through some means, two chocolates when the experimenter returned after a brief absence, and they had to decide whether to take an extra one for themselves. To measure the extent to which children were concerned with actually being fair versus appearing fair, two conditions were created in which children were led to believe that the experimenter did not know that the distributions had become equal. In the windfall condition, a confederate gave one additional chocolate to the participant, and in the partner condition, the partner transferred one chocolate to the participant. Compared to the control condition, participants who passed the false belief task in both of these conditions tried to appear fair in their distribution. Thus 5-/6-year-old children seem to prefer appearing fair to others regardless of the situation.     

Experiences of Longing in Norwegian and Swedish 4- and 5-Year-Old Children

Longing can be defined as a blend of the primary emotions of happiness and sadness. These primary emotions are experienced very early by children, and the meanings of the words happiness and sadness are also known by children early in their verbal development. To find out at what age children are able to understand and use the more developed concept of longing, the authors interviewed 74 preschoolers (4- and 5-year-olds) in Norway and Sweden about their experiences of longing. Chi-square analyses showed age and sex differences in knowledge of the concept, and some differences between categories of longing were also significant. Results showed that young children's ability to understand and use the concept of longing appears to be limited and that girls seem to mature earlier in this respect than boys do.     

The Understanding of Pans in 3- to 6-Year-Old Children

In this study, we examined the extent to which preschool children were able to understand pans (continuous sideward shifts of a scene generated by rotating the camera around a virtual axis), one of the most typical technical elements of films. This was done by showing 60 participating children a film in which a teddy bear asked them questions about pan sequences. The questions could be answered correctly only if the underlying pan was understood. The study revealed that the increase in the children's comprehension of the pans was significantly correlated with age and was facilitated by gains in visual working memory (VWM). It was found that VWM in 3 year olds is generally so low that they are still not able to understand any pan sequences. Most of the pans were understood by those children who could remember the locations of two simple objects. This VWM level is sex dependent and is usually reached by boys at age 4 and by girls at age 5; thus, boys understand pans quite a bit earlier. Perception speed, pan speed, and television consumption played rather limited roles. An appropriate model for the understanding of pans is subsequently introduced and discussed.     

Resolving Power of the Perceptual-and Sensorimotor Systems in 6- to 10-Year-Old Children

Children aged 6 to 10 were tested on their ability to move accurately and to perceptually evaluate their motor response. Subjects performed a directional and an amplitude visuo-manual aiming task without vision of their moving limb. They were asked to correct their error, after completion of their movements, only if they felt they were not accurate. Terminal aiming errors and correction responses (adjustments) were analyzed, and threshold detection was determined relative to terminal aiming error. Action accuracy and evaluation of action accuracy are two abilities that do not develop synchronously. Moreover, the relationship between these abilities depends on whether accuracy and direction or amplitude are required. Amplitude undergoes more corrections than direction, suggesting that the spatial system of reference involved depends more upon the coding of the final position than on direction. Two spatial comparators, operating on the basis of two types of evaluation, seem to have a variably distinct contribution to movement and perception accuracy, according to age.     

Explaining Variability: Numerical Representations in 4- to 8-Year-Old Children

The present study aims to examine relations between number representations and various sources of individual differences within early stages of development of number representations. The mental number line has been found to develop from a logarithmic to a more linear representation. Sources under investigation are counting skills and executive functions and are set out against mental number lines from 0 to 10 and 0 to 100 in a sample of 4- to 8-year-old children (N = 80). Findings indicate that counting skills, inhibition, and updating are the most important predictors of the shape of the mental number line over and above age-related developmental differences, with number lines from 0 to 10 being linear to a large extent and number lines from 0 to 100 developing from a random pattern toward logarithmic representations. The shape of the mental number line was found to predict scores on the number comparison task only on the smaller-scale comparison task.     

Comparison of Mothers', Fathers', and Teachers' Reports on Problem Behavior in 5- to 6-Year-Old Children

Evidence exists that there is low agreement between multiple informants reporting on children's and adolescents' behavior problems. Few studies, however, focus on agreement between informants in specific age groups. This study examined correspondence and disagreement between mother, father, and teacher reports of problem behavior by analyzing CBCL and TRF data of 2 nonclinical samples of 5- to 6-year-old preschool children (N = 424). Findings indicated that interrater agreement was low to moderate. This was shown by the intercorrelations, the explained variance in regression analyses and the little overlap in the number of children rated as behaviorally disturbed by all 3 informants. Agreement between mother and father reports was highest, whereas agreement between mother and teacher reports was lowest. Disagreement between informants was highest for internalizing problems. Potential explanations for the lack of agreement are discussed. Guidelines are formulated to refine assessment and optimize clinical decision-making processes.     

Adjective Semantics, World Knowledge and Visual Context: Comprehension of Size Terms by 2- to 7-Year-Old Dutch-Speaking Children

The interpretation of size terms involves constructing contextually-relevant reference points by combining visual cues with knowledge of typical object sizes. This study aims to establish at what age children learn to integrate these two sources of information in the interpretation process and tests comprehension of the Dutch adjectives groot ‘big’ and klein ‘small’ by 2- to 7-year-old children. The results demonstrate that there is a gradual increase in the ability to inhibit visual cues and to use world knowledge for interpreting size terms. 2- and 3-year-old children only used the extremes of the perceptual range as reference points. From age four onwards children, like adults, used a cut-off point in the mid-zone of a series. From age five on, children were able to integrate world knowledge and perceptual context. Although 7-year-olds could make subtle distinctions between sizes of various object classes, their performance on incongruent items was not yet adult-like.     

Simulating the Acquisition of Verb Inflection in Typically Developing Children and Children With Developmental Language Disorder in English and Spanish

Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection. Such difficulties are less apparent in languages with rich verb morphology like Spanish and Italian. Here we show how these differential profiles can be understood in terms of an interaction between properties of the input language, and the child's ability to learn predictive relations between linguistic elements that are separated within a sentence. We apply a simple associative learning model to sequential English and Spanish stimuli and show how the model's ability to associate cues occurring earlier in time with later outcomes affects the acquisition of verb inflection in English more than in Spanish. We relate this to the high frequency of the English bare form (which acts as a default) and the English process of question formation, which means that (unlike in Spanish) bare forms frequently occur in third-person singular contexts. Finally, we hypothesize that the pro-drop nature of Spanish makes it easier to associate person and number cues with the verb inflection than in English. Since the factors that conspire to make English verb inflection particularly challenging for learners with weak sequential learning abilities are much reduced or absent in Spanish, this provides an explanation for why learning Spanish verb inflection is relatively unaffected in children with DLD.     

Traditional Literacy Skills and Internet Use Among 8- to 12-Year-Old Children

Ninety children in third through sixth grade attending an elementary school in western Canada completed a 15-item rating scale of their Internet use across home, school, and community contexts. Children's literacy skills were assessed with standardized measures of reading fluency and sentence comprehension and teacher ratings of reading and writing ability. Results suggest that Internet use during childhood is a complex behavior that varies across children and across contexts. Instant messaging and community-based Internet use during childhood were associated with decreased literacy skills, while other applications used at home and school were associated with increased literacy skills.     

The Role of Language in Temporal Cognition in 6- to 10-Year-Old Children

The ability to recognize temporal patterns and position events in time emerges during the preschool years and is refined in middle childhood. This study explored individual differences in temporal cognition in relation to verbal and nonverbal abilities. Children (30 boys, 32 girls; M_age = 8;2, age range = 6;0?10;8) completed 3 temporal-cognition tasks measuring estimation of temporal distance (how far events are from the present), knowledge of conventional times of events (specific days or months of events), and flexibility in using the calendar system (arranging nonconsecutive months in order), along with assessments of nonverbal intelligence, verbal short-term memory, visual-spatial working memory, receptive vocabulary, receptive grammar, and reading mastery. Controlling for age, performance across temporal-cognition tasks correlated with language abilities; nonverbal abilities accounted for little to no additional variance. The findings link language skills with the acquisition of conventional time patterns; such patterns developed alongside the ability to gauge distances of events in the past or future and form an organized timeline.     

Prevalence of Attention-Deficit/Hyperactivity Disorder Symptoms in 4- to 17-Year-Old Children in the General Population

The purposes of this study were (a) to estimate the prevalence of Attention-Deficit/Hyperactivity Disorder (AD/HD) symptoms in the general preschool and school population; and (b) to analyze the influence of gender, age, and socioeconomic status (SES) variables on AD/HD symptoms. Out of the 80,000 preschool and schoolchildren living in Manizales, Colombia, a random sample of 540 children was selected. Two gender, three age (4- to 5-year olds, 6- to 11 -year olds, and 12- to 17-year olds), and three SES (low, middle, and high) groups were used. The 18 DSM-IV symptoms corresponding to AD/HD Criterion A were assessed on a scale of 0 (never) to 3 (almost always). All three demographic variables established statistically significant differences: AD/HD symptoms were more frequent in 6-to 11-year-old, low-SES, male participants. DSM-IV Criterion A for AD/HD was fulfilled by 19.8% of the boys and 12.3% of the girls. However, this difference was marginally significant only in the AD/HD Subtype I: Combined. It was concluded that demographic variables are significant correlates of the AD/HD diagnosis. The prevalence found in this study was higher than usually reported, even though only the symptomatic DSM-IV AD/HD criterion was analyzed. We failed to confirm the assumed AD/HD gender ratio.     

The Effect of Plausible Versus Implausible Balance Scale Feedback on the Expectancies of 3- to 4-Year-Old Children

Previous studies (Case, 1985 Case , R. ( 1985 ). Intellectual development: Birth to adulthood . New York , NY : Academic . [Google Scholar]; Siegler, 1981 Siegler , R. S. ( 1981 ). Developmental sequences within and between concepts . Monographs of the Society for Research in Child Development , 46 , 1 – 84 . [Google Scholar]) have shown that children under the age of 5 years have little understanding of balance scales when required to encode the influence of weight or distance from the fulcrum. More recently, however, Halford, Andrews, Dalton, Boag, and Zielinski (2002 Halford , G. S. , Andrews , G. , Dalton , C. , Boag , C. , & Zielinski , T. ( 2002 ). Young children's performance on the balance scale: The influence of relational complexity . Journal of Experimental Child Psychology , 81 , 417 – 445 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) noted that an understanding based on weight alone is present even in 2-year-olds. In all these experiments, weight was varied using multiple objects of the same weight. Consequently, the children's decisions could have been based upon visual features (size, number) without necessarily taking the weight into account. The present study investigated whether young children are able to correctly encode the relevance of weight in influencing the behavior of a balance scale. We studied how well 3- to 4-year-old children learn to use one of two different weights (of equal appearance) to tip the scale. In the plausible condition, the heavy weight produced the desired outcome. In the implausible condition, the light weight caused the scale to tip. Only 4-year-olds' performance differed between conditions by learning more effectively in the plausible than the implausible condition. Our results suggest that children younger than 4 years of age have not yet developed clear expectations of the role of weights on the movements of a balance scale.     

Inaccuracy of Perceived Competence Ratings Is Associated With Problem Behaviors in 5-Year-Old Children

The authors examined problem behaviors in preschool children as a function of perceived competence. Prior research has demonstrated a link between inaccuracy of self-perceptions and teacher-reported externalizing behaviors in preschool aged boys. This study extended past research by adding data collected from observed behaviors in a laboratory setting, as well as parent reports of internalizing and externalizing behaviors. Five-year-old children completed the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PSPCSA) in the lab, participated in a 10-min puzzle interaction task with their cotwin and mother, and completed a short task assessing cognitive abilities. Children were grouped into 3 self-esteem categories (unrealistically low, realistic, and unrealistically high) based on comparisons of self-reported (PSPCSA) versus actual competencies for maternal acceptance, peer acceptance, and cognitive competence. Results showed that children who overreported their maternal acceptance and peer acceptance had significantly more parent-reported externalizing problems as well as internalizing problems. There were no significant differences in accuracy for cognitive competence. The findings from this study underscore the negative impact of unrealistically high self-appraisal on problem behaviors in young children.     

A Developmental Vocabulary Assessment for Parents (DVAP): Validating Parental Report of Vocabulary Size in 2- to 7-Year-Old Children

Measuring individual differences in children's emerging language abilities is important to researchers and clinicians alike. The 2 most widely used methods for assessing children's vocabulary both have limitations: Experimenter-administered tests are time-consuming and expensive, and parent questionnaires have only been designed for children up to 37 months of age. Here, we test the validity of a new assessment to fill this gap: the Developmental Vocabulary Assessment for Parents (DVAP). In 4 experiments, we assess the reliability of this measure and its concurrent and predictive validity in samples of 2- to 7-year-old children. We found that the DVAP provides a rapid, cost-effective alternative to experimenter-administered vocabulary tests for children.

Estimated Risk of Developing Selected DSM-IV Disorders Among 5-Year-Old Children with Prenatal Cocaine Exposure

We estimated childhood risk of developing selected DSM-IV Disorders, including Attention-Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD), and Separation Anxiety Disorder (SAD), in children with prenatal cocaine exposure (PCE). Children were enrolled prospectively at birth (n = 476) with prenatal drug exposures documented by maternal interview, urine and meconium assays. Study participants included 400 African-American children from the birth cohort, 208 cocaine-exposed (CE) and 192 non-cocaine-exposed (NCE), who attended a 5-year follow-up assessment and whose caregiver completed the Computerized Diagnostic Interview Schedule for Children. Under a generalized linear model (logistic link), Fisher’s exact methods were used to estimate the PCE-associated relative risk (RR) of these disorders. Our results indicated a modest but statistically robust elevation of ADHD risk associated with increasing levels of PCE (p < 0.05). Binary comparison of CE versus NCE children indicated no PCE-associated RR. Estimated cumulative incidence proportions among CE children were 2.9% for ADHD (vs 3.1% NCE); 1.4% for SAD (vs 1.6% NCE); and 4.3% for ODD (vs 6.8% NCE). Our findings suggest evidence of increased risk of ADHD (but not ODD or SAD) in relation to an increasing gradient of PCE during gestation.

Psychometric Evaluation of 5- and 7-Year-Old Children's Self-Reports of Conduct Problems

Past research suggests that young children are incapable of reporting information about their own behavior problems. To test this, we examined the validity and the usefulness of children's self-reports in the E-Risk Study, a nationally representative birth cohort of 2,232 children. We used the Berkeley Puppet Interview to obtain children's self-reports of conduct problems when they were 5-years old and the Dominic-R when they were 7-years old. We also collected information about the children and their families by interviewing mothers, sending questionnaires to teachers, and rating examiners' observations during home visits. Results indicate that when children's self-reports are gathered with structured and developmentally appropriate instruments, they are shown to be valid measures: conduct problems reported by the children themselves were associated with known correlates including individual characteristics (e.g., IQ), related behaviors (e.g., hyperactivity), and family variables (e.g., economic disadvantages). Observed correlations closely matched effect sizes reported in the literature using adults' reports of children's behavioral problems. In addition, children's self-reports can be useful: both measures distinguished children meeting DSM-IV criteria for research diagnoses of conduct disorder. Children's reports also contributed unique information not provided by adults. For research and clinical purposes, young children's self-reports can be viewed as a valuable complement to adults' ratings and observational measures of children's behavior problems.     

Imbalances and Impairments in Mental State Talk of Children with Internalizing and Externalizing Problems

ABSTRACT

The aims of this study were to investigate the associations between impairments and imbalances in children’s mental state talk, attachment security and abuse/neglect experiences, and to study how much of the variance in internalizing and externalizing problems was explained by mentalization problems. The sample included 100 Turkish children (M Age = 7.00 (SD = 2.01), 38% girls) referred to a outpatient psychotherapy clinic. Children were administered an attachment-based story stem task in order to code attachment security and different categories of mental state talk, including the extent of their direction (self vs other), balance, and appropriateness. Parents and teachers filled out socio-behavioral function scales. Findings indicated a significant positive association between externalizing problems and impaired mentalization. Internalizing problems were associated with mentalizing the other at the expense of one’s own mental states and underusing emotions. Attachment insecurity and adverse experiences were associated with mentalization impairments and imbalances. Finally, underuse of emotions and self-focused mental state talk predicted internalizing problems and impaired mental state talk predicted externalizing problems at trend level of significance. Qualitative analyses supported the results, which suggest that whereas children with externalizing problems suffer from severe mentalization deficits, children with internalizing problems undermentalize about themselves and emotions.
