Developmental Brain Research With Participants From Underprivileged Communities: Strategies for Recruitment,Participation, and Retention

Challenges associated with recruitment and retention of participants from underprivileged social communities, in addition to neuroscience researchers' unfamiliarity with these communities, possibly explain the limited number of individuals from these communities who participate in neuroscience research studies. The consequence is a scarcity of data in this fast‐growing segment of the population. In particular, developmental research involving children from ethnic minorities has yet to catch up with the number of studies available for middle‐class White children (Flores et al., 2002). This underrepresentation can lead to disparities in health and social services for children from these communities, as well as to a nonrepresentative knowledge base of child neurodevelopment. Developing and utilizing innovative and culturally sensitive approaches to recruiting participants from underprivileged communities can maximize their participation in research, as behavioral researchers have known for some time. Here, based on our experience recruiting low‐socioeconomic status (SES) Latino children from Los Angeles, we offer strategies to improve recruitment, involvement, and retention. We have a special focus on techniques relevant to recruiting for neuroimaging, which is associated with new challenges not faced to the same degree in research historically. Better inclusion of underrepresented children in research can ultimately lead to the development and improvement of effective public polices to support their needs, ranging from education to health care.     

Providing Quality Early Care and Education to Young Children Who Experience Maltreatment: A Review of the Literature

The current paper highlights the few studies that examine the role of early care and education on the developmental and early academic outcomes of children who experience maltreatment. First, we argue that children who experience maltreatment are at significant risk for poor developmental outcomes as a result of the chronic exposure to stress that is typical of this population. Recent evidence emphasizing the effects of stress on brain development is discussed. Next, the role of quality early care and education (ECE) experiences for children receiving services from child protective agencies are explored, underscoring three particular studies that examine the early educational experiences of children who receive child protective services as a result of maltreatment or exposure to violence. Finally, we focus on current approaches to improve the outcomes of children who experience maltreatment, within the context of ECE, and the implications for future research. Overall, this review serves as a call for international research efforts to explore the role of ECE on the developmental and early educational outcomes of this vulnerable population of children.     

Developmental effects of child abuse: A review

Most research investigating the effects of physical child abuse on children's development has been based on uncontrolled or poorly controlled studies having small samples, no long-term follow-up, and weak instrumentation. These studies, as well as some which have been more carefully designed, have generally suggested seriously detrimental developmental consequences in physical, intellectual, behavioral, and emotional areas. Some recent controlled follow-up studies challenge such a negative picture of abuse. In particular, a study by Elmer, which is probably the most carefully conducted study yet done, found that the harmful effects of abuse dissipated years after the abusive incident and that socioeconomic status (SES) and related factors may be more important than abuse in determining the course of child development. To improve the quality and clarity of future research on developmental effects of child abuse, this paper discusses, in four major areas, problems which plague the research. Definition: The extent, type, and frequency of abuse should be more carefully defined to allow studies to be compared. The types and amounts of social service interventions should also be specified. Generalization: Research should include more middle and upper SES children, more of the mildly and moderately abused, and more neglected children to allow generalization to the total population of maltreated children. Causality: Since developmental deficits may be the cause as well as the effects of abuse and because outside factors such as SES may lead to both the abuse and the deficits, there is a need for large-scale longitudinal studies which can untangle the cause and effect web of abuse by following children from birth and measuring many factors which might affect development (e.g., SES, birth abnormalities, abuse). Statistical Analysis: Future studies should always use statistical analysis and should obtain larger samples and utilize outcome and classification measures with demonstrated reliability and validity to increase statistical power.     

Environmental inequality and disparities in school readiness: The role of neurotoxic lead

Developmental science has increasingly scrutinized how environmental hazards influence child outcomes, but few studies examine how contaminants affect disparities in early skill formation. Linking research on environmental inequality and early childhood development, this study assessed whether differences in exposure to neurotoxic lead explain sociodemographic gaps in school readiness. Using panel data tracking a representative sample of 1266 Chicago children (50% female, 16% White, 30% Black, 49% Hispanic, μ_age = 5.2 months at baseline, collected 1994–2002), analyses quantified the contribution of lead contamination to class and racial disparities in vocabulary skills and attention problems at ages 4 and 5. Results suggested that lead contamination explains 15%–25% and 33%–66% of the disparities in each outcome, respectively, although imprecise estimates preclude drawing firm inferences about attention problems.     

Social Responsivity: Judging Signals of Young Children With and Without Developmental Delays

This was an experimental study of the ability of adults to detect 1 social signal that is important in social interactions, children's glances or looks at their social partners. Adult judges were either parents of children with developmental delays, parents of nondelayed children, or nonparents with little experience with children. Each participant viewed 120 videotaped episodes in which very young children's looks (of 2 types, either a focus on parent's face or nonface focus) occurred or no looking occurred. Half the episodes featured children with documented developmental delays and half featured nondelayed children. Participants made judgments about the occurrence of a look in each episode and rated their confidence in each judgment. Participants made more accurate and quicker responses to social looks by children without than those with developmental delays. Accuracy effects were qualified by interactions with type of look. Participants were more confident of their judgments of looks for nondelayed toddlers than those with delays. Signal detection statistics indicated that looks of delayed toddlers were harder to identify and that judges set a more stringent criterion for responding to those looks. No effects of judges' level of experience with delayed or nondelayed children were found. Implications of these findings for social interaction involving individuals with developmental delays are discussed.     

Family functioning and early learning practices in immigrant homes

Poverty‐related developmental‐risk theories dominate accounts of uneven levels of household functioning and effects on children. But immigrant parents may sustain norms and practices—stemming from heritage culture, selective migration, and social support—that buffer economic exigencies. Comparable levels of social‐emotional functioning in homes of foreign‐born Latino mothers were observed relative to native‐born Whites, despite sharp social‐class disparities, but learning activities were much weaker, drawing on a national sample of mothers with children aging from 9 to 48 months (n = 5,300). Asian‐heritage mothers reported weaker social functioning—greater martial conflict and depression—yet stronger learning practices. Mothers’ migration history, ethnicity, and social support helped to explain levels of functioning, after taking into account multiple indicators of class and poverty.     

Risk factors in early child development: Is prenatal cocaine/poly-drug exposure a key variable?

In order to explore the possible confounding effects of age, race, sex, and socioeconomic status on developmental outcomes of prenatal cocaine exposure, two matched samples of preschoolers (20 children with cocaine/polydrug in utero exposure and 20 children with no prenatal drug exposure) were compared on the Stanford-Binet: 4th ed. (S-B: 4th ed.), Social Skills Rating System, Vineland Adaptive Behavior Scale—Survey Form, Preschool Language Scale: 3rd ed. (PLS: 3rd ed.), and the Child Behavior Checklist. None of the 40 children had attended or were currently enrolled in preschool programs. Both groups had scores approximately one standard deviation below the expected mean in social skills, auditory comprehension, and expressive language. Likewise, externalizing behavior difficulties were approximately one standard deviation above the mean for both groups. Results suggest in utero drug exposure had no independent impact on cognitive, social, language, and behavioral developmental outcomes when the confounding variables of age, ethnicity, gender, and SES were controlled. © 1997 John Wiley & Sons, Inc.     

Dual-Earner Wives' And Husbands' Perceptions of Their Children's Day Care Experiences: Relationship to Personal Well-Being, Marital Stress, and Job Satisfaction

Dual-earner mothers and fathers whose children were enrolled in day care for at least two years were asked to rate the care environment, assess its effects on children's development and parent-child relations, and to provide assessments of marital stress, job satisfaction, and emotional support. Mothers and fathers did not differ significantly on any of the measures. A path model failed to provide support for the contention that personal well- being mediates influences from the broader social context on the parent-child relationship of day care children; however, it did show that the parent-child relationship may buffer certain influences from the broader social context on children's developmental status. The data are discussed with respect to the need to examine day care issues from an interrelated systems perspective.     

Social inequity and educational expansion in Slovenia

The study examines the relationship between social inequalities (stratificational, gender and other disparities) and schooling, including academic attainment, longitudinally, in Slovenia. The issue is indicated most clearly at the tertiary education level. The basic finding is the parallel between educational expansion and the diminution of social inequalities as measured by standard parameters. This was particularly evident in the 1990s. Inequalities are measured in terms of gender, parental education and occupation. The impact of parental education proves to be an indicative, observable and longitudinally comparative measure. Parental occupational status is also clearly linked to their children’s scholastic attainment, although there are difficulties in the formation of occupational strata. Further considered is the impact of school reforms over a lengthier period of time; there was not, however, any detectable impact. School and welfare policies, even financing, have little significance. There are clear indications that social disparities at school are continually regenerated, despite the decline established by standard measures. New forms of social disparities appear, through which the privileged ensure the continuation of privilege.     

The peer relations of mildly delayed and nonhandicapped preschool children in mainstreamed playgroups

Previously unacquainted groups of normally developing and mildly developmentally delayed preschool-age boys (N = 64) were brought together to form a series of 8 mainstreamed playgroups. Each playgroup consisted of 3 normally developing 3-year-olds, 3 normally developing 4-year-olds, and 2 mildly developmentally delayed 4-year-olds. The delayed children were matched with the normally developing older group for chronological age and with the normally developing younger group for developmental level. Each playgroup operated 5 days per week for 2 hours per day for a 4-week period. During that time, the peer-related social and play interactions of each child were videotaped, and peer sociometric ratings were obtained at the completion of each playgroup. Analyses of social participation and individual social behavior measures revealed that the analogue playgroup setting was appropriate for evaluating peer interactions, as expected developmental patterns emerged despite the presence of children heterogeneous with respect to chronological age and developmental status. The existence of a deficit in peer-related social interactions for mildly delayed children was supported in this investigation--a deficit that could not be attributed to reputational factors, the unavailability of responsive peers, inadequate matching procedures, unusual sample characteristics, or similar factors. Selected observational measures, peer preference patterns during free play, and peer sociometric ratings also indicated that the delayed children were perceived to be less competent and of lower social status. However, despite their relative isolation, important developmental opportunities were available for mildly delayed children in the mainstreamed playgroups. Possible processes responsible for these outcomes were discussed.     

Resilience in young children involved with child protective services

Child maltreatment increases the risk of poor developmental outcomes. However, some children display resilience, meaning they are high-functioning despite their adverse experiences. To date, few research studies have examined protective factors among very young maltreated children. Yet, domains of resilience, and the protective factors that promote resilience among maltreated children, are likely to differ by developmental stage. Drawing on ecological systems theory and life course theory, we examined how protective factors at multiple ecological levels across early childhood were related to social and cognitive resilience among very young children involved with child protective services. The results demonstrated that the buffering effects of protective factors varied by social or cognitive resilience and the cumulative effects of protective factors were more consistently related to later resilience than protective factors at specific time points. In addition, the influence of specific protective factors on resilience slightly varied by initial in-home or out-of-home placement. These findings have important policy and research implications for promoting optimal development among children involved in child protective services.     

Developmental Delays in Preschool Children: Assessment Over Time

Abstract

A 3‐year study yielded data on the characteristics and progress of preschool children with developmental delays of uncertain aetiology. Children were tested at six‐month intervals in their homes using standard developmental measures (Bayley, McCarthy, Gesell, Sequenced Inventory of Communication Development); additional information about children and families was gathered by personal interview. Findings support the use of standardized assessment techniques for determining developmental level of preschool delayed children. For the group as a whole there was stability of performance over time, but the rates of change varied according to child. Delays in developmental domains were frequently associated with social behavioural and adjustment problems. Some relationship was found between aetiology and rate of development. Analyses across time suggest that three assessments are needed before confident prediction can be made about developmental rate for individual children.     

Self-perceptions of first- and second-grade children with learning disabilities

The present study addressed the question of the effects of developmental positive bias and repeated experiences of failure on the self-perception of mainstreamed first-and second-grade Israeli children with learning disabilities. The self-perceptions of 44 children with learning disabilities and their 36 nondisabled classmates were assessed. In addition, teachers' evaluations and objective measures of cognitive performance and social acceptance were gathered. The children with learning disabilities were found to have a greater positive bias and lower self-perception in the cognitive competence domain than their normally achieving peers. Self-perceptions of peer acceptance among children with learning disabilities are similar to their normally achieving peers' self-perceptions, in spite of their significantly lower sociometric ratings and teacher evaluations in the social domain. These findings are analyzed in the context of the globality-specificity dimension of self-perceptions at the age level studied. The obtained pattern of self-perceptions is discussed in the light of the interrelationships between cognitive deficit and experimental factors among mainstreamed first- and second-grade children.     

Social Studies,Social Competence and Citizenship in Early Childhood Education: Developmental Principles Guide Appropriate Practice

The purpose of this article is to examine the nature of appropriate social studies education in the Kindergarten and Pre-Kindergarten years. The importance of social competence development as a basic foundation of the social studies in the early years of schooling is examined, with particular attention to the commonalities shared between goals and strategies for social competence and for civic ideals and practices. Knowledge of developmental direction in child development is described and illustrated as a tool for considering the importance of using close-to-home lessons built on children’s own experiences, prior to lessons about more distal concepts. Historical foundations of developmentally appropriate social studies are revisited, and their relevance is discussed, with regard to social studies education in the kindergartens and pre-kindergartens of today.     

Dual-Earner Wives' And Husbands' Perceptions of Their Children's Day Care Experiences: Relationship to Personal Well-Being,Marital Stress,and Job Satisfaction

Dual-earner mothers and fathers whose children were enrolled in day care for at least two years were asked to rate the care environment, assess its effects on children's development and parent–child relations, and to provide assessments of marital stress, job satisfaction, and emotional support. Mothers and fathers did not differ significantly on any of the measures. A path model failed to provide support for the contention that personal well- being mediates influences from the broader social context on the parent–child relationship of day care children; however, it did show that the parent–child relationship may buffer certain influences from the broader social context on children's developmental status. The data are discussed with respect to the need to examine day care issues from an interrelated systems perspective.     

Motivational Interventions That Work: Themes and Remaining Issues

We highlight major themes emerging from the articles in this special issue. These themes include (a) the importance of theoretical frameworks and clearly defined constructs for guiding the development of interventions, (b) a consideration of intervention effects on ethnic minority children, (c) the importance of positive social interactions and relationships among teachers and peers in school as a foundation for students' adjustment to and achievement in school, (d) the need for intervention programs to use strong research designs and measures to test their effectiveness, and (e) the importance of considering developmental issues when designing interventions. Issues with respect to each theme are discussed.     

Self-report measures of the home learning environment in large scale research: Measurement properties and associations with key developmental outcomes

Favourable home learning environments (HLEs) support children’s literacy, numeracy and social development. In large-scale research, HLE is typically measured by self-report survey, but there is little consistency between studies and many different items and latent constructs are observed. Little is known about the stability of these items and constructs over time when used in either longitudinal research or studies with children with a wide range of ages. A review of the literature shows commonalities and differences between approaches in research on HLE. When we tested the psychometric properties of a short-form measure of HLE with a Rasch item-response-model using longitudinal data from over 1600 Australian families, there was support for two dimensions of HLE—formal and informal learning frequency. We found that this measure was stable over the transitional period from pre-K to school as well as between gender and family language background. There were small but significant associations between the HLE measures and cognitive and behavioural developmental outcomes. We recommend that other measures of HLE could be similarly validated to assess their suitability for use in longitudinal research on learning environments. Recommendations are made for the future development of measures of broader constructs of the HLE.     

Early Intervention for Behaviour Problems in Young Children with Developmental Disabilities

This article reviews research on intervention for young children with dual developmental and behavioural problems. It makes a case for intervention to include family variables and to occur in the preschool years. Behaviour problems are common in young children with developmental disabilities. If untreated these problems are likely to persist and become more challenging and severe in adulthood. Behaviour problems interfere with cognitive, social and emotional development, create additional family stress, often lead to exclusion from community services, and result in additional financial costs to the community. Intervention research provides some support for the effectiveness of parent management training and interventions based upon applied behaviour analysis. However, randomised controlled trials with adequate follow-up periods are required, along with the measurement of outcomes for the family as a whole.     

Early Head Start and African American families: Impacts and mechanisms of child outcomes

Persistent disparities exist between African American children and their European American counterparts across developmental domains. Early childhood intervention may serve to promote more positive outcomes among African American children. The current study examined whether and how the Early Head Start (EHS) program benefited African American children at the end of the program, when they were 36 months of age, as well as the parenting these children experienced and how this affected their developmental outcomes. The data show a wide and strong pattern of impacts of EHS for African American children and families. Path analysis yielded findings that suggested a direct effect of EHS on specific child outcomes and parenting processes within this group of African American families. Parental supportiveness and cognitive stimulation emerged as important direct influences on African American children's outcomes and as pathways through which Early Head Start benefits these children. These findings are discussed in the context of early childhood intervention practice.     

Preschool teacher attachment,school readiness and risk of learning difficulties

Attachment is the emotional bond between children and their caregivers (parents or otherwise). Infants and young children usually have more than one selective attachment, and all of these attachment relationships, including those between children and teachers, have important effects on cognitive and social development. Secure attachment to a preschool teacher may help children to improve their preschool experience. Recent studies suggest that the adverse effect of inadequate preschool experiences can lead to skill deficiencies that mimic the effects of basic cognitive deficits. This study evaluates the relationships among attachment to preschool teachers, school readiness, and the risk for developing learning difficulties in preschoolers using three measures: the School Readiness 4-5 battery, the Precocious Identification of Learning Difficulties, and the Attachment Q Set. This study examined 152 preschoolers. The results showed that attachment to preschool teachers is related to linguistic development level, the psychomotor skills involved in school readiness, and learning difficulty risk.
