A revised Prechtl Neurological Examination was administered to 510 singleton infants at term conceptional age to assess the influence of gestational age, race, and sex on neurobehavioral responses in a "typical" newborn population. The infants were born at 1 of 5 centers and were subjects of the NIH Collaborative Study on Antenatal Steroid Therapy. Of these babies, 392 were born at less than 37 weeks gestational age, whereas 118 infants were born at greater than or equal to 37 weeks. Of a total of 50 items of interest, 12 differed significantly based on race, 14 items differed in terms of gestational age at birth, and 5 items were influenced by the sex of the baby. These data suggest that singleton preterm infants born at differing gestational ages should not be considered to comprise a homogeneous sample. Further, caution should be exercised when considering babies of heterogeneous race groupings, and the babies' sex has minimal impact on neurobehavioral responses at term conceptional age.  相似文献

Using time-lapse video, we recorded the sleep/wake states of 95 preterm infants, born under 1500 g and cared for in three hospitals, for three 24-hr periods at 33 and 35 weeks conceptional age. The videotapes were scored in 5-min epochs for quiet sleep (QS); active sleep (AS); wakefulness (Wa); bout lengths of QS (QSBL), AS (ASBL), and waking (WaBL); nursing/caregiving periods (Crgv); bout lengths of Crgv (CrgvBL); and time out of the crib (OOC). The infants' sleep showed significant individual differences at each age, over age, and from day to nighttime. They showed developmental changes in QS, AS, Wa, and QSBL. QS and QSBL were positively related to caregiving time; ASBL was related to maternal age; and QS was related to gestational age and birth weight. Thus, very low birth weight preterm infants show marked stability and developmental change in the organization of the sleep/wake states from a very early age, and their states are related to demographic variables as well as temporal measures of caregiving.  相似文献

Individual differences in academic success were investigated in a geographically defined whole-population sample of very preterm children with a gestational age of less than 32 weeks or a birth weight of less than 1500 gm. The sample consisted of 264 very preterm children (75.6% of German-speaking survivors) and 264 controls matched for gender, socioeconomic status, marital status and age of mother, who were studied from birth. The present analyses focused on the impact of cognitive skills assessed at ages 6 and 8 on academic success at the age 13. IQ scores, prereading skills, reading, spelling, and math performance assessed during the last kindergarten year and again at the end of Grade 2 were used as predictors of academic success in early adolescence. Differences between very pretern children and controls in cognitive abilities already observed in earlier assessments remained stable over time, with controls on average performing more than half a standard deviation above the level of preterm children. Preterm children also performed poorer on the literacy measures and indicators of math performance. Multivariate and causal modeling revealed different prediction patterns for the two groups. Whereas IQ was particularly important for the prediction of academic success in the pre-term sample, general IQ was less relevant for the prediction of academic success in the control group. When subgroups of at-risk children were formed according to birth weight categories, we found that school problems were most pronounced for children with extremely low birth weight (1000 gm and less).  相似文献

The study investigates the preschool readiness of moderately preterm children and, in particular, the likely presence of learning disabilities at preschool age. Its theoretical model detects linguistic comprehension and expression; memory-related metacognition and cognition skills; orientation and motor coordination skills; premathematics and preliteracy ones. The research project involved an experimental group made up of 55 moderately preterm children (mean age?=?62 months, mean gestational age?=?34.6 weeks), without any clinical neonatal complications, and low birth weight (M?=?2,100 g, SD?=?350 g); a control group made up of 55 full-term children without pre- and perinatal complications. The children’s primary school reference teachers were given a questionnaire (Observative Questionnaire for Early Identification of Learning Disabilities), which was aimed at identifying any likely social and cognitive skill deficits at preschool age. The data, submitted to nonparametric univariate variance, show how scores of moderately preterm children in the metacognition [U (n1 e?n2?=?55)?=?35, p?=?0.04, r?=?0.49] are statistically lower, other cognitive skills (memory, orientation, and visual–motor coordination) [U (n1?e?n2?=?55)?=?32, p?=?0.02, r?=?0.45], premathematics [U (n1?e?n2?=?55)?=?32, p?=?0.02, r?=?0.44], and the total score [U (n1?e?n2?=?55)?=?31, p?=?0.02, r?=?0.12]. Such data would seem to suggest the need for hypothesizing preventive training and educational paths as a prerequisite for the development of the school abilities.  相似文献

Recent medical advancements have resulted in improved survival rates for “preterm” children, born before 37 weeks gestation. However, this population remains vulnerable to adverse physiological, neurological and emotional outcomes. Research suggests that the professionals involved with them as they enter and progress through school, such as teachers and educational psychologists (EPs), have limited knowledge of the vulnerabilities of children born preterm. Using a bio-psychosocial approach, this paper gives an overview of some common outcomes for children born preterm and makes suggestions for evidence-based interventions aimed at minimising adverse outcomes. Particular attention is paid to holistic environmental interventions, to which the EP might contribute and advise, including classroom moderations, a focus on play and language, and the potential value of delayed school entry.  相似文献

Cognitive impairment is common among children born very preterm (VPT), yet little is known about how this risk changes over time. To examine this issue, a regional cohort of 110 VPT (≤ 32 weeks gestation) and 113 full‐term (FT) born children was prospectively assessed at ages 4, 6, 9, and 12 years using the Wechsler Preschool and Primary Scale of Intelligence–Revised and then Wechsler Intelligence Scale for Children, 4th ed. At all ages, VPT children obtained lower scores than their FT born peers (p < .001). Growth curve modeling revealed stable cognitive trajectories across both groups. Neonatal white matter abnormalities and family socioeconomic adversity additively predicted cognitive risk. Despite some intraindividual variability, cognitive functioning of typically developing and high‐risk VPT children was stable and influenced by early neurological development and family rearing context.  相似文献

Prematurity may cause hippocampal compromise. Therefore, hippocampus‐dependent memory processes (recollection‐based retrieval) may be more impaired than hippocampus‐independent processes (familiarity‐based retrieval). The memory of 18 children born preterm with reduced hippocampal volumes, without neonatal complications (weeks of gestation < 34, weight < 1,600 g), and 15 controls (8–10 years) was tested using an item recognition task. While groups were equal in memory performance, dissociation was found: The event‐related potential (ERP) correlate of familiarity was intact in the preterm group, whereas the correlate of recollection was attenuated. A follow‐up experiment ruled out that this was due to general cognitive deficits. Furthermore, gestational age correlated with the ERP index of recollection. Thus, recognition memory in preterm children may be characterized by a compensation of attenuated recollection by familiarity.  相似文献

We investigated the effects of gestational age at birth on behavioral and electrophysiological measures of 135 medically healthy infants, studied at 42 weeks postconception, and stratified into 3 groups--early-born preterms, 26-32 weeks (n = 55); middle-group preterms, 33-37 weeks (n = 43); and fullterms, 38-41 weeks (n = 37). Subjects were studied behaviorally with the Assessment of Preterm Infants' Behavior (APIB) and electrophysiologically with brain electrical activity mapping (BEAM). Fullterms showed significantly better behavioral function than both preterm groups. Less difference was found between the preterm groups. EEG spectral and photic evoked response were of significantly less amplitude for the preterms than the fullterms. Path analysis showed gestational age effects on behavioral (3 of 6) and electrophysiological (13 of 17) variables due to postnatal complications. We conclude that some differences attributable to gestational age at birth are explained by the cumulative effect of minor but unavoidable complications associated with premature birth. We speculate that remaining effects may result from developmentally inappropriate sensorimotor stimulation consequent to the premature experience of an extrauterine environment.  相似文献

This study investigated how self-regulation contributes to the development of reading competence in an at-risk sample of 157 children born to adolescent mothers. It was hypothesized that reading readiness at age 5 would shape self-regulation at age 10, which in turn would influence reading competence at age 14. Based on structural equation modeling, it was concluded that self-regulation partially mediated the relationship between early reading skills and later reading competence. These findings suggest the importance of socioemotional and cognitive self-regulation in the development of reading competence; implications for classroom practice are discussed.  相似文献

Recent decades have witnessed dramatically improved survival rates for infants born prematurely, especially those born very and extremely preterm. Follow-up studies concerned with long-term neurodevelopmental outcomes for children born preterm indicate that these children are at high risk for a range of cognitive, learning, neuromotor, and behavioral difficulties. However, to date, most of the existing literature has tended to focus on the medical and developmental impact of preterm birth, with little consideration given to the educational implications. Addressing this research gap is important since cognitive and educational difficulties represent the most commonly occurring cluster of adverse outcomes affecting children born very or extremely preterm, with up to two thirds likely to require educational assistance during their school years. The goal of this review is to provide an overview of existing research findings relating to the educational needs of school-age preterm children. Methodological issues that need to be addressed in future outcome research relating to the developmental and educational needs of very preterm children are also highlighted. Finally, implications of existing findings for educational psychologists, counselors, teachers, and teacher educators are discussed in terms of the roles of society, education systems, schools, and teachers.  相似文献

The present study examined the influence of schooling during children's first and second years of preschool for children who experienced different amounts of preschool (i.e., one or two years), but who were essentially the same chronological age. Children (n = 76) were tested in the fall and spring of the school year using measures of self-regulation, decoding, letter knowledge, and vocabulary. Using hierarchical linear modeling (HLM), preschool was not associated with children's development of self-regulation in either year. For decoding and letter knowledge, children finishing their second year of preschool had higher scores, although both groups of children grew similarly during the school year. Thus, our results suggest that the first and second years of preschool are both systematically associated with decoding and letter knowledge gains, and the effects are cumulative (two years predicted greater gains overall than did one year of preschool). Finally, children's chronological age, and not whether they experienced one versus two years of preschool, predicted children's vocabulary and self-regulation outcomes. Implications for preschool curricula and instruction are discussed, including the increasing emphasis on literacy learning prior to kindergarten entry and the need to address self-regulation development along with academic learning.  相似文献

In a longitudinal study with the Neurobehavioral Maturity Assessment (NB-MAP), developmental changes and stability of individual differences were assessed in 2 independent samples of preterm infants ranging from 32 weeks conceptional age to term. Individual stability of response was assessed using regression analysis with repeated measures on subjects. The large majority of the functions tested showed highly significant developmental gains with age and highly significant individual stability of performance across age. These findings replicated well across the 2 cohorts. The results are discussed in the light of the neurobiological stage of development of preterm infants during the last 8 weeks prior to term.  相似文献

The present study investigated gender differences in social mastery motivation, vocabulary knowledge, behavioral self-regulation, and socioemotional skills and examined the relationships among this knowledge and these skills by gender. Participants were 134 Chinese children (68 boys, M age = 3.80; 66 girls, M age = 3.89) and their parents recruited through local kindergartens’ parent groups. The children were administered measures of social mastery motivation, vocabulary knowledge, behavioral self-regulation, and nonverbal intelligence. Parents reported their education level and children’s socioemotional skills. Research Findings: Results revealed that boys exhibited more social mastery interactions than girls, and girls showed better behavioral self-regulation and socioemotional skills than boys. Girls with higher social mastery interaction frequency demonstrated better vocabulary knowledge and socioemotional skills, whereas boys with higher social mastery interaction frequency showed lower behavioral self-regulation. Boys, who showed more positive affect during social mastery interactions, tended to have better expressive vocabulary, which facilitated their behavioral self-regulation. Practice or Policy: Findings highlight social mastery motivation as a potential factor that facilitates children’s early development, but it may contribute to boys and girls in different ways.  相似文献

ABSTRACT

Primary education is compulsory around the world. This means that around age 5 or 6, millions of children worldwide transition from home or preschool/kindergarten settings into primary school, with the success of this transition shaping school and life trajectories for years to come. Both developmental and environmental factors during early childhood spur tremendous change in children’s executive function (EF), a multi-component process fundamental to self-regulation and overall achievement. Successful self-regulation means that children can master their attention, emotions, and behaviors as they navigate public social spaces including the classroom and playground. Adaptive development of EF and self-regulation are critical, because primary school comes with heightened expectations for children to manage themselves effectively. In this special section of 4 articles that collectively span preschool through 5th grade, we take an integrative, whole-child approach to studying children’s regulatory processes and schooling outcomes. Special section authors explored conceptual frameworks, measurement approaches, and empirical research on the motor and behavioral aspects of self-regulation and their contributions to educational outcomes. Article themes include the importance of precise and nuanced measurement of regulatory processes in addition to academic skills; in-school and out-of-school time as unique contexts for development; multiple interrelated developmental domains important for EF and self-regulation, including visuo-spatial and visuo-motor skills; and the need to synthesize research on EF and self-regulation across developmental domains for efficacious application and interventions. In taking an integrative, whole-child approach to the study of self-regulation and schooling outcomes, these articles represent research that are important parts of the whole.  相似文献

This study replicated and extended the Feldman (2009) study by applying the developmental hierarchical-integrative model to understand the emergence of self-regulation. Participants included 360 children (48.6% boys; 62.8% identified as Caucasian and 36.9% African American) and their families, predominantly from a low-income, rural background. Families completed assessments on child physiological, attention, emotion, and self-regulation when children were 6-, 15-, 24-, and 36-month-old, when caregiver sensitivity was observationally assessed. A path model revealed that child attention regulation at 6 months predicted physiological regulation at 15 months, and child attention regulation at 15 months predicted emotion regulation at 24 months. Attention regulation at 24 months predicted better self-regulation at 36 months. Notably, caregiver sensitivity moderated several developmental pathways. Findings support a continuous model of early self-regulation development and the ongoing individual-environment interplay in early childhood.  相似文献

Research Findings: This study examined the contribution of teacher-student conflict at kindergarten to the child’s school adjustment in primary school using a Hong Kong sample. It investigated self-regulation as a mediator and parents’ positive relations with others as a moderator in that transition. At Time 1 (T1), kindergarten teachers reported their levels of conflict with individual children (N = 324, 168 girls), whereas children’s self-regulation was assessed with a Head-Toes-Knees-Shoulders Task. Fathers and mothers also rated their positive relations with others. At Time 2 (T2; 8 months later), when children were enrolled in primary school (N = 247, 126 girls), primary school teachers rated how well they adjusted to the new school. Moderated mediation analyses showed that although the direct effect of T1 teacher-student conflict on T2 school adjustment was not significant, the indirect effect of self-regulation was. T1 teacher-student conflicts were negatively related to children’s self-regulation, which in turn predicted subsequent school adjustment. Interestingly, this indirect effect was significant only when parents’ positive relations with others were low rather than high. Practice or Policy: The findings highlight the importance of both a warm and caring relationship in the home and self-regulation to successful school transition.  相似文献

A person-centered approach was used to explore the mediating role of self-regulation between learner typology at age 8 and academic achievement at age 14while controlling for domain-specific achievement in a longitudinal sample of 113 children born to adolescent mothers. Children were classified into one of 5 learner typologies at age 8based on interactive patterns of intellectual, achievement, and adaptive abilities. Typology classification explained significant variance in both reading and mathematics achievement at age 14. A bootstrapping approach confirmed that self-regulation mediated the relationship between typology and reading and mathematical achievement for children from all typologies except those classified as Cognitively and Adaptively Challenged. Implications of person-centered approaches for understanding processes involved with achievement are discussed.  相似文献

Research Findings: This study investigated the long-term interrelations among children’s language competencies, their home literacy environment (HLE), and 3 aspects of socioemotional development from ages 3 to 8, controlling for characteristics of the child and family. For this sample of 547 typically developing German children, parents and teachers reported on cooperative behavior, physical aggression, and emotional self-regulation. Language was assessed using established test instruments. HLE was operationalized by the number of books in the household, the frequency of shared book reading, and an observation during shared book reading. Path analyses supported effects of language and HLE at age 3 on all 3 indicators of socioemotional development over the 5-year period. An additional mediational analysis revealed different patterns of results depending on the aspect of socioemotional competency under study. Although the effect of early language and HLE at age 3 on cooperative and (low) aggressive behavior at age 8 was partially mediated by language at age 5, children’s early language at age 3 was the best predictor of the development of emotional self-regulation. Practice or Policy: Findings identify a rich HLE and proper language skills as protective factors for socioemotional development in not-at-risk children; these factors should be further established in social skills training.  相似文献

Very preterm birth is associated with attention deficits that interfere with academic performance. A better understanding of attention processes is necessary to support very preterm born children. This study examined voluntary and involuntary attentional control in very preterm born adolescents by measuring saccadic eye movements. Additionally, these control processes were related to symptoms of inattention, intelligence, and academic performance. Participants included 47 very preterm and 61 full-term born 13-years-old adolescents. Oculomotor control was assessed using the antisaccade and oculomotor capture paradigm. Very preterm born adolescents showed deficits in antisaccade but not in oculomotor capture performance, indicating impairments in voluntary but not involuntary attentional control. These impairments mediated the relation between very preterm birth and inattention, intelligence, and academic performance.  相似文献
