A close association between affective expression and cognitive development was demonstrated in a longitudinal study of 14 Down's syndrome infants. It was found that the Down's syndrome infants laughed to groups of stimulus items in the same order as did previous samples of normal infants. Although the process was delayed by several months, the retarded babies too laughed first at physically intrusive items and only later to items calling for greater cognitive sophistication. In addition, cognitive developmental status, assessed by the Bayley and Uzgiris-Hunt scales, paralleled and was predicted by the level of affective development. Predictive and concurrent correlations between Bayley mental scores and various indices of affectivity ranged from .68 to .92. There was striking individual consistency across affective, mental, and motor measures, suggesting the organized nature of retarded development. Finally, since Down's syndrome infants frequently smiled under conditions when normal babies would laugh, a role for tension production, in addition to cognitive factors, was suggested in accounting for the behavior of these infants. 相似文献

In a study with 17 Down's syndrome infants, the older infants (mean age = 20 months, 6 days) responded to the regular reappearance of a squeaky doll with significantly more affective behavior than did younger infants (mean age = 9 months, 24 days). When the 10 younger infants were included in a longitudinal study of their responses to this same event, the onset of affective behavior was significantly correlated with the mental development index of the Bayley Scales of Infant Development, and was also associated with some aspects of temperament as measured by the Carey Survey of Temperamental Characteristics: these aspects were poor adaptability to change and a low tendency to approach new situations. 相似文献

A study of auditory preferences in nonhandicapped infants and infants with Down's syndrome 总被引：1，自引：1，他引：1
11 infants with Down's syndrome (MA 9.2 months, CA 12.7 months) and 10 of 11 nonhandicapped infants (MA 9.6 months, CA 9.3 months) demonstrated that they could operate an automated device which enabled them to choose to listen to 1 of a pair of auditory signals. All subjects showed preferential responding. Both groups of infants showed a significant preference for nursery rhymes sung by a female voice rather than played on musical instruments. The infants with Down's syndrome had much longer response durations for the more complex auditory stimuli. The apparatus provides a useful technique for studying language development in both normal and abnormal populations. 相似文献

This study relates parenting of 3-month-old children to children's self-recognition and self-regulation at 18 to 20 months. As hypothesized, observational data revealed differences in the sociocultural orientations of the 3 cultural samples' parenting styles and in toddlers' development of self-recognition and self-regulation. Children of Cameroonian Nso farmers who experience a proximal parenting style develop self-regulation earlier, children of Greek urban middle-class families who experience a distal parenting style develop self-recognition earlier, and children of Costa Rican middle-class families who experience aspects of both distal and proximal parenting styles fall between the other 2 groups on both self-regulation and self-recognition. Results are discussed with respect to their implications for culturally informed developmental pathways. 相似文献

The development of developmentally delayed young children is similar to that of normal children in sequence and organization. The hypothesis of this research was that delayed children do differ from the norm when tasks involve discerning nuances, balancing competing stimuli, or acquiring and retaining selected information. Using a videotaped free-play situation, we examined attention deployment behaviors of 3 groups: normally developing (ND), Down syndrome (DS), and developmentally delayed with uncertain etiology (UE). Gesell DQ scores ranged from 50 to 75 in the latter 2 samples. In Study 1, infants had developmental ages of 12-24 months. The UE subjects spent less time engaged with toys than ND or DS subjects, and both delayed groups had less simultaneous appraisal of the environment, more time unoccupied in any way, and more throwing behavior than the ND group. In Study 2, at the 22-30-month developmental age range, DS and UE subjects had patterns of play that included many primitive activities such as banging and mouthing. Taken together, the results show reductions in ongoing acquisition and elaboration of information during play; these in turn may have significant developmental ramifications. 相似文献

INFANTS and young children with Down syndrome who were living at home and attending exemplary early intervention programs were assessed by trained examiners in the five domains of the Battelle Developmental Inventory. Data was compared to the 50th percentile attainment and found that infants and young children with Down syndrome are more similar to other children in Personal Social and Adaptive Domains and less similar in Communication and Cognitive Domains. These differences begin to show more dramatically as the child reaches the age of 36 months. The older the child the greater the measured differences. Documenting and understanding this uneven developmental path is significant in program planning. 相似文献

Information collected in Sheffield during the last 10 years indicates that the growing number of children with Down's syndrome who begin their school life in the mainstream drift towards special schools as they grow older. At every change of school some children move from ordinary schools into schools for children with varying degrees of learning difficulty. While all six pupils receiving education at pre-school stage were integrated only one child in the 13–16 years age range was still in the mainstream. Why should this be? Dr Phil Budgell, educational psychologist with Sheffield School Psychological Service, suggests some possible answers. 相似文献

Developmental education for parents of delayed infants: effects on parental motivation and children's development 总被引：1，自引：0，他引：1
This study compared the effectiveness of developmental education for parents with parent education in child management and with a no-education control condition in motivating parents to participate in home treatment programs for developmentally delayed infants. 39 delayed infants, matched for age and severity of delay, and their families were randomly assigned to the 3 treatment groups. The subsequent differential effectiveness of home treatment programs, in terms of the infants' developmental gains, was then examined. Results indicated that the children in the developmental education group gained a greater number of skills, and their parents participated more in the assigned home treatment programs than did parents in the other 2 groups. At follow-up approximately 1 year later, parents who received developmental education continued to participate more than the other parents in their child's treatment program. Developmental education appears to enable parents to discriminate small developmental gains, facilitating the intrinsic motivation involved in working with their children. 相似文献

Developmental Outcome of Minority Infants: A Process-oriented Look into Our Beginnings 总被引：2，自引：0，他引：2

This article reviews the literature on the development of children of minority status from birth to 3 years of age (infants). 5 major sources of influence on the developmental outcome of minority infants are proposed: cultural beliefs and caregiving practices, health status and health care practices, family structure and characteristics, socioeconomic factors, and biological factors. It is suggested that differences exist between minority and Anglo families in their developmental goals and interactions during the infancy period. The health status of some minority groups places these infants in an at-risk category for neurodevelopmental problems. The family context is characterized by younger mothers, a higher percentage of single heads of households, but also large, extended families. Socioeconomic factors have a pervasive influence on both infants and parents, and the contribution of biological factors is suggested but poorly understood. It is concluded that these factors act synergistically to place these infants in alternative (not necessarily deviant) developmental pathways, or in "at-risk" categories for neurodevelopmental problems, while canalization processes are operating to insure that major developmental milestones are achieved. 相似文献

This article presents results from an interview study of 45 parents/caregivers (representing 27 families) whose infants were correctly identified as deaf during the first phase of the implementation of the national universal Newborn Hearing Screening Programme in England. Average age of children when parents were interviewed was 25 weeks. Two issues are explored: (a) how parents talk about significance of knowing early that their child is deaf and (b) parents' expectations of their child's development in light of early identification. Although results demonstrate clear support from parents' perspective of knowing early, they also identify the psychological complexities of recognizing both the grief and reassurance that early knowledge brings; the risks of early knowledge-inducing timetables of expectations that create distress when not met speedily; the extent to which parental models of the developmental advantages of early identification are underpinned by notions of normal speech and the possibility of being like hearing children; and the pervasiveness of deficit and illness models associated with having identified deafness early. Implications for parental support and professional responses are also discussed. 相似文献

Researchers studying social-emotional development have argued that primary attachment relationships, established by the end of the first year of life, are important organizing factors that influence the trajectory of development throughout childhood. Central to this argument is a dimension of "attachment security," along which attachments differ. For normally developing infants and toddlers, attachment security is assessed using the Ainsworth Strange Situation. However, it is not clear that this procedure is appropriate for evaluating attachment security in atypical populations. In this report, 3 samples of children with Down Syndrome (total N = 138) were assessed using the Strange Situation. The procedures were scored according to traditional protocols. Although the 3 samples differed with respect to chronological and developmental age, they showed basic similarity with respect to attachment variables. However, developmentally younger children were more difficult to classify using the standard scoring rules. Scores and classifications for the sample were compared to scores from a sample of normally developing children tested at about 12 months of age. Significant differences with respect to the distributions of cases to classification categories and with respect to the interactive scale scores suggest that the Strange Situation may be measuring different aspects of behavior for children with Down Syndrome, even when they are tested at similar developmental age levels. 相似文献

The human figure drawings of 18 children with mild learning difficulties (MLD) were compared with those of 18 children with the same chronological age (mean 10 years, 4 months) and those of 18 children with the same mental age (mean 6 years, 0 months). The MLD children's drawings were similar to those of the 6‐year‐olds in terms of the number of developmental items they displayed; both these groups scored significantly lower than the 10‐year‐olds. Teachers could easily distinguish the 10‐year‐olds’ figures, but not those drawn by the MLD children and the 6‐year‐olds; they routinely confused the two. These findings suggest that, although their development is slower, MLD children follow a normal rather than a deviant developmental pattern. 相似文献

This study compared the relative contributions of growing body dimensions, age, and walking experience in the development of walking skill in 9- to 17-month-old infants (N = 210), 5-6-year old kindergartners (N = 15), and college students (N = 13). Kinematic measures derived from participants' footprints showed characteristic improvements in walking skill. As children became bigger, older, and more experienced, their steps became longer, narrower, straighter, and more consistent. Improvements reflected a narrowing base of support and increasing control over the path of progression. Although both infants' age and the duration of their walking experience contributed to improvements in walking skill, experience was the stronger predictor. This finding suggests that practice is the more important developmental factor for helping infants to conquer their weak muscles and precarious balance. 相似文献

Data on the placements of over 3,000 children with Down's syndrome (born between 1980 and 1992) were collected from 94 areas around the country, over the 12 year period studied. Analysis showed an increase in the proportion of children attending mainstream schools, with wide local variations. Very small numbers of children had mixed placements (part-time mainstream/special school) and placements in specially resourced units. Changes in school type occurred from mainstream to special school, typically at around 8 or 9 and again at 11 to 12 years. There was a disproportionate number of boys with Down's syndrome in special schools, apparently because more boys than girls entered special schools at 5 or 6 years old. 相似文献

This study examined coping competence in three groups of young children: at- risk, developmentally delayed, and typically developing. The Early Coping Inventory was adapted to rate coping behaviors objectively in 114 infants and toddlers (mean age = 22 months). Typically developing children were rated as significantly more effective than children at-risk and children with developmental delays; Children at-risk received significantly higher coping ratings than did children with developmental delays. A significant main effect due to ethnicity and a developmental group by ethnicity interaction also emerged. Post hoc analyses suggested that ethnicity differences were-limited to the at-risk and developmentally delayed groups, Also, ethnicity differences in children within the at-risk group served as an informative source for understanding the developmental group by ethnicity interaction. These findings' contribution to the literature on socio-emotional competence, early childhood assessment, and prevention/intervention policies for young children are discussed. 相似文献

The relations among age appearance, facial attractiveness, and adult expectations of the developmental maturity of infants were examined in 3 studies. In Study 1, a relation was demonstrated between ratings of the attractiveness (77 judges) and age appearance (53 judges) of 6-month-olds: less attractive infants were judged to be older than their attractive age-mates. In Study 2, 75 parents judged the specific developmental abilities of 6-month-old infants and estimated the age of the babies. Parents overestimated both the age and the developmental abilities of the unattractive infants. Furthermore, ability estimates for the unattractive infants were significantly higher than judgments of the typical abilities of 6-month-olds made by another group of 35 parents. Finally, the results of Study 2 were replicated in Study 3 conducted with 348 mothers. It was also demonstrated in Study 3 that, although mothers expected unattractive infants to be capable of more specific developmental skills, they nevertheless rated the general competence of the unattractive infants to be lower than that of attractive infants. Specious contradictions in the attractiveness and age appearance literatures are resolved by these results: age appearance seems to function as an informational cue with respect to specific age-appropriate abilities, whereas attractiveness elicits evaluative attributions of general competence. Both types of information conveyed in faces may have important implications for adult evaluations of infants and older children. 相似文献

This Monograph presents the results of a nonexperimental, longitudinal investigation of developmental change in 190 infants and their families after 1 year of early intervention services. The Early Intervention Collaborative Study (EICS), conducted in association with 29 community-based programs in Massachusetts and New Hampshire, was designed to assess correlates of adaptation in young children with disabilities and their families over time, to inform social policy by analyzing the influences of family ecology and formal services on child and family outcomes, and to generate conceptual models to guide further investigation. The study sample (mean age at entry = 10.6 months) includes 54 children with Down syndrome, 77 with motor impairment, and 59 with developmental delays of uncertain etiology. Data were collected during two home visits (within 6 weeks of program entry and 12 months later) and included formal child assessments, observations of mother-child interaction, maternal interviews, and questionnaires completed independently by both parents as well as monthly service data collected from service providers. Child and family functioning varied considerably. Developmental change in the children (psychomotor abilities, adaptive behavior, spontaneous play, and child-mother interaction skills) was influenced to some extent by gestational age and health characteristics, but the strongest predictor of change was the relative severity of the child's psychomotor impairment at study entry. Families demonstrated generally positive and stable adaptation (in terms of the effect of rearing a child with disabilities on the family, parenting stress, and social support), despite persistent challenges with respect to mother-child interaction and differences in reported stress between mothers and fathers. Documentation of services revealed that early intervention is a complex and multidimensional experience that spans multiple public and private systems. Vulnerable and resilient subgroups within the sample were identified, and different correlates of adaptive change were demonstrated. Results of data analyses suggest new perspectives on the study of early childhood disability. The implications of the findings for developmental theory and social policy are discussed. 相似文献

Assessing potential risks to children who participate in developmental research is a challenging task because children are a heterogeneous population, varying in developmental competencies and in background characteristics. This essay offers a developmental perspective on research risk, emphasizing that children's vulnerability to research risk changes in complex ways: some risks decrease with increasing age, some increase as the child matures, others change in a curvilinear fashion, while some remain essentially stable with development. Because vulnerability in research does not simply decline linearly with age, assessments of research risk must entail multidimensional considerations that vary over developmental time. In a similar manner, individual characteristics of children at any age (e.g., maltreatment, at-risk status, etc.) may also heighten their vulnerability to certain risks which require special consideration by researchers. Finally, this discussion of developmental vulnerability and the principles underlying research ethics suggests that in addition to the conventional risk/benefit analysis, researchers are in an optimal position to establish and maintain standards of decent treatment of children in research that safeguard their rights as research participants. Suggestions for fostering this process in the research community are outlined. 相似文献

The development of social referencing 总被引：6，自引：0，他引：6
The development of social referencing in 40 infants aged 6-9, 10-13, and 14-22 months was investigated in this study. Social referencing was defined broadly to include children's looks toward parents, their instrumental toy behaviors, affective expressions, and other behaviors toward parents. Children's looks at parents were more selective with increasing age, with older infants preferring to look directly at their parents' faces and younger infants showing no preference for looks to faces over looks elsewhere at the parent. Younger infants looked most often when their parents expressed positive affect, whereas older infants looked most often when parents displayed fearful reactions toward a stimulus. Evidence of a behavioral regulatory effect on instrumental toy behaviors was found only among infants 10-13 months of age. However, only infants older than 14 months of age inhibited touching the toy until after referencing the parent. On some measures these older infants showed a preference for toys associated with fearful messages. Affective expressions were in line with positive and negative behavior toward toys. No support for mood modification or simple imitation as explanations for the effects was found. Results indicated that the looking behavior of younger children may function differently than that of older children, and that social referencing involves a number of component skills that develop during the end of the first year and throughout the second year of life. 相似文献
