Previous research has identified a negative correlation between developmental outcomes and length of early intervention programs. In the present investigation, these counterintuitive findings were examined on a sample of “at risk” children who had received a home-based infant development program and who had been enrolled at different age levels. Findings indicated that treatment length was negatively, but not significantly, correlated with developmental outcome. In addition, start age was found to be significantly negatively correlated with outcome, suggesting that certain developmental indices may decrease over time for certain populations. When the regression of time with start age was taken into account in the analyses, large and reliable treatment effects were observed at all start age levels. Results are discussed with respect to future research endeavors. 相似文献

Links between parental knowledge and adolescent delinquent behavior were tested for correlated rates of developmental change and reciprocal associations. For 4 years beginning at age 14, adolescents (N = 396) reported on their delinquent behavior and on their parents' knowledge of their whereabouts and activities. Parents completed measures of their adolescents' delinquent behavior. Knowledge was negatively correlated with delinquent behaviors at baseline, and increases over time in knowledge were negatively correlated with increases in parent-reported delinquent behavior. Reciprocal associations indicate that low levels of parental knowledge predict increases in delinquent behavior and that high levels of delinquent behavior predict decreases in knowledge. Discussion considers both youth-driven and parent-driven processes that may account for the correlated developmental changes and reciprocal associations. 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

Developmental psychophysiologists have long been interested in a means for evaluating infants at risk for cognitive disabilities. The current research addressed the utility of a noninvasive measure of cardiac vagal tone in predicting developmental outcome. At 40 weeks conceptional age, 3 min of resting EKG were recorded from 80 infants. Four groups of infants were evaluated: prematures who had no medical complications in the postnatal period; prematures who experienced respiratory distress syndrome during the postnatal period; term infants who experienced birth asphyxia during labor and/or postdelivery; and healthy term infants. The mental scale of the Bayley Scales of Mental Development was administered at 8 and 12 months conceptional age. Heart period data were analyzed to derive mean heart period, heart period variability, and estimates of vagal tone for each subject. Analyses of the relationship between the heart period variables and 8- and 12-month outcome (i.e., Bayley Scales) indicated that infants with high vagal tone at 40 weeks conceptional age always had positive developmental outcome at both eight and 12 months of age. Infants with low vagal tone had varied outcomes. Measures of medical complications and other measures of heart period variability were not related to developmental outcome. The results suggest that measurement of cardiac vagal tone may provide an important means for assessing risk in birth stressed populations. 相似文献

The present study documented later developmental outcome in a group of 29 failure-to-thrive (FTT) infants who received extended hospitalization in infancy as an intervention for their growth failure. All infants were seen at approximately 3 years of age and were given standardized assessments of intellectual and physical development. A standard interview documented demographic variables, health problems, placements subsequent to hospitalization and additional psychological and medical treatment. Infants were divided into three groups dependent on medical and treatment factors. Means and percentages of occurrence of outcome variables were compared through either one-way ANOVAS or single sample chi-square tests with post hoc analyses. Correlational analyses were used to understand the relationships between outcome and relevant demographic, medical, and treatment variables. In general, the infants manifest persistent intellectual delays at follow-up despite maintenance of weight gains achieved during early hospitalization. More than half the group suffered from chronic health problems. A large percentage of infants had been removed from parental custody at the time of follow-up. Several demographic, medical, and treatment factors bore moderate relationships to developmental outcome. Infants who achieved more optimal growth tended to be full-term at birth, later born and without a question of physical abuse in their social histories. Intellectual functioning was related only to parental and caretaker socioeconomic status. Infants placed in foster care were unlikely to return to their families of origin. The findings suggest the need for further investigation into the determinants and outcome of extended hospitalization as a treatment for FTT. 相似文献

As part of a research project investigating therapist/counsellor orientation and the therapeutic alliance with anorexic or bulimic clients, data was collected not only on therapist orientation but also on training, supervision and personal therapy of the counsellors. While no significant correlation was found between length of training or supervision and the therapeutic alliance score, there was a significant negative correlation between the amount of personal therapy the counsellors had had and the measure of the therapeutic alliance achieved with their clients. Further investigation produced other studies on personal therapy and effectiveness of counselling, in which at best no positive correlation was found between personal therapy and outcome, and at worst, personal therapy was negatively correlated with outcome.These research findings challenge the assumption often made that personal therapy is a desirable if not essential aspect of counsellor training. The arguments for and against personal therapy being included in the training of counsellors are discussed. 相似文献

The relationship between state anxiety and free recall was examined in 74 elderly community‐dwelling adults who had completed a memory improvement program. State anxiety (as measured by the state version of the State Trait Anxiety Inventory) was a significant predictor of recall performance after accounting for age, vocabulary, and study time. State anxiety and age were negatively associated with performance scores, whereas study time and vocabulary were both positively correlated. The evidence suggests that state anxiety should be considered a potential source of variation in verbal learning studies with older adults. The implications of these findings for future research are discussed. 相似文献

Toddlers' acquisition of the Novel Name–Nameless Category (N3C) principle was examined to investigate the developmental lexical principles framework and the applicability of the specificity hypothesis to relations involving lexical principles. In Study 1, we assessed the ability of 32 children between the ages of 16 and 20 months to use the N3C principle (operationally defined as the ability to fast map). As predicted, only some of the children could fast map. This finding provided evidence for a crucial tenet of the developmental lexical principles framewor: Some lexical principles are not available at the start of language acquisition. Children who had acquired the N3C principle also had significantly larger vocabularies and were significantly more likely to demonstrate 2-category exhaustive sorting abilities than children who had not acquired the principle. The 2 groups of children did not differ in either age or object permanence abilities. The 16 children who could not fast map were followed longitudinally until they attained a vocabulary spurt; at that time, their ability to fast map was retested (Study 2). Results provided a longitudinal replication of the findings of Study 1. Implications of these findings for both the developmental lexical principles framework and the specificity hypothesis are discussed. 相似文献

A model of risk potential for developmental outcome was created based on cardiac, medical, surgical, and family-stress factors in 31 children with transposition of the great arteries who had undergone reparative open heart surgery utilizing cardiopulmonary bypass during infancy. Impact of these potential risk factors was assessed by 4 current neurologic measures (neurologic anatomic abnormalities, functional impairment, electroencephalograph [EEG], and Pattern Visual Evoked Potential [PVEP]) and 4 psychologic measures (IQ, achievement, perceptual-motor function, and behavior). Results indicated that adverse developmental outcome was significantly associated with the following medical risk variables: failure of palliative surgery to alleviate hypoxia, prolonged hypoxia, growth failure, congestive heart failure, absence of ameliorating shunting heart defects, stroke, and CNS infection; and two psychosocial moderator variables: socioeconomic status and current life stress. Analysis of a "cumulative risk score" indicated significantly higher risk scores in children with abnormal EEGs, PVEPs, and neurologic examinations. The cumulative risk score highly correlated with composite neurologic outcome (r = .62), IQ (r = -.66), achievement (r = -.60), and perceptual-motor function (r = -.48). While overall outcome was favorable for children with TGA who experienced a single risk event, outcome was compromised if multiple risk factors occurred. 相似文献

This investigation examined the “earlier one starts an intervention, the better” hypothesis for handicapped preschoolers. Posttest performances of handicapped preschoolers on the Bayley Mental Development Index (MDI) and the Bayley Psychomotor Development Index (PDI) were evaluated in relation to the age at which the intervention began, the length of intervention, and Bayley pretest scores. Results indicated that age at start and length of treatment bore little relation to treatment outcomes. However, Bayley pretest scores correlated moderately with posttest scores. Possible explanations are discussed. 相似文献

This paper explores how starting school at a younger age affects the developmental score gaps between relatively advantaged and disadvantaged children. While previous findings suggest that delaying school entry may improve school readiness, less is known about whether it has differential effects for advantaged and disadvantaged children. For disadvantaged children, starting school early may be a better alternative to staying at home for longer as school provides a more stable and educational environment than the family home, overcompensating for the penalties of starting school early. This may be less applicable to relatively advantaged children who generally have greater access to resources in the home and who are more likely to utilise formal pre-school services. We use the Longitudinal Study of Australian Children to investigate if there is support for this hypothesis. The endogeneity of school starting age is addressed using the regression discontinuity design. We find that an early school start generally improves children’s cognitive skills, which is even more pronounced for disadvantaged children. In contrast, an early school start tends to negatively affect children’s non-cognitive skills with both advantaged and disadvantaged children affected in similar ways. Thus, our findings suggest that an earlier school entry may narrow the gaps in cognitive skills, whereas the gaps in non-cognitive skills are not affected by the school starting age. 相似文献

This paper reports on the progress made by a small group of fourteen 11‐year‐old children who had been originally identified as being precocious readers before they started primary school at the age of five. The data enable comparisons to be made with the performance of the children when they were younger so that a six‐year longitudinal analysis can be made. The children who began school as precocious readers continued to make progress in reading accuracy, rate and comprehension, thereby maintaining their superior performance relative to a comparison group. However, their progress appeared to follow the same developmental trajectory as that of the comparison group. Measures of phonological awareness showed that there are long‐term, stable individual differences that correlated with all measures of reading. The children who were reading precociously early showed significantly higher levels of phonological awareness than the comparison children. In addition, they showed the same levels of performance on this task as a further group of high achieving young adults. A positive effect of being able to read at precociously early age was identified in the significantly higher levels of receptive vocabulary found amongst these children. The analyses indicated that rises in receptive vocabulary resulted from reading performance rather than the other way round. 相似文献

Cognitive performance and development is negatively correlated with fixation duration patterns during infancy, and evidence suggests that long-looking infants may process visual information more slowly than short-looking infants. 3 experiments described here tested the possibility that these differences may be due to differential sensitivity to global and local visual information. Infants were administered discrimination and generalization tasks involving global and local information at varying levels of familiarization time. Results indicated that 4-month-olds process visual information in a global-to-local sequence. Both long- and short-looking infants were sensitive to both types of information, although long lookers required additional familiarization time to match the performance of short lookers. Finally, apparent "generalization" of global information at brief familiarization levels was traced to insensitivity to local stimulus properties. The results do not support the hypothesis that long- and short-looking infants are differentially sensitive to global versus local visual information at 4 months of age. 相似文献

The effectiveness of early intervention programs for children with developmental disabilities and for children at biologic risk was reviewed and analyzed. A general pattern indicating important effects of early intervention programs was noted, with effect sizes averaging between one-half and three-quarters of a standard deviation. The ability of early intervention programs to minimize declines in development was identified as a significant outcome. The effects of specific program features--age of start and family involvement--were selected for more detailed examination, and the moderating influence of the levels of severity of children's disabilities was also analyzed. Future directions for improving the effectiveness of early intervention include using the emerging knowledge of biobehavioral and child development research, as well as enhancing children's social competence. 相似文献

This commentary discusses the program of research carried out by the Utah State Early Intervention Research Institute (EIRI) in the context of the characteristics associated with second generation research in early intervention. Specifically, the series of EIRI research studies focused on the three program features of age of start, intensity of intervention, and parent participation. This commentary provides an evaluation of these program features in terms of scientific quality, specificity of the research, and consistency with contemporary developmental/ecological approaches. Directions for future research are noted, and these include: greater emphasis on establishing expectations for outcomes derived from developmental models, multisite studies to permit more effective specificity analyses, and emphasis on identifying the characteristics of children and families who are at greatest risk of not responding to prevailing early intervention services and supports. 相似文献

Children's understanding of moral emotions 总被引：4，自引：1，他引：4
4-8-year-old children's attributions of emotion to a story figure who violated a moral rule were studied in a series of experiments. Most 4-year-olds judged a wrongdoer to experience positive emotions, focusing their justifications on the successful outcome of his action, whereas almost all 8-year-olds attributed negative feelings, focusing on the moral value of the wrongdoer's action. A developmental trend from outcome-oriented toward morally oriented emotion attributions was also observed in children's judgments of the feelings of a story character who had resisted temptation. When morally evaluating a wrongdoer, only children above the age of 6 years took emotional reactions into account, judging a "happy" wrongdoer to be worse than a "sorry" one. 4- and 5-year-olds attributed positive emotions to a wrongdoer even if his transgression was severe and if he did not gain any material profit from it. However, they did not expect a person (even an ill-motivated one) to feel good if he or she unintentionally harmed another person or merely observed someone being hurt. These results are discussed in relation to recent research on children's developing conceptions of emotion and on the early development of moral understanding. 相似文献

Reproductive, perinatal, and environmental factors as predictors of the cognitive and language development of preterm and full-term infants 总被引：2，自引：0，他引：2
L S Siegel 《Child development》1982,53(4):963-973
The accuracy of a risk index based on reproductive and demographic factors to predict subsequent development was tested with 51 full-term and 53 preterm (birth weight less than 1,501 grams) infants. Stanford-Binet IQ and Reynell Language Expression and Comprehension at 3 years were significantly predicted by this risk index. Socioeconomic status, birth order, and, for the preterm group, severity of illness in the perinatal period were the most significant predictors of developmental outcome. The Home Observation for Measurement of the Environment (HOME) scores were significantly correlated, independently of SES and developmental level, with the 3-year Reynell and Stanford-Binet scores for the preterm, but not the full-term, group. Children who were classified as being at risk at 12 months but who had scores in the normal range at 3 years came from families with significantly higher scores on the HOME scale. Children not detected as being at risk in infancy but whose development was delayed at 3 years came from families with lower scores on the HOME scale. The combination system of perinatal, reproductive, and environmental variables allows the detection of infants at risk for subsequent developmental problems. 相似文献
