A test of visual novelty preference, the Fagan Test of Infant Intelligence, was administered to a group of 113 full-term infants from the Colorado Adoption Project at 5 and 7 months of age. The infants were followed longitudinally and the Bayley scales were administered at 12 and 24 months, the Sequenced Inventory of Communication Development at 24 and 36 months, and the Stanford-Binet and the Colorado Specific Cognitive Abilities Test at 36 months. 1 novelty preference score was obtained for each infant by averaging across the 2 test ages. Novelty preference correlated significantly with 36-month Binet IQ, the first unrotated principle component from the cognitive battery, and the 24-month Bayley MDI score. Novelty preference was also compared to specific abilities at all 3 follow-up ages; all of the specific abilities were significantly related to novelty preference, with the exceptions of 12- and 24-month Imitation and 36-month Perceptual Speed. Partial correlations suggest that novelty preference predicts language and memory independent of IQ. Overall, the results indicate that novelty preference during the first year of life not only predicts later IQ but may also reflect specific cognitive processes.  相似文献

Attention is construed as multicomponential, but the roles of its distinct subfunctions in shaping the broader developing cognitive landscape are poorly understood. The current study assessed 3‐ to 6‐year‐olds (N = 83) to: (a) trace developmental trajectories of attentional processes and their structure in early childhood and (b) measure the impact of distinct attention subfunctions on concurrent and longitudinal abilities related to literacy and numeracy. Distinct trajectories across attention measures revealed the emergence of 2 attentional factors, encompassing “executive” and “sustained–selective” processes. Executive attention predicted concurrent abilities across domains at Time 1, whereas sustained–selective attention predicted basic numeracy 1 year later. These concurrent and longitudinal constraints cast a broader light on the unfolding relations between domain‐general and domain‐specific processes over early childhood.  相似文献

This longitudinal study evaluated the extent to which maternal responsiveness across early childhood and children's cognitive skills predicted children's 8-year decoding and reading comprehension skills for children who varied in biological risk (term, n = 83; preterm, n = 155). Patterns of maternal responsiveness during infancy (6, 12, and 24 months) and preschool (3 and 4 years) revealed 4 maternal clusters that varied in consistency and level of maternal responsiveness. Although not predictive of decoding skills, the interaction between children's 4-year cognitive ability and maternal responsiveness cluster predicted children's reading comprehension skills at 8 years of age, regardless of risk. Although consistently high levels of maternal responsive parenting across early childhood related to literacy outcomes for all children in the study, responsive parenting had a stronger relation to later reading comprehension skills for children with lower cognitive abilities, particularly when mothers demonstrated high responsiveness in children's infancy.  相似文献

A group of 46 full-term and 54 high-risk preterm (less than 1,500 grams birthweight) infants were tested at 6, 7, and/or 8 months of age (corrected age for preterms) on a battery of problems assessing visual recognition memory and tactual-visual cross-modal transfer. At all 3 ages, scores obtained on aggregates of 6-11 problems in the battery significantly predicted 3-year Stanford-Binet IQ: correlations ranged from r = .37 to r = .63, and clustered between r = .50 and r = .60. When aggregates from 2 or 3 ages were used as predictors, multiple correlations were as high as R = .60 and R = .70. Cutoffs for predicting children at risk for mental retardation (IQ less than 70) or cognitive delay (IQ less than 85) showed reasonable sensitivity and specificity, although low scores were poor at detecting IQs less than 70. The internal consistency of composites, indexed by alpha coefficients, was unexpectedly low, primarily because the problems shared little variance. However, stability coefficients between assessments as much as 1 and 2 months apart were moderate in magnitude, ranging from r = .30 to r = .50. Considering the high degree of predictive validity, the stability figures appear to be better estimates of reliability for these measures than are indices of internal consistency. The relations reported here were similar for both full-terms and preterms.  相似文献

Early differences in family SES, child language production, and IQ were related to outcomes in early elementary school in the present prospective, 10-year longitudinal study. In a prior study of family interactional variables associated with language learning, major differences in parenting (i.e., time, attention, and talking) were found to be associated with differences in child productive vocabulary between 7 to 36 months of age, and child IQ, favoring higher-SES parents. Lower-SES children were exposed less often than higher-SES children to diverse vocabulary through their parents' attention and talking, and they were prohibited from talking more often. In the current study, 32 children involved in the earlier study were repeatedly assessed between 5 to 10 years of age, while in kindergarten through third grade. Results indicated that SES-related differences in child language prior to school were predictive of subsequent verbal ability, receptive and spoken language, and academic achievement assesed on standardized tests in kindergarten through grade 3. However, none of the predictor variables were related to direct measures of elementary schooling. When combined with a composite SES indicator, early child language production significantly increased the variance accounted for in the prediction of elementary language and academic competencies in each subsequent year in elementary school. Implications are discussed in terms of the stability of performance on language and academic performance measures of children who entered school with different early language learning experiences, and the need to consider early home- and school-based intervention designed to prevent or ameliorate these trends.  相似文献

In a longitudinal genetic study we explored which factors underlie stability in verbal and nonverbal abilities, and the extent to which the association between these abilities becomes stronger as children grow older. Measures of verbal and nonverbal IQ were collected in Dutch twin pairs at age 5, 7, 10, 12 and 18 years. The stability of both verbal and nonverbal abilities was high, with correlations over time varying from .47 for the 13-year time interval up to .80 for shorter time intervals. Structural equation modeling showed increasing heritability with age, from 48% (verbal) and 64% (nonverbal) at age 5 to 84% and 74% at age 18. Genetic influences seemed to be the driving force behind stability. Stability in nonverbal ability was entirely explained by genes. Continuity in verbal abilities was explained by genetic and shared environmental effects. The overlap between verbal and nonverbal abilities was fully accounted for by genes influencing both abilities. The genetic correlation between verbal and nonverbal IQ increased from .62 in early childhood to .73 in young adulthood.  相似文献

This study examined the extent to which memory and processing speed accounted for relations we had found earlier between infant information processing and childhood IQ. The measures of speed and memory were obtained when the children were 11 years of age using paper-and-pencil tasks and an extensive battery of computer-administered tasks. The relations of 7 month visual recognition memory and 1 years cross-modal transfer to 11 years IQ were both substantially reduced with statistical control of factors dericed from these measures. These results suggest that speed and memory underlie some of the infant-childhood continuities in cognition. Path and stuctural equation modeling indicated that the significant pathways from 7 month visual recognition memory to 11 year IQ were nboth directr and indirect, the indirect paths going through memory and speed.  相似文献

Intelligence scores of children in a longitudinal study were assessed at 4 and 13 years and related to social and family risk factors. A multiple environmental risk score was calculated for each child by counting the number of high-risk conditions from 10 risk factors: mother's behavior, mother's developmental beliefs, mother's anxiety, mother's mental health, mother's educational attainment, family social support, family size, major stressful life events, occupation of head of household, and disadvantaged minority status. Multiple risk scores explained one-third to one-half of IQ variance at 4 and 13 years. The stability between 4- and 13-year environmental risk scores ( r = .77) was not less than the stability between 4- and 13-year IQ scores ( r = .72). Effects remained after SES and race, or maternal IQ, were partialled; multiple risk was important in longitudinal prediction, even after prior measurement of child IQ was accounted for; the pattern of risk was less important than the total amount of risk present in the child's context.  相似文献

Whether or not more effective schools can successfully mitigate the impacts of early disadvantage upon educational attainment remains uncertain. We investigated 2,664 children aged 6–11 years and measured their academic skills in English and maths along with self-regulation at 6, 7, and 11. Experiencing multiple disadvantages before age 5 strongly impaired later self-regulation and academic attainment. However, attending a more academically effective primary school for just a single year was found to partially protect all outcomes at age 6. In addition, more academically effective primary schools significantly lessened the extent to which earlier abilities in reading, writing, and self-regulation predicted these same abilities at age 11. Thus, although attending a more academically effective primary school does not eliminate the adverse impacts of multiple disadvantage experienced at a younger age, it can mitigate them by promoting better academic attainment and self-regulation up to age 11 for children who had experienced more disadvantages.  相似文献

The reciprocal effects among cognitive-behavioral, environmental, and biological influences on clinic-referred children's ( N = 64; 34 boys; M age 12.71 years) short-term psychological and psychiatric adjustment were studied. At clinic intake and 6 months later, standardized measures of adjustment and control-related beliefs were assessed. Before and after conflict-oriented parent-child interaction tasks the children's saliva was sampled. Adrenocortical responses (i.e., increases in salivary cortisol) to the social conflict task predicted children's internalizing problem behaviors and anxiety disorders at follow-up. Consistently high adrenocortical reactivity at intake and follow-up was associated with deflated social competence over the 6-month period. Also, specific patterns of discontinuity in children's internalizing behavior problems predicted individual differences in their subsequent adrenocortical responsiveness. Specifically, rising behavior problem levels across time predicted higher and declining behavior problem levels predicted lower adrenocortical reactivity at follow-up. Findings are among the first to suggest links among internalizing behavior problems, adrenocortical responsiveness to social challenge, and clinic-referred children's short-term cognitive-behavioral and emotional adjustment.  相似文献

OBJECTIVE: We investigated the possible reciprocal relationship between victimization experiences and psychological functioning by assessing abuse experiences in childhood, adolescence, and during a 2-month follow-up period. METHOD: At the beginning of the study (Time 1), abuse histories, trauma and depressive symptoms, and interpersonal functioning were assessed in 551 college women. Subsequent victimization experiences and psychological outcomes were assessed at the follow-up (Time 2). RESULTS: Path analyses indicated that verbal abuse by the mother and father were predictive of various psychological outcomes as measured at Time 1 and emerged as the only significant predictors of adolescent dating violence. Adolescent dating violence subsequently predicted the experience of dating violence during the 2-month follow-up period. Paternal physical abuse predicted adolescent sexual victimization which subsequently predicted all symptom measures at Time 1. Conversely, the experience of adolescent physical dating violence was not predictive of any of the symptom measures at Time 1. For those women who experienced dating violence during the follow-up, however, the severity of their abusive experiences was related to both depression and interpersonal problems assessed at Time 2. In comparison, for those women who experienced sexual victimization during the follow-up period, the severity of their abusive experiences was related to trauma symptoms. Interpersonal problems emerged as both an aftereffect of adolescent sexual victimization experience and a predictor of a subsequent sexual victimization experience during the follow-up. CONCLUSIONS: Given that emotional abuse emerged as a predictor of adolescent dating violence and psychological outcomes, researchers and clinicians need to continue to explore this problem. Further, it is important to assess how interpersonal problems contribute to the risk of subsequent sexual victimization and to try to break the cycle between adolescent abuse experiences and subsequent physical and sexual assaults.  相似文献

The WISC and WISC-R protocols of 94 special education students (51 white males, 5 black males, 30 white females, and 8 black females) who tested in the mildly retarded and borderline range of abilities (IQs of 50–78) were examined. Their test performance was then followed longitudinally for two additional WISC and WISC-R assessments. Mean age of subjects was 8 years at Test 1, 10.75 years at Test 2, and 14.9 years at Test 3. As predicted, subjects had lower IQ equivalent scores on Bannatyne's Sequencing Ability category than their IQ equivalent scores on the Verbal Comprehension or Perceptual Organization factors of the WISC and WISC-R for all three testings. Results were interpreted as supporting the notion that mildly retarded children and learning disabled children have qualitatively similar learning patterns.  相似文献

Based on the data of the normative study of the Hong Kong test of specific learning difficulties in reading and writing, and the Test of visual‐perceptual skills (non‐motor)—Revised, 99 children aged between 6 and 10½ years were identified as children with dyslexia out of the normative sample of 690 children. By excluding 12 children known to score below average in IQ, 87 children, including 20 children not tested for IQ, could be regarded as children with dyslexia, yielding a prevalence rate of 12.6% and a boy:girl gender ratio of 1.6 to 1. The figures would become 9.7% and 2.0 to 1 if the 20 children were omitted from computation. However, gender imbalance could not be readily explained by gender differences in reading‐related cognitive abilities, as there were only minor and subtle differences. Regression analyses to evaluate the relative contribution of different cognitive abilities to reading and writing suggested that orthographic knowledge and naming speed were most important among children with dyslexia. Implications of the findings and the need for early intervention are discussed.  相似文献

OBJECTIVE: This project was designed to examine the impact of adolescent mothers' abuse potential on the development of preschool children. The specific aims were to demonstrate relationships between maternal abuse potential and developmental problems in preschool children, to examine these relationships across time, and to determine whether maternal abuse potential predicted developmental delays after controlling for problematic parenting orientations. METHOD: Using a longitudinal design, we examined 146 first time mothers and their children. Maternal abuse potential was assessed when children were 1, 3, and 5 years old; problematic parenting orientation was assessed when the children were 6 months old; and child development (i.e., IQ, adaptive behavior, and behavior problems) was assessed at ages 3 and 5. RESULTS: Regression analyses revealed significant relationships between maternal abuse potential and a variety of developmental problems. Path analyses revealed unidirectional relationships between abuse potential predicting IQ and adaptive behaviors. Further analyses indicated that maternal abuse potential at 1 and 3 years predicted intelligence and adaptive behavior at ages 3 and 5, even when problematic parenting orientation was controlled. In contrast, children's behavioral problems at ages 3 and 5 was better accounted for by problematic parenting orientation than by abuse potential. CONCLUSIONS: The results of this study revealed that developmental delays in children of adolescent are related to abuse potential. Two pathways were found for predicting developmental delays: One pathway linked child abuse potential with IQ and adaptive functioning: the other pathway showed that problematic parenting orientation accounted for the development of emotional and behavioral problems.  相似文献

Around 1980, many perinatal centers began prospective cranial screening of preterm infants using portable ultrasonography at the bedside. This study examined developmental outcome at 1 and 2 years in relation to the presence and severity of neonatal intraventricular hemorrhage (IVH). It varies from earlier reports in the size of the sample, restriction to infants without periventricular leukomalacia (PVL), and an attempt to formulate a predictive model by examining development longitudinally. Parametric and nonparametric analyses demonstrated that IVH related to Bayley mental and motor scores and neurologic ratings at 1 year but not at 2 years. Developmental delay and/or neurologic abnormality were more prevalent in infants with severe IVH but were far from universal. Regression analyses on prediction from neonatal and 1-year performance to 2-year scores revealed significant associations between the 1- and 2-year measures but not the neonatal and outcome measures. A direct insult to the CNS such as IVH thus constitutes only a limited model of risk status.  相似文献

Most previous studies of children with birthweight <750 g have focused on early childhood sequelae. To evaluate later outcomes, a regional sample of 60 <750-g birthweight children was compared at middle school age (M = 11 years) to 55 children with birthweight 750-1,499 g and 49 term controls. The groups were matched on age, gender, and demographic variables at the time of an early-school-age assessment (mean age 7 years). The <750-g birthweight group fared less well at middle school age than the term group on measures of cognitive function, achievement, behavior, and academic performance. In many instances, outcomes were less favorable for the <750-g children than for the 750 to 1,499-g group. Children in the <750-g group who were free of neurosensory disorders and global cognitive impairment performed more poorly on several tests than their term counterparts. Group differences in this subsample on tests of motor skills, math, and the ability to copy and recall a complex drawing remained significant even after controlling for IQ. Disparities between the <750-g and term groups increased with age for some measures. Despite favorable outcomes for many children in the <750-g group, this population is at risk for long-term developmental problems.  相似文献

A number of preterms who had participated in a study of visual recognition memory when they were 6 months of age were seen at older ages to assess the predictive validity of the early visual measures for cognitive outcome. The Bayley scales were administered at 6, 12, and 24 months, the Stanford-Binet at 34 and 40 months, and the WISC-R at 6 years. Novelty scores, which reflect the relative amount of time infants look at new compared to familiar stimuli, constituted the measure of infant visual processing. These scores, obtained by averaging over performance on the 3 or 4 problems administered at 6 months of age, were consistently and significantly related to cognitive measures from 24 months to 6 years, with correlations ranging from r = .53 to r = .66. Parental education, which was unrelated to novelty scores, bore a strong relationship to outcome beginning at 24 months. Although both measures contributed uniquely to the variance in cognitive outcome at 24 months and 6 years, visual novelty scores made a stronger contribution than did parental education. Neither 6- nor 12-month Bayley scores, nor various perinatal variables, were related to outcome.  相似文献

This study examined language-specific links among auditory processing, linguistic prosody awareness, and Mandarin (L1) and English (L2) word reading in 61 Mandarin-speaking, English-learning children. Three auditory discrimination abilities were measured: pitch contour, pitch interval, and rise time (rate of intensity change at tone onset). Linguistic prosody awareness was measured three ways: Mandarin tone perception, English stress perception, and English stress production. A Chinese character recognition task was the Mandarin L1 reading metric. English L2 word reading was assessed by English real word reading and nonword decoding tasks. The importance of the auditory processing measures to reading was different in the two languages. Pitch contour discrimination predicted Mandarin L1 word reading and rise time discrimination predicted English L2 word reading, after controlling for age and nonverbal IQ. For the prosodic and phonological measures, Mandarin tone perception, but not rhyme awareness, predicted Chinese character recognition after controlling for age and nonverbal IQ. In contrast, English rhyme awareness predicted more unique variance in English real word reading and nonword decoding than did English stress perception and production. Linguistic prosody awareness appears to play a more important role in L1 word reading than phonological awareness; while the reverse seems true for English L2 word reading in Mandarin-speaking children. Taken together, auditory processing, language-specific linguistic prosody awareness, and phonological awareness play different roles in L1/L2 reading, reflecting different prosodic and segmental structures between Mandarin and English.  相似文献

Indirect effects of preschool classroom indexes of teacher talk were tested on fourth-grade outcomes for 57 students from low-income families in a longitudinal study of classroom and home influences on reading. Detailed observations and audiotaped teacher and child language data were coded to measure content and quantity of verbal interactions in preschool classrooms. Preschool teachers' use of sophisticated vocabulary during free play predicted fourth-grade reading comprehension and word recognition (mean age=9; 7), with effects mediated by kindergarten child language measures (mean age=5; 6). In large group preschool settings, teachers' attention-getting utterances were directly related to later comprehension. Preschool teachers' correcting utterances and analytic talk about books, and early support in the home for literacy predicted fourth-grade vocabulary, as mediated by kindergarten receptive vocabulary.  相似文献

Measures of early family adversity, pre-school-age IQ, school-age IQ, and reading ability were obtained from 779 Dunedin children. The data were used to examine the role of reading ability in the relationship between intellectual performance and teacher-reported behavior problems. Results of regression analyses showed that family adversity and pre-school-age IQ predicted problem behavior during the first year at school. However, reading scores accounted for a larger proportion of the variance in the later behavior problem scores than did school-age IQ scores, and when reading ability was entered in the regression equation before IQ, then reading but not IQ significantly predicted change in problem behavior during the primary school years. The results indicated that the association between IQ scores and problem behavior was mediated by reading ability and that a measure of school-age IQ has limited usefulness for models of primary school-age problem behavior.  相似文献
