Using data from the Fragile Families and Child Wellbeing Study (N = 3,870) and cross‐lagged path analysis, the authors examined whether spanking at ages 1 and 3 is adversely associated with cognitive skills and behavior problems at ages 3 and 5. The authors found spanking at age 1 was associated with a higher level of spanking and externalizing behavior at age 3, and spanking at age 3 was associated with a higher level of internalizing and externalizing behavior at age 5. The associations between spanking at age 1 and behavioral problems at age 5 operated predominantly through ongoing spanking at age 3. The authors did not find an association between spanking at age 1 and cognitive skills at age 3 or 5.  相似文献

This article compares a child’s drawings at home with a child’s drawings at school. The drawings were of maps, which had been a school topic. As part of a longitudinal study looking at children’s text making at home and at school three particular homes were focused on for eighteen months. This article looks at one home – that of a six year old Turkish boy who lives with his mother and brother. The case study illustrates how children can take something learned at school and transform it at home. The article starts with discussing the text created in the home, then compares this to texts created at school. The point is made that children can activate meaning in a different way at home than at school. While this is one case study, it suggests that transforming artefacts across sites may be something children do that often goes undocumented.  相似文献

To evaluate the accuracy of SEARCH as a screen for identifying children at risk for developing learning problems, 1107 kindergarten children were evaluated with SEARCH and 284 (26 percent) were classified as at risk. At-risk children were of average intelligence and SEARCH scores were significantly correlated with sequential and simultaneous information processing skills. Children whose group preacademic achievement scores were at or below the third stanine at the end of kindergarten were classified as having inadequate skills for learning how to read; those scoring above the third stanine formed the adequate skills group. Using this criterion, SEARCH predicted children who had adequate or inadequate preacademic reading skills with 77 percent accuracy. However, approximately half of the children identified as at risk by SEARCH performed adequately. A reading test was individually administered to a group of at-risk children at the end of first (N=49) and second (N=35) grade. Of those children identified at risk by SEARCH at kindergarten, 39 percent at first grade and 66 percent at second grade performed at grade level. Fewer children from the upper SES were identified by SEARCH as being at risk.  相似文献

大鹏湾属不规则半日混合潮港,潮流亦属不规则半日混合潮型。潮流受制于南海潮流系统,涨潮时东半部先出现涨潮流,流速约为10cm/s,西半部滞后3小时左右,流速略大于东部;落潮时先从东半部向东南方向流出,平均流速为10cm/s,落潮流东部流出时,西部仍向湾内流入,最大流速达62cm/s.因此,涨潮时北半部形成一个半封闭式的逆时针向环流,落潮时则形成半封闭式的顺时针向环流。余流流速较小,一般为7cm/s以下,通常北部大于南部,西部大于东部,在海湾内也形成一个逆时针向环流。  相似文献

Children who think poorly about themselves are considered at-risk for a myriad of negative outcomes. Thus, it is important to explore possible origins of such cognitions, particularly in young children. The purpose of this study was to examine the relations between various nonsocial behaviors (i.e., reticence and social withdrawal), observed peer acceptance at ages 4 and 7 years, and self-perceptions at age 7 years in both boys and girls, respectively.Participants included 163 children (89 females, 74 males) who were seen at age 4 and then again at age 7 years. For girls, results revealed that nonsocial behavior (both reticence and solitary-passive withdrawal) was negatively related to observed peer acceptance at both ages 4 and 7, and peer acceptance, as early as 4 years of age, was found to influence self-perceptions of competence at age 7 years. For boys, results revealed that (a) reticence at age 7 predicted negatively to perceived peer acceptance, perceived physical and perceived cognitive competence at age 7 years, (b) solitary-passive withdrawal at age 4 predicted positive cognitive self-perceptions at age 7, and (c) solitary-passive withdrawal at age 7 predicted negatively to perceived peer acceptance and perceived physical competence at age 7 years.  相似文献

The purpose of this study was to examine the relations among infant temperament, attachment, and behavioral inhibition. 52 infants were seen at 2 days, 5, 14, and 24 months of age. Assessments were made of temperament at 2 days and 5 months of age, and attachment and behavioral inhibition were assessed at 14 and 24 months, respectively. EKG was recorded at each assessment, and measures of heart period and vagal tone were computed. Distress to pacifier withdrawal at 2 days of age was related to insecure attachment at 14 months. 2 types of distress reactivity at 5 months, reactivity to frustration and reactivity to novelty, were identified and related to high vagal tone. Attachment classification at 14 months was directly related to inhibited behavior at 24 months. Infants classified as insecure/resistant were more inhibited than those classified as insecure/avoidant. In addition, an interaction of infant reactivity to frustration and attachment classification was found to predict inhibition at 24 months. Infants classified as insecure/resistant and who had not cried to the arm restraint procedure at 5 months were the most inhibited at 24 months. These findings are discussed in terms of hypotheses regarding multiple modes of distress reactivity and regulation in early infancy and their different social and behavioral outcomes.  相似文献

OBJECTIVE: To examine factors associated with bullying and victimization from age 8 to 16. METHOD: An 8-year longitudinal study included questions about bullying and victimization at age 8 and 16. Children were evaluated with Rutter scales by parents and teachers and with the Child Depression Inventory filled in by the children at age 8. When the children were at the age of 16 parents filled in the CBCL and adolescents the YSR. RESULTS: About 15% of boys and 7% of girls were bullied and 12% of girls and 13% of boys were victimized at age 16. Both bullying and victimization at age 16 were associated with a wide range of psychological problems at age 8 and 16, and with referral to child mental health services. Bullying at age 8 was associated with bullying at age 16, while victimization at age 8 was associated with victimization 8 years later. CONCLUSIONS: Bullying and victimization are often persistent and associated with severe emotional and behavior problems. Preventive efforts should be focused, and targeted at those children who are characterized by both psychological disturbance and bullying.  相似文献

The MacArthur-Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N = 113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and receptive language and measures from parent-child conversation. Associations indicated reasonable concurrent and predictive validity. The findings suggest that satisfactory vocabulary scores at age 2 are likely to predict normal language skills at age 3, although some children with limited skills at age 3 will have had satisfactory scores at age 2. Many children with poor vocabulary scores at 2 will have normal skills at 3.  相似文献

Mothers' mental‐state references predict individual differences in preschoolers' false‐belief (FB) understanding; less is known about the origins of corresponding variation in school‐age children. To address this gap, 105 children completed observations with their mothers at child ages 2 and 6, three FB tasks and a verbal comprehension test at age 3, and five FB tasks at age 6. Seventy‐seven of these children completed five Strange Stories at age 10. Individual differences in mothers' cognitive references at child age 2 predicted variation in children's FB understanding at age 6 and Strange Stories scores at age 10 (controlling for number of mothers' turns and children's mental‐state references, verbal comprehension and FB understanding at age 3, and mothers' cognitive references at child age 6).  相似文献

The crabChasmagnathus granulatus reacts to a shadow passing overhead with an escape response that habituates after 30 trials and for 5 days at least. The effect of a wide range of different intertrial intervals (ITIs) (0, 9, 27, 45, 81, 135, and 171 sec) on theChasmagnathus long-term habituation (LTH) was evaluated at 24 h. Memory retention was estimated separately at two phases of a six-trial testing session: at first trial (the initial testing phase) and at the subsequent block of five trials (the retraining phase). A training of 30 trials with an ITI equal to or longer than 27 sec induced LTH at both testing phases, however, with a 0- or a 9-sec ITI, training wholly failed to build up LTH. When the number of trials was increased, a massed training (ITI=0 or 9 sec) induced LTH at retraining but not at initial testing. Thus, massed training produces LTH only at retraining, whereas spaced training (ITI ≥ 27 sec) produces LTH at both initial phase and retraining. An ITI shift from training to testing diminished or abolished retention at retraining regardless of the direction of the shift, thus suggesting that crabs acquire a memory of the trial-spacing at training. According to these results, it is postulated that LTH consists of two memory components: one produced by spaced training and expressed at both initial testing and retraining, and one yielded by massed training and expressed only at retraining. The possibility that the two components of LTH were differentially affected by cycloxemide and context shift is discussed.  相似文献

The relationships among science and engineering attitude, physics conceptual understanding, and physics achievement were explored for a population of college freshman engineering students over two semesters. Gender and SAT‐Quantitative measures were included as exogenous variables in a longitudinal path analysis. Attitude was theorized to predict achievement contemporaneously and at the next time point, while conceptual understanding was theorized to predict physics achievement contemporaneously and at the next time point. Each at one time was theorized to predict scores at the next time. A sample of 200 freshman engineering students participating in an integrated curriculum were assessed in September, December, and April (with a loss of 64 students) with the Force Concepts Inventory (FCI), Mechanics Baseline Test (MBT), and a locally developed attitude measure. The observed model indicated that the FCI predicted attitude at time 1 with no other paths between them, that FCI at time 1 predicted MBT at time 1 and time 2, FCI at time 2 predicted MBT at time 3, and MBT at time 1 predicted FCI at time 2. Gender and SAT‐Quantitative scores were predictive only of FCI and MBT at time 1. Results supported an interactive model of conceptual understanding and achievement, with attitude largely irrelevant to the process for this population. © 2000 John Wiley & Sons, Inc.
