Abstract

The purpose of this study was to determine the impact the presence conventional written numerals has on solving additives problems. We asked 45 children (aged four and five) to solve ten different 5 + 3 type problems by adding tokens that were placed into an opaque box in view of the children. The participants’ performance in counting, recognizing written numerals and solving a number conservation task were assessed. The results suggest that the presence of written numerals facilitated children’s ability to perform additive operations: they were able to use these numerals as a reference to calculate the amount of tokens added, even those who had not shown good quantitative judgement in the number conservation task. Identifying preschoolers’ possible reliance on written numerals could eventually influence formal teaching conditions.  相似文献

Although clinical practitioners often express concerns about the mathematical functioning of children with autism spectrum disorder (ASD), the field of mathematics remains a relatively unexplored topic in individuals with ASD. Moreover, research findings are fragmentary and hold inconclusive results. The present study aimed to examine whether grade 1 (aged 6–7 years) to 4 (aged 9–10 years) elementary school children with ASD scored significantly different from age‐adequate norms on mathematics. To this end, a multi‐componential approach of mathematics was used. Four domains of mathematics were assessed in 121 children with ASD: procedural calculation, number fact retrieval, word/language problems, and time‐related competences. All children attended general education classrooms, following the standard curriculum, and were coached by integrated educational services. Children with ASD showed a strength in word/language problems in second and fourth grade. There was evidence of a weakness for procedural calculation in first grade and for time‐related competences in first and third grade. In all other cases, average scores were shown. As such, results revealed a profile of strengths, average abilities, and weaknesses in mathematics and highlighted the importance of focusing on different domains of mathematics. Because a high variability in mathematical performance could be observed, we recommend an individual assessment when considering the mathematical trajectory of children with ASD.

Unsociable children are likely to develop adjustment difficulties in Chinese society. The primary goal of the present study was to examine the moderating effect of behavioural control on the relation between unsociability and peer problems in Chinese children. Participants were fourth to eighth grade students in urban China (N = 787). Assessments of unsociability, shyness, peer problems and behavioural control were obtained from peer nominations and teacher ratings. Results indicated that unsociability was positively related to peer problems in Chinese children after controlling for shyness. Also, the relation between unsociability and peer problems was attenuated among children with higher behavioural control. Thus, behavioural control may be a buffering factor that serves to protect unsociable children from developing peer problems. Gender and age also moderated these associations. Results are discussed in terms of the meaning and implications of unsociability and behavioural control in Chinese culture. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

We examined among college students the interactive effects of drinking to cope (DTC) motivation, anxiety and depression symptoms, and drinking level in predicting drinking-related problems (DRPs). Using an Internet-based survey, participants (N = 844, 53% women) first reported on their drinking motives and monthly for up to three months, they reported on their drinking level, anxiety, depression, and DRPs. We found a three-way interaction between DTC motivation and average levels of drinking and anxiety (but not depression) in predicting DRPs. Specifically, among individuals with stronger DTC motives, higher mean levels of anxiety were associated with a stronger positive association between mean drinking levels and DRPs. We did not find three-way interactions in the models examining monthly changes in anxiety, depression, and drinking in predicting monthly DRPs. However, individuals high in DTC motivation showed a stronger positive association between changes in drinking level and DRPs. The results are discussed in terms of mechanisms related to attention-allocation and self-control resource depletion.  相似文献

Prolonged stress (≥ six months) may cause a condition which has been named exhaustion disorder (ED) with ICD‐10 code F43.8. ED is characterised by exhaustion, cognitive problems, poor sleep and reduced tolerance to further stress. ED can cause long term disability and depressive symptoms may develop. The aim was to construct and evaluate a self‐rating scale, the Karolinska Exhaustion Disorder Scale (KEDS), for the assessment of ED symptoms. A second aim was to examine the relationship between self‐rated symptoms of ED, depression, and anxiety using KEDS and the Hospital Anxiety and Depression Scale (HAD). Items were selected based on their correspondence to criteria for ED as formulated by the Swedish National Board of Health and Welfare (NBHW), with seven response alternatives in a Likert‐format. Self‐ratings performed by 317 clinically assessed participants were used to analyse the scale's psychometric properties. KEDS consists of nine items with a scale range of 0–54. Receiver operating characteristics analysis demonstrated that a cut‐off score of 19 was accompanied by high sensitivity and specificity (each above 95%) in the discrimination between healthy subjects and patients with ED. Reliability was satisfactory and confirmatory factor analysis revealed that ED, depression and anxiety are best regarded as different phenomena. KEDS may be a useful tool in the assessment of symptoms of Exhaustion Disorder in clinical as well as research settings. There is evidence that the symptom clusters of ED, anxiety and depression, respectively, reflect three different underlying dimensions.  相似文献

Behavior problems are prevalent in young children and those living in poverty are at increased risk for stable, high-intensity behavioral problems. Research has demonstrated that participation in child and parent therapy (CPT) programs significantly reduces problematic child behaviors while increasing positive behaviors. However, CPT programs, particularly those implemented with low-income populations, frequently report high rates of attrition (over 50%). Parental attributional style has shown some promise as a contributing factor to treatment attendance and termination in previous research. The authors examined if parental attributional style could predict treatment success in a CPT program, specifically targeting low-income urban children with behavior problems. A hierarchical logistic regression was used with a sample of 425 families to assess if parent- and child-referent attributions variables predicted treatment success over and above demographic variables and symptom severity. Parent-referent attributions, child-referent attributions, and child symptom severity were found to be significant predictors of treatment success. Results indicated that caregivers who viewed themselves as a contributing factor for their child's behavior problems were significantly more likely to demonstrate treatment success. Alternatively, caregivers who viewed their child as more responsible for their own behavior problems were less likely to demonstrate treatment success. Additionally, more severe behavior problems were also predictive of treatment success. Clinical and research implications of these results are discussed.  相似文献

Deficits in executive function, and in particular, reduced capacity to inhibit a dominant action, are a risk factor for externalizing problems (EP). Inhibitory control (IC) develops in the later preschool and early childhood periods, such that IC might not regulate EP in toddlers and younger preschoolers. Aggression was observed during peer play for 66 girls and 49 boys, from 2.75 to 6.00 years (M=4.14, S.D.=0.78). Mothers reported on children's IC and EP concurrently and 12 months later, and concurrent teacher reports of EP were also collected. Factor analysis supported aggregation of mother and teacher‐reported EP and observed physical aggression into one measure of externalizing difficulties. Mothers reported lower IC for children with more externalizing difficulties, and the inverse relation between IC and externalizing difficulties strengthened over the toddler, preschool and kindergarten periods. Similar relations between IC and EP were observed 12 months later, and increases in IC also predicted reductions in EP over 1 year. These data demonstrate that the preschool years are a dynamic period of developmental change in the relations between IC and EP. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献
