Using the “between-grade levels” regression discontinuity design, this study examined the hypothesized differential sensitivity of logico-mathematical (LM) and infralogical (IL) operational tasks to the effects of chronological age and first grade schooling in a sample of 580 1st and 2nd grade Israeli children. The results indicate that the development of logico-mathematical operational skills (classification, class inclusion and transitivity) is mainly attributable to schooling. In contrast, the effect of schooling on the development of conservation of mass, liquid quantity and number (clearly an infralogical task) is negligible; acquisition of conservation is almost exclusively due to maturation and out-of-school experiences. The results support the theoretical predictions derived from French-Swiss research of the last two decades and are inconsistent with claims regarding the specificity of schooling effects to tasks that are taught in school.  相似文献

Previous research on age and schooling effects is largely restricted to studies of children who begin formal schooling at 6 years of age, and the measures of phoneme awareness used have typically lacked sensitivity for beginning readers. Our study addresses these issues by testing 4 to 6 year-olds (first 2 years of formal schooling in the United Kingdom) on a sensitive dynamic measure of phoneme awareness and tests of early literacy. There were significant effects of both age and schooling on the dynamic measure of phoneme awareness, word reading, spelling, and letter name knowledge, but there were no significant Age × Time interactions. This indicates that older children within this age group generally outperform their younger classmates (although they do not make faster progress) and that this advantage is developed prior to the start of school.  相似文献

A sample of 283 Hispanic children with literacy performance at entrance to first grade below the median for their school district was studied as part of a larger research project on the predictors of grade retention in grade 1. Following retention decisions, 51 Hispanic students were retained in first grade. Low literacy skills, being young at entrance to first grade, low ego resilience, low support in the teacher-student relationship, and parents' low sense of responsibility for their children's educational outcomes predicted retention decisions. Hierarchical logistics regression investigated the contribution of six categories of variables (academic competencies; socio-demographic characteristics; social, emotional, and behavioral adjustment; resiliency, school context; and home environment) to retention. Controlling for literacy, only being young for grade and parents' low sense of responsibility for their children's adjustment to school made a direct contribution to retention. Early literacy skills were higher for children enrolled in bilingual classrooms than for children in non-bilingual classrooms. Implications for educational policy are discussed.  相似文献

Two cognitive tests were administered to typically developing children (36–67 months): the Mullen Scales of Early Learning (MSEL), which is appropriate for very young children and thus often used in research with atypical samples (e.g., children with Autism Spectrum Disorder), and the Kaufman Assessment Battery for Children (K-ABC). This was done in order to re-examine possible MSEL ceiling effects in a new sample and achieve a more in-depth understanding of these ceiling effects, if indeed present. Results indicated that among children ranging in age from 51 to 68 months, MSEL scores were significantly lower than K-ABC scores, and that with increasing age the number of children who completed the MSEL without establishing a ceiling level increased. Our results indicated that the MSEL scores are affected by ceiling effects and, therefore, the test underestimates cognitive abilities among older and more cognitively able children.  相似文献

To investigate the time course of predictability effects in reading, the present study examined distributions of first-fixation durations on target words in a low predictability versus a high predictability prior context. In a replication of Staub (2011), ex-Gaussian fitting demonstrated that the low predictability distribution was significantly shifted to the right of the high predictability distribution in the absence of any contextual differences in the degree of skew. Extending this finding, the present study used a survival analysis technique to demonstrate a significant influence of predictability on fixation duration as early as 140 ms from the start of fixation, which is similar to prior results obtained with the word frequency variable. These results provide convergent evidence that lexical variables have a fast acting influence on fixation durations during reading. Implications for models of eye-movement control are discussed.  相似文献

Analysing the relationship between gender and memory, and examining the effects of age on the overall memory-related functioning, are the ongoing goals of psychological research. The present study examined gender and age group differences in episodic memory with respect to the type of task. In addition, these subgroup differences were also analysed in visual working memory. A sample of 366 women and 330 men, aged between 16 and 69 years of age, participated in the current study. Results indicate that women outperformed men on auditory memory tasks, whereas male adolescents and older male adults showed higher level performances on visual episodic and visual working memory measures. However, the size of gender-linked effects varied somewhat across age groups. Furthermore, results partly support a declining performance on episodic memory and visual working memory measures with increasing age. Although age-related losses in episodic memory could not be explained by a decreasing verbal and visuospatial ability with age, women's advantage in auditory episodic memory could be explained by their advantage in verbal ability. Men's higher level visual episodic memory performance was found to result from their advantage in visuospatial ability. Finally, possible methodological, biological, and cognitive explanations for the current findings are discussed.  相似文献

This study examined the role of suppressor effects on age differences in anxious emotion. Children and adolescents (n = 1099) ages 7–18 years were assessed for separation anxiety, social anxiety, and generalized anxiety. Results of zero-order correlations indicated a significant negative association between age and separation anxiety but no association for social anxiety and generalized anxiety. However, semi-partial correlations indicated the presence of a cooperative suppressor effect such that the associations between age and social anxiety as well as age and generalized anxiety symptoms became significant and positive and the association with separation anxiety became larger in a simultaneous regression analysis of each facet with age. Similar effects occurred when controlling for hyperarousal in an ANCOVA across grade levels. Results suggest that attempts to understand developmental differences in anxious emotion in childhood and adolescence will be facilitated by parsing facets of anxious emotion and attention to potential suppressor effects.  相似文献

Studies of visually goal-directed arm movements in adults have shown that various task constraints such as intention, context, and object properties affect different kinematic characteristics of the movement components (Jeannerod, 1984; MacKenzie et al., 1987; Marteniuk et al., 1987, 1990; Paulignan et al., 1991; Soechting, 1984). The purpose of the present study was to compare the effects of varying object size on the kinematics of reaching and grasping in both children and adults. Five children aged 9–10 years and five adults aged 18–24 years reached for and grasped three different sized cubes. Results revealed that object size had the same effect on the planning and control of reaching and grasping movements in children as in adults. Unlike adults, however, children in this age range spent more time in deceleration and reached peak aperture much later in the movement trajectory. The results were interpreted as immature integration of the visual and proprioceptive systems in 9–10 year olds. The implications of these findings for further examining developmental trends in prehension are discussed.PsycINFO classification: 2330  相似文献

ABSTRACT

We examined 5-year longitudinal changes in Tower of Hanoi (TOH) performance in a population-based sample of adults (35–85 years initially; n?=?1480). An age-matched sample (n?=?433) was included to estimate practice effects. The longitudinal age gradients differed substantially from the cross-sectional age gradients. This was the case even when practice effects, that were substantial in magnitude across the young/middle-aged groups, were controlled for. Instead of a continuous age-related deficit in performance from 35 and onwards, longitudinal data showed slowing of performance and increases of illegal moves past age 65. Cohort-related differences in educational attainment did not account for this discrepancy. Further analyses revealed a positive relation between practice-related gains and explicit memory of having performed the task at the first test occasion and a positive association between latent changes in TOH and Block Design, in line with cross-sectional findings. In conclusion, the results demonstrate a pattern of age-related changes indicating a late-onset decline of TOH performance and underscore the need to control for retest effects in longitudinal aging research.  相似文献

We examined the development of stress assignment in reading Italian aloud. We investigated frequency effects as a marker of the use of item-specific lexical knowledge in assigning stress together with stress dominance and stress neighbourhood (the number of words sharing both stress and ending) as markers of distributional information regarding properties of the lexicon extracted from spoken language. We tested second- and fourth-graders in a reading-aloud experiment including high- and low-frequency words and nonwords. Results show that despite the regularity of orthography–phonology mappings in Italian and the predominant use of phonological recoding procedures, item-specific lexical knowledge is also used, even by beginning readers. The frequency effect was significant and did not increase with age, while stress errors on low-frequency words decreased with increasing grade. Stress neighbourhood increasingly affected stress assignment on nonwords with older children. Taken together, our findings show that both item-specific knowledge and general information about stress distribution are relevant in children's reading, suggesting the simultaneous use of both lexical and sublexical information. Moreover, as the reading system develops, and knowledge about the relative distribution of stress neighbourhood increases, larger grain-size units are also exploited.  相似文献

IntroductionStudies conducted in recent decades have led to the development of instructional interventions to help prevent or eliminate a large proportion of reading difficulties. However, few experiments have been conducted in French schools.ObjectiveAims for this research were to create, implement and evaluate a remediation program for French students with reading difficulties up to the end of elementary school.MethodThis paper examines the effects of a decoding-skills and fluency-based intervention on 133 struggling readers in second- to fifth-grade. Depending on the nature of their reading difficulties, students were given a year-long training based either on grapho-syllabic conversion — focusing on syllable units, rather than phonemic units, is considered a promising way of helping French-speaking beginning readers — or on repeated reading techniques, used to improve fluency.ResultsIncreases in written-word identification scores were greater for students who followed the program than they were for a control group of 184 students with reading difficulties who did not follow the program.ConclusionThe results show that programs combining early evaluation of written-word identification abilities followed by a year-long series of remediation sessions focusing on specific difficulties can help students progress in written-word identification. However, further research is needed to examine why our program was less effective with children from disadvantaged (“éducation prioritaire”) areas.  相似文献

Numerous studies have focused on the distinction between categorical and coordinate spatial relations. Categorical relations are propositional and abstract, and often related to a left hemisphere advantage. Coordinate relations specify the metric information of the relative locations of objects, and can be linked to right hemisphere processing. Yet, not all studies have reported such a clear double dissociation; in particular the categorical left hemisphere advantage is not always reported. In the current study we investigated whether verbal and spatial strategies, verbal and spatial cognitive abilities, and gender could account for the discrepancies observed in hemispheric lateralization of spatial relations. Seventy-five participants performed two visual half field, match-to-sample tasks (Van der Ham, van Wezel, Oleksiak, & Postma, 2007; Van der Ham, Raemaekers, van Wezel, Oleksiak, and Postma, 2009) to study the lateralization of categorical and coordinate relation processing. For each participant we determined the strategy they used in each of the two tasks. Consistent with previous findings, we found an overall categorical left hemisphere advantage and coordinate right hemisphere advantage. The lateralization pattern was affected selectively by the degree to which participants used a spatial strategy and by none of the other variables (i.e., verbal strategy, cognitive abilities, and gender). Critically, the categorical left hemisphere advantage was observed only for participants that relied strongly on a spatial strategy. This result is another piece of evidence that categorical spatial relation processing relies on spatial and not verbal processes.  相似文献

This study examined the role of early visual experience and age in the recognition of emotional prosody among students with visual impairments in China. A total of 75 primary and junior high school students participated in the study. The ability of participants to recognize the prosody of four basic emotions (sadness, anger, happiness, and neutrality) was explored. The findings were as follows. (1) Early visual experience had a significant effect on the recognition of emotional prosody. The accuracy rate of students with congenital blindness was lower than that of students with adventitious blindness, and the performance of students with congenital blindness was lower than that of sighted students. The students with congenital blindness exhibited the slowest recognition speeds. (2) Age had a significant effect on the emotional prosody recognition accuracy of the sighted students, but it had no effect on the students with blindness.  相似文献

A domain-specific hierarchical conceptualization of mathematics achievement can be represented by the standard psychometric model in which a single latent dimension accounts for observed individual differences in scores on the respective subdomains (e.g., quantity). Alternatively, a fully hierarchical conceptualization of achievement can be represented by a nested-factor model in which individual differences in subdomain-specific scores are explained by both general student achievement and specific mathematics achievement. The authors applied both models to study the gender similarity hypothesis, the greater male variability hypothesis, and the masking hypothesis, which predicts that gender differences in general student achievement mask gender differences in both the means and the variability of specific mathematics achievement. Representative data were obtained from 275,369 15-year-old students in 41 countries. The results supported these hypotheses in most countries, demonstrating that a fully hierarchical conceptualization of achievement in terms of the nested-factor model significantly contributes to a better understanding of gender differences in the mean level, variability, and shape of students' achievement profiles.  相似文献

We present a novel lexical decision task and three boundary paradigm eye-tracking experiments that clarify the picture of parallel processing in word recognition in context. First, we show that lexical decision is facilitated by associated letter information to the left and right of the word, with no apparent hemispheric specificity. Second, we show that parafoveal preview of a repeat of word n at word n + 1 facilitates reading of word n relative to a control condition with an unrelated word at word n + 1. Third, using a version of the boundary paradigm that allowed for a regressive eye movement, we show no parafoveal “postview” effect on reading word n of repeating word n at word n – 1. Fourth, we repeat the second experiment but compare the effects of parafoveal previews consisting of a repeated word n with a transposed central bigram (e.g., caot for coat) and a substituted central bigram (e.g., ceit for coat), showing the latter to have a deleterious effect on processing word n, thereby demonstrating that the parafoveal preview effect is at least orthographic and not purely visual.  相似文献

The stability in the new morbidity-problem domains motor skills, reading/writing ability, behavioral–psychological–social function and concentration ability in school, and the stability of peer status and peer preferences as well as relationships between peer status and problems among boys and girls was studied in a sample of 81 Swedish primary school children. The children were rated by teachers and made peer nominations six months after school start, and in the third grade.
There was considerable stability in problems, while the stability in peer status was modest. There were marked gender differences. Boys in contrast to girls improved in motor skills from the first to the third grade, and boys had more concentration problems and multiple problems than girls in both grade 1 and 3. In the first grade, low peer acceptance in boys was accompanied by low motor skill. In the third grade, low peer acceptance in boys was accompanied by deficient concentration ability and externalizing problems. For girls, few relationships between low peer acceptance and problems emerged. Various explanations for these findings are discussed.  相似文献

While diathesis-stress models of cognitive vulnerability to depression (CVD) in childhood have been tested, few studies have included both parent- and child-reported negative life events, despite the fact that they provide unique information on events that may be relevant to depression risk in boys and girls. It was hypothesized that different types of stress may show moderation of CVD for boys and girls; specifically, we predicted that parent-reported stressors may moderate boys’ CVD, and that self-reported stress may play a more critical moderating role for girls. A community sample of 182 eight-year-olds completed measures of CVD at baseline, and child- and parent-reported measures of stress were collected at follow-up, one year later. Support for diathesis-stress models of CVD varied depending on child sex and the source of information on stress. Results highlight the importance of collecting multiple measures of stress in testing diathesis-stress models of CVD in middle childhood.  相似文献

The main aim of the current study was to test the cognitive content‐specificity hypothesis across internalizing and externalizing problems in Chinese adolescents. The participants consisted of 2,158 adolescents aged 11–19 years from three middle schools, and they completed a number of measures assessing a wide range of automatic thoughts and syndromes related to internalizing and externalizing problems. Multivariate regression analyses demonstrated that thoughts about social threats, personal failure and hostility were the strongest predictors of anxiety, depression, and externalizing problems, respectively. Age was a statistically significant, albeit modest, moderator of the relationship between automatic thoughts about social threat and anxiety. The current study provides support for the cognitive content‐specificity hypothesis in internalizing and externalizing problems in a Chinese sample.  相似文献

The aim of this paper was to study gender differences in the percept-genetic method Defense Mechanism Test (DMT) among a group of 60 adolescent subjects. Three subgroups were used: patients with psychotic disorders (Axis 1); borderline personality disorder (Axis 2) according to the DSM-IV classification system, and a non-patient group. The test protocols were scored with respect to 124 DMT variables and analyzed by means of the multivariate projection method Partial Least Squares (PLS) in latent structures. The overall results showed considerable gender differences in the whole group as well as in the subgroups. The most striking finding was that girls compared to boys were characterized by the perceptual defense identification with the opposite sex, which means that they perceived male gestalts instead of females in the stimulus picture. When both gender and diagnostic group membership were considered simultaneously, the influence of diagnostic group membership seemed to be stronger than gender even if there was an interaction between diagnoses and gender. It was concluded that gender must be considered when the DMT is used on adolescent populations.  相似文献

For over four decades the Wisconsin Card Sorting Test (WCST) has been one of the most distinctive tests of prefrontal function. Clinical research and recent brain imaging have brought into question the validity and specificity of this test as a marker of frontal dysfunction. Clinical studies with neurological patients have confirmed that, in its traditional form, the WCST fails to discriminate between frontal and non-frontal lesions. In addition, functional brain imaging studies show rapid and widespread activation across frontal and non-frontal brain regions during WCST performance. These studies suggest that the concept of an anatomically pure test of prefrontal function is not only empirically unattainable, but also theoretically inaccurate. The aim of the present review is to examine the causes of these criticisms and to resolve them by incorporating new methodological and conceptual advances in order to improve the construct validity of WCST scores and their relationship to prefrontal executive functions. We conclude that these objectives can be achieved by drawing on theory-guided experimental design, and on precise spatial and temporal sampling of brain activity, and then exemplify this using an integrative model of prefrontal function [i.e., Miller, E. K. (2000). The prefrontal cortex and cognitive control. Nature Reviews Neuroscience, 1, 59–65.] combined with the formal information theoretical approach to cognitive control [Koechlin, E., & Summerfield, C. (2007). An information theoretical approach to prefrontal executive function. Trends in Cognitive Sciences, 11, 229–235.].  相似文献
