Past research on social marking and pragmatic reasoning schemas suggest that cognitive processing modes are first elaborated by children when are carying out regulating social routines in the course of which they learn to produce the responses that satisfy the demand of their environment. The data of five experimental studies with 3–6 year old children, for object distribution tasks, are reported here. The data of the three first experiments show that the social routines evoked by the objects to be processed have a dual effect, influencing both the representation of the partition to be made, as well as the procedures used to make them. The data of the two last experiments seems to attest that, in training situations, the utilization of routine-evoking tasks promotes the construction of more general schemas, by the attribution of an operative meaning to the linguistic expressions used to characterize the states to be attained, and the transformations to be applied in order to attain them.  相似文献

Several recent studies have shown that retrieval is more efficient than restudy in enhancing the long-term retention of memories. However, studies investigating this effect in children are still rare. Here, we report an experiment in which third-grade children initially read a brief encyclopaedic text twice and then either performed a cued recall test on selected target contents of the text or reread the same text twice. A final four-choice memory test about the text’s contents was administered to all children after seven days as well as tests measuring their IQ and reading skills. In the final four-choice memory test, children who took the initial cued recall test showed significantly greater performance in comparison with children who restudied the text twice (their responses were 87 and 53% correct, respectively). The results suggest that cued recall tests can elicit very robust testing effects in young children, even when complex, educationally relevant materials are used as stimuli.  相似文献

In order to read fluently, children have to form orthographic representations. Despite numerous investigations, there is no clear answer to the question of the number of times they need to read a word to form an orthographic representation. We used length effect on reading times as a measure, because there are large differences between long and short words for unknown words, differences that disappear when reading frequent words. Two lists of new words (half short and half long) were presented to 102 second‐grade to sixth‐grade Spanish children, to be read aloud six times. One of the lists was presented as part of a story and the other in isolation. Comparison of the length effect at the first and sixth exposure showed large differences between short and long words in the first presentation and small differences at the sixth presentation, indicating that Spanish children develop representations of words after just a few repetitions.  相似文献

This study explored the arithmetic skills of 39 children with arithmetic learning difficulties (ALD), compared to two control groups, one consisting of normally achieving children matched to the ALD sample for chronological age (n=28), and another comprising younger normally achieving children matched to the ALD sample for arithmetic level (n=28). To determine the relative contribution of reading impairments to arithmetic performance, the ALD group was further classified according to the presence or absence of reading difficulties into a mixed ALD (n=24) and specific ALD (n=15) group, respectively. The ALD group performed well below their chronological age counterparts in terms of the developmental maturity of their arithmetic problem solving. These children demonstrated a reliance on slow, counting-based procedures to solve arithmetic problems and, in this regard, they performed similarly to their younger, arithmetic-matched normal peers. Children with ALD also employed direct fact retrieval reliably less often than their same-age peers, but did not differ from their younger, arithmetic-matched counterparts. There were few significant differences between ALD children with and without accompanying reading problems. The findings suggest that children with ALD appear to show delayed development of arithmetic skills rather than specific processing deficits or abnormalities when comparison is made with both their chronological age and arithmetic-matched normal peers.  相似文献

A longitudinal study was conducted on 82 children to investigate, firstly the numerical competence of young children and the predictive value of (pre)-numerical tests in kindergarten, and, secondly, whether children's knowledge of the numerical system and representation of the number size is related to their computation and logical knowledge and to their counting skills. In an additional cross-sectional study on 30 children with a clinical diagnosis of mathematical learning disability (MLD) of 8,5 years, age- and ability-matched with 2 × 30 children the same parameters of numerical competence were assessed. The longitudinal data showed individual differences in numerosity, as well as the relationship between a delay in arithmetics in grade l and problems on numerosity in kindergarten. In the cross-sectional results some evidence was found for the independence of numerical abilities in MLD-children. About 13% of them had still severe pre-numerical processing deficits (in number sequence production, cardinality skills and logical knowledge) in grade 3. About 67% had severe difficulties in executing calculation procedures and a lack of conceptual knowledge. A feature of 87% of the MLD-children was severe translation deficits, with a significantly worse knowledge of number words compared with the knowledge of Arab numerals. Finally a severe deficit in subitizing was found to be present in 33% of the MLD children. On a group level the processing deficits were linked to understanding numerosity, since the ability-matched younger children and the MLD-children had the same pre-numerical and numerical profile. Implications for the assessment of mathematical disabilities and the value of TEDI-MATH® as an instrument in this process are discussed.  相似文献

This study evaluated the effect of sound-symbol association training on visual and phonological memory in children with a history of dyslexia. Pretests of phonological and visual memory, a sound-symbol training procedure, and phonological and visual memory posttests were administered to children with dyslexia, to children whose dyslexia had been compensated through remedial training, and to age- and reading level-matched comparison groups. Deficits in visual and phonological memory and memory for sound-symbol associations were demonstrated in the dyslexia group. For children with dyslexia and children whose dyslexia had been remediated, the sound-symbol training scores were significantly associated with word and pseudoword reading scores and were significantly lower than those of the comparison groups. Children with dyslexia and children whose dyslexia had been compensated showed significantly less facilitation of phonological memory following the training than did typical readers. Skilled readers showed some reduction in accuracy of visual memory following the training, which may be the result of interference of verbalization with a predominantly visual task. A parallel decrease was not observed in the children with dyslexia, possibly because these children did not use the verbal cues. Children with dyslexia and children whose dyslexia had been compensated seemed to have difficulty encoding the novel sounds in memory. As a result, they derived less phonological memory advantage and less visual memory interference from the training than did typical readers. Children in the compensated dyslexia group scored lower on sound-symbol training than their age peers. In other respects, the scores of these children were equivalent to those of the typically reading comparison groups. Children in the compensated dyslexia group exhibited higher phonological rehearsal, iconic memory, and associative memory scores than children in the dyslexia group. Implications for the remediation of dyslexia are discussed.  相似文献

Incidental learning of film content was investigated in institutionalized retarded children. In the first of two studies, 40 retardates at six IQ levels, three MA levels, and five CA levels were tested. In the second study, 21 Down's Syndrome, organic, and familial retardates were tested. The stimuli consisted of an 8‐minute film which was shown individually. All subjects were questioned on twenty incidental aspects of the film. In Experiment 1, a curvilinear relationship was found between incidental learning and IQ. Incidental learning improved with MA. A retest, taken 120 hours later, revealed a 10.9 percent loss of incidental learning. Higher IQ children showed the greatest loss. Experiment 2 reported no difference in incidental learning as a function of etiology of retardation. A retest showed a short term memory deficit in organic retardates and a significant loss of incidental learning in Down's Syndrome and familial retardates. Implications of these results were discussed in terms of structured teaching techniques.  相似文献

Reading fluency is one of the basic processes of learning to read. Children begin to develop fluency when they are able to form orthographic representations of words, which provide direct, smooth, and fast reading. Dyslexic children of transparent orthographic systems are mainly characterized by poor reading fluency (Cuetos & Suárez-Coalla 2009; Spinelli, De Luca, Di Filippo, Mancini, Martelli, & Zoccolotti, 2005; Wimmer, 1993). Therefore, the main problem for these children could be the difficulty in developing orthographic representations of the words they read. The aim of this study was to test the ability of dyslexic Spanish-speaking children (whose native language is Spanish) to develop orthographic representations and determine if the context helps them. For this, two experiments were conducted with a group of 100 children, 7–12 years of age. The groups were comprised of 20 dyslexics, 40 chronological age-matched controls and 40 reading level-matched controls. In the first experiment, eight unfamiliar words (four short and four long) were presented six times within the context of a story. In the second experiment, eight pseudowords were presented on a computer and the children had to read them aloud. In both experiments, the reading and articulation times of experimental and control stimuli were compared, before and after the training. Children without dyslexia showed a decrease of the influence of length of word on reading speed, indicating a lexical reading, while for dyslexic children, the influence of length remained unchanged. These results appeared when the stimuli were presented in the context of a story as well as when presented in isolation. In short, our results describe that dyslexic children of transparent orthographic systems have problems in developing orthographic representations of words.  相似文献

The study examined the performance of 30 learning disabled and 30 nondisabled children in grades 1 through 7 on the Test of Social Inference (TSI). Results indicated that disabled students obtained lower TSI total scores that did nondisabled students: they also performed relatively lower on TSI items requiring more verbal expression. While no difference was found between the groups on the Motor-Free Visual Perception Test (MVPT), the relationship between MVPT and TSI scores was shown to be significant within the disabled group only. Furthermore, this group made more perceptual-type errors on the TSI. Findings are discussed in relation to previous research suggesting a link between visual perception and/or language fluency and social inference skills among learning disabled children.  相似文献

Sustained and selective attention in children with learning disabilities   总被引:2,自引:0,他引:2  
Sustained and selective attention of 30 fourth-, fifth-, and sixth-grade students with learning disabilities (LD) and 20 controls were compared. A continuous performance test (CPT) yielded no differences for students with LD and controls, suggesting similar ability for both groups in sustaining attention and inhibiting impulsive responding. Subjects with LD made more errors than controls on a selective attention task when letter distractors were adjacent to the target letter but not when they were distant, and more correct responses than controls when facilitating letters were adjacent to the target, suggesting that students with LD are less able to narrow the focus of their attention. Longer response times by students with LD indicate that they have slower information-processing skills than controls. Regrouping students according to teacher ratings for attention deficit-hyperactivity disorder (ADHD) yielded the customary impulsive response set on the CPT and more errors on the selective attention task, but no differences on response times for students with ADHD. LD students with ADHD made more errors than LD students without ADHD when letter distractors were adjacent to the target letter.  相似文献

The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States learned novel categories with features that were easy (e.g., “red”) or difficult (e.g., “mauve”) to name. Adults (d = 1.06) and—to a lesser extent—children (d = 0.57; final training block) learned categories composed of more nameable features better. Children's knowledge of difficult-to-name color words predicted their learning for categories with difficult-to-name features. Rule-based category learning may be supported by the emerging ability to form verbal hypotheses.  相似文献
