Number sense development of 411 middle- and low-income kindergartners (mean age 5.8 years) was examined over 4 time points while controlling for gender, age, and reading skill. Although low-income children performed significantly worse than middle-income children at the end of kindergarten on all tasks, both groups progressed at about the same rate. An exception was story problems, on which the low-income group achieved at a slower rate; both income groups made comparable progress when the same problems were presented nonverbally with visual referents. Holding other predictors constant, there were small but reliable gender effects favoring boys on overall number sense performance as well as on nonverbal calculation. Using growth mixture modeling, 3 classes of growth trajectories in number sense emerged.  相似文献

Even when they have good language skills, many children with hearing loss lag several years behind hearing children in the ability to grasp beliefs of others. The researchers sought to determine whether this lag results from difficulty with the verbal demands of tasks or from conceptual delays. The researchers related children's performance on a nonverbal theory of mind task to their scores on verbal aptitude tests. Twelve French children (average age about 10 years) with severe to profound hearing loss and 12 French hearing children (average about 7 years) were evaluated. The children with hearing loss showed persistent difficulty with theory of mind tasks, even a nonverbal task, presenting results similar to those of hearing 6-year-olds. Also, the children with hearing loss showed a correlation between language level (lexical and morphosyntactic) and understanding of false beliefs. No such correlation was found in the hearing children.  相似文献

The purpose of this study was to examine how executive function skills in verbal and nonverbal auditory tasks are related to early reading skills in beginning readers. Kindergarteners (N = 41, aged 5 years) completed verbal (phonemes) and nonverbal (environmental sounds) Continuous Performance tasks yielding measures of executive function (misses, false alarms, and shift) as well as reaction time and D-Prime (sensitivity). Year-end measures of early reading skill included tests of phoneme awareness, letter knowledge, as well as reading (words and nonwords). The children made more errors on the verbal than the nonverbal tasks, suggesting that executive function abilities may differ by task. Adding to the literature on the role of inhibitory skills in reading, verbal inhibitory executive function skills were tied more closely to early reading than other verbal or nonverbal skills when age, short-term memory, and vocabulary were controlled.  相似文献

Our aim in this study was to investigate whether previous findings pointing to a delay in deaf children's theory of mind development are replicated when linguistic demands placed on the deaf child are minimized in a nonverbal version of standard false-belief tasks. Twenty-four prelingually deaf, orally trained children born of hearing parents were tested with both a verbal and a nonverbal version of a false-belief task. Neither the younger (range: 4 years 7 months-6 years 5 months) nor the older (range: 6 years 9 months-11 years 11 months) children of the final sample of 21 children performed above chance in the verbal task. The nonverbal task significantly facilitated performance in children of all ages. Despite this facilitation, we observed a developmental delay: only the older group performed significantly above chance in the nonverbal false-belief task, even though the younger children were at the average age when hearing children normally pass standard false-belief tests. We discuss these findings in light of the hypothesis that language development and conversational competence are crucial to the acquisition of a theory of mind.  相似文献

本研究采用了实验的方法,以言语、非言语性任务,意外转移与表征变化任务为变量,考察了不同语言能力的88名3-4岁幼儿的错误信念理解能力。研究结果发现,降低错误信念任务对语言能力的要求并不能改变幼儿在错误信念理解上的年龄特征;在3岁和4岁两个年龄组中,语言能力超常的幼儿在各项实验任务上的表现均好于语言能力一般的幼儿。  相似文献

A total of 104 six-year-old children belonging to 4 groups (English monolinguals, Chinese-English bilinguals, French-English bilinguals, Spanish-English bilinguals) were compared on 3 verbal tasks and 1 nonverbal executive control task to examine the generality of the bilingual effects on development. Bilingual groups differed in degree of similarity between languages, cultural background, and language of schooling. On the executive control task, all bilingual groups performed similarly and exceeded monolinguals; on the language tasks the best performance was achieved by bilingual children whose language of instruction was the same as the language of testing and whose languages had more overlap. Thus, executive control outcomes for bilingual children are general but performance on verbal tasks is specific to factors in the bilingual experience.  相似文献

This study compared the ease of verbal and nonverbal versions of a number conservation problem for 4and S‐year‐old children. The nonverbal task employed a ‘train‐transfer’ procedure in which children were first trained to a criterial level to make one response to stimulus pairs that contained two rows of the same number in one‐to‐one correspondence and a different response to stimulus pairs in which one of the rows was of greater or of lesser number than the other. Conservation performance was maintaining the learned response to the identical pair after one of its rows had been deformed. Taking both ages together the nonverbal task was the easier. However, children's justifications showed that verbal processes may have been responsible for both correct and incorrect performance in many cases. The data are interpreted as supporting the hypothesis that children interpret conservation terms perceptually when used by others in certain contexts in spite of what they know about the underlying fact of conservation.  相似文献

Metalinguistic and literacy abilities were studied in twenty-seven nonvocal cerebral palsied school children. The participants of the study were presented four tests of phonological awareness: rhyme recognition, sound identification, phoneme synthesis and word length analysis. Their verbal comprehension was measured using a semantic and a syntactic task. Two tests of nonverbal memory: the visual sequential task from ITPA and Corsi blocks and the Digit Span task from WISC, were also included. These measures were related to their reading and spelling ability. The nonvocal children performed on a lower level on the reading and spelling tasks than did the children of two comparison groups, one matched for mental age and one for mental and chronological age. There were no differences in phonological awareness or in verbal memory. The disabled children performed worse on the verbal comprehension task than the children in the comparison groups. Although the reading and spelling results were low in the nonvocal group there were children showing some literacy skills. A within-group analysis performed in the nonvocal group showed that the reading children performed better on all memory tests, and on the sound identification and the word length analysis tasks than the nonreading ones. They also showed better results on verbal comprehension, the semantic task and used more symbols in their communication. Synthetic speech was more often used in reading and spelling education in the reading subgroup than in the nonreading. Metalinguistic abilities and possibility of acoustic rehearsal are discussed as important factors in reading and spelling acquisition in the nonvocal population.  相似文献

This study investigated whether a group of children with reading disabilities (RD) were slower at processing visual information in general (compared to a group of children of comparable age and a group of children of comparable reading level), or whether their deficit was specific to the written word. Computerized backward masking and temporal integration tasks were used to assess the speed of visual information processing. Stimulus complexity (simple, complex) and type (verbal, nonverbal) were varied, creating a 2 x 2 matrix of stimulus conditions: simple nonverbal, complex nonverbal, simple verbal, and complex verbal. Adolescents with RD demonstrated difficulties in processing rapidly presented verbal and nonverbal visual stimuli, although the effect was magnified when they were processing verbal stimuli. Thus, the results of this study suggest that some youth with reading disabilities have visual temporal processing deficits that compound difficulties in processing verbal information during reading.  相似文献

“Game” or “test” instructions on either verbal or nonverbal WISC scales were given to 160 third- and sixth-grade children. Ss in one condition were told they were going to take several tests, while Ss in the other condition were told they were going to play several games. Significant differences in performance due to task definition were found only on verbal tasks at the sixth-grade level with test instructions yielding superior performance. Results at the third-grade level failed to replicate previous results which suggested game instructions produce superior performance on nonverbal tasks.  相似文献

A nonverbal false belief task: the performance of children and great apes   总被引：9，自引：0，他引：9  
A nonverbal task of false belief understanding was given to 4- and 5-year-old children (N = 28) and to two species of great ape: chimpanzees and orangutans (N = 7). The task was embedded in a series of finding games in which an adult (the hider) hid a reward in one of two identical containers, and another adult (the communicator) observed the hiding process and attempted to help the participant by placing a marker on the container that she believed to hold the reward. An initial series of control trials ensured that participants were able to use the marker to locate the reward, follow the reward in both visible and invisible displacements, and ignore the marker when they knew it to be incorrect. In the crucial false belief trials, the communicator watched the hiding process and then left the area, at which time the hider switched the locations of the containers. When the communicator returned, she marked the container at the location where she had seen the reward hidden, which was incorrect. The hider then gave the subject the opportunity to find the sticker. Successful performance required participants to reason as follows: the communicator placed the marker where she saw the reward hidden; the container that was at that location is now at the other location; so the reward is at the other location. Children were also given a verbal false belief task in the context of this same hiding game. The two main results of the study were: (1) children's performance on the verbal and nonverbal false belief tasks were highly correlated (and both fit very closely with age norms from previous studies), and (2) no ape succeeded in the nonverbal false belief task even though they succeeded in all of the control trials indicating mastery of the general task demands.  相似文献

The effects of systematically varied teacher verbal and nonverbal evaluative behavior upon student willingness to self-disclose were studied within an experimental microlesson. Subjects were 126 sixth-grade students who were removed from their classrooms to participate in a vocabulary lesson with one of the four experimental teachers (two male and two female). Within each experimental condition, the teacher employed one of four evaluative styles: (1) verbally and nonverbally positive, (2) verbally positive and nonverbally negative, (3) verbally negative and nonverbally positive, or (4) verbally and nonverbally negative. The data analysis indicated that teachers' verbal behavior influenced self-disclosure. The magnitude of student self-disclosure scores was a direct function of the positiveness of teacher verbal behavior. Nonverbal behavior also influenced self-disclosure, interacting with student sex. This effect varied across individual teachers, however, and no consistent pattern was evident.  相似文献

Abstract

The writer (Ogletree) conducted a creativity study in England, Scotland, and Germany, which included 1,165 primary school children. Results showed that creativity scores (using the Torrance Tests of Creative Thinking) were a function of socioeconomic background. In all countries, children of upper class families obtained significantly higher creativity scores (verbal and nonverbal) than children of middle and lower class families. The same significant difference was evident in middle class children to lower class children. This was true when analyzed within countries, by age, grade, and sex. There was no evidence to support the contention that youngsters of lower class backgrounds performed better on nonverbal tasks than their higher class peers, although they did make a better showing on the nonverbal tasks than on the verbal tasks.  相似文献

Teaching supports the high-fidelity transmission of knowledge and skills. This study examined similarities and differences in caregiver teaching practices in the United States and Vanuatu (N = 125 caregiver and 3- to 8-year-old child pairs) during a collaborative problem-solving task. Caregivers used diverse verbal and nonverbal teaching practices and adjusted their behaviors in response to task difficulty and child age in both populations. U.S. caregivers used practices consistent with a direct active teaching style typical of formal education, including guiding children’s participation, frequent praise, and facilitation. In contrast, Ni-Vanuatu caregivers used practices associated with informal education and divided tasks with children based on difficulty. The implications of these findings for claims about the universality and diversity of caregiver teaching are discussed.  相似文献

Imagery deficits in nonverbal learning disabilities   总被引：6，自引：0，他引：6  
This study reports the observations gathered from 11 children referred to consulting services because of learning difficulties at school and diagnosed with nonverbal learning disabilities (NVLD). These children had an average verbal IQ, but a WISC-R performance IQ lower than the verbal IQ by at least 15 points and experienced difficulties especially in mathematics and drawing. The children completed a battery of four tasks requiring visuospatial working memory and visual imagery: a memory task composed of pictures and their positions (Pictures task), a task that required them to memorize the positions filled in a matrix (Passive Matrix task), a task that required them to imagine a pathway along a matrix (Active Matrix task) and a task that required them to learn groups made up of three words, using a visual interactive imagery strategy (TV task). In comparison to a control group of 49 children, children with NVLD scored lower in all the tasks, showing deficits in the use of visuospatial working memory and visual imagery. By contrasting subgroups of children of different ages in the control group, it was possible to show that some tasks did not show a clear developmental trend. Thus the deficits shown by the children with NVLD cannot simply be attributed to a developmental delay of these children, but seem to reflect a more severe disability.  相似文献

This study investigated children's choices of deliberate practice strategies. Six-to 11-year-olds (n = 85) were presented with three outwardly similar motor tasks that varied only in the precision of the motor response required to succeed. Children then had the opportunity to practice these tasks before a “test” in which they had to complete all three tasks in the fastest overall time. While children of all ages spent relatively more time practicing the hardest task, only 10- and 11-year-olds scored more successes on the hardest task than the other tasks during the initial practice period. After verbal instruction, however, children of all ages scored more successes on the hardest task during practice, and younger children became more likely to persevere with the hardest task rather than switching tasks after a success. Children's practice choices may vary as a function of age and verbal instruction.  相似文献

A nonexperimental design was used to determine whether the verbal scores of low-income gifted fifth graders (n = 38) differed from those of their higher income peers (n = 83). The Otis–Lennon School Ability Test, Eighth Edition and the Stanford Achievement Test-Tenth Edition were used to collect student data. Results of a MANOVA showed a statistically significant difference between the verbal scores of the two groups, with low-income students scoring significantly lower. A large effect size for the multivariate main effect of income level on verbal intelligence and verbal achievement scores was found (η2 = .19). The existence of verbal–nonverbal score discrepancy in low-income students questions the practice of using only nonverbal or nonverbal parts of an IQ test to identify and place students in gifted programmes. These results also underscore the need to nurture underdeveloped verbal abilities when they occur in low-income students.  相似文献

We investigated in a pilot study the effects of various types of visual mediation (photos, written words and self‐paced syllabic segmentation of written words displayed on a touchscreen tablet) that are thought to facilitate the oral production of nonverbal and minimally verbal children with autism, according to the participants’ level of oral language development and, more specifically, their ability to produce delayed echolalia. We also sought to identify the cognitive characteristics that need to be taken into account when seeking to develop the oral production of nonverbal children with autism. Results showed that the nonverbal and minimally verbal children with autism were able of using written words to produce them orally. Their performance was largely dependent on their level of language development. Tasks combining written and oral modalities prompted some of them to engage in oral production for the first time (isolated syllables for nonverbal children) and allowed others to produce non‐random strings of syllables (minimally verbal children).  相似文献

This study investigates the creative abilities of children with learning disabilities by employing a new measure designed to assess creativity without the use of verbal or analytic skills. Sixteen normally performing and 16 children with learning disabilities were administered this task and a control task of verbal fluency. The children with learning disabilities scored significantly higher on the nonverbal but not the verbal control task.  相似文献

A paradigm of specialized brain hemisphere processing abilities was used to test cognitive skills and cognitive style in "learning-disabled" (LD) and "normal" children. Results indicate that (1) verbal ability is not a unitary factor, and LD children are deficient in only some aspects of verbal ability; (2) the LD group perform as well as the control group on right-hemisphere tests; (3) LD boys are more field sensitive (field dependent) than the control boys; (4) LD children may be attempting to use a nonverbal information processing mode to deal with academic tasks. The need for information on nonverbal processing skills in order to aid verbal processing is discussed.  相似文献
