Abstract: Svenson, O. & Hedenborg, M. L. 1980. Counting processes in simple addition. Scandinavian Journal of Education Research 24,93‐104. Verbal protocols and response latencies were used in this study to investigate the thought processes used by children solving simple arithmetic problems (I + J = , where 0≤I≤13 and 0< J ≤13). To specify, the verbal reports were used to classify the solutions into one of two main groups: (a) answers retrieved from long term memory and (b) answers involving active manipulation of the problem in working memory (reconstructive solutions). The response latencies in each of these groups were analyzed separately for each child. As expected, latencies for retrieved answers were shorter than for reconstructed solutions. The retrieval from long term memory of the answer to a problem with the smaller number first (e.g., 3+4) required about 0.1 sec longer time than when the numbers were in the reverse order (4 + 3). Grouping latencies according to verbal protocols made it possible to refine the analysis of the response latencies. To exemplify, counting strategies with greater units than one (e.g., 6 + 4: 6, 8, 10) were identified and parameters describing the cognitive processes listed.  相似文献

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic.  相似文献

Individual differences in infant attention are theorized to reflect the speed of information processing and are related to later cognitive abilities (i.e., memory, language, and intelligence). This study provides the first systematic longitudinal analysis of infant attention and early childhood executive function (EF; e.g., working memory, inhibitory control, cognitive flexibility). A group of 5‐month‐olds (n = 201) were classified as short or long lookers. At 24, 36, and 48 months of age, children completed age‐appropriate EF tasks. Infant short lookers (i.e., more efficient information processors) exhibited higher EF throughout early childhood as compared to infant long lookers, even after controlling for verbal ability (a potential indicator of intelligence). These findings are discussed in relation to the emergence of executive attention.  相似文献

Gestures, hand movements that accompany speech, affect children's learning, memory, and thinking (e.g., Goldin‐Meadow, 2003). However, it remains unknown how children distinguish gestures from other kinds of actions. In this study, 4‐ to 9‐year‐olds (n = 339) and adults (n = 50) described one of three scenes: (a) an actor moving objects, (b) an actor moving her hands in the presence of objects (but not touching them), or (c) an actor moving her hands in the absence of objects. Participants across all ages were equally able to identify actions on objects as goal directed, but the ability to identify empty‐handed movements as representational actions (i.e., as gestures) increased with age and was influenced by the presence of objects, especially in older children.  相似文献

Do typical arithmetic problems hinder learning of mathematical equivalence? Second and third graders (7–9 years old; N= 80) received lessons on mathematical equivalence either with or without typical arithmetic problems (e.g., 15 + 13 = 28 vs. 28 = 28, respectively). Children then solved math equivalence problems (e.g., 3 + 9 + 5 = 6 + __), switched lesson conditions, and solved math equivalence problems again. Correct solutions were less common following instruction with typical arithmetic problems. In a supplemental experiment, fifth graders (10–11 years old; N= 19) gave fewer correct solutions after a brief intervention on mathematical equivalence that included typical arithmetic problems. Results suggest that learning is hindered when lessons activate inappropriate existing knowledge.  相似文献

Abstract:Langset, M., Midtvedt, T. & Omland, T. 1981. Differences between Toxoplasma Gondii Infected and Non‐Infected Blind and Partially Sighted Children and Adolescents on WISC and WAIS Verbal Subtests. Scandinavian Journal of Educational Research 25,141‐157. Toxoplasmosis is one of the most prevalent infections of man and animal throughout the world. The Dye Test, (DT), which is assumed specific for an infection of Toxoplasma gondii, was performed on 137 blind and partially sighted children and adolescents in Norway. The rate of DT‐pos., 53 %, correlated with a control group on the level of P ≤0.001, (x2‐test). The infected group was compared with the non‐infected on WISG and WAIS verbal subtests. The results gave the DT‐pos. group lower performances on all verbal subtests. Retesting after five years gave for the DT‐pos. group compared with the DT‐neg. IQ, differences on the level of significance P ≤,0.004. The differences were mainly due to low performances on all subtests, particularly on Comprehension, Similarities, and Digit Span. The impairment was comparable to subjects with brain damage. Subjects with congenital sight deficiency and positive DT showed progressive intellectual impairments.  相似文献

This study examined the relation of 3‐year core information‐processing abilities to lexical growth and development. The core abilities covered four domains—memory, representational competence (cross‐modal transfer), processing speed, and attention. Lexical proficiency was assessed at 3 and 13 years with the Peabody Picture Vocabulary Test (PPVT) and verbal fluency. The sample (N = 128) consisted of 43 preterms (< 1750 g) and 85 full‐terms. Structural equation modeling indicated concurrent relations of toddler information processing and language proficiency and, independent of stability in language, direct predictive links between (a) 3‐year cross‐modal ability and 13‐year PPVT and (b) 3‐year processing speed and both 13‐year measures, PPVT and verbal fluency. Thus, toddler information processing was related to growth in lexical proficiency from 3 to 13 years.  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

Twenty‐nine grade‐matched 4th–8th‐grade males, 12 with attention‐deficit/hyperactivity disorder (ADHD) (age M= 12.2 years, SD= 1.48), and 17 without (age M= 11.5, SD= 1.59), completed two working memory tasks (digit span and the Simon game) and three long‐term episodic memory tasks (a personal event memory task, story memory task, and picture recognition task). In line with clinical observations, children with ADHD performed worse than peers on all working memory tasks, but performed as well as or better than peers on long‐term episodic tasks, demonstrating particularly detailed memory for personally experienced past events. Participants' parents also completed questionnaires about their children's memories in daily life. Parents rated children with ADHD lower than children without ADHD on working and semantic memory (e.g., remembering names, spelling, and math), but rated them as high or higher on memory for events. Implications for theory and educational practice are discussed.  相似文献

Objectives

Adolescents often experience different types of victimization across a specified period of time in different situations. These multiple victimization experiences can have a number of deleterious effects on psychosocial well-being. To expand on research gathered primarily from US samples, the current study estimated the prevalence of multiple victimization in a nationally representative sample of Canadian adolescents. We also expanded on past research by adopting an ecological approach to identify correlates of multiple victimization.

Methods

Cross-sectional data from the 2000-2001 cycle of the National Longitudinal Survey of Children and Youth (NLSCY) were used to estimate the prevalence of multiple victimization (verbal harassment, threat of and actual physical assault, school social exclusion, discrimination) in 1,036 13-16 year olds. We also examined household (e.g., parental education), family (e.g., parenting practices), and adolescent (e.g., friendship quality) correlates of multiple victimization for the whole sample and separately by sex.

Results

Among the 6 in 10 adolescents who reported at least 1 victimization experience, 30.5% reported 2 types of victimization whereas 23.7% reported 3 or more types. There was an increased probability of multiple victimization (2 or more types) in adolescents who reported greater parental rejection, who engaged in more frequent out-of-school activities, and who experienced non-victimization adversity. The probability decreased if adolescents reported greater friendship quality.

Conclusions

The clustering of different types of victimization is common among adolescents. For both males and females, a difficult parent-child relationship characterized as rejecting is important when considering risk for multiple victimization, as is the adolescent's functioning outside of the home in the context of friendship quality and involvement in out-of-school activities. Non-victimization adversity (e.g., death of a loved one) also emerged as a significant multiple victimization correlate.

Practice implications

Non-physically invasive types of victimization (although adolescents also endorsed physical assault) are a reality for a number of adolescents. As such, we need to inquire about such experiences as school social exclusion, discrimination, and verbal threats in applied contexts. Moreover, in order to better identify adolescents who may be vulnerable to multiple forms of victimization, we need to adopt an ecological approach that considers individual, family, and household functioning.  相似文献

Students often experience difficulty with attaching meaning to mathematics symbols. Many students react to symbols, such as the equal sign, as a command to “do something” or “write an answer” without reflecting upon the proper relational meaning of the equal sign. One method for assessing equal‐sign understanding is through nonstandard equations (e.g., 3 + 4 = __ + 5) where student answers provide cues about operational or relational interpretation of the equal sign. This study investigated the influence of symbolic and nonsymbolic presentations on a measure of nonstandard equations. A representative sample of 2nd‐grade students (n = 413) solved a set of nonstandard equations presented with symbols (i.e., symbolic) and the same set presented with pictures and stories (i.e., nonsymbolic). Students with and without mathematics difficulty demonstrated significantly higher scores on the nonsymbolic version without mathematics symbols. Results have implications for mathematics assessment and instruction.  相似文献

Most research on dyslexia to date has focused on early childhood, while comparatively little is known about the nature of dyslexia in adolescence. The current study had two objectives. The first was to investigate the relative contributions of several cognitive and linguistic factors to connected‐text oral reading fluency in a sample of adolescents with dyslexia (n = 77). The second was to test the hypothesis that the effect of verbal working memory on connected‐text oral reading fluency is moderated by word‐level skills and/or vocabulary knowledge. The results suggest that many deficits associated with childhood dyslexia remain prominent in adolescence, but the nature of the relationships between key cognitive and linguistic predictors (i.e., word‐level reading, vocabulary, verbal working memory) and reading fluency appear to be different in adolescence. For example, while word‐level skills remain a significant predictor, the strength of the effect is relatively weak. In contrast, the data support an increased role for vocabulary and verbal working memory, including an interaction between these factors. The presence of an interaction can be interpreted as evidence that the influence of verbal working memory on connected‐text oral reading fluency in adolescents with dyslexia depends on individual differences in vocabulary knowledge. These results offer support for the changing nature of dyslexia across development, and suggest that researchers should study dyslexia in adolescents on its own terms, rather than treating it as an extension of reading problems in early childhood.  相似文献

The aim of this study was to compare visual and verbal memory in children with nonverbal learning disability (NLD) using the Children's Memory Scale and to identify the profile of strengths and weaknesses in visual memory abilities. Performance was significantly lower on measures of visual than verbal memory, indicating that children with NLD have deficits in visual memory despite adequate verbal memory. A unique pattern of performance emerged for the visual but not the verbal subtests. Performance on the Faces Immediate subtest was well below average, although other measures of visual memory were within the average range. Hence, it appears that children with NLD have a specific deficit on immediate memory for faces. This facial memory deficit may be linked to a deficit in right hemisphere functioning, which has already been implicated in facial processing and may also be linked with other disorders (e.g., autism spectrum disorder) in which similar facial processing deficits have been documented. More research is needed to further understand the visual memory profile of children with NLD and to inform instruction and remediation.  相似文献

Socioeconomic attainment gaps in mathematical ability are evident before children begin school, and widen over time. Little is known about why early attainment gaps emerge. Two cross-sectional correlational studies were conducted in 2018–2019 with socioeconomically diverse preschoolers, to explore four factors that might explain why attainment gaps arise: working memory, inhibitory control, verbal ability, and frequency of home mathematical activities (N = 304, 54% female; 84% White, 10% Asian, 1% black African, 1% Kurdish, 4% mixed ethnicity). Inhibitory control and verbal ability emerged as indirect factors in the relation between socioeconomic status and mathematical ability, but neither working memory nor home activities did. We discuss the implications this has for future research to understand, and work towards narrowing attainment gaps.  相似文献

ABSTRACT— How do people spell the thousands of words at the tips of their tongues? Are words with regular sound‐to‐letter correspondences (e.g., “blink”) spelled using the same neural systems as those with irregular correspondences (e.g., “yacht”)? By offering novel neuroimaging evidence, we aim to advance contemporary debate about whether people use a single lexical memory process or whether dual mechanisms of lexical memory and sublexical phonological rules work in concert. We further aim to advance understanding of how people read by taking a fresh look at the related yet distinct capacity to spell. During functional magnetic resonance imaging scanning, 12 participants heard low‐frequency regular words, irregular words, and nonwords (e.g., “shelm”) and responded whether a visual presentation of the word was spelled correctly or incorrectly. While behavioral measures suggested some differences in accuracy and reaction time for the different word types, the neuroimaging results alone demonstrated robust differential processing and support a dual‐route model of spelling, with implications for how spelling is taught and remediated in clinical and educational contexts.  相似文献

A meta-analysis was undertaken to reexamine near- and far-transfer effects following working-memory training and to consider potential moderators more systematically. Forty-seven studies with 65 group comparisons were included in the meta-analysis. Results showed near-transfer effects to short-term and working-memory skills that were sustained at follow-up with effect sizes ranging from g = 0.37 to g = 0.72 for immediate transfer and g = 0.22 to g = 0.78 for long-term transfer. Far-transfer effects to other cognitive skills were small, limited to nonverbal (g = 0.14) and verbal (g = 0.16) ability and not sustained at follow-up. Several moderators (e.g., duration of training sessions, supervision during training) had an influence on transfer effects, including far-transfer effects. We present principles for how best to improve working memory through training in the narrow-task paradigm and conjecture how best to improve basic cognitive functions in complex activity contexts.  相似文献
