The role of speed of processing, rapid naming, and phonological awareness in reading achievement

This study investigated the role of speed of processing, rapid naming, and phonological awareness in reading achievement. Measures of response time in motor, visual, lexical, grammatical, and phonological tasks were administered to 279 children in third grade. Measures of rapid object naming, phonological awareness, and reading achievement were given in second and fourth grades. Reading group comparisons indicated that poor readers were proportionally slower than good readers across response time measures and on the rapid object naming task. These results suggest that some poor readers have a general deficit in speed of processing and that their problems in rapid object naming are in part a reflection of this deficit. Hierarchical regression analyses further showed that when considered along with IQ and phonological awareness, speed of processing explained unique variance in reading achievement. This finding suggests that a speed of processing deficit may be an "extraphonological" factor in some reading disabilities.     

The role of inhibitory functioning in children’s reading skills

Executive functions, including inhibition, have been implicated in children’s reading ability. This study investigates whether children’s performance on an inhibition task is more indicative of reading ability than a measure of another executive function, that is, planning. Fifty‐three male participants were administered a reading test and tests of inhibition and planning not requiring a verbal response. Regression analyses revealed that only inhibition significantly predicted reading. Previous inconsistencies may reflect the modality of the tasks used to measure inhibition. Therefore non‐verbal measures may have highest utility for educational psychologists.     

Attention deficit disorder with and without hyperactivity: reaction time and speed of cognitive processing

This study addressed the issue as to whether children reliably diagnosed as attention deficit disordered with hyperactivity (ADD/H) and without hyperactivity (ADD/WO) differed significantly from each other and a clinic control (CC) population on speed and efficiency of cognitive processing. From an outpatient clinic population, 43 ADD/H and 22 ADD/WO children were examined. An analysis of mean reaction time and speeded classification task performance revealed significant group effects on both mean reaction time and on a measure of within-subject variability. ADD/H children performed significantly more slowly and variably than the CC children on several of the speeded classification tasks. However, the ADD/WO group was not distinguished on any measure. Thus, while children may be reliably diagnosed as ADD/H or ADD/WO using behavioral measures, it would appear that they cannot be distinguished on these neurocognitive tasks. Issues related to childhood psychopathology and the neuropsychological basis of ADD/H are discussed.     

The role of numerical and non-numerical ordering abilities in mathematics and reading in middle childhood

This study investigated whether different types of ordering skills were related to mathematics achievement in children (n = 100) in middle childhood, after the effects of age, socio-economic status, IQ, and processing speed were taken into account. The relations between ordering skills and magnitude processing were also investigated, as well as the possibility that some of the shared variance between math and reading is explained by ordering abilities. The ordering tasks included the ordering of familiar numerical and non-numerical sequences, a parental report of children’s everyday ordering skills, and an order working memory task. Three magnitude processing tasks (symbolic and non-symbolic comparison and number line estimation), were also administered, as well as measures of inhibition and spatial working memory. From this set of measures, number ordering, order working memory and number line estimation emerged as the most important predictors of mathematics skills. We found that number ordering mediated the effect of both symbolic and non-symbolic comparison skills on mathematics, further confirming that this task captures some essential skills related to mathematics. Additionally, order working memory mediated the effect of both number comparison and reading skills on math. Finally, whereas non-symbolic comparison and number line estimation are considered important indicators of magnitude processing skills, there was no relationship between these abilities, but there was a correlation between each of these abilities and reading skills, with number line estimation also mediating the effect of reading skills on math. These novel findings could contribute to a better understanding of the basic processes underlying math ability, and why math and reading are strongly related in typical populations and in children with learning difficulties.     

Do different components of working memory underlie different subgroups of reading disabilities?

The purpose of this study was to determine the components of working memory (WM) that underlie less skilled readers' comprehension and word recognition difficulties. Performance of 3 less skilled reading subgroups---children with reading disabilities (RD) in both word recognition and comprehension; children with comprehension deficits only; and children with low verbal IQ, word recognition, and comprehension (poor readers)--was compared to that of skilled readers on WM, short-term memory (STM), processing speed, executive, and phonological processing measures. Ability group comparisons showed that (a) skilled readers outperformed all less skilled readers on measures of WM, updating, and processing speed; (b) children with comprehension deficits only outperformed children with RD on measures of WM, STM, phonological processing, and processing speed; and (c) children with RD outperformed poor readers on WM and phonological processing measures. A hierarchical regression analysis showed that (a) subgroup differences on WM tasks among less skilled readers were moderated by a storage system not specific to phonological skills, and (b) STM and updating contributed significant variance to WM beyond what was contributed by reading group classification. The latter finding suggested that some differences in storage and executive processing emerged between skilled and less skilled readers that were not specific to reading.     

Balance Among Cognitive Control Processes: A Case Study of a Gifted Youth

This case study analyzed the cognitive strategies of Ethan, a gifted youth, when performing a Stop Signal Task assessing cognitive control processes including response inhibition as well as proactive and reactive adjustments of response. In the case of Ethan, the response inhibition score was biased, revealing that Ethan did not follow the instructions but challenged them and was successful in doing this. Specifically, he made important proactive adjustments, by both slowing down and speeding up (i.e., risk taking) his responses according to the likelihood of the apparition of the stop signal (triggering response inhibition). Ethan’s performance indicated that he perfectly understood the procedure behind the task and completed it according to his own comprehension. Ethan’s results showed that researchers and clinicians must be careful when assessing gifted children and adolescents by using tasks that they cannot defeat.     

Experiences of a gifted and talented enrichment cluster for pupils aged five to seven

There has been an increased commitment to gifted and talented education in the UK in recent years, with a national strategy of grant-funded programmes. However, research into the effective-ness of gifted programmes is relatively limited. This paper, written by Anne Morgan of the Centre for Education and Inclusion Research at Sheffield Hallam University, investigates parents', teachers' and children's experiences and views of the impact of an enrichment programme for gifted and talented pupils aged five to seven. Methods included a survey of mainstream teachers (n = 15), interviews with parents (n = 17) and activities with pupils (between 16 and 24 children). Results showed that children and parents rated the cluster highly, particularly the varied teaching styles and interaction with other gifted children. There were few concerns regarding withdrawal of children from school in order to attend. All parents felt that their children had benefited from attending and around half said there had been an impact on their social and academic development. Similarly, around half of mainstream teachers said that attending the cluster had benefited children socially and academically.     

Inquiry learning for gifted children

The aim of the study was to investigate the effects of support on knowledge acquisition of gifted learners and their flow and mood during inquiry learning. Sixty-four gifted primary school children were randomly assigned to one of three conditions differing in support given in an inquiry task. Results showed that learners who were allowed to experiment themselves learned more, experienced more flow, and felt more positive toward the task than those who were not given this opportunity, but only when they were guided through the inquiry cycle by prompts to generate hypotheses, perform experiments, and draw conclusions. The overall conclusion is that gifted children benefit more from open, complex tasks when their learning process is externally regulated.     

Rapid Naming Components and Their Relationship With Phonological Awareness,Orthographic Knowledge,Speed of Processing,and Different Reading Outcomes

This study examines (a) how rapid automatized naming (RAN) speed components—articulation time and pause time—predict reading accuracy and reading fluency in Grades 2 and 3, and (b) how RAN components are related to measures of phonological awareness, orthographic knowledge, and speed of processing. Forty-eight children were administered RAN tasks in Grades 1, 2, and 3. Results indicated that pause time was highly correlated with both reading accuracy and reading fluency measures and shared more of its predictive variance with orthographic knowledge than with phonological awareness or speed of processing. In contrast, articulation time was only weakly correlated with the reading measures and was rather independent from any processing skill at any point of measurement.     

Intellectually gifted rural-to-urban migrant children’s attention

The term “intellectually gifted rural-to-urban migrant children” refers to intellectually gifted children who are in migration from rural to urban areas. We compared performances on seven attention tasks among intellectually gifted (n = 26) and average (n = 30) rural-to-urban migrant and intellectually gifted urban children (n = 31). Our results showed that intellectually gifted rural-to-urban migrant children performed more correctly and faster on some attention tasks than did the intellectually average rural-to-urban migrant children, but they did not perform as well on some attention tasks as did the intellectually gifted urban children. Based on the attentional structures, it was evident the intellectually gifted rural-to-urban migrant children developed more mature than did either the intellectually gifted urban or the intellectually average rural-to-urban migrant children. This suggests the intellectually gifted rural-to-urban migrant children’s attention is overall superior to that of their intellectually average peers. However, there are advantages and disadvantages in terms of the quality of their attention compared to the intellectually gifted urban children. While their attentional structures seem to develop earlier, their accuracy on some of the attention tasks seems to suffer. This suggests that rural-to-urban migration is a double-edged sword for intellectually gifted children.     

Effects of Self-Concept on Learning with Gifted Children

Abstract

The present study examined die influence self-concept played in a verbal free recall and non-verbal paired associate learning task with gifted children. Twenty-four male and 24 female pre-adolescents were divided into high and low self-concept groups for each sex, forming four groups with 12 subjects in each group. A 20-item free recall task and a five-trial, six-item non-verbal paired associate learning task were administered. High self-esteem boys and girls showed significantly greater mastery of all learning tasks than lower self-concept counterparts. Analysis of organization scores supported the use of more sophisticated learning strategies by children with higher self-perceptions.     

Theory of mind,executive function and social competence in boys with ADHD

Abstract

Twenty-two boys with a diagnosis of ADHD were com-KEYWORDS pared with 22 typically developing boys on an advanced theory of mind task and on two tasks measuring aspects of executive function. Parents completed rating forms measuring general social competence, as well as mentalizing and non-mentalizing social behaviours. There were no differences between the groups on the advanced theory of mind measure.The children with ADHD scored more poorly than controls on an inhibition task but not on a planning task once age and IQ had been covaried. Ratings of social competence were correlated with theory of mind and executive function ability for the typically developing controls but not for the children with ADHD. The results are discussed in terms of inhibitory and social information processing accounts of ADHD.     

Role of working memory in explaining the performance of individuals with specific reading comprehension difficulties: A meta-analysis

It is well established that working memory is related to reading comprehension ability. However, its role in explaining specific reading comprehension difficulties is still under debate: the issue mainly concerns whether the contribution of working memory is dependent on task modality (verbal tasks being more predictive than visuo-spatial tasks) and/or on the attentional control implied in working memory tasks (tasks requiring storage/manipulation being more predictive than storage-only tasks, regardless of task modality). Meta-analysis is used here to examine the relevance of several working memory measures in distinguishing between the performance of poor and good comprehenders in relation to the modality of the working memory task, and the involvement of controlled attention required by such a task. Our results demonstrate that memory tasks that are demanding in terms of attentional control and that require verbal information processing are best at distinguishing between poor and good comprehenders, suggesting that both domain-specific factors as well as general factors of working memory contribute to reading comprehension performance. The implications for different models of working memory in relation to reading comprehension are discussed.     

Gifted children with written output difficulties: Paradox or paradigm

Abstract

This study was designed to ascertain the prevalence of written output deficits in young gifted children, to delineate the relationship between written output performance and reading performance, and to identify possible mechanisms for specific written output deficits in such children. Data from a sample of children scoring >120 on at least one IQ or achievement subscale indicated: (1) that there was a significant incidence of discrepancies between written spelling scores and reading (decoding) scores, as compared to the population; (2) that performance on spelling tasks was more subject to a maturational timetable than decoding was; (3) that performance on spelling tasks is less amenable than performance on decoding tasks to compensatory enhancement by higher level processing, and involves a sequential processing module that is shared with calculation but not with decoding; and (4) that strengths in visual‐spatial tasks may interact with relative weaknesses in both decoding and calculation tasks to predict even poorer performance on written spelling tasks.     

Cognitive scanning processes in children

Third- and fifth-grade children and adults were presented with 8-item letter sequences of varied approximations to English in a tachistoscopic single report, cue delay task. Age differences in report accuracy suggested that younger children, as compared with adults, may be at a double disadvantage in tasks requiring perceptual-memory processing: Their initial intake capacity and/or selective processing abilities may be more limited than those of adults; and the subsequent strategy employed by children to transfer iconic information into a more permanent memory store appears to be qualitatively, as well as quantitatively, different (less systematic, less orderly, and less efficient) than that used by adults. The suggestion that children's reading experience and ability (as assessed by a word recognition task) may be related to their systematic use of an orderly left-to-right iconic transfer strategy was also examined. In addition, the results suggested that the differential letter-pattern familiarity effect between children and adults may not be attributable to visual intake components but, rather, may be related to the relative rates with which familiar letter patterns are transferred out of iconic memory.     

Changes over time and transfer of analogy-problem solving of gifted and non-gifted children in a dynamic testing setting

This study examined differences in transfer of analogical reasoning after analogy-problem solving between 40 gifted and 95 average-ability children (aged 9–10 years old), utilising dynamic testing principles. This approach was used in order to examine potential differences between gifted and average-ability children in relation to progression after training, and with regard to the question whether training children in analogy problem-solving elicits transfer of analogical reasoning skills to an analogy construction-task. Children were allocated to one of two experimental conditions: either children received unguided practice in analogy problem-solving, or they were provided with this in addition to training incorporating graduated prompting techniques. The results showed that gifted and average-ability children who were trained made more progress in analogy problem-solving than their peers who received unguided practice experiences only. Gifted and average-ability children were found to show similar progression in analogy problem-solving, and gifted children did not appear to have an advantage in the analogy-construction transfer task. The dynamic training seemed to bring about no additional improvement on the transfer task over that of unguided practice experiences only.     

Information processing deficits in children with attention-deficit/hyperactivity disorder, inattentive type, and children with reading disability

We examined the information processing capabilities of children diagnosed with the inattentive subtype of attention-deficit/hyperactivity disorder (ADHD) who had been characterized as having a sluggish cognitive tempo. Children referred for school-related problems (n = 81) and nonreferred community controls (n = 149) participated. Of the referred children, 24 met criteria for ADHD, 42 met criteria for reading disability (RD), and 9 of these were comorbid for RD and ADHD. Children with ADHD differed from those without ADHD on a visual search task but not on an auditory processing task; the reverse was true for children with RD. Decomposition of the visual search task into component operations demonstrated that children in the ADHD group had a slow processing rate that was not attributable to inattention. The children with ADHD were not globally poor at information processing or inattentive, but they demonstrated diminished speed of visual processing.     

Recent doctoral dissertation research on gifted

The objective of this study was to determine whether electrophysiologic techniques can be used to identify central auditory processing difficulties in low‐achieving gifted adolescents. The electrophysiologic measures utilized included the middle latency response and the P300 response. These measures were obtained from four groups: achieving‐gifted, low‐achieving gifted, learning disabled, and non‐gifted non‐disabled. It was found that P300 wave morphology was significantly poorer for the low‐achieving gifted group compared to the achieving gifted and the non‐gifted non‐disabled groups. There was no significant difference between the low‐achieving gifted group and the learning disabled group.     

Memory and Speed: Their Role in the Relation of Infant Information Processing to Later IQ

This study examined the extent to which memory and processing speed accounted for relations we had found earlier between infant information processing and childhood IQ. The measures of speed and memory were obtained when the children were 11 years of age using paper-and-pencil tasks and an extensive battery of computer-administered tasks. The relations of 7 month visual recognition memory and 1 years cross-modal transfer to 11 years IQ were both substantially reduced with statistical control of factors dericed from these measures. These results suggest that speed and memory underlie some of the infant-childhood continuities in cognition. Path and stuctural equation modeling indicated that the significant pathways from 7 month visual recognition memory to 11 year IQ were nboth directr and indirect, the indirect paths going through memory and speed.     

Strategic and nonstrategic factors in gifted children's free recall

The present experiment contrasted the recall of gifted and nongifted middle-school children for sets of categorically related items. Subjects were given a single free-recall trial on each of two lists consisting of category-typical and category-atypical words. The typicality of the items for one list was based on each subject's unique typicality ratings, whereas the typicality of the items in the second list was based on adult norms. A preliminary category-rating task indicated that gifted students were somewhat more similar to adults in their ratings of category typicality than nongifted children. Recall was comparable between the gifted and nongifted subjects for typical items, but greater for the gifted subjects for atypical items. The latency between the recall of unrelated words was faster for the gifted than the nongifted children. Subjects were classified as strategic or nonstrategic on the basis of clustering and interitem latencies. Gifted subjects were less apt to be classified as strategic than nongifted subjects on the typical items of the self-generated list; there were no differences in the classification between the gifted and nongifted children for all other contrasts. These results were interpreted as indicating that the cognitive advantage of gifted relative to nongifted children is more apt to be in terms of nonstrategic rather than strategic functioning.
