Attentional and executive function behaviours in children with poor working memory

The purpose of this study was to explore the profiles of classroom behaviour relating to attention and executive functions in children with very poor working memory, and to test the hypothesis that inattentive behaviour and working memory problems co-occur. Teachers rated problem behaviours of 52 children with low working memory scores aged 5/6 and 9/10 years on teacher rating measures of attention and executive function behaviours. The majority of children with low working memory scores obtained atypically high ratings of cognitive problems/ inattentive symptoms, and were judged to have short attention spans, high levels of distractibility, problems in monitoring the quality of their work, and difficulties in generating new solutions to problems. These results extend previous findings that working memory problems and inattentive behaviour co-occur to a non-clinical sample. It is suggested that reduced working memory capacity may play a causal role in the problem behaviours of these children.     

Short-term memory and working memory in children as a function of language-specific knowledge in English and Spanish

This study determined the degree to which the phonological and executive components of memory reflect language-specific capacities in Spanish and English vocabulary. We tested whether the memory processes in a sample of English language learners found in Grade 1 also emerged in Grade 2. For the total sample (N = 90), Grade 1 English STM measures shared a common construct with Spanish STM, whereas Grade 2 STM measures were language dependent. In contrast, WM measures were language independent across grades 1 and 2. When vocabulary subgroups were analyzed, a subgroup × type of memory task emerged. The results showed that performance on Spanish and English STM tasks were a function of high and low Spanish and English vocabulary knowledge, whereas WM was not. The relationship between language-specific processes in memory was discussed.     

Executive functions in learning processes: Do they benefit from physical activity?

As executive functions play an essential role in learning processes, approaches capable of enhancing executive functioning are of particular interest to educational psychology. Recently, the hypothesis has been advanced that executive functioning may benefit from changes in neurobiological processes induced by physical activity. The present research explored this hypothesis by systematically identifying and reviewing intervention studies targeting the relationship between physical activity and executive functions, distinguishing between different types of intervention and of executive function. The review found considerable evidence for beneficial effects of physical activity on executive functions, with performance benefitting more consistently in inhibition tasks than in dual task coordination, shifting tasks, or combined tasks. Possible physiological explanations are discussed. Open questions for application and future research concern the sustainability of effects, the design of physical activity interventions, and the role of individual differences. Possible interventions applicable to educational settings are discussed.

The Relations Between Children’s Reading Comprehension, Working Memory, Language Skills and Components of Reading Decoding in a Normal Sample

The primary aim of the current study was to identify the strongest independent predictors of reading comprehension using word reading, language and memory variables in a normal sample of 180 children in grades 3–5, with a range of word reading skills. It was hypothesized that orthographic processing, receptive vocabulary and verbal working memory would all make independent contributions to reading comprehension. The contributions of reading speed, receptive grammatical skills, exposure to print, visuospatial working memory and verbal learning and retrieval (a measure of longer-term retention) were also investigated. Working memory tasks that required the processing and storage of numerical and spatial material were used. One of the numerical working memory tasks was based on the number span task developed by Yuill, Oakhill, and Parkin British Journal of Psychology, 1989, 80, 351–361. A visuospatial equivalent of that task was developed from the forward Corsi block task [Corsi, Abstracts International, 1973, 34, 891]. The results revealed that, after controlling for age and general intellectual ability, the word reading and the language variables had a much stronger relation with reading comprehension than the memory variables. The strongest independent predictor of reading comprehension was orthographic processing since it captured variance in both word reading, language skills and verbal working memory. The forward Corsi task and performance on a measure of verbal learning and retrieval each made small independent contributions to reading comprehension but the contribution of verbal working memory was not significant. It was concluded that tasks measuring the interplay between short-term and long-term memory, in which new information is combined with information already stored in long-term memory, may better predict reading comprehension measured with the text available than working memory tasks which only have a short-term memory component.     

Contribution of Working Memory Capacity to Children’s Reading Comprehension: A Longitudinal Investigation

We examined the contribution of working memory capacity to the development of children’s reading comprehension. We present data from three waves of a longitudinal study when the children were 7 years (Grade 1), 8 years (Grade 2) and 9 years (Grade 3). Two questions were raised: The first question concerned the developmental changes of the relative contribution of working memory in predicting reading comprehension compared to vocabulary and decoding skills. The second question explored to what extent reading comprehension could be predicted by working memory capacity measured at a prior time. At the end of each grade, reading comprehension, nonword reading, vocabulary knowledge and working memory capacity were assessed. To test the first question, the predictive power of working memory capacity was compared to vocabulary and decoding skills by performing concurrent multiple-regression analyses in each grade. The results showed that working memory capacity emerged as a direct predictor of reading comprehension in Grade 3. To address the second question, we performed multiple-regression analyses predicting reading comprehension from working memory, nonword reading, and vocabulary measured at a prior time. In these analyses, the autoregressive effect was taken into account to separately assess the unique contribution of each predictor to the development of later reading comprehension. The results showed that Grade 1 vocabulary and Grade 2 working memory had additional effects on Grade 3 reading comprehension after the autoregressive effect of reading comprehension had been accounted for. These findings support the idea that, as word recognition becomes automated throughout the early grade levels, working memory becomes an important determinant of reading comprehension. There is also evidence that working memory capacity directly influences the development of reading comprehension skills. The direction of the causal flow is discussed.     

Distinctive patterns of relationship of phonological awareness and working memory with reading development

The purpose of this study was to assess the contributions of specific components of verbal and nonverbal working memory and of phonological awareness to the prediction of reading achievement. One hundred and three children from grades 1, 2, and 3 were administered a measure of phonological awareness, four measures of working memory, four measures of academic achievement, and a measure of verbal intelligence. Separate multiple regression analyses controlling for the effects of age, sex and verbal intelligence showed that tests of verbal memory and of direct recall significantly predicted reading and spelling achievement whereas tests of backward recall significantly predicted only pseudoword identification. Phonological awareness was also found to relate significantly to reading and spelling achievement even when working memory was partialled out. Thus, phonological awareness and measures of working memory predicted specific and significant amounts of variance in reading and spelling achievement. Further, none of these measures were specifically related to arithmetic achievement. The specific roles of phonological awareness and working memory in reading development are examined in the discussion.

Reading comprehension difficulties in children

This paper reports two studies investigating the nature of comprehension deficits in a group of 7–8 year old children whose decoding skills are normal, but whose reading comprehension skills are poor. The performance of these poor comprehenders was compared to two control groups, Chronological-Age controls and Comprehension-Age controls. The first study examined whether these comprehension difficulties are specific to reading. On two measures of listening comprehension the poor comprehenders were found to perform at a significantly lower level than Chronological-Age controls. However, they did not differ from a group of younger children matched for reading comprehension skills. This indicates that the observed comprehension difficulties are not restricted to reading, but rather represent a general comprehension limitation. The second study investigated whether these comprehension difficulties can be explained in terms of a memory deficit. The short-term and working memory skills of these three groups were examined. The poor comprehenders did not differ from their Chronological-Age controls on either of these tasks. In conclusion, it is argued that working memory processes are not a major causal factor in the creation of the comprehension difficulties identified in the present group of poor comprehenders.     

Cross‐ and mono‐linguistic text processing in bilingual children

Bilingual German fourth‐graders are expected to develop greater linguistic awareness than monolingual children and therefore should habitually apply different text‐processing strategies compared with German monolingual fourth‐graders when comprehending and recalling a text. Bilingual children are expected to process texts from the bottom up, from the text base to the gist, whereas monolingual children should engage in top‐down processing, which is indicated, for example, by more text intrusions and inferences. This research attempts to clarify whether bilinguals show this shift in direction of processing when they process cross‐linguistic versus mono‐linguistic texts. The results of Experiment 1 supported our main hypothesis. Monolingual German fourth‐graders had more intrusions than same‐aged German–English (L1–L2) bilingual children. In Experiment 2, nearly balanced German–English and German‐dominant children were tested separately in within‐language free recall in both languages and in across‐language text recall. For nearly balanced bilingual children, within‐ and cross‐language recall was equally efficient in both languages but not for German‐dominant bilingual children – in their recall, more intrusions appeared in their L2 recall. Top‐down processing seems to increase when it is in the weaker language. Engaging in bottom‐up processing apparently is associated with cognitive functioning in L1.

Developmental associations between verbal and visual short-term memory and the acquisition of decoding skill

This study longitudinally investigated the relationships between verbaland visual short-term memory (STM) and the acquisition of decoding from thepre-reading through the early acquisition stages in 63 Hebrew-speakingchildren Test waves occurred in kindergarten, first grade and second grade.IQ, visual and verbal STM and decoding ability were assessed. The dataindicated that while both verbal and visual STM in kindergarten were significantlycorrelated to later decoding skill, pre-reading visual STM was a stronger predictor.The results further showed that pre-reading performance on the WISC-R BlockDesign test predicted later decoding ability, while performance on theWISC-R Vocabulary test did not. Lastly decoding skill in grade 1 was foundto predict only visual in grade 2. These results indicate that visualparameters may make a crucial contribution to the acquisition of decodingskills. The size of pre-reading visual STM capacity appears to play a rolein this process. The relationship between visual STM and decoding may bebidirectional, as learning to decode appears to develop visual STM. It issuggested that either language-related or task-related factors may accountfor these counter-to-mainstream results.
