Recent studies have demonstrated that both ordinal number processing and serial order working memory (WM) abilities predict calculation achievement. This raises the question of shared ordinal processes operating in both numerical and WM domains. We explored this question by assessing the interrelations between numerical ordinal, serial order WM, and arithmetic abilities in 102 7- to 9-year-old children. We replicated previous studies showing that ordinal numerical judgement and serial order WM predict arithmetic abilities. Furthermore, we showed that ordinal numerical judgement abilities predict arithmetic abilities after controlling for serial order WM abilities while the relationship between serial order WM and arithmetic abilities was mediated by numerical ordinal judgement performance. We discuss these results in the light of recent theoretical frameworks considering that numerical ordinal codes support the coding of order information in verbal WM. [less ▲]

Il semble plutôt évident que lorsque nous réalisons une opération arithmétique nous devons maintenir de manière temporaire le premier opérande en vue de l’utiliser ultérieurement ou encore maintenir pendant un court laps de temps le résultat intermédiaire d’un calcul complexe. De la même façon, dans le comptage verbal, il est nécessaire de maintenir temporairement l’élément qui vient d’être compté afin de pouvoir déterminer l’élément suivant. Alors que la plupart des études s’accordent pour montrer un déficit de l’administrateur central chez des enfants présentant un trouble spécifique des apprentissages en mathématiques, l’altération de la mémoire à court terme (MCT) verbale et visuo-spatiale reste beaucoup plus discutée. Néanmoins, la plupart des recherches ayant exploré le lien entre MCT et dyscalculie développementale ne tiennent pas compte des récentes études comportementales, en neuroimagerie et des modélisations de la MCT distinguant le traitement de l’information « item » et « ordre » en MCT. Nous présenterons donc une série d’études dans le développement normal et atypique démontrant l’importance du traitement de l’ordre sériel en MCT dans le développement des habiletés mathématiques. Enfin, nous discuterons de la pertinence de la prise en charge des composants d’ordre sériel en MCT dans les troubles d’apprentissage des habiletés mathématiques. [less ▲]

Some previous studies showed that verbal short-term memory (STM) is better preserved than visuospatial STM in the velocardiofacial syndrome (VCFS), a neurodevelopmental disorder resulting from a 22q11.2 deletion. This deficit is generally assigned to a more global visuospatial skills deficit. However, for verbal STM, previous study suggested a specific deficit in the serial order component, processing considered as independent of modalities. In this study we proposed to explore the serial order component in visuospatial STM by contrasting simultaneous vs. sequential presentation of stimuli to maintain in children with VCFS, in order to see in what extent the deficit is global and resulting from visuospatial deficit or whether this deficit is specific to the serial order component. We tested a group of 27 children and adolescents with VCFS to a control group, matched on verbal IQ performance estimated. The VCFS group showed impaired performance on the sequential configuration but similar performance on the simultaneous condition. These results support the idea of an amodal serial order component in STM. The implication of serial order STM deficits on numerical cognition will be discussed. [less ▲]

Most studies on early magnitude representation focused on the visual modality with no possibility to disentangle the influence of visuo-spatial skills and short-term memory (STM) abilities on visual quantification processes. In order to specify the influence of visuo-spatial and STM processing on numerical abilities, a series of magnitudes comparison tasks differing on visuo-spatial processing requirement (no/high), on the nature of the magnitude to be processed (continuous/discrete/symbolic magnitude) and on WM demands (simultaneous/sequential presentation) were administred to twenty patients with Turner syndrome (TS), a genetic condition characterized by poor mathematical achievement, low spatial skills and reduced STM abilities. Our results showed a lower acuity than a control group matched on verbal IQ when participants with TS compared the numerical magnitudes of stimuli presented sequentially (low visuo-spatial processing and high STM load: Dot sequence and Sound sequence). No difference was observed in the numerical comparison of sets presented simultaneously or when comparing continuous and symbolic magnitude stimuli. Besides, the group difference in sequential tasks disappeared when controlling for STM abilities. These results highlight the importance of STM abilities to extract numerosity through a sequential presentation and underline the importance of considering the impact of format presentation on magnitude judgments.

Several studies suggest a close link between the development of working memory (WM) and numerical abilities. The aim of this study was to determine whether working memory training may facilitate the acquisition of early numerical skills. Past training studies exploring this question have led to inconclusive results. Here we present two training studies in kindergarten and first grade children focusing on either general WM training or on serial order WM training, the latter component having been recently shown to predict early arithmetic abilities. Both training procedures failed to lead to specific increases of various mathematical skills as compared to a control training group. These results will be discussed in the light of the inconclusive results of past training studies, and we will identify methodological caveats for future training studies on working memory and numerical development.
