“…Regarding the frontal part of the network commonly associated with ordinal processing tasks, although some studies have shown sensitivity to ordinal distance of middle and inferior frontal gyri, this seems to be the case only for ordinal judgment tasks requiring more explicit, controlled judgments (e.g. serial order WM and alphabetic ordinal judgment) but not in numerical ordinal judgment which can rely on the more automatic activation of numerical information (Fulbright et al 2003;Attout et al 2014Attout et al , 2015.…”

The Neural Representation of Ordinal Information: Domain-Specific or Domain-General?

Ordinal processing allows for the representation of the sequential relations between stimuli and is a fundamental aspect of different cognitive domains such as verbal working memory (WM), language and numerical cognition. Several studies suggest common ordinal coding mechanisms across these different domains but direct between-domain comparisons of ordinal coding are rare and have led to contradictory evidence. This fMRI study examined the commonality of ordinal representations across the WM, the number, and the letter domains by using a multivoxel pattern analysis approach and by focusing on triplet stimuli associated with robust ordinal distance effects. Neural patterns in fronto-parietal cortices distinguished ordinal distance in all domains. Critically, between-task predictions of ordinal distance in fronto-parietal cortices were robust between serial order WM, alphabetical order judgment but not when involving the numerical order judgment tasks. Moreover, frontal ROIs further supported between-task prediction of distance for the luminance judgment control task, the serial order WM, and the alphabetical tasks. These results suggest that common neural substrates characterize processing of ordinal information in WM and alphabetical but not numerical domains. This commonality, particularly in frontal cortices, may however reflect attentional control processes involved in judging ordinal distances rather than the intervention of domain-general ordinal codes.

“…In the memory assessment, there was lower performance of the group with dyscalculia and dyslexia in short-term auditory memory when compared to the non-case group. Studies indicate that this result is expected when these groups are compared to children without difficulties (Attout et al, 2015;Bogaerts et al, 2014). In short-term visual memory, no differences were found among any of the groups.…”

“…In addition, deficits in other neuropsychological abilities may secondarily track these major impairments, such as attention, Executive Functions (EF) and memory, both in dyslexia (Bogaerts, Szmalec, Page, & Duyck, 2014;Menghini et al, 2010;Ziegler, Pech-Georgel, Dufau, & Grainger, 2010) and in dyscalculia (Ashkenazi, Rubinsten, & Henik, 2009;Attout, Salmon & Majerus, 2015).…”

This paper aims to compare the neuropsychological and educational profiles of Brazilian children with dyscalculia (n = 8), dyslexia (n = 13) and without learning disabilities (n = 12). The neuropsychological profile was composed of: (a) intelligence - assessed by the Wechsler Intelligence Scale for Children (WISC-III); (b) attention - WISC-III Coding and Symbol Search subtests; (c) executive functions - Digit Span (backward order) and WISC-III Arithmetic subtests, Pseudoword Repetition Test for Brazilian Children, Stroop Test and Wisconsin Card Sorting Test; (d) memory - WISC-III Digit Span subtest (forward order) and Rey Complex Figures. The educational profile was composed of reading, writing and mathematics, assessed by the Academic Performance Test and the Arithmetic Test. It was found that the groups with dyscalculia and dyslexia did not differentiate in any of the neuropsychological abilities, only in the reading and writing abilities. Neuropsychological variables that could explain these results were discussed.

“…In kindergarten children, a longitudinal study (Attout et al ., ) showed that a WM task maximizing maintenance of serial order information predicted calculation abilities one and 2 years later while this was not the case for WM tasks requiring only the maintenance of item information (defined as a temporary activation of phonological and semantic representation of the information). Furthermore, neurodevelopmental studies also revealed a specific deficit to maintain serial order information in WM in individuals presenting with a history of developmental dyscalculia (Attout & Majerus, ; Attout, Salmon, & Majerus, ; De Visscher, Szmalec, Van Der Linden, & Noël, ).…”

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. Statement of contribution What is already known on this subject? Numerical ordinal processes predict mathematical achievement in adults. Order WM processing predicts first mathematical abilities. What the present study adds? Numerical ordinal processes predict mathematical achievement in children and independently of order WM. The link between order WM and mathematical abilities was mediated by long-term ordinal processes.
