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.

It has been suggested that mathematics learning disabilities, including those of genetic origin, result from a basic impairment of quantitative representations. In Williams syndrome (WS) in particular, latest studies report a specific deficit in tasks requiring symbolic and non-symbolic numerical magnitude processing (Krajcsi et al., 2009 ; O’Hearn & Landau, 2007; Paterson et al., 2006). However, non-numerical quantitative processing has never been investigated and contradictory evidence has been reported about their ability to subitize small collections(Ansari et al., 2007; O’Hearn et al., 2005, 2011). Moreover, as patients with WS were always tested in the visual modality, it remains unclear whether their deficit is specific to the processing of numerical magnitude or result from their basic visuo-spatial impairment, which is a main characteristic of the WS cognitive phenotype. Therefore, numerical and non-numerical acuity were assessed in a group of patients with WS using quantitative comparison tasks with different visuo-spatial processing requirements. Participants were asked to compare: (1) the length of two sticks (spatial dimension) vs. the duration of two sounds (temporal dimension) to assess non numerical quantitative processing, (2) the numerosity of two visual arrays (spatial arrangement) versus two sequences of flashs (no spatial processing) to assess non-symbolic numerical processing, and (3) two Arabic numbers vs two Spoken verbal numerals to examine the access to symbolic number meaning. They also had to enumerate sets of 1 to 7 dots shown for 250 ms to explore their subitizing abilities. Results indicate that participants with WS are impaired in quantitative tasks requiring the processing of visuo-spatial dimension(s) (i.e. comparison of lengths or collections) but not in a visual task requiring processing numerosities with no spatial processing component (i.e. numerical comparison of sequences of flashs). They also present difficulties in accessing the meaning of numerical symbols whatever the format and present smaller subitizing range. [less ▲]

Supporting the second hypothesis, a first study showed that people with WS have lower numerical acuity only in numerical tasks with high visuo-spatial processing requirements (i.e. comparing two lengths or two arrays of elements but not when comparing two durations or two sequences of flash in a single location; Rousselle et al., 2013). Recently, we tested whether a similar dissociation would be observed in processing the meaning of numerical symbols. Patients with WS were asked to compare the numerical magnitude of two Arabic d vs two spoken verbal numerals. Their subitizing abilities were also assessed through the enumeration of 1 to 7 dots shown for 250 ms. Participants with WS were compared to children matched on verbal or nonverbal mental abilities. Results show that they have difficulties in accessing the meaning of numerical symbols whatever the format and present smaller subitizing [less ▲]

Therefore, numerical and non-numerical acuity were assessed in a group of 20 patients with WS using quantitative comparison tasks with different visuo-spatial processing requirements. They were compared to 40 typically developing children, half of them matched on verbal mental age and the other half matched on nonverbal mental age. Participants were asked to compare: (1) the length of two sticks (spatial dimension) vs. the duration of two sounds (temporal dimension) to assess non numerical quantitative processing, (2) the numerosity of two visual arrays (spatial arrangement) versus two sequences of flashs (no spatial processing) to assess non-symbolic numerical processing, and (3) two Arabic numbers vs two Spoken verbal numerals to examine the access to symbolic number meaning.

The main objective of the current study was to examine the impact of two child risk factors, i.e. personality and inhibition, and two proximal family risk factors, i.e. parenting and attachment, and the impact of their cumulative effect on later externalizing behavior among young children incurring no distal family risk. Data were collected in a longitudinal two-wave design from 161 non-referred and referred children aged three to five years at the onset of the study. All of the children were raised in families of middle to high socioeconomic status, i.e. their parents were educated to a middle to high level, had access to the job market and lived together as couples. The four risk domains were assessed at the onset of the study, while EB was rated both at the onset of the study and in the 24-month follow-up. Results confirmed that the four risk domains were each both correlates of EB and efficient at discriminating non-referred from referred children; that their combination regardless of their content (cumulative risk) provided a strong prediction of both later EB and non-referred vs referred sample membership. The results are discussed both for research and clinical purposes. [less ▲]
