Symbolic and situational mathematics are the two major representations of mathematical knowledge. Although previous literature has studied the relationship between the two from the perspective of teaching practice, learning effectiveness and behavioural performance, there is still a lack of empirical psychological research on cognitive mechanisms to explore the psychological processes of the two. The current study investigated the relationship between symbolic and situational mathematics by determining the differences in cognitive correlates between the two in fourth‐grade children. Their symbolic and situational mathematics abilities were assessed using symbolic and situational enumeration tests under the same conditions. Several types of general cognitive abilities, language processing and academic achievements were also examined. Results showed that both situational and symbolic mathematics are crucial for mathematical achievement. Arithmetic computation is closely correlated with symbolic mathematics, whereas spatial processing and inductive reasoning ability are uniquely correlated with situational mathematics. The results suggest that situational and symbolic mathematics have separate cognitive correlates, which means the two are distinct in terms of psychological processing. [ABSTRACT FROM AUTHOR]

Objectives: The 'attentional spotlight' can be adjusted depending on the task requirements, resulting in processing information at either the local or global level. Stroke can lead to local or global processing biases, or the inability to simultaneously attend both levels. In this study, we assessed the (1) prevalence of abnormal local and global biases following stroke, (2) differences between left- and right-sided brain damaged patients, and (3) relations between local and global interference, the ability to attend local and global levels simultaneously, and lateralized attention, search organization, search speed, visuo-construction, executive functioning, and verbal (working) memory. Methods: Stroke patients admitted for inpatient rehabilitation completed directed (N = 192 total; N = 46 left-sided/ N = 48 right-sided lesion) and divided (N = 258 total; N = 67 left-sided/ N = 66 right-sided lesion) local–global processing tasks, as well as a conventional neuropsychological assessment. Processing biases and interference effects were separately computed for directed and divided tasks. Results: On the local–global tasks, 7.8–10.9% of patients showed an abnormal local bias and 6.3–8.3% an abnormal global bias for directed attention, and 5.4–10.1% an abnormal local bias and 6.6–15.9% an abnormal global bias for divided attention. There was no significant difference between patients with left- and right-sided brain damage. There was a moderate positive relation between local interference and search speed, and a small positive relation between global interference and neglect. Conclusions: Abnormal local and global biases can occur after stroke and might relate to a range of cognitive functions. A specific bias might require a different approach in assessment, psycho-education, and treatment. [ABSTRACT FROM AUTHOR]

- Abstract
Previous work has suggested a different developmental timeline and role of visual experience for the use of spatial and non-spatial features in haptic object recognition. To investigate this conjecture, we used a haptic ambiguous odd-one-out task in which one object needed to be selected as being different from two other objects. The odd-one-out could be selected based on four characteristics: size, shape (spatial), texture, and weight (non-spatial). We tested sighted children from 4 to 12 years of age; congenitally blind, late blind, and adult participants with low vision; and normally sighted adults. Given the protracted developmental time course for spatial perception, we expected a shift from a preference for non-spatial features toward spatial features during typical development. Due to the dominant influence of vision for spatial perception, we expected congenitally blind adults to show a similar preference for non-spatial features as the youngest children. The results confirmed our first hypothesis; the 4-year-olds demonstrated a lower dominance for spatial features for object classification compared with older children and sighted adults. In contrast, our second hypothesis was not confirmed; congenitally blind adults' preferred categorization criteria were indistinguishable from those of sighted controls. These findings suggest an early development, but late maturation, of spatial processing in haptic object recognition independent of visual experience., (Copyright © 2024 The Author(s).

Navigation skills are essential for independent living as they allow us to explore our environment; find our way to new locations, refine pathways to familiar locations and retrace our route home. Alongside motor coordination difficulties, there is evidence that individuals with Developmental Coordination Disorder (DCD/Dyspraxia) experience spatial processing difficulties, which are known to negatively affect navigation abilities. However, although self-reports indicate that adults with DCD have difficulties with sense of direction and navigation, no known studies have measured navigation abilities and strategies in adults with DCD. Furthermore, given evidence that individuals with DCD report higher levels of anxiety, we will additionally investigate associations between anxiety and navigation in this group. This study compares navigation abilities, navigation strategies and spatial anxiety in adults with and without DCD. Participants include 226 Adults aged 18–55 years, across two groups 1) DCD (N = 138, 111 F:25 M; 2:Other) 2); Typically Developing (N = 88, 77 F: 11 M). In this cross-sectional study, participants completed a series of tasks on the online Qualtrics platform. This included the Adult Developmental Coordination Disorder Checklist, the State-Trait Anxiety Inventory, the Wayfinding Anxiety Measure, the Wayfinding Questionnaire, the Wayfinding Strategy Questionnaire, and a navigation task. Our analysis shows that 1) compared to those with typical development, individuals with DCD have similar navigation performance but lower navigation and orientation scores, and distance estimation scores. 2) Movement co-ordination difficulties were only a significant predictor of landmark recognition and egocentric path route knowledge, and played no role for other aspects of navigation performance. 3) For wayfinding strategy use the DCD group used orientation strategies significantly less often than those with typical development, however there was no group difference in the use of route strategies. 4) The DCD group had significantly higher spatial anxiety scores across navigation, manipulation and imagery spatial sub-domains, even after controlling for general anxiety. 5) Spatial navigation anxiety was a significant predictor of navigational skill for all three wayfinding measures (navigation & orientation, distance estimation and spatial anxiety). The findings establish benchmarks of navigational skills in DCD and highlight spatial anxiety and route strategies as factors that may inhibit navigation success and could help specify suitable intervention targets. • This was the first study to investigate navigational abilities in adults with DCD. • Compared to controls, individuals with DCD have similar navigation performance but lower navigation and orientation scores, and distance estimation scores. The DCD group had higher spatial anxiety scores across navigation, manipulation and imagery spatial sub-domains. • Navigational difficulty in DCD extends across multiple domains, and greater difficulty is positively associeted with movement difficulty. • Findings establish benchmarks of navigational skills in DCD; spatial anxiety, orientation and route strategies are factors inhibiting success.
