Previous studies have shown that children with Developmental Coordination Disorder (DCD)/Dyspraxia have poorer maths performance compared to their neurotypical (NT) counterparts. However, no studies ...have explored the cognitive and emotional factors affecting the maths performance of adults with DCD. This study, therefore, investigated the role of working memory (WM), maths anxiety (MAS), and maths self-efficacy on the maths performance of adults with DCD. We found that adults with DCD had lower WM and maths performance and were more maths anxious than their NT peers. However, there were no significant differences in maths self-efficacy. When looking at the predictors of maths performance, we found a positive relationship between WM resources and the DCD maths performance, possibly indicating that they relied more on WM resources to perform simple mental arithmetic tasks than NTs. On the other hand, MAS had an inverse relationship with the NT maths performance but not with the DCD performance. The reasons and implications of these findings will be discussed.

Learning to drive is a significant event for the transition to adulthood and delay or avoidance may have social, practical, and psychological implications. For those with Developmental Coordination ...Disorder (DCD/Dyspraxia), driving presents a considerable challenge, and the literature shows that there are differences in driving ability between individuals with and without DCD. The aim of the current research is to further our understanding of the mechanisms underlying the driving experiences of individuals with DCD. Nineteen participants with DCD (10 drivers and 9 non-drivers) and 36 controls (17 drivers and 19 non-drivers) aged 18-57 years took part in this study. Participants completed standardized tests, questionnaires and a driving simulation task designed to measure speed, road positioning, and rate of change of steering in three conditions with increasing perceptual complexity. Results indicate that behaviors for all participants changed as the perceptual demands of the task increased. However, drivers with DCD were more affected than all other groups, driving more slowly, and driving further to the right. These findings illustrate how the impact of both internal and external constraints negatively affect the success of the driving task for individuals with DCD compared to their TD peers.
Developmental Coordination Disorder (DCD), also known as dyspraxia, affects 5-15% of school-aged children (Hamilton and Sutton, Am Fam Physician 66:1435, 2002) and significantly impacts a child's ...ability to learn motor skills and perform everyday activities efficiently and effectively (Zwicker et al., Eur J Paediatr Neurol 16:573-81, 2012). These motor deficits can have a negative impact on academic performance, vocational choices and leisure pursuits (Zwicker et al., Eur J Paediatr Neurol 16:573-81, 2012) and profoundly impact quality of life (Izadi-Najafabadi et al., Res Dev Disabil 84:75-84, 2019). DCD persists into adulthood (Kirby et al., J Adult Dev 18:107-13, 2011), impacting motor as well as emotional and behavioural status (Tal Saban and Kirby, Curr Dev Disord Rep 5:9-17, 2018). Despite the continued increase in research in the field of DCD, awareness of DCD remains poor (O'Kelly NL., From invisibility to invincibility: Guidelines for supporting families through the diagnosis and journey with developmental coordination disorder, 2012) even though it has higher prevalence rates when compared to, for example, autism spectrum disorder (Yan et al., J Autism Dev Disord :1-7, 2024), which in part may be due to a lack of accessible research findings. A fundamental feature of the research process is disseminating research findings. This should involve community members in design and delivery to ensure the accessibility of research findings.
This qualitative study explored the childhood experiences of growing up with a sibling with Developmental Coordination Disorder (DCD) to offer an ‘outsider’s’ view of this condition. Ten individuals ...who had grown up with a sibling with DCD were interviewed about their experiences. Data were analysed using Thematic Analysis. Analysis described three main themes: i)‘witnessing the challenges for their sibling with DCD’ ii) ‘experiencing the impact on the family’; iii) ‘a vacuum of knowledge’. Not all experiences were negative and transcending these themes was the notion ‘resolution and finding benefit’ highlighting access to support, being more empathic and resilient, becoming a role model for others and finding success. Participants play witness to their sibling’s experiences which can often be negative sometimes impacted by a vacuum of knowledge but they also describe how a diagnosis of DCD comes with some benefits which are discussed in the context of ‘posttraumatic growth’.

Developmental Coordination Disorder (DCD) is a movement disorder in which atypical sensory processing may underly movement atypicality. However, whether altered sensory processing is domain-specific ...or global in nature, are unanswered questions. Here, we measured for the first time, different aspects of sensory processing and spatiotemporal integration in the same cohort of adult participants with DCD (N = 16), possible DCD (pDCD, N = 12) and neurotypical adults (NT, N = 28). Haptic perception was reduced in both DCD and the extended DCD + pDCD groups when compared to NT adults. Audio-visual integration, measured using the sound-induced double flash illusion, was reduced only in DCD participants, and not the DCD + pDCD extended group. While low-level sensory processing was altered in DCD, the more cognitive, higher-level ability to infer temporal dimensions from spatial information, and vice-versa, as assessed with Tau-Kappa effects, was intact in DCD (and extended DCD + pDCD) participants. Both audio-visual integration and haptic perception difficulties correlated with the degree of self-reported DCD symptoms and were most apparent when comparing DCD and NT groups directly, instead of the expanded DCD + pDCD group. The association of sensory difficulties with DCD symptoms suggests that perceptual differences play a role in motor difficulties in DCD via an underlying internal modelling mechanism.
•Adults with DCD and with pDCD demonstrate poorer haptic perception.•Only adults with DCD exhibited atypical audio-visual integration.•These perceptual alterations correlated with self-reported DCD symptoms.•Ability to infer temporal dimensions from spatial information was preserved in DCD.

Humans are highly social creatures who use others' movements to evaluate their social competencies. Smooth movement specifically signals an attractive, trustworthy or competent person. Those with ...Developmental Coordination Disorder (DCD), have peer relationship difficulties and lower sociometric preference scores. However, the relationship of perception of poor movement coordination to stereotyping has not been directly demonstrated.
We aimed to describe typically developing individuals' social stereotyping of individuals with and without DCD from minimal visual cues.
3D motion capture tracked the movement of four ‘targets’ (two adult males with DCD and two male controls) in a variety of everyday scenarios. Kinematic footage of the target's movements was presented as a point-light-display to 319 typically developing adults who used The Rating Scale of Social Competence to report perceptions of the target's social competencies.
Targets with DCD were rated as having significantly lower social competence (M = 3.37, SD = 0.93) than controls (M = 3.46, SD = 0.89) t(269) = −5.656; p < 0.001, Cohen's d = 0.34.
Humans incorporate minimal information on movement fluency to evaluate others' social competencies, including individuals with DCD. Such stereotyping may be automatic and may be an ill-understood mechanism sustaining persistent rejection by peers for individuals with DCD and higher rates of loneliness, isolation and mental disorders. In addition, our study expands research on competence-based stereotyping to a new applied domain, confirming the minimal cues needed to initiate stereotyping of the competencies of others.
Two paradigms were employed to disentangle information processing from executive motor inhibition in adults with Developmental Coordination Disorder (DCD). Choice Reaction and Stop Signal Tasks were ...compared between 13 adults fulfilling DSM-5 DCD criteria and 42 typically developing adults. Additional analyses included 16 probable DCD (pDCD) participants, who had motor difficulties but did not fulfil DSM-5 criteria. Analyses employed frequentist and Bayesian modeling. While DCD+pDCD showed slower reaction times and difficulty initiating Go responses, no impairments in Stop actions were found. These findings indicated no executive deficit in DCD, suggesting that previous results may be explained by inefficient information processing.
