Abstract Two meta-analyses assessed whether the relations between reading and mathematics outcomes could be explained through overlapping skills (e.g., systems for word and fact retrieval) or domain-general influences (e.g., top-down attentional control). The first (378 studies, 1,282,796 participants) included weighted random-effects meta-regression models to explore and contrast the magnitudes of the links between dif-ferent reading and mathematical competencies. The second (138 studies, 39,836 par-ticipants) used meta-analytic structural equation modeling to determine the influence of a domain-general factor, defined by intelligence, executive functioning, working and short-term memory, and processing speed measures, on the link between read-ing and mathematics skills. The overall relation was significant (r=0.52), as were all associations between specific reading and mathematics measures (rs = 0.23 to 0.61, ps<.05). Most of the correlations were similar across different types of reading and mathematics competencies, although generally smaller than within-domain correla-tions. The domain-general model explained most of the covariance between reading and mathematics outcomes, with a few modest moderating effects (e.g., age). The results imply correlations between reading and mathematics measures are largely due to domain-general processes, although within-domain correlations confirm the importance of overlapping competencies especially for reading.

Abstract
Digital game-based training programs have recently been used to train the cognitive abilities of children with neurodevelopmental disorders (NDDs). However, the effects of training remain controversial. The present meta-analysis explored the effectiveness of digital game-based training in children with NDDs and examined the possible moderators of its effects. Twenty-nine studies with cognitive outcomes in 1535 children were included in the present meta-analysis. The results showed that digital game-based training could significantly enhance the core cognitive abilities of children with each type of NDDs and that training could be used remotely. Meanwhile, task content and game features of digital game-based interventions separately make unique and significant contributions to the training effects, suggesting that the combination of training content and game features could efficiently improve children's cognition. Although the present study revealed that the training benefits could be maintained over a period of time, more studies are needed to explore the retention effects of digital game-based training. The present study provides a comprehensive understanding of the training effects of digital game-based interventions and new insights for future cognitive training design and application.
