With a diverse sample of community college (CC) students (n = 94), we investigated how the working memory (WM)-math relation may be moderated by aspects of acculturation, including cultural adoption and cultural maintenance. We predicted that higher levels of each of the above acculturation factors would improve math performance by way of reducing WM load (via cognitive load). Conversely, we expected a weaker WM-math correlation at lower levels of acculturation due to the increased variability in cultural factors and the adverse effect of lower acculturation on WM through heightened cognitive load. In this cohort, WM correlated with math performance, but acculturation did not significantly influence this relationship. Neither cultural adoption nor cultural maintenance moderated the WM-math association. Results suggest that individualized educational interventions based on acculturation status alone may not be an effective strategy. Instead, institutions such as schools and governmental agencies may focus on providing a better foundation for educational success by enhancing academic and non-academic support systems to promote equitable educational opportunities for all students. Further research should explore additional individual and/or demographic factors (e.g. socioeconomic status, experiences of discrimination, cultural background) to better understand these complex relations. 

Knowledge of the relations among learners' socio-emotional characteristics and competencies as they engage in mathematics and reading is limited, especially for children with academic difficulties. This study examined the relations between anxiety, motivation, and competence in mathematics and reading, within and across domains, in an academically-diverse set of 8–13-year-old learners ( n = 146). To measure anxiety and motivation across domains, we paired existing measures of math anxiety and reading motivation with researcher-developed analogs for reading anxiety and math motivation. Participants completed standardized assessments of mathematics and reading, anxiety and motivation surveys for math and reading, and a measure of nonverbal cognitive ability. Results showed high internal consistency for all anxiety and motivation scales (Cronbach's alpha = 0.76–0.91). Pearson correlations showed that within and across domains, participants with higher competence had lower anxiety and higher motivation. Higher anxiety was also associated with lower motivation. Regression analyses showed that for both math and reading, within-domain motivation was a stronger predictor of competence than anxiety. There was a unidirectional across-domain relation: socio-emotional characteristics for reading predicted math competence, after accounting for nonverbal cognitive ability, age, gender, and within-domain anxiety and motivation. Results contribute to knowledge of the socio-emotional characteristics of children with and without learning difficulties in association with reading and math activities. Implications of a unidirectional socio-emotional link between the two domains can advance research and theory of the relations among socio-emotional characteristics and competence for academically-diverse learners.
