Given our pattern of results we come back to the discussion, what factors significantly contribute to academic achievement.
In line with other researches we conclude, that working memory seems to be the more important predictor for
academic achievement: Children with normal intelligence seem to fail at school when their working memory is impaired
(the group with mixed disorders of scholastic skills) and children with low intelligence may succeed well at school as long as
their working memory is unimpaired (the “overachievers”). This conclusion is supported by other findings, which suggest,
“that the specificity of associations between working memory and attainment persist after statistically controlling for differences
in IQ” (Alloway & Alloway, 2010; Alloway, 2007). Furthermore longitudinal studies that predictlater school attainment
from earlier intelligence and working memory functioning strengthen the higher significance of working memory (Alloway
& Alloway, 2010; Preßler, Könen, Krajewski, & Hasselhorn, 2014).
