Participants were Academic performance examined on executive control processes, reasoning in several domains, self-evaluation of performance in these Cognition domains, and language. Structural equation modelling showed that cognitive and language ability highly pre- Language dicted school performance. These relations changed with age; cognitive flexibility, working memory and rea- Cognitive development soning dominated from 9 to 11 and reasoning and language dominated from 13 to 15 years. Self-evaluation was Intelligence related with academic performance only in secondary school, but this relation was masked by reasoning. SES influenced school achievement directly on top of cognitive influences in both primary and secondary school.The implications for cognitive developmental theory and educational implications are discussed. 1.

We decomposed this relation into specific number, identity, and degree of functional autonomy of the domains processes involved in cognition, such as executive control, reasoning, are still disputed, some domains are recognized across disciplines of language and cognitive self-evaluation, and specified if they relate to psychological research. For instance, spatial, categorical, quantitative, school performance differently at different levels of school education. causal, social, and verbal reasoning emerged as distinct domains in Below we first summarize current research about the organization and differential, cognitive, developmental, and educational psychology development of these mental processes. We then summarize research (Carroll, 1993; Case, 1992; Case, Demetriou, Platsidou, Kazi, 2001; showing how these processes relate to academic achievement. Finally, Demetriou & Spanoudis, 2018; Gardner, 1983; Thurstone, 1973). we state predictions to be tested by our study. At still a higher level, all domains relate to a higher-order factor, general intelligence or g, reflecting the fact that all mental processes 1.1. Intelligence correlate with each other. Although widely accepted, the nature of g is still under strong dispute. Through the years, it has been associated 1.1.1. Organization with three types of domain-independent processes.
