Process-oriented intelligence research: A review from the cognitive perspective

Despite over a century of research on intelligence, the cognitive processes underlying intelligent behavior are still unclear. In this review, we summarize empirical results investigating contribution associated with working memory capacity, processing speed, and executive to intelligence differences. Specifically, (a) evaluate how three different domains have been measured, (b) these related individual differences in intelligence. Consistently, review illustrates that isolating single using average performance tasks is hardly possible. Instead, formal models implement theories may provide more adequate indicators processes. Therefore, outlined which for specific insights into Finally, discuss implications process-oriented measurement psychometric argue model-based approach might overcome validity problems traditional theories. • The remain elusive.
