[What We Learn through Multitasking: From Working Memory to General Intelligence].

Abstract

Multitasking ability has become indispensable in modern information-based societies. However, the question whether interindividual variations in multitasking ability can serve as a strong predictor of working memory performance and even general intelligence has received less attention. This review initially explores how these three seemingly disparate cognitive components-which operate at different levels-are interrelated and, then, critically examines the "brain training" boom of the 2000s that was characterized by claims that multitasking training could enhance general intelligence.
