Description
Summary:This viewpoint explores the gap between theoretical frameworks in experimental neuroscience and clinical neuropsychology. It highlights how John Duncan's theory of the Multiple Demand (MD) system, which links the frontal lobe to fluid intelligence (g), helps explain general performance on classical executive tests. However, it also discusses how traditional scores often fail to capture the complexity of behaviours associated with frontal lobe damage, and we suggest that developing improved scoring methods could be useful for integrating experimental and clinical neuropsychology insights. •We integrate research findings on frontal lobe and clinical neuropsychology.•We relate fluid intelligence to the Multiple Demand system.•We discuss how fluid intelligence affects performance on executive tests.•We show how executive test scores fail to reflect complex behaviors.•We suggest developing better scoring methods for executive tests.
