Abstract

Semantic cognition refers to our ability to use, manipulate and generalize knowledge that is acquired over the lifespan to support innumerable verbal and non-verbal behaviours. This Review summarizes key findings and issues arising from a decade of research into the neurocognitive and neurocomputational underpinnings of this ability, leading to a new framework that we term controlled semantic cognition (CSC). CSC offers solutions to long-standing queries in philosophy and cognitive science, and yields a convergent framework for understanding the neural and computational bases of healthy semantic cognition and its dysfunction in brain disorders.

Semantic Knowledge Memory Systems

Definition

Semantic cognition is the ability to use, manipulate and generalize knowledge acquired over the lifespan, and the controlled semantic cognition framework separates the stored conceptual knowledge itself from the control processes that retrieve and shape it for a given task
