Which of the following is one of the four fundamental concepts in cognitive neuropsychology?

• A. Modularity
• B. Neurogenesis
• C. Synaptic Pruning
• D. Global Workspace

Answer: (A)

Modularity is the idea that the mind is made up of relatively autonomous modules, each specialized for processing a particular kind of information, such as language, face perception, or spatial reasoning. This view is central in cognitive neuropsychology because it explains why brain damage can produce selective impairments: a person may lose one ability while others remain intact, signaling distinct cognitive systems with separate neural substrates. The pattern of dissociations across different patients and tasks has long supported the notion that cognitive functions are organized into specialized components that interact, rather than being produced by a single undifferentiated system.

Biological processes like neurogenesis and synaptic pruning shape how the brain develops and adapts, but they describe growth and refinement at a neurobiological level rather than how cognitive functions themselves are structured. Global Workspace is a theory about conscious broadcasting and access to information, which speaks to consciousness and widespread availability of information, not the basic architectural organization of cognitive systems. In this sense, modularity stands out as a foundational idea about how cognitive processes are organized and localized within the brain.
