An interdisciplinary field that applies the principles of neuroscience and cognitive psychology to the design of environments, tools, and work systems to optimize human brain function and minimize cognitive strain. The goal is to maximize mental performance, reduce errors, and enhance the overall well-being of the individual by creating a neurobiologically compatible workspace. This involves tailoring external factors to the inherent limitations and capabilities of the human attention and memory systems. It is a scientific approach to creating a high-performance cognitive environment.
Origin
This term is a modern evolution of traditional ergonomics, which focused primarily on physical comfort and musculoskeletal health, integrating the complex dynamics of the central nervous system. It emerged from the increasing recognition that cognitive load, not just physical strain, is a primary constraint on modern worker performance. The field draws heavily on brain imaging and cognitive load studies.
Mechanism
Neuro-ergonomics operates by reducing the brain’s need to expend energy on filtering distractions, interpreting cluttered visual fields, or compensating for poor sensory input. For example, optimized lighting and soundscapes reduce the burden on the orienting and alerting networks. By minimizing irrelevant sensory and cognitive processing, the prefrontal cortex can allocate a greater percentage of its finite metabolic resources to the core executive tasks, leading to reduced mental fatigue and sustained high-quality focus.
