Organisational efficiency and productivity are often evaluated in terms of tangible assets and resources. However, an equally crucial yet intangible asset that often goes unnoticed is the cognitive performance of the workforce. This is the mental processing capability that enables individuals to make sound decisions, solve problems, and effectively interact with their environment. One of the critical factors influencing cognitive performance is ergonomics, the science of optimising the design of a workspace to enhance human performance.

Ergonomics is not just about physical comfort or reducing the risk of musculoskeletal disorders. It also plays a pivotal role in enhancing cognitive performance. The design and layout of a workspace can significantly affect an individual’s ability to focus, process information, and make decisions. A well-designed workspace can reduce cognitive load, the mental effort required to perform a task. By minimising distractions and unnecessary complexity, it can improve focus and attention. A study by Hedge (2019) found that employees in ergonomically designed workspaces reported less cognitive strain and higher productivity levels.

The role of lighting in workspace ergonomics is another factor that can influence cognitive performance. Adequate lighting can improve visual clarity, reduce eye strain, and enhance mood, all of which positively impact cognitive performance. Conversely, poor lighting can lead to visual discomfort, fatigue, and decreased cognitive performance.

Sound ergonomics can also be a determining factor for cognitive performance. Excessive noise can lead to cognitive overload, impairing focus and memory. On the other hand, a quiet workspace or the use of ambient noise can improve concentration and cognitive performance.

Workspace layout is another crucial element of ergonomics. Open-plan offices, for instance, can lead to increased distractions and stress, thereby reducing cognitive performance. However, providing employees with private spaces or the flexibility to choose their workspace can enhance cognitive performance (De Croon et al., 2005).

The integration of ergonomics and cognitive performance culminates in the concept of cognitive ergonomics. This is a holistic approach that encompasses not just physical comfort but also cognitive wellbeing. It considers how workspace design can support mental processes such as perception, memory, and decision-making, thereby enhancing overall cognitive performance.

In conclusion, optimising ergonomics for cognitive performance is not just about creating a physically comfortable workspace. It involves considering how various factors such as lighting, noise, and workspace layout can influence cognitive processes. This approach can lead to improved cognitive performance, thereby enhancing organisational productivity and efficiency.
