Abstract: BACKGROUND: The literature discussing visual ergonomics often
mention that human vision is adapted to light emitted by the sun. However,
theoretical and practical implications of this viewpoint is seldom discussed or
taken into account. OBJECTIVE: The paper discusses some of the main theoretical
implications of an evolutionary approach to visual ergonomics. DISCUSSION: Based on interactional theory and ideas from ecological
psychology an evolutionary stress model is proposed as a theoretical framework
for future research in ergonomics and human factors. The model stresses the
importance of developing work environments that fits with our evolutionary
adaptations. In accordance with evolutionary psychology, the environment of
evolutionary adaptedness (EEA) and evolutionarily-novel environments (EN) are
used as key concepts. Using work with visual display units (VDU) as an example,
the paper discusses how this knowledge can be utilized in an ergonomic analysis
of risk factors in the work environment. CONCLUSION: The paper emphasises the importance of incorporating
evolutionary theory in the field of ergonomics. Further, the paper encourages
scientific practices that further our understanding of any phenomena beyond the
borders of traditional proximal explanations.
