The field of ‘embodied’ perception reflects the fact that our perception of the world is malleable. Perception is scaled by our available resources. Major demographic factors of health, sex, age and weight all influence our resources. This project will investigate the effects of physiological resources on perception relevant to walking for transport, a current public health approach to increase physical activity at the population level. Walking is one of the most energetically costly human behaviours. Survival requires that energy expenditure should not commonly exceed energy consumption. As a result, we naturally minimize the cost of walking, using information from the visual world that informs us about the energetic cost of potential actions. For example, women avoid stairs more than men because they require a greater proportion of a woman’s available resources relative to man of the same weight. This avoidance is unlikely to be driven by conscious processes but rather by implicit biases resulting from our evolutionary past. This project will investigate signals relevant to walking for transport, concentrating on perception of hills and stairs in the field and in the laboratory.
Individuals who avoid stairs perceive them as steeper than those who choose to climb them (Eves et al., 2014). Further, this perception scales by physiological resources for climbing. Women, older pedestrians and the overweight are more likely to avoid climbing stairs and report them as steeper than their comparison groups (Eves, 2014: Eves et al., 2014). Paradoxically, the individuals who would benefit more from increased lifestyle physical activity are deterred from this behavioural choice by their perception. This project directly addresses signals relevant to the public health aim of increased physical activity as part of daily life. Its origins are in evolutionary biology.

Familiarity with laboratory research, perceptual psychology, the physiology of physical activity would all be advantageous but are not essential. Familiarity with psychology would be the most advantageous. It is likely that only individuals with a 1st Class degree, or those expected to achieve this level, would be considered. A relevant MSc might be advantageous but is not essential.
