*2.1. Participants*

Opportunity sampling, through a volunteers list held by the University of She ffield, was used to recruit 24 adult study participants (n = 12 female; n = 12 male) with a mean age of 35 years (range = 21–61 years, standard deviation = 10). Academic sta ff were omitted from invitation to attain a sample without bias towards higher education levels. All participants had normal to corrected-to-normal vision via contact lenses, did not know the intentions of the study at the time of participation, and had previous experience of the streets investigated.
