he map shows some of the data from our ongoing experiment in Vancouver. Each dot shows a stop on our walk and the average response of a group of participants who were tested at that location. The colour and size of the dot indicates the type of response, measured from 1 to 5: take a look the scale below and you’ll notice that the dot becomes larger and more red the closer to 5 the collective answer was. You can see these values on the map by using the ‘question’ buttons. Each button reveals the question asked (on the right) and the layer of the map shows each stop on the walk with the colour coded answers given by participants.
We also measure values of brain and physiological processing during the walk. We use cognitive tasks to asses how the brain is behaving. Collectively, all of the variables that are geocoded on the map help us to develop a neuroscientific and psychological profile of the effect of city streets on the average human observer. We can use this information to test hypotheses, plan new experiments, or even to identify psychological problem locations in the urban landscape.
