Attention is a cognitive process that enables the selection and focus on relevant stimuli from the environment, filtering out irrelevant information to facilitate perception, comprehension, and action. In the context of the built environment, attention is influenced by spatial, sensory, and environmental characteristics, shaping how people experience and relate to the city.
