“…Primarily, functional affordances are related to specific site-specific features: hence, the functional affordances of walking, running, cycling, and playing ball are related to the presence of flat, void, relatively smooth surfaces. Likewise, the affordances of hiding, prospect, and sitting in are associated with the availability of enclosed spaces, hence, a space bounded on three sides or covered by a ceiling of height not superior than 2.50 m. Finally, rigid features include non-movable features (including trees, retaining walls, benches, and stairs) that afford sitting-on, jumping-on/over/down-from, running around, hiding behind, or building on [14,17,19,37].…”
