The Visual Field Is A Bounded Region

What It Brings
A variant of the container metaphor for vision, but with a crucial structural difference: the visual field is an area with edges rather than an enclosure with walls. Things do not move “in” and “out” so much as they extend to or beyond the boundaries. The metaphor emphasizes the extent and limits of what can be seen rather than the threshold of visibility.
Key structural parallels:
- Edges rather than walls — the visual field has a periphery, not a boundary you cross. “The crowd extends out to the very edges of my field of vision.” Objects are at the edge, near the edge, or beyond it — a matter of distance from the center, not of being inside or outside.
- Extension and reach — the visual field has a range. “Peripheral vision.” “The huge crowd extends beyond my field of vision.” The metaphor treats seeing as reaching: how far does your visual field extend?
- Center and periphery — unlike the container metaphor, which primarily distinguishes inside from outside, the bounded region metaphor distinguishes center from edge. “Central vision” vs. “peripheral vision” maps onto center vs. boundary of a region.
- Gradation — a bounded region admits of degrees in a way a container does not. Objects can be more or less central, more or less peripheral. This maps better onto the actual gradient of visual acuity, which is sharpest at the fovea and degrades toward the edges.
The Osaka archive credits this entry to Jane Espenson and lists sub-mappings: “Within Sight Is Within Region” and “Out Of Sight Is Out Of Bounded Region.”
Where It Breaks
- Regions are static; the visual field moves — a bounded region suggests a fixed area on a map. The visual field moves with every saccade, head turn, and body rotation. The metaphor captures the shape of visual experience at a frozen moment but not its dynamism.
- The boundary is not sharp — even “bounded region” overstates the crispness of the visual periphery. Vision does not end; it fades. Peripheral vision degrades in acuity and color sensitivity but never reaches a clean edge. The metaphor imposes a boundary where biology provides a gradient.
- The metaphor blurs with the container version — the Osaka archive itself notes this: “BOUNDED REGIONS ARE CONTAINERS? How could we tell?” Many expressions work for both metaphors (“field of vision,” “out of sight”). The distinction is real but hard to maintain in ordinary language, which suggests the two metaphors may be aspects of a single underlying schema.
- “Field” does double duty — “field of vision” uses “field” in the sense of an open area (bounded region), but “field” also means a domain of study or activity (a different metaphor entirely). The ambiguity can blur spatial and conceptual uses.
Expressions
- “The crowd extends out to the very edges of my field of vision” — visible extent as reaching the boundary of a region
- “Peripheral vision” — the edge of the bounded region, where acuity degrades
- “The huge crowd extends beyond my field of vision” — exceeding the boundary of the visible region
- “Field of vision” — the visible area as a spatial expanse with edges
- “Range of sight” — how far the bounded region extends
- “Sweep of vision” — the angular extent of the region
- “In my line of sight” — the central axis of the bounded region
- “The horizon” — the ultimate boundary of the visual region, where earth and sky impose a limit
Origin Story
Lakoff and Johnson discuss this metaphor in Chapter 6 of Metaphors We Live By alongside THE VISUAL FIELD IS A CONTAINER. The two metaphors coexist for the same target domain — visual perception — and this coexistence is itself theoretically significant. It demonstrates that a single experience can be structured by multiple metaphors simultaneously, each highlighting different aspects. The container version emphasizes the in/out threshold; the bounded region version emphasizes extent and edges.
The Osaka archive attributes this entry to Jane Espenson (a researcher in the UC Berkeley Cognitive Linguistics Group that compiled the Master Metaphor List) and includes the archive’s own reflexive note questioning whether bounded regions and containers can be distinguished.
