Primes¶
- Gestalt Principles
- Gestalt principles are not low-level feature detection alone: edge-detection, motion-detection, and color-detection are feature-extraction operations that precede gestalt organization; the gestalt operations take features as inputs and group them into wholes — Palmer and Rock (1994) explicitly distinguished entry-level uniform connectedness from later grouping operations and from primitive feature extraction.
This sourceIntroduces uniform connectedness as the entry-level grouping principle operating prior to and in interaction with the classical principles, distinct from feature extraction and downstream semantic processing.

Palmer & Rock supply the entry-level uniform-connectedness claim: UC organizes the field into primitive units before grouping, but not the edge/motion/color feature-extraction distinction.
“We argue that UC cannot be reduced to such grouping principles, because it is not a form of grouping at all. We then propose a theoretical framework within which UC accounts for the initial (or entry level) organization of the visual field into primitive units.”

Mechanisms¶
- Arrows and Connectors
- Arrows exploit the Gestalt principle of uniform connectedness — elements joined by a line are perceived as related before any label is read — which is precisely why a stray connector implies a relationship that isn't there.
This sourceShows that visually connected elements are initially organized as a perceptual unit and therefore appear related.

- Its failure mode traces to uniform connectedness
This sourceDefines uniform connectedness as a strong grouping principle by which a closed connected region is perceived as a single unit.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 3 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
