Quantifiable measure linking structural properties of configurations to human perception, supporting the mathematical reality of wholeness.

- The key experimental finding: the number of subsymmetries (locally symmetrical connected segments) in a pattern predicts its perceived coherence; most coherent strips have 9 subsymmetries, least coherent have 5; the measure correlates almost perfectly with combined experimental rank order
- Finding that relative coherence rankings remain constant across different people and across different cognitive processing tasks (description, memorization, tachistoscopic recognition), establishing coherence as an objective feature of cognitive processing
- Finding that giving extra points to longer symmetrical segments reduces correlation with experimentally measured coherence, showing large symmetries contribute little extra; what matters more is the number of smaller local symmetries
- Quantitative result showing weaker relationship between accuracy and contra-positive coherence.
- A property that makes a segment of space stand out as a center; determined by symmetry, connectedness, convexity, etc.
- Quantitative result supporting the idea that local symmetry counting approximates perceived life in visual patterns.
- Concurrent work result showing emergent misalignment occurs in small models
