| 8 | ## Recency (2026) |
| 9 | |
| 10 | Foundational cards (Dehaene 2011, Price 2012, Perani 2015) remain **valid architecture**. For **von Neumann age bands, intervention, bilingual development** — cite **2020–2026** layer first (Feng, Perdue, Yeh, Grimaldi). Hartshorne boundary includes **2022 statistical debate** — not a single settled cutoff. |

| 14 | ## Scope |
| 15 | |
| 16 | **Brain-level** models of spoken language, reading, and bilingual control. Feeds **design rationale** into pedagogy via bridge matrix — not operational gates. |

| 20 | ## Core constructs (v1) |
| 21 | |
| 22 | | Construct | Summary | Flagship card | |
| 23 | |-----------|---------|---------------| |
| 24 | | **VWFA / letterbox** | Emerges at **literacy onset** (Feng 2022); recycles pre-connected language hub | Feng 2022 · Dehaene foundational | |
| 25 | | **Grapheme–phoneme circuit** | Intervention normalizes reading network (Perdue 2022); GPC training in reviewed studies | Perdue 2022 · Dehaene | |
| 26 | | **Neural dual-route reading** | Sublexical vs lexical vs semantic pathways dissociable | Price 2012 | |
| 27 | | **Bilingual brain (development)** | Network adaptation from infancy; EF advantage **debated** | Yeh 2026 | |
| 28 | | **Bilingual processing (adult)** | Shared L1/L2 network + executive recruitment for L2 | Grimaldi 2020 · Perani 2015 | |
| 29 | | **Sensitive period (grammar)** | Population curve **contested** (Hartshorne vs van der Slik 2022); school oracle = Genesee | Hartshorne boundary | |

| 33 | ## Anti-patterns (neuromyth deny list) |
| 34 | |
| 35 | | Myth | Reality | |
| 36 | |------|---------| |
| 37 | | «Language only in left hemisphere» | Distributed network; reading recruits visual + phonological + semantic systems | |
| 38 | | «Critical period ends at 7» | School L2 (Genesee) + Hartshorne boundary — **different constructs**; see boundary card | |
| 39 | | «Bilingualism confuses the brain» | Control network adapts; school bilingual evidence ≠ harm (see pedagogy SNL) | |
| 40 | | «fMRI proves method X» | Neuro **converges** with behavioral phonics (Dehaene); gates stay behavioral | |
| 41 | | «Reading is purely visual whole-word» | VWFA requires **print–speech mapping** training; visual exposure alone insufficient | |

| 49 | cognition.language-acquisition → input/recast mechanisms |
| 50 | pedagogy.* → gates, probes, program arc |
