The National Psychology Exam rarely tests a label. It tests the single criterion that separates two near-identical categories — permitted from mandatory, screening from diagnostic, one disorder from its comorbid twin. Find the pivot, defend the call.
The 6 Master Discriminators reasoning-engine.json
Every item below anchors to one of these pivots. When two options survive, the pivot question separates them.
Threshold Isolator D033 · AHPRA-style items
Read the vignette. Click the cell where the category sits — then select the ONE criterion that justifies it. A wrong click reveals the single distinguishing feature and surfaces the companion audio as remediation.
Modality Comparison Matrix D006 × content-inventory D3
The intervention-modality table rendered as a cell-reveal grid. Click any cell to reveal it. Filter by dimension, then answer: which modality owns THIS distinguishing technique?
Psychopathology DDx Decision Tree NPE-005 / 008 / 017 · content-inventory
Branch on the gate that discriminates — age, primary symptom cluster, comorbidity rule. Each path lands on a diagnosis with the criterion-based rationale.

10 features. One discriminator each. 12 seconds per feature. Speed forces the pivot to become reflex.
