Developing Mind

All four areas came out below your own midpoint in this run — which says far more about today than about you. Cognitive performance is trainable and famously sensitive to sleep, stress, unfamiliar formats, and plain bad days; a first pass under time pressure is the hardest possible setting. What this result actually gives you is a map: four named areas, each of which responds to practice — puzzles for logic, sketching and navigation for spatial sense, mental arithmetic for numbers, reading and writing for language. People who retake after regular practice routinely move their profile. Treat this as a starting photograph, not a verdict: the interesting number is not today's, it's the one after six weeks of reps.
