Dual N-Back: Brain Training App-Analysen für 2. August

Working memory is the mental workspace behind focus, reasoning, and learning. Dual N-Back is a focused trainer built around the n-back protocol from Jaeggi et al. (2008, PNAS) — now with Single, Dual, Triple, and Quad training modes. Track visual positions and audio letters simultaneously. When the current stimulus matches what appeared N steps back, respond. Simple to learn, challenging to master. ADAPTIVE N.DD SYSTEM The N.DD system delivers fine-grained difficulty progression through micro levels like 2.45 or 3.78. Seven parameters adjust together (pace, timing, lures, and more) to keep each session in your optimal challenge zone. SINGLE N-BACK MODES Practice one modality at a time — Position, Audio, Color, or Shape. Easier to learn, useful for warming up or strengthening a weaker channel. TRIPLE AND QUAD N-BACK Add a third or fourth modality (color, shape) alongside position and audio for the harder variants serious practitioners seek. D'-PRIME MEASUREMENT Track performance with the sensitivity index used in cognitive research. Raw accuracy is misleading — 90% could mean excellent play or lucky guessing. D'-prime separates real signal from noise. WORKING MEMORY ASSESSMENT Monthly Counting Span Tests measure your working memory capacity independent of n-back skill. The same validated methodology used in research labs, built right into the app. SESSION REPLAY Step through the full trial sequence of any session to see exactly where errors occurred and review your approach. SESSION NOTES Tag any session with a quick note ("tired today", "first session after coffee") to self-experiment with what affects your sessions. FREE PLAN 10 sessions per day. No credit card required. PRO — $4.99/month or $39.99/year Unlimited sessions, monthly Counting Span assessments, and detailed analytics. SUBSCRIPTION DETAILS Pro subscriptions auto-renew monthly or yearly at the prices above unless cancelled. Cancel anytime from Google Play → Subscriptions.
