Cada ejercicio apunta a un constructo estrecho: memoria de trabajo, atención selectiva, velocidad.
El modo Entrenar da retroalimentación inmediata. El modo Prueba es cronometrado y puntuado.
Each exercise here is scored so you see your real progress, not vague points. Train mode gives immediate feedback. Test mode is timed and comparable to your past sessions.
Each test is constructed using Item Response Theory (IRT) and Classical Test Theory (CTT) to ensure reliable measurement of knowledge and ability across different difficulty levels.
Questions undergo rigorous review including difficulty calibration, discrimination analysis, and distractor effectiveness evaluation to maintain high assessment quality.
Mnemonic training (chunking, method of loci) produces dramatic gains. Ericsson's famous case of S.F. reached 80+ digit span with systematic mnemonic practice. Ordinary practice produces smaller but reliable gains.
An expanded span means richer mental arithmetic, better conversation threads, easier phone numbers.
Paired-associates training trains the hippocampal binding that underlies episodic memory.
Spatial span maps cleanly onto real-world navigation and architectural thinking.
Persistent unexplained drops in digit span warrant medical attention — the task is a sensitive early marker.
Forward: 7±2 in adults. Backward is typically 1–2 shorter. Spans above 9 forward or 7 backward are exceptional.
Older adults show the largest relative gains from paired-associates training, likely because they have more room to improve binding.
Yes — but you'll outgrow these tasks fast. Competition-level mnemonists use journey method and PAO systems. Start here, then move on.
Working memory capacity tracks rested-state alertness. A tired-span measurement is real data, just not your true baseline.
