The science behind brain training — what actually improves, and how to practice it. No hype, no «+IQ» promises.

• How to train working memory — what the science actually says Working memory is trainable, but transfer is narrower than most apps promise. Learn what improves and how to practice honestly.
• Why active recall and spacing work together Retrieving an answer after a delay creates a stronger learning signal than simply reading it again.
• The Stroop test, explained — and how to practice it Why naming the ink colour is difficult, what Stroop interference measures, and how to interpret practice without inflated claims.
• Attention is a set of networks, not a single spotlight Alerting, orienting, and conflict control contribute differently to fast and accurate performance.
• What creates the cost of switching tasks Changing rules adds preparation, retrieval, and interference costs even when the next task is known.
• Planning is more than reaching the final state Tower tasks reveal how a person forms subgoals, anticipates constraints, and repairs a plan.
• What a processing-speed score actually contains A timed response combines perception, decision, and movement rather than measuring one pure speed.
• Why faster is not always better Speed and accuracy change together because decisions require a chosen amount of evidence.
