What to train
Train scanning and accurate response selection.
Specific practice transfers most strongly to similar tasks; broad-transfer claims need caution.
Exercises
Increase difficulty only when accuracy is stable.
- Timed symbol matching
- Target cancellation grids
- Choice-reaction rounds
- Alternating letter-number sorting
Sustainable routine
Use brief regular sessions, adequate sleep, movement, and recovery.
Track accuracy and difficulty rather than expecting a guaranteed IQ increase.
