What the evidence says
B
Sustained attention & executive function
Moderate evidence · Good evidence, with some gaps or inconsistency.
- Effect size
- g = 0.257–0.643 vs. waitlist/no-treatment; g = 0.192–0.394 vs. active controls — small-to-moderate but consistent across cognitive subdomains.
- Evidence base
- 111 RCTs, n = 9,538 in the largest recent meta-analysis — one of the best-powered evidence bases in this entire database.
- Population
- Effects are consistent across age groups including healthy older adults; results hold regardless of intervention length or delivery format in moderator analyses.
- Dosage / protocol
- Typical studied programs run 8 weeks (e.g. MBSR-style), 20–45 min/day; shorter single-session inductions show smaller but still positive acute effects.
- Contraindications & cautions
- Generally safe; rare reports of increased anxiety or dissociative experiences in people with a trauma history during intensive practice — introduce gradually.

Mechanism
How it works
How Meditation Trains the Brain's Attention Networks
Focused-attention meditation repeatedly trains the brain's alerting, orienting, and executive attention networks by having the practitioner notice mind-wandering and redirect attention back to an anchor (usually the breath) — functioning as repetition-based training for sustained focus, similar to how repeated reps train a muscle.
