Science

Pomodoro technique — what the studies actually show. The evidence list below names the studies that actually constrain timed focus boxes.

Scores here are relative ranks inside this atlas, not lab grades or official cut scores.

Evidence

• Classical source — Cirillo is the public name this atlas attaches to the origin story of attention residue.
• Modern constraint — Leroy and later work keep attention residue from being treated as magic: effort and test still matter.
• Exam listing — attention residue earns its exam-fit score when the sitting asks for a name, number or chosen method under time.
• Dunlosky utility — Dunlosky's reviews treat practice testing and distributed practice as high-utility — attention residue is one way to run them.
• Bjork difficulty — Bjork's desirable difficulty says a slightly harder retrieve of attention residue beats a fluent reread.

Mechanisms

• Retrieval as encoding — Producing attention residue from a blank page is a new encoding, not a photocopy of the reread.
• Error as signal — A miss on attention residue tells you which fact to split or rewrite. A fluent reread hides that.
• Time-box honesty — attention residue that only happens after midnight is a scheduling fail, not a character fail.
• Transfer test — If you cannot do attention residue in a different room, you have context, not skill.

Researchers

• Cirillo — Cirillo is cited as a public scientific name for attention residue, not as a private coach.
• Leroy — Leroy appears because later measurement tightened the first story of attention residue.
• John Dunlosky — Dunlosky's utility rankings are the classroom constraint: attention residue should earn its hours against cheaper rereading.
• Robert Bjork — Desirable difficulty explains why attention residue that feels slightly late is often the useful one.

Educational atlas — not an official syllabus, medical advice, or leaked item bank. Pomodoro technique: Keep the public outline in view and treat this page as method, not a leaked key.
