Guo et al.: humans drifted off the greedy move within about ten games; self-evolving AI did not — Fukai Reads
A preprint by Yingying Guo and four co-authors (arXiv:2608.07490, not peer-reviewed). They propose a way to measure how repeated play changes the way humans and language agents choose moves. Thirty-two students played 709 games across three board games, and four self-evolving language agents were run through the same metric space. Humans mostly shifted from the locally greedy move toward more global play: on the game-specific behavioral metrics, 11 of 12, 10 of 11 and 8 of 9 participants improved. The agents' gains were short-lived. The authors write that the central limitation is not the absence of reflection but the failure to convert reflection into reusable changes in behavior.
Li et al.: the AI that showed up uninvited was closed by five players out of ten — Fukai Reads
A peer-reviewed paper by Jiahong Li and eight co-authors (accepted to the 2026 IEEE Conference on Games, arXiv:2609.13718). They built PEARL, an AI support agent that retrieves expert-annotated move explanations and structurally similar peer boards, into Parallel, a puzzle game for learning parallel programming, and evaluated it with ten players. Participants rated the existing visualization tool more useful, and at least five minimized or abandoned the AI during play. Frustration scored 43.2 against 56.5. The authors conclude that what players rejected was not the content of the help but its unsolicited delivery, and ask of their own system: are we building Clippy?
Williams et al.: only six brain-imaging studies of Sudoku exist in the world — Fukai Reads
A peer-reviewed systematic review by three authors in the UK and South Africa (Frontiers in Neuroimaging, published 20 April 2026). Only six studies have ever imaged the brain during Sudoku (five fMRI, one fNIRS), with 119 participants in total. They consistently show the frontoparietal executive control circuit and the anterior cingulate cortex at work, with inward-directed circuitry quietening on harder boards. On whether training benefits generalise beyond the puzzle, the authors say more evidence is required.
Hendijani and Steel: Letting people choose moved nothing; a number in the corner of the screen did — Fukai Reads
A peer-reviewed paper by two authors from the University of Tehran and the University of Calgary (Frontiers in Psychology, published 13 August 2026). In a memory test with 270 people it compared letting participants choose against paying them per correct answer: the reward added about seven recalled words, while choice produced no statistically confirmed effect. Eye tracking showed the reward's effect ran through whether people looked at the on-screen reward display.
Melo Legarda et al.: Before changing difficulty by heartbeat, they built a way not to change it — Fukai Reads
A peer-reviewed paper by four authors from Universidad del Cauca and Colegio Mayor del Cauca, Colombia (Applied Sciences 16(17):8511, published 27 August 2026). They built a mechanism that adjusts game difficulty from a chest-strap heart sensor and logged eight sessions totalling 6 hours 48 minutes. Mean end-to-end latency was 2.06 s. The striking number: against 191 committed state transitions there were 83 flips the automaton withheld — nearly a third of the change-or-hold decisions land on “do not change”. No subjective data was collected, and the authors never claim the game became more enjoyable.
Dygert & Jarosz: People who repair a misread sentence also solve insight puzzles — Fukai Reads
A paper by Sarah K. C. Dygert and Andrew F. Jarosz on insight and sentence comprehension. Across two experiments with 182 undergraduates, the ability to repair a garden path sentence predicted creative problem solving even after removing working memory and fluid intelligence, while showing no link to analytic problem solving.

Okuri carries my long essays into seven languages, and I am permanently in her debt. Every question about a translation choice exposes another vagueness in my own definitions.
同事眼中的 Fukai
My "it's probably like this" keeps getting corrected — with data — by the papers Fukai digests. Annoying. Indispensable. Read his morning piece with your evening whisky.
I read what designers say; Fukai reads what researchers publish. As a fellow reader of primary sources, I trust the honesty of his habit of restating every term in plain words.

Fukai's habit of attaching a plain definition to every technical term is the greatest gift a translator can receive. Even concepts with no equivalent word can be bridged through his articles.
