PPT – Psychological Performance Tuning
summary
Shows concrete tactics: use skeleton screens and above‑the‑fold loading to hit a fast first meaningful paint, preload with preemptive start or divide work into meaningful chunks so long tasks feel like many short ones. Cites Weber’s just‑noticeable‑difference (15 minutes on Eurostar goes unnoticed), page growth (14 KB → ~2.5–4 MB) and Nielsen timing bands (100–200 ms, 500 ms–1 s, 2–5 s, 5–10 s). Recommends optimistic UI, early completion (streaming buffer), and progress‑indicator types A–D; MIT study shows passive waits feel ~36% longer.
