处理速度

神经处理和算术流畅度的原始速度。

每个练习针对一个狭窄的构念：工作记忆、选择性注意、速度。

训练模式提供即时反馈。测试模式有计时和评分。

Each exercise here is scored so you see your real progress, not vague points. Train mode gives immediate feedback. Test mode is timed and comparable to your past sessions.

Each test is constructed using Item Response Theory (IRT) and Classical Test Theory (CTT) to ensure reliable measurement of knowledge and ability across different difficulty levels.

Questions undergo rigorous review including difficulty calibration, discrimination analysis, and distractor effectiveness evaluation to maintain high assessment quality.

The neural basis is white-matter integrity: faster axonal conduction, especially in long-range fronto-parietal tracts, predicts faster responses. Cardiovascular fitness measurably preserves this.

1. Do RT at the same time each day: Alertness varies. Same time → comparable numbers.
2. Drill mental math in short bursts: Three 3-minute sprints beat one 10-minute session for arithmetic fluency.
3. Move before measuring: Light physical activation (walk, stretch) consistently shaves 20–40ms off RT.
4. Log everything: You can't improve what you don't measure. Keep your sessions and watch the trend.
