There are 60 fixed positions in the background layout, but only the illuminated dots are shown on screen.
The lighting cadence stays constant, and each beat swaps one lit dot off while one dark dot turns on.
Press Space only when the visible lit pattern contains exactly one square. Faster reactions earn more points.
Hard mode increases both dot-change speed and target appearance frequency.
六十個點固定排列成 10 x 6 網格,讓任務聚焦在視覺掃描,而不是移動追蹤。
約一半點位保持亮起,每次更新同時熄滅一點並亮起另一點,多數變化不代表訊號。
只有目前亮起點位剛好包含一個 2 x 2 正方形時,受測者才應按下 Space;邏輯會避免同時出現雙正方形狀態。
任務重點是訊號偵測速度、誤按控制,以及重複微變化下的持續視覺掃描能力。
