听觉序列

Inspired by the classic Simon electronic memory game (1978), this trains auditory + visual sequencing memory.

Each trial plays an increasing-length sequence of tones with synchronized color flashes.

Repeat the sequence by tapping pads. Make a mistake = trial fails.

Multimodal encoding (sound + color) gives a memory boost over single-channel tasks.

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.

1. Listen + watch the sequence play.
2. Tap the pads in the same order to repeat.
3. Each round adds one item. Two consecutive failures end the session.
4. Headphones recommended for clean tones.
