音频 N-Back

Audio N-Back replaces visual positions with auditory tones. The phonological loop alone is challenged.

Headphones recommended. Each step plays a tone from a 8-note scale.

Performance is independent of visual N-back — many people are stronger in one modality than the other.

Together with Dual N-Back, this forms the canonical Jaeggi training set.

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. Put on headphones for clean audio.
2. A tone plays. Press Match if it equals the tone played N steps back.
3. Don't look at the screen — close your eyes if it helps.
4. Audio working memory is a separate skill — expect a learning curve.
