(1), (2) and (3) concerns subjective duration [(1) and (2) use sounds longer/much longer than 200-ms whereas (3) uses sounds of duration < 200-ms]. (4) concerns loudness. 1) Grassi, M., Darwin, C. J.

Differenza nella durata percettiva di suoni crescenti o calanti in intensità: permanenza o decurtamento? Giornale Italiano di Psicologia, 30, 659-663.
