Suppressive neural influences lump together several distinct physiological mechanisms
Evidence
Positively and negatively weighted vectors are interpreted as excitatory and suppressive influences, respectively (Rust et al. 2005 ; Schwartz et al. 2006 ; Sneary and Lewis 2007 ). However, mechanical suppression, adaptation, and refractory effects may all contribute to what we term “suppressive” influences. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3847 (

Both younger and older adults in the present study showed significantly more suppression measured with short combined maskers than with longer combined maskers. Several of the older participants, who had no measurable suppression with the longer combined masker, had a small amount of suppression measured with the shorter combined masker. — Dijk, Pim van, Physiology, Psychoacoustics and…, 959 (
