Re: Sensitivity to increments and decrements
Moore and colleagues published several papers on this topic in the 1990s,
mostly in JASA. See also a paper by Glasberg et al. (2001) in Hearing
Research and a paper by Gallun and Hafter (2006) in JASA. Increment
detection is generally better than decrement detection, particularly for

Subject: Sensitivity to increments and decrements
Is there anything known about the existence of differences in the
sensitivity to intensity increments versus to intensity decrements?
Laurent Demany pointed me to a paper by Sinnott et al. (1985) who found
no such difference in humans, while they found an advantage for
increments in monkeys:

Is this finding (as to the symmetry of human increment / decrement
