Dear Chris, 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 short durations.

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: Sinnott, J. M., Petersen M. R., Hopp, S. L. (1985). Frequency and intensity discrimination in humans and monkeys. Journal of the Acoustical Society of America, 78, 1977-1985. Is this finding (as to the symmetry of human increment / decrement sensitivity) unchallenged?
