Sensitivity to increments and decrements

Dear List,

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:
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?
