Marker combination effects were found in the discrimination of auditory durations using short target parts of tones marked by rising and/or falling level changes. The obtained JNDs were the smallest for durations marked by two rising changes (rise-rise type) or for those of the rise-fall type; moderate for those of the fall-rise type; and the largest for those of the fall-fall type.
Although the variations in the experimental conditions were limited, they certainly provided direct evidence for (1) the predominance of rising markers to falling markers, and for (2) the predominance of rise-tofall durations to the reverse case, fall-to-rise durations, in the discrimination of auditory durations.
