title: Split-interval illusion: size of effect with pulse-bounded durations.
abstract: The magnitude of the split-interval illusion was measured by method of constant stimuli, with variable intervals between 700 and 1300 msec. and a 1000-msec. standard. All intervals were bounded by 20-msec.-1-kHz pulses and contained a single 20-msec.-2-kHz pulse which either split the interval in a 25:75 ratio or a 75:25 ratio. Intervals split early were overestimated relative to equivalent intervals split late by an average of 8.4% of the 1000-msec. standard.
