Capturing frequency components of glided tones: Frequency separation, orientation, and alignment

Abstract

If two sinusoidal glides, Y and Z, synchronous in onset and offset, glide in parallel on a log frequency scale, they fuse and sound like a single rich glide. However, it is possible to capture Y (the target) into a sequential stream by using as a captor a pure tone glide, X, that precedes the YZ glide in a repeating cycle. The cycle then breaks perceptually into two streams, an XY stream and a Z stream. The strength of capturing depends on the similarity of the captor and target glides with respect to both frequency range and orientation. There appears to be no special capturing effect when the captor and target glides are aligned on a common trajectory. © 1981 Psychonomic Society, Inc.
