Temporal Aspects of Stimulus-Driven Attending in Dynamic Arrays
通过三个实验研究节奏如何影响听觉序列中音高比较的准确性,发现听众对节奏预期的音调判断最准确,对意外音调判断最差,且该效应随时间持续,但无节奏或节奏不规则时消失。
Auditory sequences of tones were used to examine a form of stimulus-driven attending that involves temporal expectancies and is influenced by stimulus rhythm. Three experiments examined the influence of sequence timing on comparative pitch judgments of two tones (standard, comparison) separated by interpolated pitches. In two of the experiments, interpolated tones were regularly timed, with onset times of comparison tones varied relative to this rhythm. Listeners were most accurate judging the pitch of rhythmically expected tones and least accurate with very unexpected ones. This effect persisted over time, but disappeared when the rhythm of interpolated tones was either missing or irregular.
