Effects of regular and irregular accents on perception of temporal variations in pure tone sequences

Abstract: Research results extending back to the end of the nineteenth century indicate that creating rhythmic groups in a sequence of sounds by the manipulation of one dimension of sound may affect perception of other dimensions. One reliable effect of this kind is that higher intensity sounds are heard as being separated from the preceding sounds by longer intervals of time. I investigated this phenomenon in pure tone sequences in which higher intensity tones were placed either at regular or irregular intervals. A signal detection procedure was used to permit separate analyses of sensitivity and response bias. I will discuss the results as they relate to general theories of perception.
