Abstract : Several studies of temporal pattern perception were conducted using tasks where the listener discriminated whether two tonal sequences formed the same temporal pattern or which of two patterns was more rhythmic. In different conditions, the stimulus patterns were delayed, time expanded or compressed, presented at different frequencies and to different ears, or constructed of sub- patterns having different temporal correlations. Mathematical models of performance were employed to describe performance in these tasks. Further work was accomplished extending signal detection theory to the performance of statistically ideal and (certain) non-ideal groups. Other experiments were conducted on the processing of visual display elements as a function of element reliability and perceptual structure.
