Abstract:

Several studies of temporal pattern perception were conducted, using tasks where the listener discriminated whether or not two tonal sequences formed the same temporal pattern. Performance was modeled using the Pattern Correlation Model, which assumes that the listener estimates the correlation between the pattern of intervals marked by the tones in each sequence. The model was applied to experiments where the sequences were a compressed or expanded in time b presented at different frequencies and to different ears c onset delayed from 1 to 1500 ms and d subject to cyclic repetitions within each sequence. Other experiments have concerned 1 the discrimination of rhythmicity 2 visual information processing as a function of spatial position and time stress and 3 modeling and computer simulation of systems for group signal detection.
