Abstract

Event Abstract Back to Event The role of temporal and frequency structure of tones in forming sensory memory representations Johanna Rimmele1, 2* and E. Sussman1 1 Albert Einstein College of Medicine, United States 2 Institute of Psychology I, University of Leipzig, Germany A regular temporal and tone-frequency structure represented in auditory sensory memory allows for the prediction of incoming auditory stimuli. In a passive auditory oddball paradigm, the Mismatch Negativity (MMN) component of the event-related potential (ERP) to temporal pattern deviants was recorded as a measure of auditory sensory memory representation. In four experimental conditions sounds were presented with: 1) both a regular temporal and a regular frequency pattern; 2) only a regular temporal pattern; 3) only a regular frequency pattern; 4) no regular pattern. We found that in conditions with a regular temporal pattern, MMN amplitudes were enhanced compared to conditions with no temporal regularity. There was a tendency toward a larger MMN amplitude when auditory stimuli were presented with both a regular temporal and a regular frequency pattern. Although tone frequency seemed to hold a structuring role for temporal pattern processing, a regular frequency structure was not required to set up a sensory memory representation of temporal patterns.
