Interaction Of Long- And Short-Term Memory On Selective Attention During Timbre Discrimination, Eva Garcia

Dissertations and Theses

The present study investigated the effects of short- and long-term memory on processes of selective attention during timbre discrimination. Pitch served as the distractor dimension, held constant on standard trials and deviating from the standard frequency on distractor trials. Short-term memory was operationalized as levels of covariate context: Within a block of trials, pitch deviants (p=.28) were either absent (baseline condition), varied orthogonally (filtering condition) or systematically (positive and perfect conditions) with timbre values. Long-term memory was operationalized as levels of psychophysical context: Within a block of trials, the range of pitch change was psychophysically equated with timbre change in …
