The effects of stimulus uncertainty on auditory perceptual learning

Grant Type: Young Investigator Grant, Second Year
Institute: Department of Communication Sciences and Disorders, University of Haifa

The perception of sound and speech can improve with practice; however learning is often specific to the trained conditions limiting the use of training in clinical and educational settings. Here we propose to test the hypothesis that perceptual learning may generalize more broadly if uncertainty is introduced into the training regimen thus forcing listeners to engage working memory mechanisms. We will train listeners on the discrimination of syllables and tone durations under conditions varying in the degree of stimulus uncertainty and compare the degree of transfer to untrained stimuli and tasks between the different training regimens and to untrained groups.
