Abstract
Previous linguistic research has revealed that both people and animals can learn to discriminate sounds through both active training and passive exposure. However, the training regimens that result in optimal learning are still unexplored. Using mice as a behavioral model, we sought to first characterize the sound discrimination learning process for simple sounds. In this study, mice underwent daily sound discrimination training using sounds that differed in either spectral or temporal features. We found that mice are easily able to discriminate between high and low frequencies, but not middle frequencies. Additionally, procedural modifications need to be added to the AM sound discrimination protocol so that they can successfully discriminate between these sound sets. Success in teaching these sounds to mice can result in proceeding with the next steps of utilizing training with different combinations of active training and passive exposure.
