Hi Farrell: Audio is good. I believe all senses can "come alive" if required to do so" by the lesson goal or activity the teacher has chosen. I think all the senses can be trained to "tune in", or become sensitive to the tenets of learning, and that can enhance the learning process. By forcing the student to use their imagination, they can invision many senses they typically take for granted. With practice, these senses can be hightened and applied to study, with improved learning outcomes as a result. Regards, Barry
