Perceptual Adaptation of Lexical Tones Is Degraded but Can Be Improved With Lengthened Stimulus Duration in Musically Tone-Deaf Individuals

Both amusics and controls could perceive syllables and tones in an integral manner. However, amusics were degraded in perceptual adaptation of tones, and they could benefit from lengthened stimulus duration for the improvement of their performance. Overall, this study deepened our understanding of amusia and provided a possible strategy for intervention programs to adopt longer auditory items to remediate amusia.
