Non-Verbal Paradigm for Assessing Individuals for Absolute Pitch

Autistic individuals have been observed to demonstrate high intelligence through musical communication, leading to many empirical studies on this topic. Absolute Pitch (AP) has been a captivating phenomenon for researchers, although there has been disagreement regarding AP percentages among the population and appropriate testing methods for AP. This study analyzed data collected from 118 people, using a pitch matching paradigm designed specifically to be inclusive of those who are likely to have note-naming difficulty due to communication challenges. Thirty-eight participants were autistic individuals, 32% of which were considered to have severe language impairment. Twelve other participants had other developmental disorders. All but 1 of the 38 autistics (97%) demonstrated exceptional and instantaneous pitch matching abilities on piano. Ten of the 12 (83%) with other developmental disorders demonstrated this ability, and approximately half (53%) of neurotypicals were able to exhibit this ability. Our numbers indicate that with a more inclusive paradigm for assessing AP, it may be demonstratable in close to 50% of the population, and near 100% in the autistic population. This testing method represents a neurodiversity-friendly and fully inclusive, non-verbal paradigm for demonstrating AP.
