  text: 'Two notes separated by a doubling in frequency sound similar to humans. This
    “octave equivalence” is critical to perception and production of music and speech
    and occurs early in human development. Because it also occurs cross-culturally,
    a biological basis of octave equivalence has been hypothesized. Members of our
    team previousy suggested four human traits are at the root of this phenomenon:
    (1) vocal learning, (2) clear octave information in vocal harmonics, (3) differing
    vocal ranges, and (4) vocalizing together. Using cross-species studies, we can
    test how relevant these respective traits are, while controlling for enculturation
    effects and addressing questions of phylogeny. Common marmosets possess forms
    of three of the four traits, lacking differing vocal ranges. We tested 11 common
    marmosets by adapting an established head-turning paradigm, creating a parallel
    test to an important infant study. Unlike human infants, marmosets responded similarly
    to tones shifted by an octave or other intervals. Because previous studies with
    the same head-turning paradigm produced differential results to discernable acoustic
    stimuli in common marmosets, our results suggest that marmosets do not perceive
    octave equivalence. Our work suggests differing vocal ranges between adults and
    children and men and women and the way they are used in singing together may be
    critical to the development of octave equivalence.'
