| Outline of Final Research Achievements |
One of the essential linguistic faculties of humans is the ability to recognize the regularity of sound configurations to extract words from syllable sequences in speech. Whether non-human primates can analyze such auditory regularities or detect boundaries of sound chunks is controversial. Here, to investigate whether monkeys can analyze auditory syntax structures, 2 common marmosets were trained to discriminate auditory patterns. Consequently, the marmosets were not able to process the temporal configuration of sounds regardless of the complexity of the stimulus, whereas they could recognize the acoustic features of the stimulus. The current findings did not coincide with previous findings that suggest an ability to process syntactic rules of sounds in monkeys. The present results may be supported by recent neuroimaging studies: the modest organization of the arcuate fasciculus in non-human primates may not carry sound syntax information.
