Biological origins of auditory cognitive ability in small apes and primates

我研究了非人类灵长类动物对听觉刺激的偏好和认知特征，包括长臂猿和其他旧大陆猴子。我使用了需要特殊强化训练和条件反射的实验范式，即听觉感官强化，来测量灵长类动物的听觉偏好。对于听觉感官的强化，身体的运动和方向被辅音、不谐音和生物声音的感官刺激所强化。结果表明，猴子对辅音刺激没有表现出偏好，这与人类的听觉偏好相反。

I investigated the preference and cognitive features for auditory stimuli on non-human primate, including gibbons and the other Old World monkeys. I used the experimental paradigm requiring the special and intensive training and conditioning, which are auditory sensory reinforcement, to measure the auditory preference of primates. For the auditory sensory reinforcement, the body movements and orientation is reinforced by the sensory stimuli of consonant, dissonant, and biological sounds. The results revealed that monkey did not show the preference for the consonant stimuli, contrary to human auditory preference.
