Significance If learning contributes to the development of vocal production in the squirrel monkey, then this will represent an important parallel between primate vocal development and human phonological development and may provide the first nonhuman primate model for studying language development in human children. Objectives The primary objective of this research is to determine the importance of learning in the acquisition of vocal skills in non-human primates. The specific aims are to document the development of vocal production of chuck calls in squirrel monkeys. The chuck call in squirrel monkeys is acoustically different in infants and adults, and is produced primarily by adult females during close affiliative interactions, which shows a strong degree of individuality in acoustic structure. Such characteristics suggest that learning may play an important role in the maturation of this vocal subsystem. Results Data analysis is currently in progress. Over 150 hours of vocal recordings and 400 hours of focal behavioral data have been collected. Results suggest that infant/juvenile squirrel monkeys show social preferences for particular unrelated adult females. Social preference was measured by the amount of time infants/juveniles spent in proximity, contact, and social huddling with different adult females, as well as in the amount and direction of activities such as approaches, social exploration and play, retrievals, and agonistic interactions. These data suggest that sufficient variation exist between infants in their social preferences to evaluate social influences on chuck call development. Over 3000 chuck calls already have been digitized for quantitative acoustic analysis. Preliminary comparison suggests that some acoustic features of chuck calls are learned by infants from unrelated close social associates. Future Directions A combination of advanced bioacoustic techniques and DNA fingerprinting methods will be used to determine the acoustic parameters that are learned from those that are more innately predisposed in squirrel monkey vocalizations.

意义 如果学习有助于声乐的发展 松鼠猴的生产，那么这将代表 灵长类动物声音发育与人类声音发育之间的重要相似之处 语音发育并可能提供第一个非人类灵长类动物 研究人类儿童语言发展的模型。 目标 本研究的主要目的是确定重要性 非人类灵长类动物获得发声技能的学习。 具体目标是记录声乐制作的发展 查克在松鼠猴中叫唤。 查克叫松鼠 猴子的婴儿和成人在听觉上是不同的，并且 主要由成年女性在亲密亲缘关系期间产生 相互作用，在声学方面表现出很强的个性 结构。 这些特征表明学习可能发挥 在这个发声子系统的成熟过程中发挥着重要作用。 结果 目前正在进行数据分析。 超过150小时的声乐 已经收集了录音和 400 小时的焦点行为数据。 结果表明，婴儿/少年松鼠猴表现出社交能力 对特定的、不相关的成年女性的偏好。 社会偏好 通过婴儿/青少年在其中度过的时间来衡量 与不同成年女性的接近、接触和社交聚会， 以及活动的数量和方向，例如 方法、社会探索和游戏、检索和竞争 互动。 这些数据表明存在足够的变异 婴儿之间的社会偏好来评估社会 对卡盘呼叫发展的影响。 已经接到超过3000个chuck电话 已被数字化以进行定量声学分析。 初步的 比较表明，卡盘叫声的一些声学特征是 婴儿从无关的亲密社会伙伴那里学到的。 未来 先进生物声学技术与 DNA 的结合 指纹识别方法将用于确定声学 从那些更先天的参数中学习的参数 松鼠猴容易发声。 关键词 声乐 学习、语言发展、语言进化、生物声学 分析资助 NIH NRSA 奖学金 1-F32-HD07946
