中文摘要：

作为生物体适应环境的特征,偏侧性在人类和动物中普遍存在。偏侧性能提升个体处理环境信息的效率并更快对环境刺激做出响应,从而提升个体对环境的适合度。听觉作为重要的感知方式也具有偏侧性,并且在多个类群中具有相似趋势。本文总结了听觉偏侧性在不同动物类群间的相似性和特异性,对听觉偏侧性的产生机制进行了归纳,并探讨了群体水平听觉偏侧性的成因。最后对研究的不足之处提出了可能的解决方案,并对听觉偏侧性研究方向进行了展望。

英文摘要：

Lateralization is a common characteristic among the vertebrates including humans and is proposed to improve animals＇ fitness through processing environmental information efficiently and responding to events more rapidly. As one of the major perceptual functions,asymmetric auditory perception has been found in various species with similar tendency： the right-ear / left-hemisphere dominates conspecific sound perception while the left-ear / right-hemisphere preferentially processes interspecific and novel sounds. Previous studies concerning auditory lateralization in different animal species were reviewed and the similarity and specificity across species were compared. The possible mechanisms underlying auditory lateralization in individual level and the possible cause of auditory lateralization in population level were summarized. Finally,some protocols for studies on lateralization and the possible prospects in the future were proposed.
