Abstract

Many animal species can detect dependencies between adjacent visual or auditory items in a string. Compared with adjacent dependencies, detecting nonadjacent dependencies, as present in linguistic constructions, is more challenging as this requires detecting a relation between items irrespective of the number and nature of the intervening items. There is limited evidence that nonhuman animals can detect such dependencies. An animal group in which such abilities might be expected is songbirds, which have learned songs consisting of a series of vocal elements given in specific sequences. So far no songbird (or other bird species) has been tested for its ability to detect nonadjacent dependencies. We examined whether zebra finches can detect the dependencies between items at the edges of artificially arranged strings of song elements. Zebra finches were trained to discriminate 2 sets of dependent song elements that always appeared in the same order (A and B; C and D), from other element combinations (AD, AC, BD, CB, CA, DB). The element combinations were separated by intervening (I) elements. Subsequent tests revealed that the finches could generalize the learned dependencies over different numbers and types of intervening items. Our findings show that the ability for detecting nonadjacent dependencies is not limited to humans or primates, and lend support to theories that suggest that nonadjacent dependencies can be learned by a nonlinguistic associative learning process.

弥合差距:鸣禽对声学非相邻依赖关系的学习。
许多动物物种可以检测到一串中相邻的视觉或听觉项目之间的依赖关系。与相邻依赖关系相比,检测语言结构中存在的非相邻依赖关系更具挑战性,因为这需要检测条目之间的关系,而不考虑中间条目的数量和性质。有有限的证据表明,非人类动物可以检测到这种依赖关系。鸣禽可能具有这种能力,它们学会了由一系列特定顺序的发声元素组成的歌曲。到目前为止,还没有鸣禽(或其他鸟类)被测试过它们检测非相邻依赖关系的能力。我们研究了斑胸草雀是否能够检测到人工排列的歌曲元素串边缘的项目之间的依赖关系。训练斑胸草雀区分两组总是以相同顺序出现的相关鸣声元素(A和B;C和D),从其他元素组合(AD, AC, BD, CB, CA, DB)。元素组合通过介入(I)元素进行分离。随后的测试表明,雀类可以将习得的依赖关系概括为不同数量和类型的干预项目。我们的研究结果表明,检测非相邻依赖关系的能力并不局限于人类或灵长类动物,并为非相邻依赖关系可以通过非语言联想学习过程学习的理论提供了支持。(PsycINFO数据库记录
