语言中的任意性原则假定语言符号与其所指之间不存在内在联系。然而，越来越多的声音象征主义研究表明，标签的语音属性与其所指对象的知觉属性之间存在一些天然的偏向映射(Maurer，Path man，&Mondloch，2006)。我们提出了新的行为和神经生理学证据，证明了声音-象征主义的心理现实。在一项捕捉自然语言解释过程的分类任务中，当标签-对象映射是声音符号时，参与者识别新对象的速度比不是声音符号时更快。此外，早期负的脑电波形显示出对声音-符号标签-物体关联的敏感性(在物体呈现的200毫秒内)，突出了物体和用来命名它们的标签之间的非任意关系。这种对声音-符号标签-对象关联的敏感性可以反映更一般的听觉-视觉特征整合过程，其中听觉刺激的特性有助于映射到特定的视觉特征。(C)2009爱思唯尔B.V.保留所有权利。
The principle of arbitrariness in language assumes that there is no intrinsic relationship between linguistic signs and their referents. However, a growing body of sound-symbolism research suggests the existence of some naturally-biased mappings between phonological properties of labels and perceptual properties of their referents (Maurer, Pathman, & Mondloch, 2006). We present new behavioural and neurophysiological evidence for the psychological reality of sound-symbolism. In a categorisation task that captures the processes involved in natural language interpretation, participants were faster to identify novel objects when label-object mappings were sound-symbolic than when they were not. Moreover, early negative EEG-waveforms indicated a sensitivity to sound-symbolic label-object associations (within 200 ms of object presentation), highlighting the non-arbitrary relation between the objects and the labels used to name them. This sensitivity to sound-symbolic label-object associations may reflect a more general process of auditory-visual feature integration where properties of auditory stimuli facilitate a mapping to specific visual features.
