环境声音和语言刺激的神经认知加工共享共同的语义资源，并且可以导致用于产生被动听到的声音或言语的运动程序的激活。我们调查了在何种程度上的环境声音的认知，像语言，依赖于独立的声学输入的符号心理表征。在一个分层排序任务中，我们发现，非生命的声音的评价是一贯偏向于对声学信息的重点。然而，生活的声音的评价自发地集中在独立于声音的语义信息，但可以依赖于声学信息暴露后的上下文组成的非生活的声音。我们将这些结果解释为对非生命声音的强大标志性处理策略和对生命声音的灵活符号处理策略的支持。(C)2010年爱思唯尔公司All rights reserved.
The neurocognitive processing of environmental sounds and linguistic stimuli shares common semantic resources and can lead to the activation of motor programs for the generation of the passively heard sound or speech. We investigated the extent to which the cognition of environmental sounds, like that of language, relies on symbolic mental representations independent of the acoustic input. In a hierarchical sorting task, we found that evaluation of nonliving sounds is consistently biased toward a focus on acoustical information. However, the evaluation of living sounds focuses spontaneously on sound-independent semantic information, but can rely on acoustical information after exposure to a context consisting of nonliving sounds. We interpret these results as support for a robust iconic processing strategy for nonliving sounds and a flexible symbolic processing strategy for living sounds. (C) 2010 Elsevier Inc.
