大脑半球之间功能的不对称分布已在听觉模式中得到广泛研究。目前的方法大量借鉴了视觉局部-全局研究，试图确定局部-全局听觉处理是否像视觉一样是偏侧化的。在视觉中，横向局部-全局处理可能依赖于空间频率信息。通过视觉空间频率和听觉维度之间的类比，开发了两组听觉刺激。在高-低刺激集中，我们操纵频率信息，在快-慢刺激集中，我们操纵时间信息。快慢刺激还模拟视觉分层刺激结构，其中局部模式的排列决定全局模式。与以前的听觉刺激不同，当前的刺激集包含视觉局部-全局分层刺激的实验灵活性，允许独立操纵结构水平。先前关于频率和时间范围启动的发现被重复。此外，通过单耳呈现刺激，我们发现频率范围（但不是时间范围）的启动因耳朵而异，这支持了半球不对称地保留先前频率处理痕迹的论点。这些结果有助于揭示大脑处理频率信息的不对称性的大量文献，并将这些结果扩展到启动领域。
Asymmetric distribution of function between the cerebral hemispheres has been widely investigated in the auditory modality. The current approach borrows heavily from visual local–global research in an attempt to determine whether, as in vision, local–global auditory processing is lateralised. In vision, lateralised local–global processing likely relies on spatial frequency information. Drawing analogies between visual spatial frequency and auditory dimensions, two sets of auditory stimuli were developed. In thehigh–low stimulusset we manipulate frequency information, and in thefast–slow stimulusset we manipulate temporal information. Thefast–slow stimuliadditionally mimic visual hierarchical stimulus structure, in which the arrangement of local patterns determines the global pattern. Unlike previous auditory stimuli, the current stimulus sets contain the experimental flexibility of visual local–global hierarchical stimuli allowing independent manipulation of structural levels. Previous findings of frequency and temporal range priming were replicated. Additionally, by presenting stimuli monaurally, we found that priming of frequency ranges (but not temporal ranges) was found to vary by ear, supporting the contention that the hemispheres asymmetrically retain traces of prior frequency processing. These results contribute to the extensive literature revealing cerebral asymmetries for the processing of frequency information, and extend those results to the realm of priming.
