Abstract: Five experiments were carried out in an investigation of auditory local-global processing. Each experiment employed two separate sets of stimuli (T. Justus and A. List, 2005): one set varying over the dimension of frequency ( High-Low Stimuli) and one set varying over the dimension of time (Fast-Slow Stimuli). Frequency and temporal ranges were chosen for their role as indispensable auditory attributes. The stimuli were designed to parallel certain features present in visual hierarchical stimuli: independent levels and target patterns orthogonal to the levels. The High-Low Stimuli were adopted based on the hypothesis that the brain processes auditory frequency information and visual spatial frequency information analogously, whereas the auditory Fast-Slow Stimuli imitate the hierarchical structure present in the visual local-global stimuli. The current experiments tested whether the auditory and visual modalities share attentional resources for local-global processing, whether auditory levels are absolute or relative in nature, whether monaural presentation reveals hemispheric asymmetries in processing and whether local or global precedence was present for our stimuli. Results indicated that audition and vision do share attentional resources under certain conditions, that temporal hierarchical processing is based on relative selection of ranges, that processing frequency information leaves lateralized traces influencing later frequency processing and that, under current conditions, an auditory local precedence hypothesis was supported.
