Abstract
Purpose: Neurotypical individuals show a robust "global precedence effect (GPE)" when processing hierarchically structured visual information. However, the auditory domain remains understudied. The current research serves to fill the knowledge gap on auditory global-local processing across the broader autism phenotype under the tonal language background.
Method: This study examined auditory global-local processing styles in 37 Mandarin-speaking young adults (age: M = 20.35, SD = 2.32; 19 males) with varying autistic traits. The participants were required to judge global and local pitch structures in nine-tone melodies with both congruent and incongruent conditions under both directed attention and divided attention modes.
Results: We found that GPE persisted independent of the attention modes during hierarchical processing. Autistic traits were among the potential contributors that reshaped GPE in auditory global-local processing under a tonal language background.
Conclusions: Our study provides an initial investigation into auditory global-local processing among Mandarin-speaking individuals across a range of autistic traits, revealing the presence of the GPE effect during hierarchical pitch structure processing. The advantage of global processing versus local processing expanded with increasing autistic traits, providing further support for the notion that auditory global processing may remain intact in autism and the broader phenotype. We highlight that GPE is a process of coarse-to-fine integration of sensory perception and cognitive feedback iteration, which both top-down and bottom-up processes wield influence on. These findings have implications for the study of atypical auditory processing in autism and may help to refine the early diagnosis and auditory-based intervention for autism.
期刊介绍：
Mission: JSLHR publishes peer-reviewed research and other scholarly articles on the normal and disordered processes in speech, language, hearing, and related areas such as cognition, oral-motor function, and swallowing. The journal is an international outlet for both basic research on communication processes and clinical research pertaining to screening, diagnosis, and management of communication disorders as well as the etiologies and characteristics of these disorders. JSLHR seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work.
Scope: The broad field of communication sciences and disorders, including speech production and perception; anatomy and physiology of speech and voice; genetics, biomechanics, and other basic sciences pertaining to human communication; mastication and swallowing; speech disorders; voice disorders; development of speech, language, or hearing in children; normal language processes; language disorders; disorders of hearing and balance; psychoacoustics; and anatomy and physiology of hearing.
