Abstract

Objective

the present study aimed to investigate the applicability and feasibility of a new paradigm for assessing sound lateralization behavior.

Design

The Click Ordering Lateralization Test comprises two tracks (tracks 1 and 2), with 54 trials each. Each trial consists of one of nine intervals ranging from 0 to 230 ms between two noise bursts, whereby subjects must indicate on which side they first heard the noise. The COLT procedure was applied to 30 normal-hearing children (between 8 and 14 years old).

Results

the results indicated that an interaural time difference (ITD) of 0 ms functions as a control item, and after an ITD of 170 ms, the lateralization threshold reaches a ceiling effect. Different analysis methods were investigated in this study, with the total percentage score and a lateralization threshold of 5 hits deemed the most reliable methods. No differences were observed between test tracks and performance across the tracks was shown to be reliable and equivalent.

Conclusions

there are few procedures available to assess sound laterization in a clinical setting. This study presents the COLT as an easy-to-apply, reliable test for use in children aged between 8 and 14 years old.

点击排序偏侧化测试：评估声音偏侧化行为的新范式的适用性和可行性

目的探讨一种评价声音偏侧行为的新范式的适用性和可行性。DesignThe Click Ordering lateral Test包括两个轨道（轨道1和轨道2），每个轨道54次试验。每次试验包括两次噪音爆发之间从0到230毫秒的九个间隔中的一个，在此期间，受试者必须指出他们首先听到噪音的哪一边。对30名听力正常的儿童（8 ~ 14岁）进行COLT检查。结果：耳际时差（ITD）为控制项，而当耳际时差（ITD）为170 ms时，侧边化阈值达到天花板效应。本研究研究了不同的分析方法，总百分比得分和侧化阈值为5次命中被认为是最可靠的方法。在测试轨道之间没有观察到差异，并且跨轨道的性能显示是可靠和等效的。结论在临床环境中，很少有可用于评估声音偏侧的方法。本研究提出COLT是一种易于应用，可靠的测试，适用于8至14岁的儿童。

期刊介绍： The purpose of the International Journal of Pediatric Otorhinolaryngology is to concentrate and disseminate information concerning prevention, cure and care of otorhinolaryngological disorders in infants and children due to developmental, degenerative, infectious, neoplastic, traumatic, social, psychiatric and economic causes. The Journal provides a medium for clinical and basic contributions in all of the areas of pediatric otorhinolaryngology. This includes medical and surgical otology, bronchoesophagology, laryngology, rhinology, diseases of the head and neck, and disorders of communication, including voice, speech and language disorders.
