Abstract

Introduction: Dichotic listening (DL) is a test where auditory stimuli are presented simultaneously to each ear. DL has clinical applications in assessing APD, schizophrenia, and brain injury. It is sensitive to hemisphere differences and has been used to study language lateralization. The study aimed to develop, validate, and establish norms for a Quadri condition Dichotic Double Word Test (free recall, forced right, forced left, and switch attention) in the Kannada language (DDWT-K).

Methods: This study was carried out in two phases. Phase 1 aimed to develop and validate the DDWT-K and phase 2 involved data collection. The developed novel dichotic test was administered on 100 normal-hearing adults in four conditions - free recall, forced right, forced left, and switch attention.

Results: The results showed significant ear differences in free recall condition indicating right ear advantage. The switch attention condition showed slightly poorer performance when compared to both the forced attention condition indicating greater task difficulty. The test-retest reliability was above 0.7 for all the conditions indicating good reliability.

Conclusions: The findings demonstrated the best preservation of the original dichotic effects and hence ready for clinical use.

开发和验证卡纳达语 Quadri 条件二分法双词测试 (DDWT-K)。

简介二分听（DL）是一种将听觉刺激同时呈现在两只耳朵上的测试。DL 临床应用于评估 APD、精神分裂症和脑损伤。它对半球差异很敏感，已被用于研究语言的侧化。本研究旨在开发、验证和建立卡纳达语四重条件二分法双词测试（自由回忆、强迫右侧、强迫左侧和转换注意）的标准：本研究分两个阶段进行。第一阶段旨在开发和验证卡纳达语二分法双词测试（DDWT-K），第二阶段涉及数据收集。研究人员对 100 名听力正常的成年人进行了新开发的二分法测试，测试分为四种情况--自由回忆、强迫向右、强迫向左、&；注意力转换：结果：结果显示，在自由回忆条件下，双耳差异明显，表明右耳具有优势。与强迫注意条件相比，转换注意条件下的成绩稍差，表明任务难度更大。所有条件的重测信度均高于 0.7，表明信度良好：研究结果表明，原始的二分效应得到了最好的保留，因此可用于临床。

期刊介绍： ''Audiology and Neurotology'' provides a forum for the publication of the most-advanced and rigorous scientific research related to the basic science and clinical aspects of the auditory and vestibular system and diseases of the ear. This journal seeks submission of cutting edge research opening up new and innovative fields of study that may improve our understanding and treatment of patients with disorders of the auditory and vestibular systems, their central connections and their perception in the central nervous system. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines.
