A cross-sectional, dichotic listening study of 210 right-handed, middle-class children four to ten years old used thirty pairs of one-syllable words and thirty pairs of four-syllable numbers to assess the developmental course of ear asymmetry. A significant decrease in REA for both word and number pairs was found. Although right-ear and left-ear performance both increased with age, the developmental gain in left-ear performance was greater than the gain in right-ear performance, thus resulting in a decrease in REA with age. The results are discussed with respect to investigations which found no change in REA during development and a structural model based on the development of interhemispheric connectivity is proposed to explain the findings.
一项针对210名4至10岁右利手、中产阶级儿童的横断面双耳分听研究，使用了30对单音节词和30对四音节数字来评估耳不对称的发展过程。研究发现，单词对和数字对的右耳优势均显著下降。虽然右耳和左耳的表现都随年龄增长而提高，但左耳表现的发展增益大于右耳表现的增益，因此导致右耳优势随年龄下降。本文结合那些在发展过程中未发现右耳优势变化的研究对结果进行了讨论，并提出了一个基于半球间连接发展的结构模型来解释这些发现。
