Ear Hear:单侧和双侧听力损失的儿童的言语感知和单词学习

最近,有研究人员调查了单侧听力损失对儿童感知熟悉单词以及学习和保留新单词能力的影响。因为单侧听力损失的儿童使用单耳接受全部听觉输入,研究人员预计他们的表现与听力正常的儿童一致,而不是中度双侧听力损失的儿童。

研究包括了36名双侧听力正常的学龄儿童,11名中度双侧听力损失的儿童,以及11名轻度至深度单侧听力损失的儿童(6名右耳,5名左耳)。一半听力正常的儿童和三分之二的单侧听力损失儿童来自西班牙语/英语双语家庭。11名双侧听力损失的儿童中,有1名来自西班牙语/英语双语家庭。所有的儿童都完成了英语和西班牙语的单词识别测试以及第二天的单词记忆测试。

结果表明,英语和西班牙语的单词识别能力在不同组别中没有差异。三种语言中,听力正常的儿童对无意义单词的学习和保持率最高。单侧和双侧听力损失的儿童与听力正常的同龄人一样学习和记忆英语无意义词,但西班牙语和阿拉伯语无意义词的学习和记忆表现却因双耳听力损失而显著下降。

最后,研究人员指出,在一只耳朵有完整的听觉表征的情况下无法学习和保留新单词,表明了单侧和双侧听力损失的儿童可能有一个共同的特点,即在中枢听觉系统层面存在障碍
