汉语母语儿童和成人视听双通道英语语音知觉的训练研究

本研究通过前测-训练-后测的实验程序,对22名五年级小学生和29名大学一年级学生在不同测查条件下知觉英语辅音/s/和/θ/的可塑性情况进行了考察和比较。两个年龄阶段被试在前后测中均接受纯听、视听一致、视听不一致和纯视条件下的测查,训练时两个年龄阶段被试中分别有一半接受纯听训练,另一半接受视听训练,训练时间历时10天,每天30分钟左右。对训练效果的分析发现:(1)接受纯听和视听训练的五年级学生在纯视测查条件下知觉英语辅音/s/和/θ/的提高率有显著差异,视听训练被试显著高于纯听训练被试,在其他条件下没有显著差异;(2)接受两种训练的大学生在所有条件下知觉英语辅音/s/和/θ/的提高率都没有显著差异。说明儿童表现出了更强的视听双通道语音知觉的可塑性。

The Training Study of Chinese Children and Adults' Audiovisual English Phonetic Perception

With 22 primary school students in Grade 5 and 29 freshmen as the subjects,the study explored the effective way for the Chinese children and adult to discriminate difficult English phonemes.In the pre-and post-testing,all the subjects were required to discriminate/s/and/θ/in the audio-only,audio-visual congruent,audio-visual incongruent and visual-only modality.Then half of the subjects received the audio-only training,and another half received audiovisual training,the training process lasted for ten days,and thirty minutes each day.The results showed that:(1)After training,the children received audiovisual training performed significantly better than those received audio-only training in the visual testing modality,there was no difference in other testing modality;(2)In all of the testing modality,there were no significant differences between the adults received audio-only training and audiovisual training.The results showed that,compared with the adults,children showed more strong plasticity of audiovisual phonetic perception.
