This study was undertaken to determine the effect of linguistic background on scores obtained by native and non-native subjects on two dichotic speech tests in American English, the staggered spondaic word (SSW) and the dichotic consonant-vowel (CV) tests. Thirty subjects whose native languages were either Hindi or Arabic were tested. Test findings were compared to results obtained from 10 native English-speaking subjects. The non-native English speakers showed abnormally high error scores on the SSW test while the native speakers performed with no errors on that test. Performance on the dichotic CV test was comparable for both the native English and the Hindi subjects, while the Arabic subjects performed significantly worse than the two other groups. These data indicate that tests of speech perception using English must be interpreted with caution when administered to non-native English speakers, and that neither the SSW nor the dichotic CV tests may be assumed to be free of linguistic bias.
本研究旨在确定语言背景对以英语为母语和非英语母语受试者在两项美式英语双耳言语测试（交错扬扬格词测试（SSW）和双耳辅音-元音（CV）测试）中所得分数的影响。测试了30名母语为印地语或阿拉伯语的受试者。将测试结果与10名以英语为母语的受试者的结果进行了比较。非英语母语者在SSW测试中表现出异常高的错误分数，而以英语为母语者在该测试中无错误。对于以英语为母语者和印地语受试者来说，双耳CV测试的表现相当，而阿拉伯语受试者的表现明显比其他两组差。这些数据表明，当对非英语母语者进行使用英语的言语感知测试时，必须谨慎解释测试结果，并且不能认为SSW测试和双耳CV测试没有语言偏差。
