Early language input is far from uniform, even among children learning the same language. For instance, while some children are exposed to a single accent in their linguistic environment, others have routine exposure to multiple accents. Nonetheless, few studies have taken this into account when examining word recognition, and none has examined this issue in infants prior to the emergence of phonological constancy (∼18 months). This study demonstrates that daily exposure to multiple accents strongly impacts infants' performance in a laboratory word form recognition task. Accent variability in the input thus needs to be carefully considered when studying speech development.
早期语言输入远非统一，即使是在学习同一语言的儿童中也是如此。例如，一些儿童在其语言环境中接触到单一口音，而另一些儿童则经常接触多种口音。然而，在研究单词识别时，很少有研究考虑到这一点，并且在语音恒常性出现之前（约18个月），没有研究在婴儿中考察过这个问题。本研究表明，每天接触多种口音会强烈影响婴儿在实验室单词形式识别任务中的表现。因此，在研究语音发展时，需要仔细考虑输入中的口音变异性。
