We assessed the effect of specificity of speaker information about an object on three-year-olds' word mappings. When children heard a novel label followed by specific information about an object at exposure, children subsequently mapped the label to that object at test. When children heard only specific information about an object at exposure, they inferred that the label applied to a different object at test. Finally, non-specific information did not assist children in mapping a word to an object. Thus, children use speaker information as a word-mapping cue but this information is interpreted differently depending on how the discourse is initiated.
我们评估了关于一个物体的说话者信息的特异性对三岁儿童单词映射的影响。当儿童在接触时听到一个新标签后跟随着关于一个物体的特定信息，他们随后在测试中将该标签映射到那个物体上。当儿童在接触时只听到关于一个物体的特定信息，他们在测试中推断该标签适用于另一个物体。最后，非特定信息无助于儿童将单词映射到物体上。因此，儿童将说话者信息用作单词映射线索，但根据话语的起始方式，该信息的解释有所不同。
