Non-native speech is difficult for native listeners to understand. While listeners can learn to understand non-native speech after exposure, it is unclear how to optimize this learning. Experimental subjects transcribed non-native speech and were paid either a flat rate or based on their performance. Participants who were paid based on performance demonstrated improved performance overall and faster learning than participants who were paid a flat rate. These results suggest that exposure alone is not sufficient to optimize learning of non-native speech and that current models of this process must be revised to account for the effects of motivation and incentive.

绩效工资和非母语理解能力：当我们受雇倾听时，我们能学会更好地理解吗？

非母语语音对于母语听众来说很难理解。虽然听众在接触非母语语音后可以学会理解，但目前尚不清楚如何优化这种学习。实验对象转录非母语语音，并按固定费率或根据他们的表现获得报酬。与按固定工资支付的参与者相比，根据绩效支付工资的参与者表现出整体绩效的提高和学习速度的加快。这些结果表明，仅接触不足以优化非母语语言的学习，必须修改该过程的当前模型以考虑动机和激励的影响。
