我们提出了一种利用阅读过程中眼球运动的行为痕迹来确定学习者第二语言熟练程度的新颖方法。我们的方法提供基于独立眼动追踪的英语水平分数,反映了学习者在阅读中的注视模式与以英语为母语的人的相似程度。我们表明,我们的分数与标准化英语能力测试密切相关。我们还证明,注视信息可用于准确预测此类测试的结果。当测试者看到一组句子时,我们的方法会产生最强的性能,并且我们有来自其他读者的眼球追踪数据。然而,即使使用眼球追踪来处理先前尚未收集眼球运动数据的句子,它仍然有效。通过将熟练程度作为普通阅读过程中眼球运动的自动副产品得出,我们的方法为第二语言熟练程度评估提供了一种潜在有价值的新工具。更广泛地说,我们的结果为未来从阅读行为痕迹推断读者特征的方法打开了大门。
We present a novel approach for determining learners’ second language proficiency which utilizes behavioral traces of eye movements during reading. Our approach provides stand-alone eyetracking based English proficiency scores which reflect the extent to which the learner’s gaze patterns in reading are similar to those of native English speakers. We show that our scores correlate strongly with standardized English proficiency tests. We also demonstrate that gaze information can be used to accurately predict the outcomes of such tests. Our approach yields the strongest performance when the test taker is presented with a suite of sentences for which we have eyetracking data from other readers. However, it remains effective even using eyetracking with sentences for which eye movement data have not been previously collected. By deriving proficiency as an automatic byproduct of eye movements during ordinary reading, our approach offers a potentially valuable new tool for second language proficiency assessment. More broadly, our results open the door to future methods for inferring reader characteristics from the behavioral traces of reading.
