摘　　要：本研究采用背景线索效应范式,通过隐马尔可夫模型以数据驱动的方法考察重复场景和新异场景在眼动模式上的差异。结果发现,重复场景与新异场景的眼动模式存在显著差异,主要体现在重复场景中被试有更高的概率从注视点直接转移到目标上。此外通过变分贝叶斯期望最大化对被试的眼动序列进行聚类发现,被试存在全局搜索与定向搜索两种眼动模式,且这种眼动模式不受重复场景和新异场景的影响。In this study,the contextual cueing effect paradigm was used and a data-driven approach with hidden Markov model(HMM)was employed to investigate differences in eye movement patterns between different scenes and individuals.The results showed significant differences in eye movement patterns between repeated and novel scenes,primarily characterized by a higher likelihood of direct saccades to the target in repeated scenes.Furthermore,the analyses of variational Bayesian expectation maximization(VBEM) for clustering fixation sequences showed that participants exhibited two distinct eye movement patterns,that is,global search mode and directed search mode,regardless of whether the scene was repeated or novel.
