Supporting data for “Individual Differences in Eye Movements are Associated with Individual Differences in Face Perception: Evidence from Behavioral Performance and Neural Responses”

This dataset contains the supporting data for the thesis titled “Individual Differences in Eye Movements are Associated with Individual Differences in Face Perception: Evidence from Behavioral Performance and Neural Responses”. Although all faces have similar configurations of features, individuals show different patterns of eye movements when viewing faces. Some people have a preference to scan the eyes, while others avoid looking at the eyes but fixate on the nose and mouth. However, it is poorly understood whether individual differences in eye movements indicate (or are indicators of) different abilities and neural mechanisms to process faces. In the thesis, I compared individual differences of eye movements in multiple aspects of behavioral performance and neural responses. In Study 1, I compared the holistic face processing between those two eye-movement groups. In Study 2 and Study 3, I explored whether eye-movement patterns modulated face identification performance, and the related neural responses, as a function of fixation location on faces. In Study 4,I explored whether the upper-focused group and the lower-focused group have advantages of using high spatial frequencies (HSF) information and low spatial frequencies (LSF) information of faces, respectively. In the dataset, four files are included corresponding to four studies in the thesis separately. Eye movements data, behavioral performance data, and Event-related Potentials data are included.

本数据集包含了题为《眼动差异与面部感知差异的相关性：基于行为表现和神经反应的证据》的论文所支持的数据。尽管所有面部均具有相似的特征配置，个体在观察面部时却表现出不同的眼动模式。部分人倾向于扫描眼部，而另一些人则避免注视眼部，转而聚焦于鼻部和嘴部。然而，个体眼动差异是否表明（或作为）不同处理面部的能力和神经机制尚缺乏深入理解。在论文中，我比较了在行为表现和神经反应的多个方面中眼动差异。在研究1中，我对比了两种眼动群体在整体面部处理方面的差异。在研究2和研究3中，我探讨了眼动模式是否调节了基于面部注视位置的识别表现及其相关的神经反应。在研究4中，我探讨了上焦点组和下焦点组是否在利用面部的高空间频率（HSF）信息和低空间频率（LSF）信息方面具有优势。该数据集中包含了与论文中四个独立研究相对应的四份文件。其中包含了眼动数据、行为表现数据和事件相关电位数据。
