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.
