Data: Fixation duration on natural scenes is explained by memory encoding not processing demand

This dataset (AVS) contains derivative results of simultaneous magnetoencephalography (MEG), eye-tracking, and structural MRI recordings from 5 participants (3 female, 2 male; mean age = 27.8 years, SD = 2.6) performing a natural scene viewing task and verbal captioning task. The dataset is built upon scenes from the Natural Scenes Dataset (Allen et al., 2022), AVS captures the neural dynamics of fixation-locked visual processing across 4,080 natural images with high temporal resolution. The AVS dataset addresses a critical gap in visual neuroscience by providing high-quality neural recordings during active, naturalistic vision. Unlike traditional paradigms requiring central fixation, AVS captures the neural dynamics of self-directed visual exploration.
