Structure and knowledge effects on amodal completion

This dataset was procured as a part of the research project entitled "Structure and Knowledge Effects on Amodal Completion," conducted between the years 2021 and 2022. The central objective of this project was to delve into the interplay between low-level structural phenomena (e.g., linear interpolation) and high-level cognitive factors (e.g., familiarity) within the context of amodal completion. This investigation was executed by employing a state-of-the-art fMRI repetition suppression paradigm in conjunction with the examination of naturalistic objects that were partially occluded. More specifically, the study explored the extent to which distinct cortical visual regions, such as the early visual cortex and the lateral occipital complex (LOC), were implicated in the process of amodal completion. The dataset comprises data from 34 subjects, each of whom participated in the main task, an LOC localizer task, and a retinotopy run. In addition to the fMRI data, eye tracking data was collected.本数据集采自2021至2022年间开展的题为《结构与知识对非模态完成（amodal completion）的影响》的研究项目。该项目的核心目标为深入探究非模态完成场景下，低级视觉结构现象（如线性插值）与高级认知因素（如熟悉度）之间的交互机制。本研究采用当前前沿的功能磁共振成像（fMRI）重复抑制范式，结合对部分遮挡自然物体的观测实验开展研究。 具体而言，本研究探讨了早期视觉皮层、外侧枕叶复合体（lateral occipital complex, LOC）等不同皮层视觉区域在非模态完成过程中的参与程度。本数据集包含34名被试的数据，每名被试均完成了主任务、LOC定位任务以及视网膜拓扑定位扫描。除功能磁共振成像数据外，本数据集还采集了眼动追踪数据。
