요약The ability to perceive and interpret human body structure from incomplete or ambiguous visual input is central to visual cognition and social understanding. Yet the mechanisms that enable humans to infer coherent body configurations from sparse visual evidence remain an open question in visual cognition. This dissertation investigates the cognitive and computational mechanisms underlying human body perception, focusing on how individuals recognize and reconstruct body poses from partial, occluded, or low-resolution visual input. The research is structured to embody various levels of perceptual complexity, from recognizing isolated body parts to integrating parts into full body poses. Chapter 1 provides an overview of the theoretical foundations of object and body recognition, highlighting the debate between structural description and image-based models, and introducing body perception as a specialized domain of object recognition. Chapter 2, "From Pixels to Parts," compares human performance with deep convolutional neural networks (DCNNs) in recognizing isolated body parts under spatial constraints, revealing shared reliance on part-level structural features and highlighting how both systems scale recognition with increasing spatial context. Chapter 3, "From Parts to Pairs," extends this investigation by examining how recognition of body parts is influenced by their spatial relationships, emphasizing the role of pairwise spatial context in body part identification. Chapter 4, "From Pairs to Pose," delves into the hierarchical nature of body part perception, demonstrating how the visual system integrates local and global information to efficiently reconstruct body poses, and providing evidence for the use of relational knowledge to enhance body perception under varying visual complexity. The findings throughout this dissertation highlight a dynamic, relational framework for body perception, in which both part-level features and structural relationships are crucial for efficient body pose recognition. Together, this research offers novel theoretical insights into how the brain processes body information, advancing our understanding of visual inference and providing a benchmark for evaluating computational models of human body recognition.
