3D shape perceptionRecent research has shown that people can perceive the shape of objects, even when the objects are not directly perceptible (for instance, when draped in cloth). These findings present a challenge to existing theories of shape perception, which are based on the use of surface cues alone. Yildirim et al. present a computational model of three-dimensional shape perception that integrates intuitive physics and analysis-by-synthesis to explain how shape can be inferred both when surface object cues are available and when they are not (as in cloth draping).

Conceptual bootstrappingHow does the mind bootstrap its way to complex concepts? Across four experiments, Zhao et al. show that a key feature of the acquisition of complex concepts is the incremental construction of compositional representations. The authors then develop a model of conceptual bootstrapping, which captures the process of learning complex concepts by recursively combining simpler concepts.
