Towards more human-like language in multi-agent communication Recent research has trained artificial agents to communicate with each other via task-oriented language, for the dual aims of (1) improving agent collaboration and (2) studying language evolution in artificial settings.  This talk will describe two studies of the emergent linguistic phenomena in these multi-agent systems. First, pragmatics: I’ll […]

What underlies rapid learning and out-of-distribution transfer in humans? Humans can sometimes learn a procedure from one or a small number of examples and then apply what they have learned to a much larger range of examples. Here, we explore this ability as it arises in learning a strategy from Sudoku. Participants naive to Sudoku […]

Texture-like representations support object perception in dCNNs and the human brain.  Humans identify objects by the presence of complex visual features arranged in particular configurations. How does the visual system represent objects? In one widely held account (“holistic object” hypothesis), the ventral temporal cortex (VTC) explicitly represents objects as a whole, such that it is […]

When the ventral visual stream is not enough: A deep learning account of medial temporal lobe involvement in perception Animals seamlessly integrate sensory activity with previously encountered, behaviorally relevant experience. Neuroanatomical structures within the medial temporal lobe, such as perirhinal cortex (PRC), are known to enable these memory-related behaviors. Yet there is an enduring debate […]

Spatiotemporal population receptive field model in human visual cortex  Visual scenes we experience contain objects that move over positions and time. To interpret dynamic changes in the visual scene, our visual system requires representations of both space and time. However, previous population receptive field (pRF) models focused on the spatial domain of the stimulus. Here, […]

The white matter connectivity of the ventral stream in childhood Ventral temporal cortex consists of category selective regions that fall in consistent anatomical locations across individuals and over development. This consistency has many to wonder about the organizing principle(s) of the ventral stream. While there have been functional hypotheses (foveal/peripheral bias, real-world size and curvature), […]
