    "abstract": "What hierarchical structures do people use to encode visual\ndisplays? We examined visual working memory’s priors for\nlocations by asking participants to recall the locations of\nobjects in an iterated learning task. We designed a nonparametric\nclustering algorithm that infers the clustering\nstructure of objects and encodes individual items within this\nstructure. Over many iterations, participants recalled objects\nwith more similar displacement errors, especially for objects\nour clustering algorithm grouped together, suggesting that\nsubjects grouped objects in memory. Additionally,\nparticipants increasingly remembered objects as lines with\nsimilar orientations and lengths, consistent with the Gestalt\ngrouping principles of continuity and similarity. Furthermore,\nthe increasing tendency of participants to remember objects as\ncomponents of hierarchically organized lines rather than\nindividual objects or clusters suggests that these priors aid the\nperception of higher-level structures from ensemble statistics",
