    "title": "Alien Bacteria Found on Mars! A Model of Conceptual Change using the\nRe-categorization Paradigm",
    "subtitle": null,
    "abstract": "Many conceptual change theories posit that change occurs due to a variety of cognitive, social, and emotional\nfactors (Dole & Sinatra, 1998; Ohlsson, 2011), however, few theories have tested these claims via computational models of\nconceptual change. In this paper, we present a hierarchical Bayesian model that addresses change processes and their effects\non re-categorization, a form of concept change. Human data from a study using the re-categorization paradigm (Ramsburg &\nOhlsson, 2013) are compared to the computational model. The structure of the human data suggests the ‘non-monotonic’ nature\nof conceptual change (Ohlsson, 2011) as indicated by the best-fit learning curves. For several such curves, model comparisons\nsuggest good fits between the computational simulations and human data. The nonlinear form of the model’s update functions\nlends additional support to concept change as a non-monotonic process. The model is discussed as a “proof of concept” for\nfuture conceptual change modeling endeavors.",
