Plinko: A Theory-Free Behavioral Measure of Priors for Statistical Learning and Mental Model Updating

  title={Plinko: A Theory-Free Behavioral Measure of Priors for Statistical Learning and Mental Model Updating},
  author={Peter A. V. DiBerardino and Alex Filipowicz and James Danckert and Britt Anderson},
Probability distributions are central to Bayesian accounts of cognition, but behavioral assessments do not directly measure them. Posterior distributions are typically computed from collections of individual participant actions, yet are used to draw conclusions about the internal structure of participant beliefs. Also not explicitly measured are the prior distributions that distinguish Bayesian models from others by representing initial states of belief. Instead, priors are usually derived from… Expand


Bayesian Fundamentalism or Enlightenment? On the explanatory status and theoretical contributions of Bayesian models of cognition
It is argued that the expressive power of current Bayesian models must be developed in conjunction with mechanistic considerations to offer substantive explanations of cognition, and this unification will better facilitate lasting contributions to psychological theory, avoiding the pitfalls that have plagued previous theoretical movements. Expand
Alterations in choice behavior by manipulations of world model
It is shown that “probability matching”—a consistent example of suboptimal choice behavior seen in humans—occurs in an optimal Bayesian model-based learner using a max decision rule that is initialized with ecologically plausible, but incorrect beliefs about the generative process for outcomes.

Bayesian just-so stories in psychology and neuroscience.
It is argued that many of the important constraints in Bayesian theories in psychology and neuroscience come from biological, evolutionary, and processing considerations that have no adaptive relevance to the problem per se. Expand
An Approximately Bayesian Delta-Rule Model Explains the Dynamics of Belief Updating in a Changing Environment
The results suggest that the brain adaptively regulates the influence of decision outcomes on existing beliefs using straightforward updating rules that take into account both recent outcomes and prior expectations about higher-order environmental structure. Expand
Dissociable effects of surprise and model update in parietal and anterior cingulate cortex
A mathematical and neuroanatomical model of how brains adjust to change in their environment is presented that may inform the understanding of neurological disorders in which this adjustment process fails and the dissociation of functional roles between regions within the reorienting/reprogramming network is understood mechanistically. Expand
Functionally Dissociable Influences on Learning Rate in a Dynamic Environment
Computational modeling, psychophysics, and fMRI are used to show that adaptive learning is not a unitary phenomenon in the brain, but can be decomposed into three computationally and neuroanatomically distinct factors that were evident in human subjects performing a spatial-prediction task. Expand
Rejecting Outliers: Surprising Changes Do Not Always Improve Belief Updating
The ubiquity of the notion that surprising environmental changes are always positively related to updating is tested, using a novel task based on the game Plinko to provide a novel and more nuanced representation of the relationship between surprise and updating that should be considered in models of dynamic decision-making. Expand
The relative merit of empirical priors in non-identifiable and sloppy models: Applications to models of learning and decision-making
It is concluded that researchers should invest additional efforts in improving the informativeness of their experimental designs, as many of the problems associated to impoverished designs cannot be alleviated by modern statistical methods alone. Expand
Empirical priors for reinforcement learning models
Abstract Computational models of reinforcement learning have played an important role in understanding learning and decision making behavior, as well as the neural mechanisms underlying theseExpand
Optimal Predictions in Everyday Cognition
This work examined the optimality of human cognition in a more realistic context than typical laboratory studies, asking people to make predictions about the duration or extent of everyday phenomena such as human life spans and the box-office take of movies. Expand
