Sensorimotor priors in nonstationary environments.
In the course of its interaction with the world, the human nervous system must constantly estimate various variables in the surrounding environment. Past research indicates that environmental variables may be represented as probabilistic distributions of a priori information (priors). Priors for environmental variables that do not change much over time have been widely studied. Little is known,...
متن کاملInferring Visuomotor Priors for Sensorimotor Learning
Sensorimotor learning has been shown to depend on both prior expectations and sensory evidence in a way that is consistent with Bayesian integration. Thus, prior beliefs play a key role during the learning process, especially when only ambiguous sensory information is available. Here we develop a novel technique to estimate the covariance structure of the prior over visuomotor transformations--...
متن کاملSensorimotor priors in non - stationary environments 2 3 Abbreviated Title : Priors in non - stationary environments
24 In the course of its interaction with the world, the human nervous system must constantly estimate 25 various variables in the surrounding environment. Past research indicates that environmental variables 26 may be represented as probabilistic distributions of a priori information (priors). Priors for 27 environmental variables that do not change much over time have been widely studied. Litt...
متن کاملRepresenting multiple object weights: competing priors and sensorimotor memories.
When lifting an object, individuals scale lifting forces based on long-term priors relating external object properties (such as material and size) to object weight. When experiencing objects that are poorly predicted by priors, people rapidly form and update sensorimotor memories that can be used to predict an object's atypical size-weight relation in support of predictively scaling lift forces...
متن کاملData-dependent probability matching priors
We consider a general class of empirical-type likelihoods and develop higher order asymptotics with a view to characterizing members thereof that allow the existence of possibly data-dependent probability matching priors ensuring approximate frequentist validity of posterior quantiles. In particular, for the usual empirical likelihood, positive results are obtained. This is in contrast with wha...
