A Bayesian Framework for Modeling Confidence in Perceptual Decision Making
The degree of confidence in one’s choice or decision is a critical aspect of perceptual decision making. Attempts to quantify a decision maker’s confidence by measuring accuracy in a task have yielded limited success because confidence and accuracy are typically not equal. In this paper, we introduce a Bayesian framework to model confidence in perceptual decision making. We show that this model...
متن کاملDoubly Bayesian Analysis of Confidence in Perceptual Decision-Making
Humans stand out from other animals in that they are able to explicitly report on the reliability of their internal operations. This ability, which is known as metacognition, is typically studied by asking people to report their confidence in the correctness of some decision. However, the computations underlying confidence reports remain unclear. In this paper, we present a fully Bayesian metho...
متن کاملConfidence-related decision making.
Neurons have been recorded that reflect in their firing rates the confidence in a decision. Here we show how this could arise as an emergent property in an integrate-and-fire attractor network model of decision making. The attractor network has populations of neurons that respond to each of the possible choices, each biased by the evidence for that choice, and there is competition between the a...
متن کاملCALL FOR PAPERS Decision Making: Neural Mechanisms Confidence estimation as a stochastic process in a neurodynamical system of decision making
Wei Z, Wang XJ. Confidence estimation as a stochastic process in a neurodynamical system of decision making. J Neurophysiol 114: 99–113, 2015. First published May 6, 2015; doi:10.1152/jn.00793.2014.—Evaluation of confidence about one’s knowledge is key to the brain’s ability to monitor cognition. To investigate the neural mechanism of confidence assessment, we examined a biologically realistic ...
متن کاملEffects of Cortical Microstimulation on Confidence in a Perceptual Decision
Decisions are often associated with a degree of certainty, or confidence--an estimate of the probability that the chosen option will be correct. Recent neurophysiological results suggest that the central processing of evidence leading to a perceptual decision also establishes a level of confidence. Here we provide a causal test of this hypothesis by electrically stimulating areas of the visual ...
