Doubly 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 کاملA 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 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 کاملA Bayesian Attractor Model for Perceptual Decision Making
Even for simple perceptual decisions, the mechanisms that the brain employs are still under debate. Although current consensus states that the brain accumulates evidence extracted from noisy sensory information, open questions remain about how this simple model relates to other perceptual phenomena such as flexibility in decisions, decision-dependent modulation of sensory gain, or confidence ab...
متن کاملConfidence-based Representation in Decision Making
ion (derived from Latin abstrahere “to strip off, remove forcibly”) is “the process which allows people to consider what is relevant and to forget a lot of irrelevant details which would get in the way of what they are trying to do” [Giunchiglia and Walsh, 1992]. Abstractionbased processes are pervasive in human reasoning. The earliest and most common use of abstraction was in problem solving. ...
