Dual mechanisms governing reward-driven perceptual learning
In this review, we explore how reward signals shape perceptual learning in animals and humans. Perceptual learning is the well-established phenomenon by which extensive practice elicits selective improvement in one's perceptual discrimination of basic visual features, such as oriented lines or moving stimuli. While perceptual learning has long been thought to rely on 'top-down' processes, such ...
متن کاملBiases of Rational Agents
This paper shows why, in a world with differing priors, rational agents tend to attribute their own success more to skill and their failure more to bad luck than an outsider. It further shows why each agent in a group might think he or she is the best, why an agent might overestimate the control he has over the outcome, and why two agents’ estimated contributions often add up to more than 100%....
متن کاملSocial reward shapes attentional biases.
Paying attention to stimuli that predict a reward outcome is important for an organism to survive and thrive. When visual stimuli are associated with tangible, extrinsic rewards such as money or food, these stimuli acquire high attentional priority and come to automatically capture attention. In humans and other primates, however, many behaviors are not motivated directly by such extrinsic rewa...
متن کاملPerceptual Reward Functions
Reinforcement learning problems are often described through rewards that indicate if an agent has completed some task. This specification can yield desirable behavior, however many problems are difficult to specify in this manner, as one often needs to know the proper configuration for the agent. When humans are learning to solve tasks, we often learn from visual instructions composed of images...
متن کاملPerceptual Biases in Consonant Deletion
We demonstrate that adult English speakers make use of perceptual principles in medial consonant cluster deletion. Cross-linguistically, consonant cluster simplification via deletion is more likely apply to the first consonant rather than the second consonant (if both consonants are of equal sonority). Adult native English speakers, were given a two-alternative forced-choice task in which eithe...
