The role of uncertainty in attentional and choice exploration.

摘要: The exploitation-exploration (EE) trade-off describes how, when making a decision, an organism must often choose between safe alternative with known pay-off, and one or more riskier alternatives uncertain pay-offs. Recently, the concept of EE has been extended to examination how organisms distribute limited attentional resources several stimuli. This work suggests that rules governing environment are certain, participants learn “exploit” by attending preferentially cues provide most information about upcoming events. However, uncertain, people “explore” increasing their attention all may help in predicting In current study, we examine uncertainty affects using contextual two-armed bandit task, where explore both choice behavior. We find evidence for influence on attention. These findings support idea attention, is primary motivator exploration allocation.
