  • The link between the dynamics of decision formation and movement is unclear. Here the authors reveal a tight relationship between evidence accumulation during perceptual decisions and response trajectories observed in rats and humans.

  • Models of perceptual decision making typically take into account either reactive responses to external stimuli or proactive aspects to decision making. Here the authors found that rat perceptual responses are generated by a combination of the standard evidence accumulation process with a fixed decision boundary, and a separate stochastic boundary collapse triggered by a parallel proactive process.

  • Because our immediate observations are often ambiguous, we must use the context (prior beliefs) to guide inference, but the context may also be uncertain. Here, the authors show that humans can accurately estimate the reliability of the context and combine it with sensory uncertainty to form their decisions and estimate confidence.

  • The authors use a combination of perceptual decision making in rats and computational modeling to explore the interplay of priors and sensory cues. They find that rats can learn to either alternate or repeat their actions based on reward likelihood and the influence of bias on their actions disappears after making an error.

  • Using qualitative and quantitative methods, Baumard et al. build a database of ancient literary fiction. They find that higher levels of economic development are associated with a greater incidence of love in narrative fiction.
