  • A study in Nature Human Behaviour proposes a biologically plausible algorithm producing near-optimal behaviour in uncertain and volatile environments through computational imprecision. A complementary study in the same issue shows that, depending on context, uncertainty itself guides different decisions and is differentially represented in the brain.

  • Making a good decision often requires the weighing of relative short-term rewards against long-term benefits, yet how the brain does this is not understood. Here, authors show that long-term beliefs are biased by reward experience and that dissociable brain regions facilitate both types of learning.

  • Though people learn that certain choices may be more advantageous, they often do not choose this option. Here, the authors explain this behaviour: people learn how good a choice is relative to the choices it has been associated with previously, and this learning takes place in the striatum.

  • Using single-trial analysis in fMRI, this study shows that activity in brain areas associated with error monitoring and cognitive control differentiates between items that are later remembered correctly vs those where mistakes persist.

  • People slow down reactions after errors, yet it is debated whether the mechanisms behind this slowing are beneficial for future performance. Here, the authors show that EEG measures converge with model predictions supporting a complex but overall beneficial mechanism of post-error slowing.

  • The rostral cingulate zone and the orbitofrontal cortex are active when people monitor the consequences of adaptively changing behavior. A new fMRI study distinguishes their functions, implicating them in situations with different contexts and timing.
