Decision making is thought to be guided by the values of alternative options and involve the
accumulation of evidence to an internal bound. However, in natural behavior, evidence
accumulation is an active process whereby subjects decide when and which sensory
stimulus to sample. These sampling decisions are naturally served by attention and rapid
eye movements (saccades), but little is known about how saccades are controlled to guide
future actions. Here we review evidence that was discussed at a recent symposium, which …
Decision making is thought to be guided by the values of alternative options and involve the accumulation of evidence to an internal bound. However, in natural behavior, evidence accumulation is an active process whereby subjects decide when and which sensory stimulus to sample. These sampling decisions are naturally served by attention and rapid eye movements (saccades), but little is known about how saccades are controlled to guide future actions. Here we review evidence that was discussed at a recent symposium, which suggests that information selection involves basal ganglia and cortical mechanisms and that, across different contexts, it is guided by two central factors: the gains in reward and gains in information (uncertainty reduction) associated with sensory cues.
