Sampling from external and internal sensations while deciding when to cross a busy road. To ultimately decide whether it is safe to cross, one can sample from external (i.e., from perception) or internal (i.e., memory) sensations. For example, the features, position, motion, and speed of the blue car are gathered from visual perception (on the left). In contrast, these properties of the red car are sampled from working memory (on the right). External and internal sensations are sampled to gradually accumulate evidence until a decision threshold is reached, and the decision is made that it is safe to cross the road.
