Judging the difficulty of perceptual decisions

Posted by klaurent Columbia

Kavli Affiliate: Michael Shadlen | Authors: Anne Löffler, Ariel Zylberberg, Michael N. Shadlen and Daniel M Wolpert | Summary: Deciding how difficult it is going to be to perform a task allows us to choose between tasks, allocate appropriate resources, and predict future performance. To be useful for planning, difficulty judgments should not require completion […]
