Learning is essential in everyday life. Whenever we make a choice, we need to know whether to repeat it or to try a different course of action. But what makes us learn or prevents us from learning? A ...

In the other session, participants only got "reward feedback," with successful shots being artificially shown pocketing, while failed shots gave no visual results. The goal was to see whether the ...
