The behavioural consequences are a central concern in psychological research. The most powerful theoretical anchor is Skinner's variable-ratio reinforcement : behaviour is most robustly maintained not by consistent reward but by unpredictable ones. Every scroll is a pull of the lever. The neurobiological substrat...
