On the law of effect.

abstract：:To study how effort affects reward value, we replicated Fortes, Vasconcelos and Machado's (2015) study using an adjusting-delay task. Nine pigeons chose between a standard alternative that gave access to 4 s of food, after a 10 s delay, and an adjusting-delay alternative that gave access to 12 s of food after a delay ...
