A hungry and thirsty rat spends 40% of its time lever pressing for food and 60% of its time lever pressing for water. Because it is pressing more for water, water appears to be more reinforcing than food. What additional factors need to be considered, according to the field of behavioral economics?
A) Food and water are not necessarily substitutable and the demand for each can change within a session.
B) The prices of food and water (i.e., the effort required to get one or the other) can vary.
C) Food and water each has a different capacity to reinforce.
D) No additional factors need to be considered, since food and water, like most primary reinforcers, are of more or less equal value and inelastic under equal states of drive.
