TLDR
2 groups of 60 rats received either 75 or 285 runs in a runway before being given a choice between freeloading from a dish of pellets in the start box or running the maze for a single pellet, showing less willingness to perform the operant than the 75-trial Ss.Abstract:
2 groups of 60 rats received either 75 or 285 runs in a runway before being given a choice between freeloading from a dish of pellets in the start box or running the maze for a single pellet The 285-trial Ss showed less willingness to perform the operant than the 75-trial Ss This is opposite to what Jensen (1963) had found in the Skinner box Schedule of reinforcement (100 vs 50%) during training did not significantly affect freeloading scoresread more

Free food or earned food? A review and fuzzy model of contrafreeloading
TL;DR: It is argued that contrafreeloading does not contradict reinforcement theory, provided that the sensory reinforcement obtained from stimuli associated with the earned food is also taken into account.

The free food (contrafreeloading) phenomenon: A review and analysis
TL;DR: Analysis of the literature suggests that responding for food in the presence of free food is importantly controlled by stimulus change attendant upon response-dependent food presentation.

“Freeloading” in the Skinner Box Contrasted with Freeloading in the Runway
TL;DR: In this paper, three groups of rats were allowed to make either 0, 40 or 285 rewarded bar-pressing responses and then were given a choice between eating pellets from a dish (freeloading) or pressing the bar.

The effect of prior training on the contrafreeloading phenomenon
Barry E. Lentz,Steven L. Cohen +1 more
TL;DR: The data suggest that amount of training affects contrafreeloading and that this variable may be partly responsible for the large variability in responding observed among studies examining responding in the presence of free food.

Responding in the presence of free food: Differential exposure to the reinforcement source
Peter Mitchell,K. Geoffrey White +1 more
TL;DR: In this article, preference in rats for response-contingent reinforcement vs free food was studied as a function of differential exposure to the response-Contingent and free reinforcement sources, and it was demonstrated that the phenomenon of responding for food in the presence of free food is a consequence of prior operant or instrumental training.
