Rats' Choice in a Coordination Task.

- Abstract
We designed a free-operant choice procedure that represents a technical improvement to assess the control of mutual reinforcement contingencies over the choice of coordinated behavior. We demonstrate the advantages of the new procedure with 8 rats that were trained to continuously move a steel ball from end to end of a gutter. Subjects were assigned to pairs and had to choose between 2 response options: 1 in which reinforcement was contingent upon an individual response and another in which reinforcement depended on the coordination of intra-pair behavior. We evaluated (a) the effect of reinforcement magnitude over the distribution of responses and (b) the role of behavioral cues on the rats' coordinated actions via dividing the experimental chamber in 2 compartments with a clear/opaque partition. The coordinated actions were more likely when the larger reinforcer was initially associated with the mutual reinforcement option. The visual interaction between subjects did not impact their coordinated actions. The possibility to control organisms' preference for social or nonsocial alternatives opens potential lines of research, such as identifying how the coordination of activities combines with the future value of outcomes to produce stable cooperative equilibria.
