Cooperative responding in rats: II. Performance on fixed-ratio schedules of mutual reinforcement

Stimulus control of a social operant

Three pigeon dyads were exposed to a two-component multiple schedule comprised of two tandem variable-interval 30-s interresponse time (IRT) > 3-s schedules in the presence of different stimuli. Pecks to keys by both pigeons of a dyad occurring within 500 ms of one another were required for reinforcement under one tandem schedule (the coordination component), and such coordinated responses were not required under the other (the control component). The terminal link of each schedule ensured that the reinforced coordination response was an IRT > 3 s. Rates of coordinated IRTs > 3 s and total rates of coordinated responses (composed of IRTs > 3 s and IRTs ≤ 3 s) were higher in the coordination components than in either of two different control components in which coordination was not required for reinforcement. This difference in coordinated responses in the presence and absence of the coordination requirement under stimulus control transitorily deteriorated and then was reestablished when the relation between the stimulus and the coordination contingency or its absence was reversed. The results show coordinated responding to function as a discriminated social operant.

Cultural Milieu and Group-Rules in an Elaborated Account of Metacontingencies: Conceptual Analysis and an Illustration in a COVID-19 Psychological Support Project

The elaborated account of the metacontingency explicitly incorporated the role of antecedent events (with the concept of cultural milieu or cultural-organizational milieu) and verbal behavior (clearly related to what was termed group-rule generation). We argue that the cultural milieu encompasses two functionally distinct entities: antecedent environmental variables affecting the culturant (the organization members' activities)-what we termed cultural antecedents; and variables affecting the selecting environment or the consumer practices (members external to the organization responsible for producing cultural consequences)-what we termed selecting environment variables. Besides that, we propose that group-rule generation is not an element of a metacontingency distinct from the culturant, but that it describes verbal components of the interlocking behavioral contingencies; and that these verbal components are not present in all culturants but are especially important in more complex ones. We illustrate this conceptual analysis with reference to a COVID-19 psychological support project undertaken at a public university in Brazil and conclude by suggesting theoretical and methodological implications.
