Some metacontingency experiments have been working with intermittent cultural consequences in analogue ways to operant ratio schedules. The transition from lower ratio to higher ratio sometimes were followed by a slight instability in the previous selected cultural practice. Only one experiment showed a ratio strain from continuous production of cultural consequence to an analogue of VR2. In all experiments, the raise in ratio was gradual and only ratios 2 and 3 were used. To access some variables that can contribute to the ratio strain, two experiments were conducted. Subjects had the task to insert numbers in a computer game gaining both individual and/or cultural consequences. The elder subjects were substituted for new ones during all experiments. In both experiments, after a period of selection, the ratio for cultural consequence liberation was increased to 2, than, after a stability criterion has been achieved, the ratio was abruptly increased to 10. In the first experiment there was no changes in the aggregate production when the ratio was raised and then the metacontingency was discontinued (analogue of operant extinction). The pattern of production continued for a long period of extinction until the pattern dismisses. The second experiment showed a ratio strain when the ratio was raised from 2 to 10. The results were discussed in terms of different forms of cultural transmission, the format of rules generated by the subjects and the contact with the cultural consequence
