Relational Frame Theory proposes that control by novel
instructions may be understood as control by networks of Same
and Before or After relations. The current paper reports two
experiments in which such control was demonstrated. In
Experiment 1, undergraduate students were first trained to
respond in accordance with Before and After relations and then
trained to respond in accordance with Same and Different
relations. Subjects were then presented with a number of
'instructions' in the form of networks of Same, Different, Before,
and After relations in the absence of reinforcement. Of the 3
students, 2 demonstrated the required performance within two
exposures to the final phase of the experiment. In Experiment 2, 5
of 8 additional subjects who demonstrated instructional control
also did so in the presence of 24 novel stimulus sets without
further training. The implications of these novel and generative
performances for the analysis of instructional control and human
language more generally are considered.
