Resumen:
The main aim of the study was to assess the effects of varying response
modality in the human allocation of operant responses to different
reinforcement sources using a rapidly changing environment procedure. A
total of nine undergraduate students participated. In each session,
participants were presented with seven independent concurrent variable
interval schedules of reinforcement in an irregular order. Individual
schedules lasted for the delivery of five reinforcers. In Experiment 1,
six students were randomly assigned to two conditions (BO and MT). In
the BO condition, participants pressed buttons on the screen to earn
points. In the MT condition, participants tracked and pressed moving
targets that changed position every 2000 ms. Results showed that
sensitivity to reinforcement developed just for the BO condition. A
second Experiment was conducted, having three participants, and using
the MT condition only. The rate of target position change parameter was
modified to 300 milliseconds. Under those conditions, the development of
sensitivity to reinforcement was observed. However, variable
performances were found. It is concluded that response modality can
affect the development of sensitivity if response requisites to obtain
reinforcement depend on the way the response modality is arranged.
