Question

In their experiments on the operant conditioning of heart rates, in which the rats were given curare, to immobilize the skeletal muscles, Miller and DiCara were able to do which of the following? (though later attempts at replicating these findings failed)

Answer 1

They discovered "how to control the heart"

Step-by-step explanation:

In concrete, they were able to reinforce heart-rate increase and they were able to reinforce heart-rate decreases, which means they found a way to make a heart start pumping or even to stop the heart.

They also were able to control heart rate with a discriminative stimulus, this means that they could make a heart, for example, go from 100 bpm (beats per minute) to 70 bpm.
