In the first phаse оf оur experiment, а rаt was trained tо press a lever. Every time the rat pressed the lever, a small amount of cocaine was injected into its blood stream (which eventually made its way to the rat’s brain). The rat pressed the lever many, many times to obtain cocaine. In the second phase, we allowed the rat to press the lever, just as before, but no cocaine was ever delivered (i.e., pressing the lever in the second phase had no consequence). In the first phase we saw a lot of lever pressing, but in the second phase we saw an initial increase in lever pressing, followed by a gradual reduction in lever pressing. After an hour passed in phase 2, the rat no longer pressed the lever. To improve this study, what do you think the researcher should do next? (1 pt)
