"Here, we trained rats, housed in pairs or in isolation, in a touch screen chamber to detect the association between four different light signals on the screen and accompanied reward and punishment outcomes arranged in different schedules," the researchers said in a paper.
The researchers concluded that all rats significantly changed their preferences toward more risky choices when they were exposed to and challenged with cocaine, indicating that a pre-existing trait toward risk and environmental conditions interacts to affect the quality of rat decision-making.
