Step-by-step explanation:
The type of learning illustrated in this example is taste aversion. Taste aversion is a form of classical conditioning where an organism develops an aversion to a particular taste or food after it becomes associated with a negative stimulus, such as illness or poisoning.
In the case of the rats, they learn to associate the taste of the corn and molasses laced with poison with feeling sick, and as a result, they avoid eating it again in the future.
