The group of rats that would develop a conditioned taste aversion to saccharin-flavored water is "the experimental group initially introduced to saccharin-flavored water."
This is because the experimental group would feel it is the saccharin-flavored water they drank that caused them illness instead of understanding that the radiation could make them ill.
This is based on the findings made by Garcia & Koehling on taste aversion and biological preparedness.
Hence, in this case, it is concluded that "the experimental group initially introduced to saccharin-flavored water" is the group of rats that would cultivate a conditioned taste aversion to saccharin-flavored water.
The full question is:
There were two groups of rats: an experimental group initially introduced to saccharin-flavored water and the control group that was not.
Both groups of rats were then exposed to radiation that made them ill. They were exposed to this just once. Then, both groups were given saccharin-flavored water to see if they would avoid it.
Which group of rats would develop a conditioned taste aversion to saccharin-flavored water?
