Question

Dr. Imanut wants to examine whether a new drug increases the maze-running performance of older rats. Dr. Imanut teaches two groups of older rats to find a piece of tasty rat chow in the maze. One group of rats is given the new drug while they are learning the maze. The second group is not given the drug. One week after having learned the maze he retests

the rats and records how long it takes them to find the rat chow. LIST
ATLEAST TWO CONDITIONS ARE KEPT CONSTANT.

Answer 1

At least two conditions that should be kept constant in Dr. Imanut's experiment are the maze layout and the size and quality of the rat chow reward to ensure a valid study.

Step-by-step explanation:

In Dr. Imanut's experiment to examine if a new drug increases the maze-running performance of older rats, it is important to keep certain conditions constant to ensure a controlled and valid study. At least two conditions that need to be kept constant are:

• The maze's layout and complexity - to ensure that all rats have an equal cognitive challenge.
• The amount of motivation, which in this case would be the size and quality of the tasty rat chow used as a reward - to ensure uniform motivation for maze completion.

By maintaining these conditions, researchers can attribute any differences in performance to the effect of the drug, rather than to other variables.
