2. With which of the following statements would a behaviorist agree?

A. Conscious experiences can be studied in an objective, precise way.
B. In order to understand behavior, one must understand the motives behind the behavior.
C. Behavior can only be explained in terms of phenomenology, that is, an individual's interpretation of experience.
D. Psychology should be the science of behavior that can be observed by others.

Correct answer: D

Rationale: The correct answer is D. Behaviorists argue that psychology should focus on observable behavior that can be studied objectively. Choice A is incorrect because behaviorists do not typically focus on conscious experiences, as they are not directly observable. Choice B is incorrect because behaviorists emphasize that behavior can be understood without delving into internal motives. Choice C is incorrect as behaviorists do not exclusively explain behavior through an individual's interpretation of experience; they focus on observable actions and reactions.

Choice D, Structuralists, studied the basic elements of consciousness rather than its function and purpose.

4. Down syndrome is caused by ________.

A. a chemical imbalance.
B. a gene on the X chromosome.
