1. Psychology is a useful tool for testing the accuracy of common sense and intuition.
2. If a study demonstrates that the treatment caused a change in behavior, then the study has internal validity.

4. Psychological constructs are mental states that can be directly observed and measured.
5. Reaction time is a psychological construct.
6. You can infer a psychological construct from observable behavior.

8. If you can demonstrate that your physical manipulation of a variable such as warmth is pure, you can be confident that your manipulation is also pure at the psychological level.
9. If participants know what the researcher is looking for, construct validity may be compromised.
10. External validity is only a concern if your sample size is too small.
