The major breakthrough in the study of dreams came in 1953 when researchers Eugene Aserinsky and Nathaniel Kleitman studied and discovered what happens when a person falls asleep.They found that the body enters into a psycho-physiological state in intervals of 90 minute cycles during sleep. This physiological state consists of heightened brain activity, Rapid Eye Movement (REM), increased breathing, a temporary paralysis of the body and genital engorgement. Through experiments, they confirmed that these physiological observations were the result of the person being in the dream state.
The correct answer is; criterion validity.
Further Explanation:
Karen developed the test so that she can measure the hostility in her workplace. She used previous employees who had been terminated on the basis of anger management issues. This has a high degree of criterion validity.
Her test is based on the prediction of an outcome and not on just factual information. This does work in some cases but only when the behavior closely matches the behavior of a previous case used in developing the test. If the cases are not very similar the test may not be conclusive.
