MARINA DEL REY, Calif., Aug. 16 (UPI) -- Psychologist Robert M. Taylor, author of the Taylor-Johnson Temperament Analysis Test, died at his home in California, the Los Angeles Times said. He was 88.
Taylor, a former director of the American Institute of Family Relations, developed the test with colleague Lucille Morrison for use in marriage and family counseling. The test, which contains 180 questions that measure personality traits, was based on an earlier test by psychologist Roswell H. Johnson.
The newspaper said Taylor's test was made widely available in 1966 and is now used by thousands of marriage and family counselors.
"In his years of working with couples, my father saw that the test was a quick, efficient way to capture a picture of their strengths and their possible problems," daughter Jamie Taylor Werner told the newspaper. "Showing a couple the results of the test was like showing them an X-ray."
