what focuses on the development of psychological tests
Personality psychology is a branch of psychology that studies personality and its variation among individuals.iology plays a very important role in the development of personality. The study of the biological level in personality psychology focuses primarily on identifying the role of genetic determinants and how they mold individual personalities.
Psychological testing also owes as much to early psychiatry as it does to the laboratories of experimental psychology. The examination of the mentally ill around the middle of the last century resulted in the development of numerous early tests.
