Recent developments in the assessment of traits

There have been many surveys of personality, temperament, and character tests. The two most outstanding of these are by G. B. Watson ³³⁴ and by P. E. Vernon, ³³⁵ while the whole field of personality has been covered by G. W. Allport and P. E. Vernon ³³⁶ who devoted, in their thorough report, a lengthy section to experimental methods. The last-mentioned appeared in 1930. Watson’s followed shortly after, in 1932, while Vernon’s, which is the most extensive thus far, was published in 1938.
