The scientific status of American psychology in 1900.

In 1900, psychologists were attempting to define themselves and searching for their role among both academic and non-academic public. The success of experimental methods served to advance their position as exemplary scientists, although, as the authors argue in this article, other factors were also important. First, the issue of measurement involved many disagreements about the tools needed to measure psychological constructs or even whether psychologists should measure anything at all. Second, the relationship between the brain and psychological constructs enhanced psychology's status for some, whereas others felt that psychologists should stay away from such topics. Parallels with present-day concerns among psychologists are addressed at the end of the article.
