Quizplus · Accepted Answer

Psychologists in the 20th century primarily provided service to police agencies in the area of cognitive and aptitude testing, such as assessing the suitability of candidates for law enforcement positions and developing selection tests for police recruitment. While stress management, hostage negotiation training, and family counseling may also be areas of involvement for psychologists in law enforcement today, they were not the primary focus in the 20th century.
