Cognitive science again considers the mind as a subject for investigation, using the tools of evolutionary psychology, linguistics, computer science, philosophy, behaviorism, and neurobiology.
Behaviorism had dominated the psychology until the 1950s when new developments in a variety of fields overturned behaviorist theory in favor of a cognitive theory.
Despite the introduction of nonverbal communication in the 1800s, the emergence of behaviorism in the 1920s paused further research on nonverbal communication.
