Cognitive science again considers the mind as a subject for investigation, using the tools of evolutionary psychology, linguistics, computer science, philosophy, behaviorism, and neurobiology.

Despite the introduction of nonverbal communication in the 1800s, the emergence of behaviorism in the 1920s paused further research on nonverbal communication.
