Div. 25 (Behavior Analysis) promotes basic research, both animal and human, in the experimental analysis of behavior and the application of the results of such research to human affairs. It cooperates with other disciplines whose interests overlap with those of the division. The division publishes Division 25 Recorder, a newsletter distributed two times a year to all members and affiliates, who also receive PsycSCAN: Behavior Analysis & Therapy, published quarterly. Div. 25 participates in the APA Annual Convention, sponsoring individual speakers, symposia, and special events, such as receptions and an annual dinner. Div. 25 is also an active co-sponsor of social hours and presentations dealing with the field of behavior analysis.

The division was founded in 1964 to promote basic and applied research to stimulate exchange of information concerning such research, and to work with other disciplines whose interests overlap those of Division 25. Along with these original objectives, today's division addresses contemporary issues related to the philosophy, research, and applied practice of Behavior Analysis. Originally intended to serve as a voice for behavior analysis within the APA, Div. 25 also is involved with promoting behavior analysis within the larger society.
