<p>Behavioral psychology and cognitive science are quite different approaches.
Most psychology departments are dominated by cognitive psychology and neuroscience. If you are interested in the field called the Experimental Analysis of Behavior (i.e., operant psychology), which is what I understand by “behavioral psychology” then you’ll find programs at Kansas, Florida, Nevada-Reno, Western Michigan and some others. You’ll find researchers who specialize in EAB at a broader range of schools. Check the listing for the editorial board of the Journal of Experimental Analysis of Behavior to get an idea of where some of these researchers are located. [Journal</a> of the Experimental Analysis of Behavior - Editorial Board - Wiley Online Library](<a href=“http://onlinelibrary.wiley.com/journal/10.1002/(ISSN)1938-3711/homepage/EditorialBoard.html]Journal”>http://onlinelibrary.wiley.com/journal/10.1002/(ISSN)1938-3711/homepage/EditorialBoard.html). If you are interested in the field called Applied Behavior analysis, you’ll find many more schools with programs in that area. Check the website of the Association for Behavior Analysis International for some of those: [Accredited</a> Programs - Association for Behavior Analysis International](<a href=“http://www.abainternational.org/accreditation/accredited-programs.aspx]Accredited”>Welcome - Association for Behavior Analysis International) and the Journal of Applied Behavior Analysis ([Archive</a> of “Journal of Applied Behavior Analysis”.](<a href=“http://www.ncbi.nlm.nih.gov/pmc/journals/309/]Archive”>Archive of "Journal of Applied Behavior Analysis". - PMC)).</p>
<p>You won’t find too many departments at the undergraduate level that will have a subspecialty in behavioral psychology. Most will offer a major in general psychology. You might be able to do some research as an undergrad with faculty members who do take a behavioral approach, though. Even if you did specialize in behavioral psychology at the graduate level, exposure to other subspecialties and approaches is beneficial. Among other courses you will take, make sure you take coursework that focuses on learning/conditioning and animal behavior. You also would benefit from coursework in economics (including behavioral economics) and philosophy, among other areas.</p>
