For honors students who declare Psychology as their primary major beginning May 2016 or later, the answer is yes.  All psychology majors, including honors students, are now required to take Psych 392A, Junior Writing!   

If you declared the Psychology major prior to May 2016, you can still substitute two Psychology Honors courses (including those that count toward the Psychology Departmental Honors requirements) for this requirement, and therefore you do not need to take a Junior Writing course.
