How unusual is it for someone to apply to CogSci PhD programs with a research background in artificial intelligence/data science? How should I ask for recommendation letters if my strongest ties are to faculty in Computer Science? I'm mostly interested in computational models of behavior, language processing, decision making, etc.
My BS is cogsci but since I focused more on the computational side during my undergrad, I feel like I might have more knowledge gaps than someone from psychology or neuroscience. I'm a bit hesitant to try for a MA/MS program first since I'm already pursuing a MS in computer science, and I'd really like to jump into some PhD soon.
Edit: Edited the title since "CS" can stand for both computer science and cognitive science, haha.
