I've been trying to find specific information but that hasn't been easy. I know that I need to find something that psychologically links sight/visual perception to food choice, but I haven't been able to find it yet. What I have found strongly suggests such a link, but doesn't cite any specific scientific link. I have behavioral pattern evidence, but I'd like to have something more science-based since I'm going to try to support an inherently-based rather than conditionally-based connection.
