Ah, the good old days of APFCC! I remember them well.
I used to make spider diagrams - general area of psychology in the middle (e.g. social), then sprouting off from that I'll have obedience, minority influence, majority influence etc (whatever it is you're doing). From each of them, I'd sprout off the certain studies, one colour for a 'supporting' study to the theory, and a different colour for studies 'against' the theory. Then for each study, just do quick APFCCs - trigger words/very simple descriptions etc.
I hope that helps!
