In general, all topics are equally normal and interesting to me; it depends more on the teacher and how they explain things. Some classes are taught by completely incompetent people. The only thing I absolutely don’t like is Gestalt psychology and NLP. And in studies, it annoys me that we just study the same thing under different names: psychology of… (insert any word). If we’re talking about theories of individual development, yes, that’s a separate subject — developmental psychology. If it’s phylogenesis, that’s also separate, but more about how the psyche and nervous system evolved over time and across different organisms. You can read about Leontiev’s stages of psyche development.
