For a playful yet pretty interesting take on "psychogenesis" I recommend reading Diaspora by Greg Egan.

Also, we are born with very good models (for faces, cognition of human languages + speaking and hearing them, seeing things on Earth, movement coordination, other cognitive fundamentals, like counting, categorization, and so on) plus all of that really well packaged as a starter kit, a do-it-yourself general intelligence, with amazing supervisory framework (parents, peers, society, reflective optimization about one's actions) and reinforcement (emotions, memory coding is waaay too drastically modulated by emotions).

And we're still not sure what else is in there, how all this communicates. What's the operating system of consciousness? (We "know" that consciousness is just a "program", but is it the main thread, is it a scheduler, what's the right mental model for understanding the interaction of brain faculties, components of cognition and consciousness itself?)
