Lifespan Development Seen through Niche Construction Theory.

I will here pick up on a suggestion made by Greve (2023) in this journal, namely that a proper understanding of lifespan development means defending a non-reductionist psychology taking biological processes seriously, but without reducing psychology to physiology. I will here suggest and argue for the use of niche construction theory as a way of providing a psychological theoretical perspective on lifespan development broad enough to contain both naturalistic and normative elements in a non-reductionist manner.
