Ecological affordances across life stages: An affordance-management framework.

Integrating affordance-management and life-history perspectives, we propose that the perception of ecological affordances-the opportunities and threats an environment poses for goal achievement-varies as people's goal priorities change across developmental life stages. The same environment can be perceived as posing an opportunity at one life stage, but as posing a threat or being irrelevant at other stages, shifting how individuals manage these affordances. By examining environmental dimensions tied to recurring adaptive challenges in human history-genetic relatedness, physical violence, and sex-age ratio-we explore human-environment interactions across the lifespan, offering insights into lifelong flexibility in ecological navigation. Although the interaction between humans and their environments is central to psychological science, its dynamics throughout the lifespan remain unexplored. We consider how ecological affordances—the opportunities and threats an environment poses for one’s goal achievement—can be differently perceived across developmental life stages. Integrating affordance-management and life-history perspectives, we propose that individuals perceive and respond to ecological affordances based on their prioritized goals, which shift systematically as they progress through life stages. The same environment can be perceived as posing an opportunity at one life stage, but as posing a threat or being irrelevant at other stages with different goal priorities. To illustrate the value of this framework, we focus on three environmental dimensions tied to recurring adaptive challenges in human history: genetic relatedness, physical violence, and sex-age ratio. We examine how individuals perceive and navigate ecological affordances across three key life stages—childhood, mating, and parenting—through multiple strategies: (a) recalibrating cognitive and affective attunement to relevant cues, (b) adjusting psychological and behavioral strategies, and (c) reconstructing their environments at various levels. By bridging social, developmental, and cognitive psychology with behavioral ecology and evolutionary biology, this framework advances our understanding of human-environment interactions by (a) challenging the assumption that environmental effects are static, (b) generating precise hypotheses about psychological and behavioral patterns, enabling systematic and holistic investigation, and (c) underscoring the potential for lifelong flexibility in ecological navigation.
