Trajectories of Being: How Affordances Shape Identity and Behavior across Time

Abstract This paper introduces the Dynamic Affordance Trajectory Framework (DATF), a multiscalar approach to understanding human behavior and identity formation. It integrates short-term perception-action cycles, medium-term adaptation, and long-term sociocultural influences, emphasizing the dynamic relationship between agents and their environments in three scales: micro, meso and macro. Central to the framework is the concept of affordance trajectories – the evolving opportunities for action that unfold over time. The DATF also incorporates affective niches and ontogenetic niche trajectories, tracing environmental influences on development. The framework highlights how cognitive agency is distributed, emphasizing the interdependence of individual development. This synergy enhances understanding of individual adaptation within social and ecological networks. By showcasing key concepts such as learning music and performing as a worker in a world of changing conditions, the DATF demonstrates its ability to provide a richer understanding of human experiences. By applying the DATF to education, therapy, and community planning, this framework emphasizes the ability for human understanding. This framework contextualizes behavior within evolving landscapes of opportunity and constraint, and calls for future research to explore its applications.
