Selfactivity

Self-activity is a concept used in multiple disciplines to describe the capacity of a system to initiate, regulate, or sustain its own actions, rather than acting solely in response to external input. In philosophy and cognitive science, self-activity refers to the exercise of agency and intentionality by a subject, encompassing voluntary goal-directed behavior, self-determination, and the way inner states influence outward action. In developmental and educational contexts, self-activity is emphasized as self-directed or autonomous engagement: learners identify objectives, plan actions, monitor progress, and reflect on outcomes.

In biology and systems theory, self-activity is discussed in terms of autopoiesis or self-organization, where a living system maintains its organization and continuity by processes within itself. This notion contrasts with passive or externally driven processes. In artificial intelligence and robotics, self-activity relates to agents that exhibit intrinsic motivation or curiosity, enabling exploratory behavior and goal formation from within rather than being strictly guided by external tasks.

Measurement and critique: The term is sometimes used descriptively rather than as a precise technical term; researchers differ on its exact scope and how to operationalize it. Debates address the boundary between automatic, habitual actions and genuine self-initiated action, and the degree to which self-activity implies conscious awareness.
