What is the Origin of Intrinsic Motivation Physiology?

This concept bridges self-determination theory in psychology with neuroendocrinology, seeking to identify the internal physiological drivers of autonomous action and persistence. It contrasts sharply with extrinsically motivated behavior, which relies on external reinforcement.

What is the Mechanism of Intrinsic Motivation Physiology?

Intrinsic motivation is closely linked to the basal ganglia and the mesolimbic dopamine pathway, where the successful completion of a task, or the feeling of mastery, directly stimulates the release of neurotransmitters that generate a positive internal state. This powerful, self-reinforcing loop, often involving endogenous opioids and dopamine, ensures the persistence of the beneficial behavior without the need for continuous external prompting.

Intrinsic Motivation Physiology

Meaning

The underlying neurobiological and hormonal processes that drive an individual to engage in health-promoting activities purely for the inherent satisfaction, enjoyment, or sense of competence derived from the activity itself, rather than for external rewards or pressures. This intrinsic drive is the most powerful and sustainable foundation for long-term health behavior. It represents true behavioral autonomy.
