Selvkontrol er afgørende for succes og afhænger af en begrænset ressource. Ligesom en muskel svækkes ved brug, fører selvkontrol til kortvarig udmattelse. Studier bekræfter denne model på tværs af adfærdsmæssige domæner. Motivation og rammesætning kan midlertidigt modvirke udmattelsen, hvor blodglukose spiller en vigtig rolle.

The Strength Model of Self-Control.

Hele abstrakt på originalsprog:
Self-control is a central function of the self and an important key to success in life. The exertion of self-control appears to depend on a limited resource. Just as a muscle gets tired from exertion, acts of self-control cause short-term impairments (ego depletion) in subsequent self-control, even on unrelated tasks. Research has supported the strength model in the domains of eating, drinking, spending, sexuality, intelligent thought, making choices, and interpersonal behavior. Motivational or framing factors can temporarily block the deleterious effects of being in a state of ego depletion. Blood glucose is an important component of the energy.
