Self-control - As A Limited Resource

As A Limited Resource

For more details see Ego depletion

Research by Roy Baumeister and colleagues has shown that people's ability to exert self-control depends on a strength-like resource that diminishes after use.

After participants performed a task requiring self-control, they were less able to exert self-control, even in entirely different areas; this result was replicated in over a hundred experiments.

There is also evidence that training people to accept the time delay before receiving a reward similarly enhances people's self-control. Donal Logue (1984) used a fading procedure in which participants were initially presented with a choice between two different rewards - a small one and a big one - which could be received after the same (large) time delay. On subsequent presentations of the two rewards, the time delay for the small reward was gradually reduced. The results showed that as the time delay for the small reward decreased, participants tended to choose the big reward more often than the small reward. Thus, Logue was able to condition participants to accept a large time delay in order to receive a big reward, rather than to choose not to wait in order to receive a small but immediate reward. Not only can people be trained to accept long time delays, but people's perception of the delay itself can be modified. For instance, Mischel and Ebbessen (1970) showed that a distracting entertaining task can lead people to perceive the time delay as shorter than they typically perceive it.

In sum, although there is empirical evidence that self-control is a limited mental resource, a number of studies support the notion that self-control is nevertheless a resource that can be increased through suitable "exercise".

Famous quotes containing the words limited and/or resource:

    Misfortunes leave wounds which bleed drop by drop even in sleep; thus little by little they train man by force and dispose him to wisdom in spite of himself. Man must learn to think of himself as a limited and dependent being; and only suffering teaches him this.
    Simone Weil (1909–1943)

    Your kind doesn’t just kill men. You murder their spirits, you strangle their last breath of hope and freedom, so that you, the chosen few, can rule your slaves in ease and luxury. You’re a sadist just like the others, Heiser, with no resource but violence and no feeling but fear, the kind you’re feeling now. You’re drowning, Heiser, drowning in the ocean of blood around this barren little island you call the New Order.
    Curtis Siodmak (1902–1988)
