Self-Control Relies on Glucose as a Limited Energy Source: Willpower Is More Than a Metaphor
[Journal of Personality and Social Psychology, 2007, Vol. 92, No. 2, 325–336]
Abstract:
The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests
of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of
social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an
interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels
of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control
task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but
consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of
glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels,
thereby impairing subsequent attempts at self-control.

The pursuit of meaningfulness in life.

Abstract
- Human beings begin life as animals and remain tied throughout life to natural cycles of birth and death, eating and sleeping, reproduction, danger and safety, and more. Yet to this natural dimension of human life must be added a cultural one. Humans use their thinking capacity to transcend their immediate environment and their natural urges and responses. Thinking usually involves meaning, as in the use of language, symbols, and connections between concepts. The authors discuss the pursuit of the meaningfulness in life. The aim of positive psychology is to catalyze change in psychology from a preoccupation only with repairing the worst things in life to also building the best qualities in life. The field of positive psychology at the subjective level is about positive subjective experience: well-being and satisfaction (past); flow, joy, the sensual pleasures, and happiness (present); and constructive cognitions about the future--optimism, hope, and faith.
