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,

Social cognitive theory adopts an agentic perspective in which individuals are
producers of experiences and shapers of events. Among the mechanisms of human
agency, none is more focal or pervading than the belief of personal efficacy.
This core belief is the foundation of human agency. Unless people believe that
they can produce desired effects and forestall undesired ones by their actions,
they h... hiện toàn bộ
The most unexpected and intriguing result from functional brain imaging studies
of cognitive aging is evidence for age-related overactivation: greater
activation in older adults than in younger adults, even when performance is
age-equivalent. Here we examine the hypothesis that age-related overactivation
is compensatory and discuss the compensation-related utilization of neural
circuits hypothesis... hiện toàn bộ
Researchers have increasingly turned their attention from younger individuals
who hold age stereotypes to older individuals who are targeted by these
stereotypes. The refocused research has shown that positive and negative age
stereotypes held by older individuals can have beneficial and detrimental
effects, respectively, on a variety of cognitive and physical outcomes. Drawing
on these experiment... hiện toàn bộ
Trying to understand why adolescents and young adults take more risks than
younger or older individuals do has challenged psychologists for decades.
Adolescents' inclination to engage in risky behavior does not appear to be due
to irrationality, delusions of invulnerability, or ignorance. This paper
presents a perspective on adolescent risk taking grounded in developmental
neuroscience. According ... hiện toàn bộ
Like many other animals, human beings engage in behavioral defenses against
infectious pathogens. The behavioral immune system consists of a suite of
psychological mechanisms that (a) detect cues connoting the presence of
infectious pathogens in the immediate environment, (b) trigger disease-relevant
emotional and cognitive responses, and thus (c) facilitate behavioral avoidance
of pathogen infect... hiện toàn bộ
Working memory storage capacity is important because cognitive tasks can be
completed only with sufficient ability to hold information as it is processed.
The ability to repeat information depends on task demands but can be
distinguished from a more constant, underlying mechanism: a central memory store
limited to 3 to 5 meaningful items for young adults. I discuss why this central
limit is import... hiện toàn bộ
Theory and research suggest that people can increase their happiness through
simple intentional positive activities, such as expressing gratitude or
practicing kindness. Investigators have recently begun to study the optimal
conditions under which positive activities increase happiness and the mechanisms
by which these effects work. According to our positive-activity model, features
of positive ac... hiện toàn bộ
