Physical activity declines across the adult life span despite the well-established links between physical activity and health-related, psychological, cognitive, and social benefits. We contrasted the beliefs young and older adults hold about how aging affects both physical abilities and physical activity and determined whether older adults’ beliefs about physical aging relate to their engagement in physical activity. Using visual rating scales, 56 young and 49 community-dwelling older adults indicated the extent to which a typical woman or typical man aged 20–90 possesses six different physical abilities and engages in three different types of physical activity. Stereotypes of physical aging were ability- and activity-specific, and older adults endorsed more positive views than their younger peers. Stereotypical beliefs predicted older adults’ engagement in moderate-intensity activity. This study offers intriguing avenues for future research and suggests that better understanding physical aging stereotypes may contribute toward designing interventions that promote lifelong physical activity. 相似文献

The way people envision their future (self-prospection) plays a key role in the energization required to pursue desired goals. We proposed that energization is determined by time distance from the imagined future-self and the individual’s consideration of future consequences (CFC). We hypothesized that, when imagining their distant (vs. near) future-self, individuals higher on CFC (i.e., those who construe a stronger link between present and future selves), would report greater energization. Participants completed the CFC scale, imagined their distant or near future-self, and reported their energy level. Imagining distant (vs. near) future-self fostered energy among participants higher on CFC (Experiments 1–2), an effect mediated by vividness of self-representations (Experiment 2). Self-prospection has implications for current states, and specifically for felt energy. 相似文献

Despite their immense relevance, the neurocognitive mechanisms underlying real-life self-control failures (SCFs) are insufficiently understood. Whereas previous studies have shown that SCFs were associated with decreased activity in the right inferior frontal gyrus (rIFG; a region involved in cognitive control), here we consider the possibility that the reduced implementation of cognitive control in individuals with low self-control may be due to impaired performance monitoring. Following a brain-as-predictor approach, we combined experience sampling of daily SCFs with functional magnetic resonance imaging (fMRI) in a Stroop task. In our sample of 118 participants, proneness to SCF was reliably predicted by low error-related activation of a performance-monitoring network (comprising anterior mid-cingulate cortex, presupplementary motor area, and anterior insula), low posterror rIFG activation, and reduced posterror slowing. Remarkably, these neural and behavioral measures predicted variability in SCFs beyond what was predicted by self-reported trait self-control. These results suggest that real-life SCFs may result from deficient performance monitoring, leading to reduced recruitment of cognitive control after responses that conflict with superordinate goals. 相似文献

Alcohol intoxication is implicated in approximately half of all violent crimes. Over the past several decades, numerous theories have been proposed to account for the influence of alcohol on aggression. Nearly all of these theories imply that altered functioning in the prefrontal cortex is a proximal cause. In the present functional magnetic resonance imaging (fMRI) experiment, 50 healthy young men consumed either a low dose of alcohol or a placebo and completed an aggression paradigm against provocative and nonprovocative opponents. Provocation did not affect neural responses. However, relative to sober participants, during acts of aggression, intoxicated participants showed decreased activity in the prefrontal cortex, caudate, and ventral striatum, but heightened activation in the hippocampus. Among intoxicated participants, but not among sober participants, aggressive behavior was positively correlated with activation in the medial and dorsolateral prefrontal cortex. These results support theories that posit a role for prefrontal cortical dysfunction as an important factor in intoxicated aggression. 相似文献

We used eye tracking to quantify the extent to which combinations of salient contrasts (orientation, luminance, and movement) influence a central salience map that guides eye movements. We found that luminance combined additively with orientation and movement, suggesting that the salience system processes luminance somewhat independently of the two other features. On the other hand, orientation and movement together influenced salience underadditively, suggesting that these two features are processed nonindependently. This pattern of results suggests that the visual system does not sum sources of salience linearly, but treats some sources of salience as redundant.

The flow experience can be an important precursor to high levels of creativity and innovation. Prior work has identified and conceptualized the key elements of the flow experience in cocreative activities as individual flow corridor, individual flow feeling, and group flow. Surprisingly, the flow experience is underrepresented in theory and practice of design thinking. In this empirical study, the flow experience at the individual and group level was investigated in a 1-day design thinking exercise. The findings from partial least squares (PLS) modeling of 230 observations confirm previously untested conjectures that (a) the elements of individual and group flow experience were prevalent and highly correlated in the design thinking activities and (b) the nature of the design thinking task had an impact on the flow experience. Finally, results confirm that Lego Serious Play skills-building as a creative warm-up had a positive effect on 2 of the 3 flow experience elements: individual flow feeling and individual flow corridor. 相似文献

As the result of secularization and adaption of mindfulness practices from Buddhism, elements specific to culture and religion have been removed, now drawing criticism that mindfulness training has lost its original ethical characteristics. This article argues that the lack of formal coverage of morality in mindfulness‐based programs does not imply that morality plays no part, and that participants independently contextualize their mindfulness practice by drawing on their own sense of morality. Therefore, awareness of the role of morality in mindfulness practice is important for counselors, who can assist their clients with integrating their mindfulness practice with their own worldviews and ethical frameworks. 相似文献

One widely accepted empirical regularity in free recall holds that when people successively transition from report of one
list item to another, they prefer transitions across short lags (e.g., by reporting items from adjacent serial positions)
to transitions involving large lags. This regularity has provided crucial support for the temporal context model (TCM), a
model of the evolution of temporal context in episodic memory (Howard & Kahana, 2002a). We report a reanalysis of 14 data
sets that shows that, contrary to the presumed preference for short lags, people often produce transitions with larger lags
during recall. We show that these data cannot be accommodated by the TCM. We furthermore show that existing applications of
the model have, for mathematical convenience, introduced assumptions that have circumvented its core principle of context
evolution. When we instantiated the TCM as it was actually described, with a gradually evolving context, we found that its
behavior qualitatively departed from that of the version currently implemented, but that the model was still unable to capture
the nature of transitions in free recall. We conclude that the TCM requires further modification and development before it
can explain the data that constitute its main source of support. Supplementary materials relevant to this article can be downloaded
