Happiness unpacked: positive emotions increase life satisfaction by building resilience.

Abstract: Happiness—a composite of life satisfaction, coping resources, and positive emotions—predicts desirable life outcomes in many domains. The broaden-and-build theory suggests that this is because positive emotions help people build lasting resources. To test this hypothesis, the authors measured emotions daily for 1 month in a sample of students (N 86) and assessed life satisfaction and trait resilience at the beginning and end of the month. Positive emotions predicted increases in both resilience and life satisfaction. Negative emotions had weak or null effects and did not interfere with the benefits of positive emotions. Positive emotions also mediated the relation between baseline and final resilience, but life satisfaction did not. This suggests that it is in-the-moment positive emotions, and not more general positive evaluations of one’s life, that form the link between happiness and desirable life outcomes. Change in resilience mediated the relation between positive emotions and increased life satisfaction, suggesting that happy people become more satisfied not simply because they feel better but because they develop resources for living well.

At the Intersection of Emotion and Cognition Aging and the Positivity Effect

Abstract: Divergent trajectories characterize the aging mind: Processing capacity declines, while judgment, knowledge, and emotion regulation are relatively spared. We maintain that these different developmental trajectories have implications for emotion–cognition interactions. Following an overview of our theoretical position, we review empirical studies indicating that (a) older adults evidence superior cognitive performance for emotional relative to non-emotional information, (b) age differences are most evident when the emotional content is positively as opposed to negatively valenced, and (c) differences can be accounted for by changes in motivation posited in socioemotional selectivity theory.

Emotional category data on images from the International Affective Picture System.

Abstract: The International Affective Picture System (IAPS) is widely used in studies of emotion and has been characterized primarily along the dimensions of valence, arousal, and dominance. Even though research has shown that the IAPS is useful in the study of discrete emotions, the categorical structure of the IAPS has not been characterized thoroughly. The purpose of the present project was to collect descriptive emotional category data on subsets of the IAPS in an effort to identify images that elicit one discrete emotion more than others. These data reveal multiple emotional categories for the images and indicate that this image set has great potential in the investigation of discrete emotions. This article makes these data available to researchers with such interests. Data for all the pictures are archived at www .psychonomic.org/archive/.

Meta-analysis of the age-related positivity effect: Age differences in preferences for positive over negative information.

Abstract: In contrast to long-held axioms of old age as a time of “doom and gloom,” mounting evidence indicates an age-related positivity effect in attention and memory. However, several studies report inconsistent findings that raise critical questions about the effect’s reliability, robustness, and potential moderators. To address these questions, we conducted a systematic meta-analysis of 100 empirical studies of the positivity effect (N!7,129). Results indicate that the positivity effect is reliable and moderated by theoretically implicated methodological and sample characteristics. The positivity effect is larger in studies that do not constrain (vs. constrain) cognitive processing—reflecting older adults’ natural information processing preferences—and in studies incorporating wider (vs. narrower) age comparisons. Analyses indicated that older adults show a significant information processing bias toward positive versus negative information, whereas younger adults show the opposite pattern. We discuss implications of these findings for theoretical perspectives on emotion‐cognition interactions across the adult life span and suggest future research directions.

A Warm Heart and a Clear Head The Contingent Effects of Weather on Mood and Cognition

Abstract: Prior studies on the association between weather and psychological changes have produced mixed results. In part, this inconsistency may be because weather's psychological effects are moderated by two important factors: the season and time spent outside. In two correlational studies and an experiment manipulating participants' time outdoors (total N = 605), pleasant weather (higher temperature or barometric pressure) was related to higher mood, better memory, and "broadened" cognitive style during the spring as time spent outside increased. The same relationships between mood and weather were not observed during other times of year, and indeed hotter weather was associated with lower mood in the summer. These results are consistent with findings on seasonal affective disorder, and suggest that pleasant weather improves mood and broadens cognition in the spring because people have been deprived of such weather during the winter.

The Adaptive Brain: Aging and Neurocognitive Scaffolding

Abstract: There are declines with age in speed of processing, working memory, inhibitory function, and long-term memory, as well as decreases in brain structure size and white matter integrity. In the face of these decreases, functional imaging studies have demonstrated, somewhat surprisingly, reliable increases in prefrontal activation. To account for these joint phenomena, we propose the scaffolding theory of aging and cognition (STAC). STAC provides an integrative view of the aging mind, suggesting that pervasive increased frontal activation with age is a marker of an adaptive brain that engages in compensatory scaffolding in response to the challenges posed by declining neural structures and function. Scaffolding is a normal process present across the lifespan that involves use and development of complementary, alternative neural circuits to achieve a particular cognitive goal. Scaffolding is protective of cognitive function in the aging brain, and available evidence suggests that the ability to use this mechanism is strengthened by cognitive engagement, exercise, and low levels of default network engagement.

Insights into the ageing mind: a view from cognitive neuroscience.

Abstract: As we grow older, we may grow wiser, but we can also experience memory loss and cognitive slowing that can interfere with our daily routines. The cognitive neuroscience of human ageing, which relies largely on neuroimaging techniques, relates these cognitive changes to their neural substrates, including structural and functional changes in the prefrontal cortex, medial temporal lobe regions and white matter tracts. Much remains unknown about how normal ageing affects the neural basis of cognition, but recent research on individual differences in the trajectory of ageing effects is helping to distinguish normal from pathological origins of age-related cognitive changes.

Open Hearts Build Lives: Positive Emotions, Induced Through Loving-Kindness Meditation, Build Consequential Personal Resources

Abstract: B. L. Fredrickson's (1998, 2001) broaden-and-build theory of positive emotions asserts that people's daily experiences of positive emotions compound over time to build a variety of consequential personal resources. The authors tested this build hypothesis in a field experiment with working adults (n = 139), half of whom were randomly-assigned to begin a practice of loving-kindness meditation. Results showed that this meditation practice produced increases over time in daily experiences of positive emotions, which, in turn, produced increases in a wide range of personal resources (e.g., increased mindfulness, purpose in life, social support, decreased illness symptoms). In turn, these increments in personal resources predicted increased life satisfaction and reduced depressive symptoms. Discussion centers on how positive emotions are the mechanism of change for the type of mind-training practice studied here and how loving-kindness meditation is an intervention strategy that produces positive emotions in a way that outpaces the hedonic treadmill effect.
