Research in the Emotion Lab is broadly concerned with understanding the nature and function of human emotion, using a range of tools—standard laboratory experiments, implicit and explicit behavioral measures, and ambulatory assessments and psychophysiology. Current topics of interest include:
Positive Emotions and Health
Theory and empirical research suggest that the experience of high positive affect conveys many desirable life outcomes, the summative effects of which may be delaying the onset of disease and extending healthy functioning.
We are particularly interested in the pathways linking positive emotions to quality living and health morbidities in both healthy and clinical populations. Ongoing work in the lab explores the role of positive affect in both resilience-enhancing and vulnerability-inducing health outcomes.
Individual Differences in Emotional Complexity
There is tremendous variety in the emotional states that constitute everyday life. Some people have emotional experiences that are wide in range and well differentiated, while others experience emotions in a highly diffuse and global manner.
Work on this front is just beginning. We have been interested in individual differences, especially those that have relevance for differentiation of emotional experience over time. In particular, our lab has examined individual differences factors (e.g., neuroticism, cognitive simplicity, resilience) that account for variability in the structure of emotions over time and between persons. More recent investigations have explored how the breadth and relative abundance of emotions that individuals experience is associated with mental and physical health.
Emotions and Daily Experience
Emotions fluctuate over time and are responsive to everyday events. Three broad questions drive this work. First, are level and stability of emotion distinct dimensions along which individuals can be characterized? Second, is emotion intraindividual variability a meaningful predictor of mental and physical health? And how do early environments promote the development of conditional or contingent emotional reactions to everyday experiences.
Current projects focus on emotional reactivity and psychobiological processes relevant to health, including inflammatory, neuroendocrine, and restorative processes.
