Current Research and Scholarly Interests


I research age-related changes in the way people prefer to use their time and decide how to do so. Using a mixture of observational and experimental data, I focus primarily on the relationship between the perception of future-time as abundant and open-ended (vs. scarce and limited) and preference for activities that hold future-oriented and emotionally meaningful benefits.

  • Age-related emotional advantages in encountering novel situation in daily life. Psychology and aging Chu, L., Shavit, Y. Z., Ram, N., Carstensen, L. L. 2024; 39 (2): 113-125

    Abstract

    People encounter novel situations throughout their lives that contribute to the acquisition of knowledge and experience. However, novelty can be misaligned with goals and motivation in later adulthood according to socioemotional selectivity theory. This study investigated age differences in emotional reactions associated with novel experiences. Multilevel structural equation models were used to analyze experience-sampling data obtained from an adult sample of 375 participants aged 18-94 years who reported their current situation and momentary emotional experience five times per day for 7 days. On occasions where situations were rated as more novel, people reported reduced positive and increased negative emotion. Those who had more overall exposure to novel situations tended to have more negative emotional experiences in general. Contrary to our hypothesis, there were age differences in individuals' negative emotional reactivity to situations that are perceived as more novel, such that novel situations were reported as less negative among older adults. By applying theoretical understanding of age differences in motivation and well-being in adulthood, our findings illuminate aspects of situations that elicit negative emotions. Findings highlight age-related benefits in emotional well-being, consistent with socioemotional selectivity theory postulates, and further implies that older adults may not be novelty averse.

  • Age and Time Horizons Are Associated With Preferences for Helping Colleagues. Work, aging and retirement Shavit, Y. Z., Chi, K., Carstensen, L. L. 2023; 9 (3): 280-290

    Abstract

    The present study examined the causal role of time horizons in age differences in worker motivation. Based on socioemotional selectivity theory (SST), we hypothesized that under unspecified time horizons, older workers prefer to engage in emotionally meaningful work activities more so than younger workers. We further hypothesized that when time horizons at work are expanded or limited, age differences are eliminated. We recruited a sample of employees (N = 555) and randomly assigned them to one of three experimental conditions: a no-instruction condition in which time horizons were not specified, an expanded time horizons condition, or a limited horizons condition. We asked participants to choose from among three options for work-related activities: Helping a colleague or a friend, working on a career-advancing project, or working on a project which may take the company in a new direction. Consistent with SST postulates, we found that age was associated with preferences for helping colleagues in the unspecified horizons condition, and that age differences were eliminated when time horizons were extended or limited. As hypothesized, expanding time horizons reduced employees' likelihood of choosing to help colleagues. Contrary to our hypothesis, limiting time horizons also reduced the likelihood of choosing to help colleagues. Alternative explanations are considered. Findings suggest that age differences in worker motivation are shaped by time horizons and that modification of time horizons can alter work preferences.

  • Positive Relationships have Shades of Gray: Age is Associated with More Complex Perceptions of Relationship Quality During the COVID-19 Lockdown. Journal of adult development Shavit, Y. Z., Estlein, R., Elran-Barak, R., Segel-Karpas, D. 2022: 1-12

    Abstract

    Drawing on socioemotional selectivity theory, we examined the effect of COVID-19 lockdowns on perceptions of romantic relationships quality among older, compared to younger, adults. During the first lockdown in Israel which involved strict restrictions on movement and association with others, 280 adults aged 25-81 reported positive and negative qualities of their romantic relationship. Of these, 105 participants completed the survey again once lockdown restrictions were lifted. Contrary to our hypotheses, no evidence for age differences in the effect of the lockdown on positive or negative perceptions of relationship quality was detected. In addition, the lockdown did not influence participants' positive and negative perceptions of their romantic partners. However, we did find that, whereas people of all ages represent positive and negative qualities of their romantic partners as separate constructs, the negative association between the two is weaker for older adults compared to younger adults during (but not after) the lockdown. This finding suggests that in stressful times, older adults are better able to avoid negative perceptions clouding positive perceptions and see positive aspects of relationships with romantic partners in the face of negative ones. Findings extend evidence for age associations with complex emotional experiences to emotional aspects of interpersonal relationships. Findings enrich the theoretical understanding of age-related advantages in emotional well-being and may inform potential interventions for improving emotional health and well-being during times of crisis.Supplementary Information: The online version contains supplementary material available at 10.1007/s10804-022-09431-6.

    Abstract

    The COVID-19 pandemic is creating unprecedented, sustained, and unavoidable stress for the entire population, and older people are facing particularly heightened risk of contracting the virus and suffering severe complications, including death. The present study was conducted when the pandemic was spreading exponentially in the United States. To address important theoretical questions about age differences in emotional experience in times of crisis, we surveyed a representative sample of 945 Americans between the ages of 18 and 76 years and assessed the frequency and intensity of a range of positive and negative emotions. We also assessed perceived risk of contagion and complications from the virus, as well as personality, health, and demographic characteristics. Age was associated with relatively greater emotional well-being both when analyses did and did not control for perceived risk and other covariates. The present findings extend previous research about age and emotion by demonstrating that older adults' relatively better emotional well-being persists even in the face of prolonged stress.

  • Does Becoming A Volunteer Attenuate Loneliness Among Recently Widowed Older Adults? JOURNALS OF GERONTOLOGY SERIES B-PSYCHOLOGICAL SCIENCES AND SOCIAL SCIENCES Carr, D. C., Kail, B., Matz-Costa, C., Shavit, Y. Z. 2018; 73 (3): 501–10

    Abstract

    Loneliness is a significant public health concern, particularly for those who have lost a spouse through widowhood. This study examines whether becoming a volunteer at the time of widowhood is associated with reduction of these risks.A pooled sample of 5,882 married adults age 51+, drawn from the 2006-2014 waves of the Health and Retirement Study, was used to estimate regression models of the relationship between becoming widowed (relative to staying continuously married) and loneliness, and whether the associated loneliness of having lost a spouse is moderated by starting to volunteer (<2 hr, 2+ hr/week).Our results show that for those who become widowed, loneliness is significantly higher than those who stay continuously married. However, starting to volunteer 2+ hr per week is related to attenuated loneliness among the widowed such that widows who volunteer at that intensity have levels of loneliness similar to those of continuously married individuals volunteering at the same intensity.This study suggests higher intensity volunteering may be a particularly important pathway for alleviating loneliness among older adults who have recently become widowed. Results are discussed in light of theory, future research, and potential interventions.
