EXPERIENTIAL DIVERSITY: NEW MEASUREMENT APPROACHES AND NEW INSIGHTS INTO DAILY SLEEP AND COGNITION - Symposium

Upload by acoobca

Research on experiential diversity has expanded, yet most work relies on between-person comparisons of individuals with higher versus lower diversity. Intensive longitudinal data now enables quantifying daily experiential diversity and testing links to day-to-day health outcomes. This symposium aligns methodological progress with theory emphasizing sociohistorical context, proposing new ways to measure daily experiential diversity beyond standard entropy and diversity indices. Across five presentations, nightly sleep quantity and quality, working memory, objective cognition, emotional support diversity, and sequence-based activity diversity are examined across adults, with an integrative discussant synthesis of implications for health and well-being across the life span.

SESSION 4050 (SYMPOSIUM) Abstract citation ID: igaf122.1601 EXPERIENTIAL DIVERSITY: NEW MEASUREMENT APPROACHES AND NEW INSIGHTS INTO DAILY SLEEP AND COGNITION Chair: Soomi Lee Co-Chair: Rachel Koffer Discussant: Martin Sliwinski Research on experiential diversity (i.e., variety) has burgeoned in recent years, yet most studies remain at the between-person analyses (e.g., comparing individuals with greater activity diversity to those with lower activity diversity). With the rise of intensive longitudinal data, researchers now have the opportunity to quantify daily experiential diversity and examine its associations with daily health outcomes. These methodological advancements coincide with theoretical advancements highlighting the importance of sociohistorical context, and invite new approaches to assessing daily experiential diversity beyond the between-person entropy and other diversity indices. This symposium brings together five presentations to understand the dynamics among daily activity diversity, nightly sleep, and ambulatory cognition, while also exploring emerging domains and innovative methods for assessing daily experiential diversity. Lee presents the associations of nightly sleep quantity and quality with day-level activity diversity, including age-related differences in these associations. Drewelies examines the associations between daily subjective working memory and within-and between-person activity diversity in older adults. Bielak uses 14-day momentary objective cognitive tests (4 times/day) and their associations with activity variety (a composite sum) at the between-person and within-person levels. Clancy focuses on a new domain of experiential diversity, diversity in emotional support, and examinesits sociohistorical, and age-related trends. Koffer proposes a sequence analysis approach to daily activity diversity, showing how daily sequences are associated with entropy, age, and sleep as a daily health indicator. The Discussant, Sliwinski, will integrate these findings and discuss the implications of experiential diversity for health and well-being across the adult life span.

FAQs

Why is experiential diversity measurement moving beyond between-person analyses?

Intensive longitudinal data allows researchers to quantify experiential diversity on a daily basis and evaluate its associations with daily health outcomes, rather than only comparing individuals across groups.

Which aspects of daily cognition and sleep are addressed in the symposium?

Presentations examine how nightly sleep quantity and quality relate to day-level activity diversity, how daily subjective working memory and ambulatory objective cognition relate to activity variety, and how these links vary by age.

What new methodological ideas are proposed for assessing daily experiential diversity?

Speakers discuss approaches that extend beyond between-person entropy and other diversity indices, including new domains such as emotional support diversity and a sequence analysis method for daily activity diversity and its relation to entropy, age, and sleep.
