Emotions and Mental Health
This study aims to examine the distinct roles of tonic (chronic) and phasic (episodic) irritability in adult depression. The study will use ecological momentary assessments to collect intensive, real-world data from adults with current or lifetime depression, capturing fluctuations in mood and behavior in participants' natural environments. Using theory-driven computational approaches, the research will identify latent parameters underlying tonic and phasic irritability. By integrating clinical, behavioral, and ecological data, this project aims to clarify how these irritability types contribute to depression trajectories and ultimately inform more targeted prediction and intervention strategies.
Participants taking part in this study will complete a baseline survey and a clinical interview. If participants meet certain threshold requirements, they will move onto a 28-day period of daily surveys. The entire study will take place virtually.

This study aims to investigate how subtle non-verbal cues—such as changes in facial expressions and speech patterns—relate to mental health symptoms, which are often difficult to detect through traditional clinical assessments or self-reports. The research will combine a virtual social communication task with a 14-day daily diary component to explore how depression interacts with everyday stressors and social experiences. In the first phase, participants will engage in Zoom-based virtual social interactions, during which facial and acoustic speech features will be extracted from screen recordings. In the second phase, participants will complete daily diaries to report on their emotional and social experiences in real-world settings. By integrating data from both Zoom interactions and daily self-reports, the study will link observed facial and speech cues to participants’ self-reported mood and social functioning. The ultimate goal is to identify behavioral markers that can support early detection of depressive symptoms, paving the way for timely interventions in diverse environments such as schools and workplaces.
Participants taking part in this study will complete a baseline survey and then schedule time slots for online recorded zoom interactions with other participants. Upon completion of 5 zoom interactions, participants will move onto a 14-day period of daily surveys. The entire study will take place virtually.
