Was great to contribute to this New Scientist article about our new pre-print on sleep deprivation and ambiguous threat from my PhD (a very long time in the making!): www.biorxiv.org/content/10.6...

Sleep deprivation impairs emotional adaptation to prolonged and ambiguous threat
Sleep problems are strongly linked to anxiety, but the psychological mechanisms underpinning this relationship are poorly understood. In this pre-registered study, we combined virtual reality, psychop...

We're (@katiegreenaway.bsky.social) recruiting a new PhD student to work on interpersonal emotion regulation in everyday life. The position is for a joint PhD program between the University of Melbourne and KU Leuven. Please share! findanexpert.unimelb.edu.au/opportunity/...

Realigning interpersonal regulation in everyday life : Find an Expert : The University of Melbourne
<p> Our societies are becoming more socially disconnected. To address this problem, we need to understand how social connection is created. One powerful method to build social connections is interpersonal emotion regulation, which involves the processes through which people seek and offer emotional support. However, people report providing more emotional support than they receive, suggesting that the provision of emotional support is often unnoticed or unsuccessful. This project aims to understand and reduce this misalignment between the perception and provision of emotional support in everyday life. To do this, we investigate these processes in romantic couples, using new dyadic experience-sampling tools to capture both partners’ perspectives in real time. The project consists of three work packages. Work Package 1 will determine whether perception-provision misalignment is most frequently driven by the receiver or the provider, and which type of misalignment is more consequential for emotional and relational outcomes. Work Package 2 will identify the antecedents of perception-provision misalignment, establishing contextual, individual, and couple-level factors to see who is more at risk when. Finally, Work Package 3 will test a brief intervention to reduce misalignment between perception and provision of support. In determining when and why there are gaps between perceived and provided interpersonal emotion regulation, the project will generate practical methods to strengthen everyday social connection. </p>

I'm excited to share that the second study of my PhD, exploring the links between emotion regulation, sleep quality, and emotional inertia, has been published in Cognition & Emotion! www.tandfonline.com/doi/full/10....

Emotional inertia is independently associated with cognitive emotion regulation strategies and sleep quality*
Emotional inertia (i.e. the tendency for emotions to persist over time) is robustly associated with lower wellbeing. Yet, we know little about the mechanisms underlying this relationship. Good qual...
