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/...
findanexpert.unimelb.edu.au
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>

Overall, the findings highlight the complexity of implementing mobile phone policies in schools and point to a need for greater consistency in both policy and digital safeguarding practice. 3/3

Emma Sullivan @emmacsullivan.bsky.social · 12/03/2026
We found that schools with policies were more likely to report incidents, suggesting policy presence may shape reporting. But wide variation in policy content and inconsistent “ban” terminology may undermine effective safeguarding. 2/3

Moving forwards, future studies should employ validated measures and move beyond frequency-based metrics of social media to explore how content, patterns of problematic use, and the timing of use all influence sleep longitudinally.
100
Emma Sullivan @emmacsullivan.bsky.social · 18/12/2025
There was a heavy reliance on self-reports and non-validated measures of social media use and sleep, which restricts our conclusions.
100
Emma Sullivan @emmacsullivan.bsky.social · 18/12/2025
The strongest negative effects were seen for problematic social media use and excessive use around bedtime, and this tended to manifest in later bedtimes and delayed sleep onset.

Emma Sullivan @emmacsullivan.bsky.social · 18/12/2025
We found overall a negative impact of social media on sleep in young people, however this association was nuanced and complex.

Overall, these findings suggest that sleep quality and adaptive emotion regulation hold independent roles in reducing emotional inertia. Both are key to emotional wellbeing, but don't rely on each other.

Emma Sullivan @emmacsullivan.bsky.social · 06/01/2025
Interestingly, the association between greater adaptive ER strategy use and lower NA inertia was observed regardless of participants' sleep quality.
100
Emma Sullivan @emmacsullivan.bsky.social · 06/01/2025
We found that better sleep quality was linked to lower NA inertia. In other words, good sleep helps reduce the persistence of negative affect over time.
100
Emma Sullivan @emmacsullivan.bsky.social · 06/01/2025
In this online study (N = 245), we used a validated film clip task to index NA inertia. Sleep quality and use of adaptive emotion regulation strategies were measured using questionnaires.

Emma Sullivan @emmacsullivan.bsky.social · 06/01/2025
We know that good sleep and using adaptive emotion regulation strategies can help reduce negative affect persistence (NA inertia). But do they work in concert to reduce NA inertia?
100
Emma Sullivan @emmacsullivan.bsky.social · 06/01/2025
Emotional inertia- when negative feelings persist over time- has been linked to poorer wellbeing. But we know little about the mechanisms underlying this link.
