Department of Psychology
Professor Lisa Henderson (Head of Psychology, University of York) and collaborators are looking to hire a full-time Research Trainee to support an exciting new research project, funded by the Huo Family Foundation. The post is available to start immediately and the project will run until 31st May 2029.
SmartSleep - Waking up to the Effects of Smartphones and Social Media
Adolescents are immersed in a smartphone-dominated world with instant access to social media. While this can offer opportunities for connection, mounting evidence points to sleep disruption, poor mental health, and declining cognition. Despite growing concern and recent policy proposals from the UK Government, we still have limited causal evidence to shape the implementation of effective policies. Existing randomised controlled trials (RCTs) face methodological challenges, and mechanistic understanding remains underdeveloped.
Our pilot work—featured in Channel 4’s Swiped—suggests that a 21-day SM/smartphone detox can improve sleep, wellbeing, and cognition in teens. Our research also points to sleep as a critical mediator between problematic smartphone use and mental health. We have now received a large grant from the Huo Family Foundation to examine the behavioural and neurophysiological pathways linking smartphone/SM use to youth mental health and cognition, focusing on sleep as a key causal mechanism.
This multimethod project will comprise a RCT with 18-21-year-olds (i.e., evaluating bedtime smartphone restriction) alongside a longitudinal study to track 11-14 year olds social media and smartphone use, as well as their sleep, mental health, cognition and social attitudes. Sleep and mental health will be measured via subjective report as well as objectively via wearables, EEG and physiological methods.
Our hope is that this research will provide policymakers with mechanistic, causal evidence and inform translational strategies to promote digital health among young people.
