Science of Adult Relationships Laboratory
Exploring relationship dynamics from young adulthood to later life stages
How our research enhances the understanding of adult relationships
The Science of Adult Relationships Laboratory investigates the processes shaping relationships throughout adulthood, from young adulthood to later life. By integrating key social psychology and personality theories, we examine how life events, transitions and social issues influence relationship dynamics.
Our research provides practical insights for academics, therapists and the public, bridging the gap between science and real-world application. Using diverse approaches, such as attachment theory, interdependence theory and stress-coping models, we explore how relationships evolve and impact wellbeing.
Our research areas
We investigate key relationship dynamics, offering insights into their function and impact across life stages, with applications in both science and practice.
Evaluating relationship partners
This research explores how perceptions of romantic partners based on personal ideals shape thoughts, feelings and behaviours. We focus on identifying predictors of whether partners meet or fall short of these ideals and the resulting impact.
The dark side of romantic relationships
We study harmful behaviours in relationships, such as sexual coercion and interpersonal dehumanisation, focusing on subtle, everyday expressions. Our interest lies in understanding the factors influencing whether individuals become perpetrators or victims.
The impact of life transitions
This research examines how major life transitions affect romantic, familial and peer relationships. We look at both the negative outcomes, such as relationship disruptions, and the protective factors that help relationships thrive during transitions.
Chronic illness and ageing families
We explore how couples and families cope with the challenges of chronic illness and caring for ageing parents, focusing on support dynamics and the mental health impact of caregiving. This research has been funded by beyondblue and the Australian Research Council.
The interplay between behavioural systems
This research investigates how attachment, caregiving and sexual systems work together to influence relationship functioning, as well as how reward and punishment systems shape relationship behaviours and responses to stress.
Shape the future of relationships
Join our research efforts to better understand relationships and create meaningful solutions for couples and families. Access key research resources and collaborate with our team to shape the future of relationship science.
What really matters is that you don't see your partner or relationship as this fixed entity that cannot change over time. All relationships can change for the better with work and nurturing.
Director, Science of Adult Relationships Laboratory
Our researchers
The Science of Adult Relationships Laboratory is led by a team of experts dedicated to advancing the understanding of relationship dynamics.
Professor Gery Karantzas is the director of the Science of Adult Relationships Laboratory and professor in psychology at Deakin. He is one of Australia’s leading relationship scientists. With over 90 publications and more than $5 million in research funding, his work primarily explores attachment theory, relationship evaluation and stress-coping mechanisms.
Dr Emma Marshall is the deputy director of the Science of Adult Relationships Laboratory and lecturer in psychology at Deakin. Her research focuses on the relational foundations of physical and mental health across the lifespan. Specialising in stress, trauma and life transitions, she uses surveys, diaries and behavioural observations to identify resilience mechanisms.
Featured projects
Our researchers are investigating key areas of relationship dynamics, offering new insights into how we connect and interact with others.
Couple CLASH: exploring relationship dynamics
This study examines how life experiences, stress, attitudes and personalities influence romantic relationships. By tracking couples over time, the research aims to uncover factors that affect relationship dynamics and inform future clinical interventions and policy decisions.
Understanding pornography use in relationships
This research explores the role of pornography in romantic relationships, examining factors like frequency, content and context of use. The study has led to the development of a new measure of porn use in relationships, offering valuable insights for future research and clinical applications.
