Staff Group(s)


Dr Nadja Heym is a Senior Lecturer in Psychology. She is a module leader of Psychopathology (year 3), Personality, Personality Disorder & Violence (year 3) and Individual Differences (MSc/PGDip), as well as for the psychometric sequence in Research Methods 2 (year 2). She also contributes to teaching in Studies in Legal Psychology and Applied Psychology of Digital Technology (Cyberpsychology MSc). In addition, she supervises undergraduate and postgraduate research projects in individual differences, psychopathology and cyberpsychology.

Dr Nadja Heym is co-chair of the Affect, Personality and the Embodied Brain (APE) research group at NTU and the wider APE international network, which meets regularly for research seminars and organises an annual conference (APE2020). She is also a member of the Aggression & Bullying and Cyberpsychology research groups.

Career overview

Dr Heym was awarded her PhD in 2009 from the University of Nottingham, and was employed there as a Research Coordinator on the IMAGEN project in the Brain and Body Centre. She subsequently also lectured there Individual Differences, Social and Developmental Psychology in the School of Psychology. Dr Heym joined NTU in April 2014.

Research areas

Dr Heym's main research interests are within the area of individual differences, psychopathology and antisocial behaviour. She is an expert in reinforcement sensitivity and the role of threat perception in psychopathology across the lifespan. Her research aims to further our understanding of the neuropsychological mechanisms, such as punishment and reward sensitivity, goal conflict processing and behavioural inhibition deficits underpinning psychopathology (e.g., personality disorders, ADHD, depression, anxiety) and antisocial tendencies. She has published peer reviewed papers on threat processing, impulsivity and anxiety in psychopathology such as antisocial personality disorder/psychopathy, ADHD, depression and self-harm. Her research also focuses on the specific roles of affective and cognitive empathy deficits in the associations between maladaptive traits (e.g., Dark Triad, psychopathic/callous-unemotional traits, sadism) and different types of aggressive behaviour, as well as more generally in internalising and externalising psychopathology.

Dr Heym investigates these processes in general and (sub-)clinical populations across the life-span (thus, in children, adolescents or adults) using cross-sectional and longitudinal designs, as well as various experimental paradigms in combination with psychophysiological measures (such as heart rate variability and skin conductance response).

A second strand of her research focuses on intervention approaches to support vulnerable individuals. Dr Heym is interested in identifying the biochemical and neurophysiological mechanisms involved in psychological disorders (e.g., brain function, microbiota, inflammation) with the aim to evaluate or facilitate alternative interventions (e.g., Havening, bio/neurofeedback, pre/probiotic supplementation). She is involved in several projects developing online/digital and Virtual Reality interventions to support individuals with traumatic experiences, anxiety and depression. Dr Heym has been central to the creation and development of the virtual reality laboratory in the Division of Psychology by securing several equipment bids and research grants for her VR based projects. For example, her team developed a Virtual Reality Exposure Therapy for social anxiety disorder, and she supports the development of digital applications for anxiety (e.g., Fujitsu Statefulness). Another project she is involved in develops a VR Hazard Perception Test. Dr Heym supervises MSc and PhD students interested in VR research and has established a VR research interest group across several departments at NTU.

In response to Covid, Dr Heym lead a project supporting a local organisation (Living Without Abuse) in developing a Service Provider Online Intervention Toolkit to support parents and children from domestic violence and abuse background. Related to this, she is also involved in the ProChild Erasmus project that aims to support teachers recognising the signs of child abuse and neglect.

Aligned to her research interests, Dr Heym is a member of several international research consortiums, such as the

  • Imagen project - a large scale European project exploring reinforcement-related behaviour in normal brain function and psychopathology and the developmental trajectories of young people's mental health and wellbeing;
  • Centre for Health Innovation and Lifestyle Science (CHIL): An Integrated Mind-Brain-Body Approach to Health and Wellbeing (with Auckland University of Technology, New Zealand);
  • Cascade of Chaos project: antecedent conditions in the development of dark traits and antisocial behaviour (with University of Arizona, US)

Dr Heym would be interested in supervising PhD students in any of the above areas, as well as:

  • Individual differences in socio-sexual orientation and relationship behaviour; social decision making, risk taking and substance use;
  • Social attribution processes, such as blame attribution for own negative behaviour as well as the tendency of victim blaming, moral foundations and mental health stigma
  • Psychometric scale development and validation

Further information may be obtained by contacting Dr Heym directly or from the NTU Graduate School.

Dr Heym's research has been funded by DTA Alliance (as PI) and Road Safety Trust, RAC Foundation, DVSA, Royal Society of New Zealand, Erasmus+ KA2, (all as Co-I) as well as several NTU internal research funding streams. In the past, her research has also been supported by the British Psychological Society and BECTA.
