Our Research

What we provide

The Perth Voices Clinic supports research into voice hearing (and related) experiences, including routine evaluation of the effectiveness of the psychological interventions provided at the clinic. Individuals attending the clinic will have the option to join us in improving our services for all voice hearers, including adding their name to a research registry so that they can choose to be involved in future research projects. Professor Johanna Badcock is the Research Director to the Perth Voices Clinic and has published extensively in the field of voices, perception and cognition (see below for a brief biography).

Dr Georgie Paulik-White

Clinical Director, Clinical and Research Psychologist

I am a research-practitioner who is passionate about working with people with psychosis and those who hear voices. I believe that research must guide my clinical decisions in therapy, and likewise that the experiences my clients teach me about help to inform my research. I completed my PhD in voice hearing from the University of Western Australia in 2007 and have produced 26 peer reviewed publications and a textbook in the field of voice hearing and psychosis. I have worked in UHR and early psychosis, in both Sydney and Perth, and have been team leader of early psychosis programs. I also developed a novel intervention for voice hearers named Cognitive Behaviour Relating Therapy alongside colleagues in the UK (including Dr Mark Hayward, Sussex University). In 2016 I opened Perth Voices Clinic, at Murdoch University and Midland Headspace, to improve services and training of mental health professionals working with voice hearers. I am passionate about exploring the role of trauma in voice hearing and the impact of psychological interventions for trauma on voice hearing, and have ongoing collaborations on trauma interventions, including Imagery Rescripting, with Prof Arnoud Arntz (Netherlands) and Prof. Craig Steel (UK). I also helped set up the Hearing Voices Network in both WA and NSW.

Prof. Johanna Badcock

Research Director, Clinical and Research Psychologist

I am a clinical and research psychologist. Following basic training in Experimental Psychology at the University of Oxford I completed professional training as a Clinical Psychologist and a doctorate in psychology at the University of Melbourne.
I’ve spent my career examining the cognitive-perceptual, emotional and social mechanisms associated with the individual symptoms of mental illness. My work primarily employs behavioural, neuropsychological and psychophysical methods.
My research has contributed to a better understanding of the role of memory and inhibitory control in auditory hallucinations in clinical and non-clinical groups. More recent work has described some of the neural pathways involved these experiences. Together, my research is leading to better interventions for hallucinations.
My research collaborations and graduate supervision cover a broader range of interests including visual functioning in autism spectrum disorders, attitudes to mental illness, and schizotypal personality traits in the general community.
