iIIRG 2022 - MASTERCLASS (June 20-21)

Supporting Vulnerable Individuals to Give Best Evidence


This two day pre-conference Masterclass will be led by Dr. Rachel Wilcock, Dr. Brendan O’Mahony, Jan Jones, and Fiona Simpson.


Who should attend:

  • Policy makers, trainers and practitioners in the fields of investigative and intelligence interviewing
  • Researchers working in the field of applied memory and investigative interviewing


Please note: the Masterclass is now full and no longer open for registration. 


This workshop is aimed towards policy makers and practitioners in the field of investigative interviewing as well as researchers in the field of applied memory and investigative interviewing who have an interest in developing methods to support vulnerable individuals.  Designed with practitioners in mind, this Masterclass will begin by examining the nature of vulnerability and the challenges Criminal Justice Practitioners may face when identifying vulnerable individuals.  

Consideration will be then be given to a number of different vulnerable groups (older adults, individuals with intellectual disability (learning disabilities), individuals with mental health problems, and children with and without autism). These groups will be considered from the perspective of their likely cognitive profile as well as what can be done to support them during an investigative interview.  This will include illustration and demonstrations of techniques used by Registered Intermediaries when they support these vulnerable groups. 

Across the two days we will consider vulnerable witnesses but there will also be focus given to vulnerable suspects with intellectual disability and mental health problems.


Dr Rachel Wilcock is a Reader in Psychology and has been Head of the Department of Psychology at the University of Winchester since September 2016.  Her research interests focus on improving methods of eliciting accurate evidence from eyewitnesses, particularly those deemed to be vulnerable: children, elderly, those with intellectual disability and autistic individuals. She has published extensively in the area of vulnerable witnesses and written an authored book on eyewitness identification.  Her most recent ESRC funded research has been on supporting child witnesses with and without autism. As part of this she has worked closely with a number of Registered Intermediaries.  In the past Rachel developed, lead, and taught a MSc Investigative Psychology programme that was largely aimed towards Criminal Justice practitioners. Rachel currently contributes to a BSc Psychology third year module on Eyewitness Psychology and a MSc Forensic Psychology module on Investigative Psychology, as well as supervising BSc Psychology, MSc Forensic Psychology and PhD psychology students.
