The success of witness interviews in the criminal justice system depends on the accuracy of information obtained, which is a function of both amount and quality of information. Attempts to enhance witness retrieval such as mental reinstatement of context have been designed with typically developed adults in mind. In this paper, the relative benefits of mental and sketch reinstatement mnemonics are explored with both typically developing children and children with autism. Children watched a crime event video, and their retrieval of event information was examined in free and probed recall phases of a cognitive interview. As expected, typically developing children recalled more correct information of all types than children with autism during free and probed recall phases.Sketching during free recall was more beneficial for both groups in both phases in reducing the amount of incorrect items, but the relative effect of sketching on enhancing retrieval accuracy was greater for children with autism. The results indicate the benefits of choosing retrieval mnemonics that are sensitive to the specific impairments of autistic individuals, and suggest that retrieval accuracy during interviews can be enhanced, in some cases to the same level as that of typically developing individuals.

Vulnerable witnesses (e.g. children and adults with communication impairment) face many barriers to testifying and achieving justice when participating in the criminal justice system. To date, reforms have been implemented in Australia to address these, yet the barriers remain. Several other countries have implemented an intermediary scheme, whereby an independent third party assists vulnerable witnesses to understand the questions and processes encountered during interviews and trials, and helps witnesses to be understood. This study provides a qualitative analysis of stakeholders' (N ¼ 25 professionals) perceptions regarding the potential benefits of implementing an intermediary scheme in Australia. While all participants demonstrated an open-minded attitude to new reform in this area, their perspectives did not support the introduction of an intermediary scheme at this time. Stakeholders highlighted the need for improved use and effectiveness of current measures, and expressed concern about adding further complication to the system.Vulnerable witnesses, such as children or people with a physical, cognitive, social or communication impairment, face many barriers when accessing the criminal justice system. These difficulties have been well-articulated in previous research.

Since 2004, witness intermediaries have been utilised across the justice system in England and Wales. Two witness intermediary schemes based on the English model have also been introduced in Northern Ireland (2013), and more recently, in New South Wales, Australia (2016). The purpose of the intermediary in these jurisdictions is to facilitate the questioning of vulnerable witnesses, but there are clear differences in the application of the role. This paper presents the first comparative review of the three related intermediary models, and highlights the pressing need for further research into the efficacy and development of the role in practice.
