    Abstract

    The enhanced cognitive interview (ECI) has been shown to increase the correct memory recall of a diverse range of participant types, without an increase in the number of incorrect or confabulated details. However, it has rarely been used with a sample of adults with a learning disability, who have historically been considered unreliable witnesses due to memory deficits associated with this population limiting the accuracy and completeness of their memory recall. This study aimed to fill this gap in the research literature, by comparing the memory recall of twenty-one adults with a mild learning disability (IQ 50-70) who attended day centres and twenty-one adults from the general population, using either an ECI or a structured interview (STI), approximately one and a half to two hours after viewing a film of a staged non-violent mugging. It was found that the recall of adults with a learning disability was overall less complete and less accurate than that of their counterparts from the general population. Nevertheless, for both adults with a learning disability and those from the general population the ECI was more effective than the SI in enhancing recall of correct person, action and conversation (gist) detail, without increasing the number of incorrect or confabulated details reported. Additionally, the accuracy of all information reported was similar across interview types (81% for the ECI and 80% for the STI). Overall, the findings suggest that ECI can enable adults with a learning disability to provide better evidence in criminal proceedings.
