    Abstract

    The present experiment examined the role of co-witnesses in minimising the misinformation effect in adolescents when completing a Self-Administered Interview (SAI). A between-subjects design with three conditions (Co-Witness, Misinformation and Individual) was employed. The respondent sample included 60 participants (31 males and 29 females), ranging from 16 to 18 years of age (M age = 16.75, SD = .70). All participants were shown a reconstruction of a videotaped crime and asked to recall their memories in a subsequent individual SAI. Both the Co-Witness and Misinformation condition were asked to complete their individual SAI once they had discussed the event with another participant. However, half the participants within the Misinformation condition received misleading information before discussion with a co-witness in order to assess whether this would be incorporated into subsequent recall. Results of this research found that co-witness discussion is not effective in reducing the misinformation effect in adolescent eyewitnesses when completing the SAI. Nonetheless, a mediating relationship was discovered between specific Person and Object recall and higher inclusion of Action-specific details. Ultimately, this research is able to address a fundamental gap within the research literature through its focus on adolescent eyewitnesses and the SAI.
