Abstract

To date, evidence-based guidelines for interviewing children with Autism Spectrum Disorder (ASD) do not exist. Several different evidence-based interview protocols exist worldwide, but these were empirically derived based research with typically developing (TD) children. The present investigation is a follow-up study to an initial study that compared event memory and suggestibility among TD and ASD children. In the original study, 68 control (i.e., TD) and 30 ASD children participated in a three-session study. In session 1, children individually participated in an interactive magic show. Approximately 1-week later, in Session 2, children were given true reminders and false suggestions about the magic show. About 4-days later, in Session 3, children were given an initial memory test (i.e., two-weeks after the staged event). In the current follow-up study, we sought to examine whether autobiographical reports among ASD children differed from control children following a 10-month delay. Approximately 10-months after the staged event, we located and retested 41 control and 22 ASD children. In addition to retaking the initial memory test, children were given a lineup identification and object recognition task. The results revealed both ASD and control children’s free recall was at the floor at the 10-month delay. Compared to control children, more ASD children recalled no details about the magic show in the 10-month than the two-week delay interview. Control children recalled more correct utterances than ASD children regardless of the delay period. Children’s recognition memory also worsened with the 10-month delay. Both groups showed memory facilitation effects at both the two-week and 10-month delayed interviews. Both groups showed memory misinformation effects at the two-week interview. At the 10-month interview, control children showed misinformation effects. In children with ASD, their false assent rate to non-suggested items was equally high as their false assent rate to suggested items. Similar patterns were found among control and ASD children in their performance on the lineup identification and object recognition tasks. In addition to the theoretical contribution, these results are important to professionals who interview ASD children by further understanding autobiographical memory in this vulnerable population. These results can be used to develop evidence based guidelines for interviewing children with ASD and to guide early intervention programs.
