Abstract

Autism spectrum disorders (ASD) are associated with cognitive dysfunctions, including mental time travel (MTT). However, findings on diminished MTT ability may be confounded by a number of factors, including the individuals’ language ability, factors related to the MTT task and the demographic factors of participants. The present study provided a meta-analysis of MTT ability in people with ASD. The results showed significant overall reductions in MTT ability in people with ASD. Moderator analyses revealed that the variables examined did not explain the reduction in MTT ability. These findings suggest that MTT ability is diminished in people with ASD and that the degree of this diminishment may not depend on the characteristics of measures or demographic variables of people with ASD.

Experiential index included different measures, such as emotion, sensory details, vividness, important intensity, etc. A nonweighted average effect size of all the measures was calculated for each study.

Regarding the number of details, we included papers that measured MTT performance with the number of details included in participants’ responses; in addition, papers that calculated the total score of specificity (for example, a specific event was scored as 4, an extended event was scored as 3, a categorized event was scored as 2, a semantic associated event was scored as 1, and an omission was scored as 0; then, the total score was added as the index of MTT performance) were also considered as this type of article (Chaput et al., 2013). For specificity, we included papers that reported the proportion of specific responses or number of specific responses as MTT performances. For the experiential index, we included papers that reported either self-report experiential indices (Crane et al., 2010) or experiential indices calculated by experimenters that referenced the narrative (Brown et al., 2012; Crane et al., 2010) about their emotion, sensory details, vividness, etc. as MTT performance.

One study (Lind and Bowler, 2010) was excluded from this analysis because it did not report AM and EFT data separately.
