No evidence of association between autism spectrum quotient and spontaneous mental time travel in a general adult sample performing an online vigilance task

Abstract

AbstractEvidence supports the dissociation of voluntary and spontaneous routes to past and future thinking, collectively referred to as mental time travel (MTT). If the diminished voluntary MTT ability found in autism spectrum disorders (ASD) is attributable to a deficit in constructive/generative processes not necessary for spontaneous MTT, ASD traits (Autism Spectrum Quotient score) in a general adult sample should not be related to total spontaneous thoughts, probability of past or future thoughts, or probability of specific thoughts during an undemanding vigilance task. Results supported this hypothesis: AQ was not associated with total spontaneous thoughts and did not significantly predict the other measures. This is the first study to explore spontaneous MTT in relation to ASD traits, further supporting the argument that voluntary MTT may be compromised in ASD due to reliance on constructive/generative processes and reinforcing the notion of dissociable cognitive routes to MTT.
