Brief report: self-based and mechanical-based future thinking in children with autism spectrum disorder

This brief report is a partial replication of the study by Jackson and Atance (J Dev Disabil 14:40–45, 2008) assessing nonverbal Self-based and Mechanicalbased future thinking (FT) in children with Autism Spectrum Disorder (ASD). In a first step, these tasks were administered to 30 children with ASD. The two Self-based tasks were then modified as a verbal component could not be completely ruled out. Consequently, 77 children with ASD and 77 children with typical development received the modified Self-based FT tasks and the Mechanical-based FT tasks. We partially replicated the previous findings. Participants with ASD had impaired FT in both kinds of tasks and both groups performed better on tasks assessing Mechanical-based FT than Self-based FT. These results suggest that impairments of FT in ASD are not limited to Self-Projection.
