“…While difficulties in time-based PM in children and adults with ASD have been consistently reported in the literature (e.g., Altgassen et al, 2009Altgassen et al, , 2019Dehnavi & Khan, 2023;Henry et al, 2014;Kretschmer et al, 2014;Landsiedel & Williams, 2020;Williams et al, 2013Williams et al, , 2014, findings regarding event-based PM in ASD seem to be mixed. There are several studies that found spared event-based PM performance in ASD (Altgassen & Koch, 2014;Altgassen, Phillips, et al, 2010;Henry et al, 2014;Sheppard et al, 2016;Williams et al, 2013), while others reported reduced performance in ASD (Brandimonte et al, 2011;Kretschmer et al, 2014;Yi et al, 2014).…”

Prospective memory (PM) is the ability to remember to carry out intended actions in the future. The present study investigated the effects of episodic future thinking (EFT) and enactment encoding (EE) on PM performance in autistic adults (ASD). A total of 72 autistic individuals and 70 controls matched for age, gender, and cognitive abilities completed a computerized version of the Dresden breakfast Task, which required participants to prepare breakfast following a set of rules and time restrictions. A two (group: ASD vs. controls) by three (encoding condition: EFT vs. EE vs. standard) between‐subjects design was applied. Participants were either instructed to engage in EFT or EE to prepare to the different tasks prior to performing the Dresden breakfast or received standard instructions. Analyses of variance were conducted. Autism‐spectrum‐disorders (ASD) participants did not differ from control participants in their PM performance, regardless of which strategy they used. Compared to the standard condition, EE but not EFT improved time‐based PM performance in all participants. This is the first study to find spared time‐based PM performance in autistic individuals. The results confirm earlier results of beneficial effects of EE on PM performance. Findings are discussed with regards to the methodology used, sample composition as well as autistic characteristics.
