Practice is the best of all instructors-Effects of enactment encoding and episodic future thinking on prospective memory performance in high-functioning adults with autism spectrum disorder.
Have high-functioning autistic adults physically rehearse future steps to improve their time-based memory.
01Research in Context
What this study did
Greenlee et al. (2024) worked with high-functioning adults with autism. Half tried a new way to remember future tasks. They moved their bodies while learning the steps.
The other half pictured the future or got plain spoken rules. Everyone then had to do a time-based job later in the lab.
What they found
Moving while learning worked best. Both autistic and non-autistic adults scored higher on the later task.
Just picturing the future added no extra boost. Plain rules helped the least.
How this fits with other research
Kretschmer et al. (2014) tried if-then plans with the same adult group. Their gains were small and shaky. The new motor method gives a clearer, stronger lift.
Peisley et al. (2020) used game rewards to teach the same skill to young kids with autism. Rewards worked for children; enactment works for adults. Together they show you can match the tool to the age.
Grainger et al. (2017) showed kids with autism already get the enactment boost. The new study proves you can turn that natural boost into a teachable tactic for grown-ups.
Why it matters
Next time you teach an adult client to take meds or start a work task on time, have them stand up and walk through the steps. A quick rehearsal beats extra talk or mental pictures. You get a cheap, fast way to lift time-based memory for autistic adults without extra tech or cost.

03Original abstract
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.
