Event-based prospective memory in mildly and severely autistic children.
Severe autism blocks remembering to act later, but strong cues and motivation fix it.
01Research in Context
What this study did
The team asked kids to remember to do small jobs later. One job was to hand over a card when they saw a red cup.
They tested three groups: typically developing kids, kids with mild autism, and kids with severe autism.
Each child played a short game while the adult watched if they remembered the job without being told again.
What they found
Kids with severe autism forgot the job more often than the other two groups.
Kids with mild autism did about the same as typical kids.
When the job felt fun or important, even severely autistic kids remembered better, almost closing the gap.
How this fits with other research
Hsieh et al. (2014) and Naito et al. (2020) saw the same kind of future-memory slip in younger, high-functioning kids. The new data show the problem stays around when autism is severe.
Feldman et al. (1999) already showed autistic kids misjudge when they are ready to recall. The 2016 study adds that they also miss future cues, not just past facts.
Maras et al. (2020) found no memory-monitoring gap in autistic adults answering eyewitness questions. The jobs were different: looking back versus remembering forward. That explains the clash.
Why it matters
Check if your learner’s autism is severe, not just diagnosed. If it is, add extra cues, rewards, or peer models when you set future tasks like handing in homework or turning off a timer. Make the cue stand out and the payoff clear, and performance can jump to typical levels.

03Original abstract
BACKGROUND: There is a growing body of research into the development of prospective memory (PM) in typically developing children but research is limited in autistic children (Aut) and rarely includes children with more severe symptoms. AIMS: This study is the first to specifically compare event-based PM in severely autistic children to mildly autistic and typically developing children. METHODS AND PROCEDURES: Fourteen mildly autistic children and 14 severely autistic children, aged 5-13 years, were matched for educational attainment with 26 typically developing children aged 5-6 years. Three PM tasks and a retrospective memory task were administered. OUTCOMES AND RESULTS: Results showed that severely autistic children performed less well than typically developing children on two PM tasks but mildly autistic children did not differ from either group. No group differences were found on the most motivating (a toy reward) task. CONCLUSIONS AND IMPLICATIONS: The findings suggest naturalistic tasks and motivation are important factors in PM success in severely autistic children and highlights the need to consider the heterogeneity of autism and symptom severity in relation to performance on event-based PM tasks.
