'Everyday memory' impairments in autism spectrum disorders.

de Graaf et al. (2011) compared teens with autism to same-age peers without autism. They used two quick memory tests: one for everyday tasks like remembering to hand in homework, and one for recalling a short word list.

All teens took the tests in the same quiet room. The study asked: do autistic teens struggle with everyday memory more than their peers?

The autistic teens scored much lower on both tests. They forgot everyday tasks more often and recalled fewer words.

The gap was large enough that the authors call it a clear everyday memory deficit tied to social-communication challenges.

Simó-Pinatella et al. (2013) conceptually replicate this result. They show autistic kids forget time-based tasks (like taking meds at 3 pm) but do fine on event-based tasks (like taking meds when a bell rings). Together, the studies say: if the cue is inside the teen’s head (a time or plan), it is fragile; if the cue is outside (a sound or prompt), it is safer.

Altgassen et al. (2012) extend the finding to adults. In a naturalistic breakfast task, adults with autism still showed no self-compensation. The deficit does not fade with age, so planners and external prompts remain useful lifelong.

Altgassen et al. (2019) add a twist: offering a personal reward boosts neurotypical teens’ time-based memory but not autistic teens’. This finding extends de Graaf et al. (2011) by showing that motivation helps typical peers yet leaves autistic teens unchanged—so rewards alone won’t fix the problem.

Add one quick prospective-memory probe to your autism assessments: ask the teen to remind you to open the door in five minutes. A missed cue signals a need for external supports like phone alarms, picture schedules, or peer prompts. Do not assume older clients or sweet incentives will close the gap—plan for lifelong scaffolding instead.
