Everyday memory and working memory in adolescents with mild intellectual disability.

★ The Verdict

Teens with mild ID show everyday memory gaps beyond mental-age expectations—plan extra scaffolding when tasks are new or complex.

✓ Read this if BCBAs working with middle-schoolers who have mild ID in school or clinic settings.

01Research in Context

01

What this study did

The team compared teens with mild intellectual disability to two groups: same-age peers and younger kids with the same mental age.

Everyone took everyday memory tests, like remembering to pass on a message, plus standard working-memory tasks.

02

What they found

The ID teens scored lower than both other groups. Their everyday slips were bigger than mental-age expectations.

Working-memory gaps showed the same pattern, hinting at a specific deficit, not just slower development.

03

How this fits with other research

Van der Molen et al. (2010) extends the same finding into an action plan: the same teen group can improve verbal short-term memory after short computerized training.

Chen et al. (2013) looks like a contradiction. Kids with coordination disorder also flunk everyday memory, but the gap disappears once verbal IQ is held steady. The ID study kept mental-age matches, so the deficit stays even after language level is controlled.

Danielsson et al. (2012) widens the lens. Non-verbal working memory stays weak in ID, yet verbal fluency and task-switching match mental-age peers, confirming memory is a pinch point, not global executive trouble.

04

Why it matters

For BCBAs, the message is clear: expect memory failures that seem 'too low' even for the learner's language level. Break new tasks into tiny visible steps, use external cues, and rehearse routines until they are automatic. Try the brief computerized training from the 2010 RCT as a warm-up before academic blocks; it may give a quick verbal-memory boost that transfers to story recall and math.

03Original abstract

Everyday memory and its relationship to working memory was investigated in adolescents with mild intellectual disability and compared to typically developing adolescents of the same age (CA) and younger children matched on mental age (MA). Results showed a delay on almost all memory measures for the adolescents with mild intellectual disability compared to the CA control adolescents. Compared to the MA control children, the adolescents with mild intellectual disability performed less well on a general everyday memory index. Only some significant associations were found between everyday memory and working memory for the mild intellectual disability group. These findings were interpreted to suggest that adolescents with mild intellectual disability have difficulty in making optimal use of their working memory when new or complex situations tax their abilities.
