Assessment & Research

Cognitive profiles in adolescents with mental retardation.

Vicari et al. (1992) · Journal of intellectual disability research : JIDR 1992
★ The Verdict

Use a quick skill-by-skill battery instead of one IQ score when planning ABA for teens with ID.

✓ Read this if BCBAs writing assessment plans for high-schoolers with intellectual disability.
✗ Skip if Clinicians only working with adults or mild learning issues.

01Research in Context

01

What this study did

The team tested 30 high-school students with intellectual disability.

Each teen took a full battery: memory, language, attention, and problem-solving tests.

They wanted to see if one IQ score could capture each kid’s real strengths and gaps.

02

What they found

No two teens looked the same.

One boy had strong memory but weak language.

Another girl solved puzzles well yet forgot instructions fast.

The study showed that a single IQ number hides these ups and downs.

03

How this fits with other research

Van Den Heuvel et al. (2018) followed younger kids with ID for two years and found the same uneven skills.

Their work extends this 1992 snapshot by proving the patterns stay mixed over time.

Pierce et al. (1994) used the same case-series method for feeding issues and also found unique profiles.

Together, these papers say: test the specific skill, not the label.

04

Why it matters

When you assess a teen with ID, run short tests for memory, language, and attention. Pick targets from the weakest area and build goals from the strongest. This gives you clearer baselines and better treatment plans than IQ alone.

03Original abstract

Cognitive profiles of performance were obtained from a selected group of adolescent subjects with mental retardation (MR) (n = 32; mean age: 15.4 years, S.D. = 3.7) by means of an ad hoc neuropsychological battery. On the basis of each subject's IQ, the experimental sample was divided into three homogeneous subgroups (severely, moderately and mildly retarded) and cognitive performances obtained in the battery tests were compared. Subsequently, in order to clarify the qualitative aspects of MR, the cognitive patterns of subjects with the same IQ and chronological age were examined. Altogether, from a neuropsychological point of view, the results of this study seem to support the hypothesis that MR is a heterogeneous condition of cognitive deficits (some abilities are better preserved than others) and indicate that a set of multiple tests exploring single cognitive functions is needed in order to describe cognitive profiles in MR.
