Working Memory and ADHD
By Inderbir Kaur Sandhu, Ph.D
Does the Working Memory score on the WISC-IV (which measures auditory
attention span) diagnose ADHD?
No. There is no direct diagnosis for ADHD by looking at the WISC-IV
scores alone, as it is not a diagnostic test. There are tests
specifically to diagnose ADHD. Furthermore, there are many ADHD subtypes
such as the predominantly inattentive; hyperactive-impulsive and the
combined type. Moreover, most children who have been diagnosed with ADHD
may have been on medication and there may be a difference here.
However, it has been found that children with ADHD usually have scores
of Processing Speed and Working memory, which is lower than Verbal
Comprehension and Perceptual Reasoning. Based on the subsets, they
appear to perform poorly on the Coding and Arithmetic subsets. If a
child scores poorly in working memory and/or processing speed and the
gap is large with verbal comprehension and perceptual reasoning, it
would be something to be concerned about and one may need to do further
tests to determine or rule out developmental concerns. Speak to a
psychologist for further testing.
