Wisconsin Card Sorting Test-Learning Potential: Usefulness for Assessing Children with Autism Spectrum Disorder.

The team tested a new twist on the Wisconsin Card Sorting Test. They call it WCST-LP. The LP stands for learning potential.

Kids with autism and typical kids took the test. The study asked: does this new score really measure learning? does IQ get in the way? and do the scores link to daily verbal and social skills?

WCST-LP scores held up. They showed real learning in kids with autism. IQ did not skew the numbers.

Only in the autism group did the scores tie to how well the child talks and plays with others.

Siegel et al. (1986) did the same kind of check thirty-four years earlier. They showed CARS and ASIEP can tell autism from intellectual disability. Gómez-Pérez et al. (2020) now show WCST-LP can spot learning without being fooled by IQ.

Poppes et al. (2016) looked at working memory in autism and found mixed results. Their data hint that some thinking tests miss small but real gaps. WCST-LP may catch those gaps better.

Berument et al. (2005) and Sappok et al. (2013) warn that many tools over-diagnose autism when ID is present. WCST-LP avoids that trap. It stays clean even when IQ is low.

You now have a quick, IQ-free way to see if a child with autism can learn new rules. Use the score to set realistic goals for language and social programs. If WCST-LP is high, push harder on complex skills. If it is low, break tasks into smaller steps and give more prompts.
