Hypothesis

Do individuals with Asperger syndrome show the same advantages in Raven's Progressive Matrices as those with autism?

Conclusion

Asperger individuals demonstrate significant advantages in Raven's Progressive Matrices compared to their Wechsler scores, indicating a common cognitive mechanism across the autistic spectrum.

Supporting Evidence

  • Asperger adults scored significantly higher on Raven's Progressive Matrices than on Wechsler Full-Scale IQ.
  • Asperger children also showed an RPM advantage over Wechsler Performance scores.
  • Both Asperger adults and children had RPM scores reflecting their Wechsler peaks of ability.

Takeaway

This study found that people with Asperger syndrome can be really good at solving certain puzzles, showing that they have unique strengths in thinking.

Methodology

Participants completed Raven's Progressive Matrices and Wechsler scales to assess their intelligence.

Potential Biases

Potential biases in participant selection and diagnostic criteria may affect the generalizability of the findings.

Limitations

Participant Demographics

32 Asperger adults (ages 16-49) and 25 Asperger children (ages 7-15) were included in the study.
