Introduction

An overlap between autism spectrum disorder (ASD), in particular Asperger Syndrome (AS), and high intellectual potential (HIP–Total IQ > 2 SD) is often discussed.

Objectives

Explore differences between homogeneous and heterogeneous Wisc-profiles among HIP children, and between HIP and ASD children, on cognitive and clinical assessments.

Methods

Forty-nine participants (mean age 11.2 years) were divided in 4 groups: High Functioning Autism (HFA), AS, Homogenous HIP and Heterogeneous HIP. Data of WISC-IV and questionnaires – Autism Quotient (AQ), Empathy Quotient (EQ), Systemizing Quotient (SQ), Children's Communication Checklist (CCC) – were compared.

(Preliminary) Results

On the WISC-IV, the Z scores curves follow similar trajectories but highlight quantitative differences between AS and heterogeneous HIP: verbal comprehension is the highest index (+1,6 SD in AS; +3,1 SD in heterogeneous HIP) followed by perceptual reasoning, working memory, and processing speed indexes (–1,2 SD in AS; +0,5 SD in heterogeneous HIP), respectively. The questionnaires show that scores of Homogenous HIP children are all in the average. Heterogeneous HIP children score 2,1 SD above average on the AQ (+1,6 SD on “Social Skills” and +1,3 SD on “Local Detail” subscales), whereas ASD children score 4 SD above average on the AQ. In addition, heterogeneous HIP children show pragmatic difficulties (–2,4 SD on the CCC, with a peak on “Area of Interest” subscale), also present in ASD children (–4 SD).

Conclusions

AS and heterogeneous HIP children show similar cognitive profiles on the WISC-IV. Furthermore, heterogeneous HIP children exhibit high scores on the AQ and have pragmatic difficulties.
