Zusammenfassung:Abstract Cognition in individuals with Autism Spectrum Disorder (ASD) shows large variability. Nonverbal tests can be more suitable for cognitive assessment in this group. We investigated cognitive abilities in ASD using the SON-R 6-40 Nonverbal Intelligence Test. A total of 37 individuals with ASD (AG) aged 6-24 years participated. Cognitive assessment of the AG was done using the SON-R 6-40 and performance compared with the standardized sample which served as the control group (CG). Results showed lower subtest scores in the AG than in the CG. Approximately 84% of the AG had intellectual disability according to IQ scores. Individuals with preserved speech in the AG had higher IQ scores than patients without preserved speech. There was no relationship between intelligence and ASD symptom severity as reported by families. Resumo A cognição de indivíduos com Transtorno do Espectro Autista (TEA) apresenta grande variabilidade. Testes não-verbais podem ser mais adequados para avaliação cognitiva desta população. Investigou-se as habilidades cognitivas de indivíduos com TEA a partir do desempenho no Teste não verbal de inteligência SON-R 6-40. Participaram 37 indivíduos com TEA (GTEA) entre 6 e 24 anos, cujo desempenho no SON-R 6-40 foi comparado ao da amostra normativa do instrumento (GC). Houve pior desempenho do GTEA em todos os subtestes, com diferença significativa em relação ao GC. Quase 84% do GTEA apresentou QI compatível com deficiência intelectual. Aqueles com fala preservada apresentaram desempenho superior ao grupo não-verbal. Não houve relação entre inteligência e gravidade dos sintomas conforme relato das famílias.
