ABSTRACT
Outstanding skills, including special isolated skills (SIS) and perceptual peaks (PP) are frequent features of autism. However, their reported prevalence varies between studies and their co-occurrence is unknown. We determined the prevalence of SIS in a large group of 254 autistic individuals and searched for PP in 46 of these autistic individuals and 46 intelligence and age-matched typically developing controls. The prevalence of SIS among autistic individuals was 62.5% and that of PP was 58% (13% in controls). The prevalence of SIS increased with intelligence and age. The existence of an SIS in a particular modality was not associated with the presence of a PP in the same modality. This suggests that talents involve an experience-dependent component in addition to genetically defined alterations of perceptual encoding.

Mentions: We examined the prevalence of SIS in 254 autistic individuals. Table 3a shows the characteristics of the participants including age and intelligence level and Fig. 2 illustrates the prevalence by domain. The proportion of autistic individuals with at least one reported SIS was 62.6 % (159/254). Special memory skills were the most frequently reported SIS, and were found in 52.5 % (127/242) of autistic individuals. Among autistic individuals with a clinically defined special skill, 71.7 % (114/159) had more than one SIS. We also examined how frequently SIS are lost, which showed that SIS are lost in 5–22 % (mean of 12 %) of individuals, depending on the type of skill. However, the loss of all abilities was uncommon (5 %) (Table S2).Table 3

ABSTRACT
Outstanding skills, including special isolated skills (SIS) and perceptual peaks (PP) are frequent features of autism. However, their reported prevalence varies between studies and their co-occurrence is unknown. We determined the prevalence of SIS in a large group of 254 autistic individuals and searched for PP in 46 of these autistic individuals and 46 intelligence and age-matched typically developing controls. The prevalence of SIS among autistic individuals was 62.5% and that of PP was 58% (13% in controls). The prevalence of SIS increased with intelligence and age. The existence of an SIS in a particular modality was not associated with the presence of a PP in the same modality. This suggests that talents involve an experience-dependent component in addition to genetically defined alterations of perceptual encoding.
