Authors' interpretation in the Discussion, not a tested result: they attribute the conflict with inspection-time studies (Scheuffgen et al. 2000; Wallace et al. 2009; Barbeau et al. 2013) to possible ceiling effects in inspection tasks, and advocate standardized processing speed measures.

"The discrepancy between the current findings and the inspection time findings could be due to the inspection tasks producing ceiling effects, and thus it may not have been sensitive enough to detect differences in processing speed in ASD."

• The processing speed deficit in adults with ASD appears on each of the three standardized subtests: Trail Making A, Symbol Coding, and Category Fluency — related
• Adults with ASD without intellectual disability show a large deficit in composite processing speed versus IQ-matched controls on standardized measures — related
• Processing speed in adults with ASD shows no significant association with SAS-II social adjustment, and only a near-significant positive association with GAF functioning — related
• Studies relying exclusively on the Applied Problems subtest are likely to miss small but meaningful influences on early math achievement because the measure is less sensitive to variation among young children — related
• Slower processing speed in adults with ASD is associated with greater impairment on ADOS Communication and Reciprocal Social Interaction scores — related
