AB  - OBJECTIVES: To study cognitive test profiles with a focus on processing speed in 
      a representative group of preschool children with autism spectrum disorder (ASD) 
      and relate processing speed to adaptive functioning. METHODS: Cognitive 
      assessments were performed in 190 3.6-6.6-year-old children (164 boys and 26 
      girls) with ASD, using either Griffiths' developmental scales (n = 77) or the 
      Wechsler Preschool and Primary Scale of Intelligence-Third Edition (WPPSI-III) (n 
      = 113). Cognitive data were related to adaptive functioning as measured by 
      Vineland Adaptive Behavior Scales (VABS). RESULTS: Cognitive profiles were 
      characterized by low verbal skills. Low processing speed quotients (PSQs) were 
      found in 66 (78%) of the 85 children who were able to participate in the 
      processing speed subtests. Except for Socialization, all VABS domains 
      (Communication, Motor Skills, Daily Living Skills, and Adaptive Behavior 
      Composite scores) correlated significantly with PSQ. Multiple regression analysis 
      showed that PSQ predicted 38%, 35%, 34%, and 37% of the variance for 
      Communication, Daily Living Skills, Motor Skills, and total Adaptive Composite 
      scores, respectively. CONCLUSION: Preschool children with ASD had uneven 
      cognitive profiles with low verbal skills, and, relatively, even lower PSQs. 
      Except for Socialization, adaptive functioning was predicted to a considerable 
      degree by PSQ.
