| Abstract: Difficulties attending have been frequently observed in autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). While preliminary research suggests that co-occurring symptoms of ASD and ADHD are associated with greater delays in adaptive and cognitive functioning, little research has been devoted to examining attentional deficits in comorbidity. Four groups of 8- to 10-year-old children were administered the Conners Continuous Performance Test (CCPT-II): ASD only (n=16), ADHD only (n=16), comorbid ASD and ADHD (n=16), and a neurotypical group (NT; n=16). Children with comorbidity engaged in greatest behaviors of hyperactivity/impulsivity (M = 66.39, SD = 7.90), inattention (M = 64.18, SD = 9.20), and response time variability (RT; M = 61.67, SD = 8.86). No differences were found in comorbidity and ASD (p = .09) on commission errors, comorbidity and ADHD (p = .61) on omission errors, or comorbidity and ADHD (p = .24) on RT. The comorbid group was significantly different than ASD (p = .001), ADHD (p = .02), and controls (p < .001) on sustained attention. Parents and teachers reported similar behavior profiles in ADHD and comorbidity. Results indicate that comorbidity reflects both diagnoses with overall greater difficulties in attention. Suggestions for treatment and future research will be discussed. |
