Research on executive function and Asperger’s syndrome suggests characteristics of being disinhibited and impulsive, with a relative lack of insight that affects general functioning (Eisenmajer et al. 1996; Nyden et al. 1999; Ozonoff et al. 2000; Pennington and Ozonoff 1996). Impaired executive function can also affect the cognitive control of emotions. Clinical experience indicates there is a tendency to react to emotional cues without thinking.
