Using a forced-choice explanation task, children's understanding of social-psychological, physical, and biological causal explanations of disabilities was considered. We presented 79 children (26 4- to 5-year-olds, 26 6- to 7-year-olds, and 27 10- to 11-year-olds)…

The development of two dimensions of attention was compared: alertness/arousal and inhibitory control. Method: Children with ADHD (N…

Background: Deficits in executive functioning are supposed to have a predisposing influence on impulsive or aggressive behaviour. We tested the hypothesis that oppositional-defiant disorder (ODD) children with or without attention deficit hyperactivity disorder (ADHD) have problems in executive functioning. Method: Seventy-seven 7- to 12-year-old…

In this paper we examine the characteristics of preschool attention deficit hyperactivity disorder (ADHD) from both mental disorder and developmental psychopathology points of view. The equivalence of preschool and school-aged hyperactivity as a behavioral dimension is highlighted together with the potential value of extending the use of the ADHD…

In recent years a growing body of evidence has implicated deficits in the automaticity of fundamental facts such as word and number recognition in a range of disorders: including attention deficit hyperactivity disorder, dyslexia, apraxia and autism. Variously described as habits, fluency, chunking and over learning, automatic processes are best…
