The current study using the longitudinal study in preschool children to exam three study issues: 1) using the neuropsychological functions (ie. Behavioral inhibition, delay aversion, the variability of reaction time) among the preschool children predict the ADHD diagnosis and behavior symptoms in 1.5 years later. 2) using the behavior inhibition, delay aversion and the variability of reaction time (using the parameter among Gaussian distribution and ex-Gaussian distribution) explore the association between attention and motor inhibition problems. 3) explore the transaction effect between the neuropsychological functions and family function and parenting to predict ADHD comorbidity with oppositional defiant disorder.4) explore the association between the internalizing/ externalizing problems of ADHD and temperament. The current study has opportunity to describe and to answer the complicated problems for heterogeneous neuropsychological deficits in ADHD, and to elucidate the core issues for ADHD have comorbid with ODD. The most important contribution is to offer the empirical evidence to make a clean suggestion in ADHD diagnosis and intervention in preschool age.

We will recruit 100 typical developmental control and 120 ADHD high risk preschool children at time 1, and we using the diagnosis at time 2 to have three groups in this study (ADHD persistent, ADHD remission and typical developmental control).
