The goal of this study is to create a formal, quantitative methodology to determine what is the most beneficial dose of Central Nervous System (CNS) stimulant (Ritalin, methylphenidate) to improve cognitive and behavioral function of children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) individually. If successful, it will change the way in which the dose of CNS stimulant for treating ADHD is determined for children in need of therapeutic intervention. The project will be focused on developing the necessary methodology to analyze the children's data with the drift-decision model (DDM), and to develop the required technology, i.e., a computer game with which to measure cognitive/behavioral function and its validation with eye-tracking measurements.

Task choice
Subjects will perform different cognitive tasks and we will record their choices.
Time frame: At the time of testing (the investigators are measuring acute effects, not following outcomes based on a treatment)
Reaction time
The investigators record how long it took them to make their choices.
Time frame: At the time of testing (the investigators are measuring acute effects, not following outcomes based on a treatment)
Eye position
The tasks are eye movement based. The investigators record where the subjects were looking as voltages, which are converted to x/y coordinates through a calibration, throughout the different events of the task.
