In rcollectadhd: Collection of Data Sets Containing ADHD Related Data

Children's reaction times (milliseconds) to stimuli of different nature, arranged with four response columns

Description

The data (Keselman et al., 2003) represent the reaction times in milliseconds of children with attention-deficit hyperactivity (ADHD) and non-ADHD children when they are presented four kinds of inputs: a target alone or an arrow stimuli incongruent, congruent and neutral to the target. According to the authors, the dataset was artificially generated from the summary measures given in the original study by Jonkman et al. (1999), in groups of 20 and 10 children to create an unbalanced design.

Usage
