## Reaction Time (RT) Data Set

### Description

This data set involves normally developing children 9 years of age presented with two visual simuli on a computer monitor. The left image is the target stimuli and on the right is either an exact copy or a mirror image of the target stimuli. The child must press one key if it is a copy or another key if it is a mirror image. The data consists of the reaction times (RT) of the 197 children who provided correct responses for all 6 task trials.

### Usage

    data(RTdata)

### Format

This data frame consists of 197 children (the rows) and their 6 responses (the columns) to the stimulus presented. The response (RT) is recorded in milliseconds.
