Description

This data set involves normally developing children 9 years of age presented visual simuli on a computer monitor. There are three different experimental conditions, according to the length of the delay after which the stimulus was displayed on the screen. Each subject experienced each condition eight times, and these 24 trials were given in random order. These data give the 82 children for whom there are complete measurements among over 200 total subjects.

Usage

Format

This data frame consists of 82 children (the rows) and their 24 responses (the columns) to the stimulus presented. The response is recorded in milliseconds. The columns are not in the order in which the stimuli were presented to the children; rather, they are arranged into three blocks of eight columns each so that each eight-column block contains only trials from one of the three conditions.
