In eyetrackingR: Eye-Tracking Data Analysis

#' Data collected in an infant eyetracking study
#' 
#' Data from a simple 2-alternative forced choice (2AFC) word recognition task administered to 19- 
#' and 24-month-olds. On each trial, infants were shown a picture of an animate object (e.g., a 
#' horse) and an inanimate object (e.g., a spoon). After inspecting the images, they disappeared and
#' they heard a label referring to one of them (e.g., "The horse is nearby!"). Finally, the objects 
#' re-appeared on the screen and they were prompted to look at the target (e.g., "Look at the 
#' horse!").
