I attached a data here called image_study. The “image_study.csv” dataset contains data from a study examining the speed of classification of two different types of image: artworks, and natural images. There are four variables in the data as follows:
participant – a unique identifier for each participant
image – a unique identifier for each image
image_type – a factor indicating whether a given image is an Artwork or a Natural image.
RT – reaction time in milliseconds
I want to model reaction times (RT) as a function of the other variables in the dataset. The purpose here is to examine the effect of Image-type on RT.
