Reaction times from two conditions of a keyboard typing experiment

Description

Participants in an experiment were tasked to type the words or nonwords that they were shown on a computer screen. The nonwords were either completely random strings or else they consisted of letter bigrams that are typical in written English. The words and nonwords were five letters in length. For all participants, there were two conditions. In one condition, the keyboard was visible as normal. In the other condition, the keyboard was occluded. On each trial, the time in milliseconds taken to type the first letter was recorded. Only trials where the word was correctly typed are recorded in this data set.

Format

A data frame with 228 rows and 4 variables

subject: (factor) Identifier of participant in experiment.
keyboard: (factor) Experiment condition indicating if the keyboard visible or occluded.
condition: (factor) The experimental condition that determined the type of stimulus that was displayed: either a normal English word (normal) or a random string of letters (random) or a random string of letters with typical English letter bigrams.
log_rt: (numeric) The natural logarithm of the time to type the first letter on each trial.
