Choice Data

The database data.sqlite3 contains four tables: instruction, choiceset, participant and trial. The first two tables, instruction and choiceset, contain the materials used in the experiment: the instruction table records text messages presented at each trial, and the choiceset table records values of alternatives. The other two tables, participant and trial, contain the collected data: the participant table records whether participant was engaged in the task, and the trial table records participants' responses. The R script shows how to load the collected data onto a single data frame.


The R script uses the following libraries:

RSQLite (

Hmisc (

dplyr (

tidyr (

ggplot2 (

Fixation Data

The sqlite3 database fixation.sqlite3 contains one table: fixation. This table has 6 columns:

within_trial_index: 0 indicates the first fixation after the trial onset, 1 indicates the second fixation, 2 indicates the third fixation, and so on
duration: fixation duration in milliseconds
