Noguchi, T., & Stewart, N. (2014). In the attraction, compromise, and similarity effects, alternatives are repeatedly compared in pairs on single dimensions. Cognition, 132, 44–56. doi: 10.1016/ j.cognition.2014.03.006

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. Dependencies

The R script uses the following libraries:

RSQLite https://github.com/rstats-db/RSQLite

Hmisc http://biostat.mc.vanderbilt.edu/wiki/Main/Hmisc

dplyr https://github.com/hadley/dplyr

tidyr https://github.com/hadley/tidyr

ggplot2 http://ggplot2.org/

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

• participant_id
• trial
• 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
• alternative
• attribute
• duration: fixation duration in milliseconds
