Format

An object of class tbl_df (inherits from tbl, data.frame) with 128 rows and 3 columns.

An object of class tbl_df (inherits from tbl, data.frame) with 170 rows and 3 columns.

An object of class tbl_df (inherits from tbl, data.frame) with 1024 rows and 4 columns.

An object of class tbl_df (inherits from tbl, data.frame) with 1536 rows and 5 columns.

Details

Each data frame contains a subset of the following 11 variables:

stim_id

Unique identifier of the stimulus.

statement

The statement.

actual_truth

Actual truth or falsity of the statement.

choice

Category number; allows for more than one correct categorization.

category

Name of category.

list_id

Unique identifier of stimulus presentation list.

repetition

Whether the statement was repeated or novel.

interval

Interval (phase) in which the truth-rating was performed (immediate = 1, 1 day = 2, 1 week = 3, 1 month = 4).

phase_id

Phase (1-4) in which the stimulus will be presented.

task

Which task the stimulus is presented in (categorize or rate truth).

task_id

Unique identifier of the task/stimulus combination.

The stimulus_materials data frame lists all 128 trivia statements used in the study. These statements were adapted from \insertCiteNadarevic2014;textualtruthiness and \insertCiteDekeersmaecker2019;textualtruthiness, who in turn adapted their materials from those original compiled by \insertCiteUnkelbach_Rom_2017;textualtruthiness. Each stimulus is given a unique identifier, stim_id, that appears across related tables.

The stimulus_categories data frame gives information about which category each stimulus statement belongs to. Note that each statement can belong to more than one category simultaneously.

The stimulus_conditions data frame provides a 'lookup' table that associates each stimulus (stim_id) from each presentation list (list_id) with its experimental conditions (repetition, and interval).

There were eight separate presentation lists used in the study for counterbalancing purposes. These lists are provided in the presentation_lists data frame.
