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.
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.
