This data set contains 1,035 observations of 18 variables from Experiment 1 of Kardas and O’Brien (2018). In this experiment, the authors randomly assigned participants to one of six between-subject conditions in a 3 (type of exposure: watch, read, think) × 2 (amount of exposure: low, high) design. The key dependent variable is perceived ability, operationalized as how much participants believed they could pull off a “tablecloth trick” (removing the tablecloth from a table without upsetting the dishes on the table) based on the type of training they received.
Format
A data frame with 1035 rows and 18 variables.
- p_number
participant ID
- heard_before
Whether the participant knows what “the tablecloth trick” was before the beginning of the study with levels 1 = Yes and 2 = No. All participants completed the study but participants who indicated they did not know were excluded from the analysis.
- type_of_info
Experimental condition for type of exposure with levels 1 = Watching, 2 = Reading and 3 = Control.
- amt_of_info
Experimental condition for amount of exposure with levels 1 = Low Exposure and 2 = High Exposure.
- perceived_ability
Dependent variable; “You jump in and give the trick ONE SHOT yourself. What do you feel are the chances that you’d successfully pull it off?” on a 1 to 7 scale where 1 = I feel there’s no chance at all I’d succeed on this attempt, 7 = I feel I’d definitely succeed without a doubt on this attempt.
- manipulation_check
Manipulation check for amount of information; “About how much of this ‘more information’ do you feel you were given?” on a 1 to 7 scale where 1 = very little/went by quickly, 7 = a lot/displayed for a while.
- technical_difficulties
Whether participants had any technical difficulties with levels 0 = No and 1 = Yes.
- technical_difficulties_description
Free text describing the technical difficulty.
- gender
Participant’s gender with levels 1 = Male, 2 = Female and 3 = Other.
- ethnic_1
Participant identified as Black with levels 0 = No, 1 = Yes.
- ethnic_2
Participant identified as Hispanic with levels 0 = No, 1 = Yes.
- ethnic_3
Participant identified as Asian with levels 0 = No, 1 = Yes.
- ethnic_4
Participant identified as American Indian with levels 0 = No, 1 = Yes.
- ethnic_5
Participant identified as White with levels 0 = No, 1 = Yes.
- ethnic_6
Participant identified as Other with levels 0 = No, 1 = Yes.
- age
Participant’s age in years.
- tried_before
Whether participants had ever previously attempted a tablecloth trick in their everyday lives with levels 1 = Yes and 2 = No.
- fail_ac
Whether a participant failed an attention check with levels 0 = did not fail any attention checks and 1 = failed one or more attention checks.
