|Reference to Original Report of Finding|
|Title||Glucose promotes self-control processes|
|If the original article contained multiple experiments, which one did you attempt to replicate? e.g., you might respond 'Study 1' or 'Experiment 4'.||Experiment 8|
|Link to PDF of Original Report|
|Brief Statement of Original Result||Gailliot et al (2007) found that thinking of mortality (cf. dental pain) depletes self-control, leading to poorer word-puzzle performance, but this deficit was eliminated by consuming a glucose drink instead of a placebo.|
|Type of Replication Attempted||Highly Direct Replication|
|Result Type||Successful Replication|
|Difference?||Same Direction, .03|
|Number of Subjects||58|
|Number of Subjects in Original Study||73|
|Year in which Replication Attempt was Made||2012|

|Detailed Description of Method/Results||
Student subjects were randomly assigned to consume either a placebo (lemonade made with water and lemons, plus Splenda), or lemonade plus 140 calories of glucose instead of Splenda. Both drinks were 14 oz.
They then completed two measures of liking for the drink, followed by filler questionnaires and a crossword for 12 minutes to allow absorption.
Next they wrote about one of two topics for 5 min. For mortality salience they wrote about what happens to their body after death, and their emotions. For dental salience they wrote about how their body reacts to dental pain, and their emotions.
They were then given a sheet with 20 word fragments (words were selected randomly from the dictionary) allowed 10 min to solve them. (e.g. ___ ATULA). They were scored for the number of word fragments left uncompleted, out of 20.
Finally they completed the Marlowe-Crowne Social Desirability Scale, and estimated how many calories there were in the drink they had consumed.
Mean uncompleted words (SD) (n) were:
- Dental salience 12.21 (2.19) (14)
- Mortality salience 14.72 (3.43) (18)
- Dental salience 13.08 (2.87) (12)
- Mortality salience 13.07 (2.70) (14)
A 2x2 independent groups ANOVA showed no significant effect of salience, F(1, 54) = 2.67), p = .11; nor drink, F(1, 54) = .26; nor their interaction, F(1, 54) = 2.72, p = .10.
However an independent groups t-test indicated that in the placebo group the number of uncompleted words increased from the dental to the mortality salience condition, t(29)= 2.28, p =.03. This indicates decreased self-control due to mortality salience, as reported in the target article.
Our results for the glucose group agree with the target article in showing no difference between dental and mortality salience conditions.
No effects were seen from the rated taste of drink, social desirability, rated number of calories, or gender.
|Any Known Methodological Differences |
(between original and present study)?
|The time allowed for the word puzzle task was not specified in the original article, so we imposed a ten minute limit; this proved adequate. For the lemonade we allowed 1 sliced lemon per 56oz water, plus a packet of Splenda in the placebo condition.|
