Brief Statement of Original Result 2(valence: good or bad) x 2(category completion: possible or impossible) between-subjects design. When a series of tasks is unpleasant, completing a sub-category in the series is appealing, to make the series feel closer to completion.
Type of Replication Attempted Highly Direct Replication
Result Type Successful Replication
Difference? Same Direction, .00002
Number of Subjects 329
Number of Subjects in Original Study 127
Year in which Replication Attempt was Made 2014

Detailed Description of Method/Results Participants learned part of their job involved making several trips to Ecuador and Peru, and that they had already made 3 to Ecuador and 1 to Peru (counterbalanced). They were randomly assigned to further learn that they either enjoyed or did not enjoy the trip, and that they either had to make 4 trips to each country (category completion possible) or 10 (impossible). Lastly, they were asked to which country they would like to travel next.

The authors hypothesize completing a sub-category (e.g., all the Peru trips) fosters a greater feeling of progress through the super-ordinate task (i.e., all the business trips) than having progress in multiple sub-categories. Hence participants should prefer to travel to Ecuador (in the above example, to make 4 trips) when the trips are not enjoyable and when only 4 are required. When the trips are positive or completion of the category is impossible (the 10-trips conditions), this preference should be diminished. Both we and the authors find this interaction effect, with similar levels of significance.

We also included an attention check, asking participants how many trips they were required to take to Ecuador. Excluding the 46 (14%) who failed this check did not meaningfully affect the results, and in fact strengthened the critical interaction effect.

Figure 1 is a bar graph depicting the percentage of participants who chose to visit the more-visited country (e.g., Ecuador, above) in each condition for the original, replication, and replication excluding those who failed the attention check.
Any Known Methodological Differences
(between original and present study)?
To our knowledge, no methodological differences exist, aside from sample size: the original authors generously included their basic materials in an appendix and a detailed description for how they were modified in Study 3 in the study's method. We employed these materials to the best of our ability.
