This is an anonymized version of the pre-registration.  It was created by the author(s) to use during peer-review.
A non-anonymized version (containing author names) should be made available by the authors when the work it supports is made public.

1) Have any data been collected for this study already?
No, no data have been collected for this study yet.

2) What's the main question being asked or hypothesis being tested in this study?
Hypothesis 1: Group performance increases average workgroup member status.

Hypothesis 2: The relationship between group performance and average group member status is mediated by solidarity with the group.

3) Describe the key dependent variable(s) specifying how they will be measured.
The major DV is status. We will measure overall status, and the average scores of three team members will be used in analysis.

1. Overall perceived status (adapted from Flynn & Brockner, 2003; see also Anderson, John, Keltner, & Kring, 2001) (1-5 scale)
-How well respected was this team member?
-How valuable was this team member’s contributions in teamwork?
-How much influence did this team member exert over decisions in teamwork?

Repeat the same measures for team member 2 and 3.

4) How many and which conditions will participants be assigned to?
All participants will be randomly assigned into a team of 4 members to complete a team task.

5) Specify exactly which analyses you will conduct to examine the main question/hypothesis.
We will analyze the correlation between team performance and average status conferrals to test our hypothesis. We'll also analyze if the correlation changes depending on the specific metrics of team performance, which include self-reported team performance, objective team performance (i.e., the height of a tower in the Marshmallow Challenge) and the relative team ranks within each session. It could be that participants are more sensitive to their team's relative ranks within each session than the absolute performance among all teams.

We'll also analyze if the relationship between team performance and status conferrals is mediated by perceived solidarity with the team.

6) Describe exactly how outliers will be defined and handled, and your precise rule(s) for excluding observations.
There is no exclusion in this study.

7) How many observations will be collected or what will determine sample size?
No need to justify decision, but be precise about exactly how the number will be determined.

We plan to recruit N=160 people in total. Participants will be randomly assigned into a team of 4, and we plan to run multiple sessions with around 10 teams in each session. The actual number of participants as well as the number of sessions may change depending on how many participants actually show up at each session.

8) Anything else you would like to pre-register?
(e.g., secondary analyses, variables collected for exploratory purposes, unusual analyses planned?)

We'll measure self-reported team performance, team ranks within each session and absolute team performance (i.e., length of a tower).

We'll also measure perceived solidarity with the team.

Participants' basic demographic information (e.g., age, gender and ethnicity) will also be collected. We'll also ask if participants completed similar task to the Marshmallow challenge before.
