[CogSci] Call for unpublished data: Meta-Analysis on Trust Game

[Fatemeh Asgharian]

Dear Colleagues,

We are conducting a comprehensive meta-analysis on the trust game
(pre-registration
link <https://osf.io/67u53/>). We are seeking unpublished manuscripts,
preprints, papers in press, theses, or any other form of grey literature or
unpublished data (e.g., working papers, conference papers/posters, studies
that measured the construct but did not report it etc.) related to trust
game experiments.
Specifically, we request the following information (if available):
1. Trust and reciprocity decisions (means and SDs) for all rounds
2. Specific trust game design (e.g., one-shot, repeated, with/without role
reversal)
3. Sample size and demographics (number of participants, gender
distribution, age)
4. Currency used and endowment amounts for sender and receiver (if any)
5. Average sent ratio and average returned ratio
6. Number of trials
7. Anonymity conditions (anonymous, double-blind)
8. What type of participants were included in your study? (Were they
students, the general population, or any other specific demographic groups?)
9. Could you provide details about your methodology?
    a) Did you use the strategy method?
    b) Did participants play both roles (trustor and trustee)?
    c) Did participants interact with real partners or computerized agents?
10. Were there a risk, lottery, chance, nature, etc. conditions in your
study?
11. What were the specific experimental conditions?
    a) Was there any form of deception (misleading information about study
design and experiments stated to participants) used?
    b) Were participants paid money based on their performance and
decisions?
12. a) In which country was the study conducted?
    b) Were the experiments conducted on online platforms, in the lab, or
the field?
13. When was the study conducted? If available, could you provide the dates
when:
    a) Which year was the data collection done? Or
    b) The paper was first submitted for publication?
14. Are there any additional notes or relevant information about your study
that you think might be helpful for our meta-analysis? This could include
unique features of your study design, challenges encountered, or any other
aspects you believe are important to consider.
It would be greatly appreciated if you could send the corresponding data or
studies to this email address: trust.meta.analysis at gmail.com
Please feel free to reach out with any questions or uncertainties.  The
study will be able to include data submitted by September 2024.

Thank you very much for your support.
Best regards,
