Invitation to participate in a multilab Registered Replication Report

If you are a psychological researcher interested in helping with replication efforts in social psychology, we invite you to join our multilab replication project. The project has recently received in-principle acceptance at Advances in Methods and Practices in Psychological Science (AMPPS) and involves conducting two laboratory experiments testing ironic effects of thought suppression. Co-authorship will be granted to all contributing researchers (lab leaders/supervisors and experimenters) from labs that are able to collect a total post-exclusion sample size of at least 80 participants per experiment (160 in total) over a span of 12 months. Each experimental session should only last approx. 15 minutes, and will only require a computerized lab booth/room, a video recording device (e.g., iPhone), and a desk bell. More details such as the preregistration, experimental instructions/scripts, and the in-principle-accepted pre-data manuscript can be found at: Please read the protocol and consider carefully whether your laboratory can undertake the experiment (noting factors such as ethics application, timeline, equipment, and recruitment capacity), and complete data collection and collation accordingly.

For this project led by Deming (Adam) Wang at James Cook University Singapore, we currently have 27 laboratories that have expressed initial interest in participation, and we hope to recruit a total of 50 laboratories. This public call would therefore remain open until this number is achieved. We welcome labs from all countries, and we especially welcome laboratories from South America, Africa, and Asia. If you wish to test non-English speakers, please refer to the translation instructions outlined on page 9 of the pre-data manuscript via the aforementioned link. Assistance in embedding the translated stimuli and instruction slides into the Pavlovia program for Study 1 can be arranged. Note that author contributions need to be reported in accordance to the CRediT authorship system.

If you are interested or have any questions, please contact Dr Deming (Adam) Wang at: [email protected]
