Invitation to Participate in a Multilab Registered Replication Report

Logo for the journal AMPPS

Psychological researchers interested in helping with replication efforts in social psychology are invited to join a multilab replication project at James Cook University Singapore. The project will be published in the APS journal Advances in Methods and Practices in Psychological Science.

The project involves conducting two laboratory experiments testing ironic effects of thought suppression. Co-authorship will be granted to contributing researchers 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 last approximately 15 minutes and will 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.

The project is led by Deming (Adam) Wang at James Cook University Singapore. As of mid-December, 2022, 27 laboratories have expressed initial interest in participation, and the hope is to recruit a total of 50 laboratories. This public call will remain open until this number is achieved. The project team welcomes labs from all countries, especially 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.
