Research Participant Platforms


Prolific is a platform that connects researchers to their target participant pool and is based in the UK.  In order to use Prolific as a vendor the PI or research staff must first contact Prolific’s customer service at to obtain an invoice for study costs that includes the required tax language for UCLA.  Once you receive this invoice, please submit it as per standard practice to  The Business Office will process your invoice and submit for payment. We will provide you with the purchase order number related to your request that you can use to follow up with Prolific and confirm the credit to your account. Payments to Prolific are made via wire transfer.  Please note that international transfers do not settle immediately due to varying time zones and banking standards abroad.  Total processing time from the time we receive your request to the time that a wire transfer settles is about 7-10 business days.  Once the wire transfer settles your Prolific account is funded with the amount specified on your request.  Please account for this timing when planning your studies. 

Wire Transfer Minimums

The University wire transfer minimum is $200.  If your request is for less than $200 we will group it together with other departmental wire requests to the same vendor.  This may delay the processing time since processing will depend on whether we have other requests to use for this grouping. 

Mturk and CloudResearch

Amazon Mechanical Turk (MTurk) and CloudResearch provide platforms aimed at recruiting study participants and are both based in the U.S.  Researchers interested in MTurk or CloudResearch, would need to complete the request form and provide login credentials to the account that will be funded.  The request form should be emailed directly to the PI’s assigned fund managers and must be either signed by the PI of the fund being charged or have the PI copied on the email request, per our standard departmental ordering procedures. 

Mturk and CloudResearch accounts are funded using departmental pre-loaded credit cards. The fund manager will confirm once the transaction is completed. Requests typically take 3-5 business days to fully settle from the time that the request is received. Please account for this in planning your studies. Please use the Amazon Mturk and CloudResearch Request Form for this type of request.
