We recently launched a ground-breaking feature that helps protect Mechanical Turk worker identities. It has been reported in the literature that Mechanical Turk Worker IDs can be used to identify the worker. This is because Amazon uses the same value for both the Worker ID on Mechanical Turk and elsewhere on Amazon properties like Amazon.com product reviews.
Block Duplicate IP Addresses
Our most popular feature request has been to allow the blocking of multiple workers from the same IP address.
You can now run your Amazon Mechanical Turk studies at Hyper speeds. We worked hard to make the experience identical to our classic MicroBatch option so that you simply launch your study and TurkPrime does all the heavy lifting for you.
TurkPrime can now automatically add Worker ID, HIT ID, and Assignment ID to data files, including CSV and SPSS files. These variables can be very useful when you want to match Workers across multiple data files. For example, in longitudinal studies, researchers typically ask Workers to provide their Worker IDs in order to pair responses collected at different points in time.
TurkPrime has just released a Copy feature which makes duplicating past TurkPrime HITs simple and fast.
To copy the settings from an old survey to a new one, follow these simple steps:
We have deployed a micro-batching feature which allows Requesters to break up their studies into smaller segments, and to include time intervals between the segments. We developed this feature to increase sample representation. This feature can also save 50% in MTurk fees.
Run Qualtrics Surveys on MTurk using TurkPrime
Running Qualtrics surveys on TurkPrime streamlines several major pain-points researchers using MTurk have dealt with:
Suppose you're running a Mechanical Turk survey and need to exclude workers who took a previous survey. How can you quickly set this up.
Some of the currently used solutions require following multiple steps to set things up and are not turnkey solutions and others require Workers to enter their Worker ID, which may self-filter workers and limit the number of workers taking your survey.
Suppose you need to run a HIT with 1000 Workers. Or a HIT that is only open to Workers who have an approval Rating of 95% or more and have completed 500 HITs or more. Although when you launched your HIT the MTurk Workers arrived at a nice pace, over time, the pace has slowed to a trickle such that your HIT will never complete.
Suppose you need to run a group of HITs open only to participants who are women under 50. You previously ran a HIT and know the Worker IDs that you want to reach, but have no way to email them and limit your survey to only them. How can you proceed?
