Testable helps you create a wide range of behavioural experiments and surveys in the simplest and fastest way. You kickstart the experiment using our natural language form, upload your stimuli (if any) and then use a visual editor to make any tweaks to your design. Your study can be up and ready to run in minutes! That's how Testable offers a unique combination of power, flexibility, and speed.
Your projects will be created, managed and safely stored in the cloud. Testable is designed to just work, without the hassle. Participants can access your studies using a unique link and you and your participants won't have to worry about downloading any software or compatibility issues. A browser is all that is needed.
We have thousands of committed researchers using Testable for their lab-based and online studies, willing to share their experiments with the scientific community. Our Library contains published and unpublished experiments from our users, instantly available to other researchers who can request to use them in their own research. It is our contribution to transparency and replicability in science.
To offer you the best participant data for your experiments, we have built Testable Minds - the next-generation subject pool for behavioral science. Our 30k+ participants are diverse, verified, and reliable, with 85% coming from countries where English is first language. On Testable Minds you can post studies created in Testable or with any other software (e.g. Qualtrics). You can access Testable Minds from your dashboard once you signed up.
You can choose between images, videos, text and audio stimuli. Freely switch between them from trial to trial as your experiment requires it.
You can allow your participants to respond with anything available to them at a computer. They can use their mouse, keyboard, press buttons on screen and even use their voice!
Easily set up your trials by choosing between sequential or simultaneous stimulus presentation, adding masks, targets, fixation crosses, defining feedback and controlling all key timings such as ITI, ISI, the response window or presentation times.
Take full control of randomisation within and between blocks, use logic statements to create non-linear experiments and create between-subject experiments that takes care of the group allocation for you.
New experiments and surveys may be created in minutes using our natural language form. Simply describe the type of experiment you would like to create and voilà, instantly up and running. Often, there is nothing else to do but upload your stimuli and refer to them in the trial file. No programming, no complicated graphical user interface.
Testable experiments and surveys are built from spreadsheets - we call them trial files. All experimental parameters, related to stimuli presentation, times, response options and others, are neatly organised in a spreadsheet. That makes it incredibly easy to make any changes. You can edit trial files offline (using Excel or Google Sheets) or online with our visual editor.
Creating and editing experiments has never been easier than with our visual editor. Specify all important information about your trials in our smart and responsive trial sheet. You can preview your experiment trial-by-trial using our built-in visualizer and see what your participants would see in real time. No other tool is faster or easier to use.
From creating your first experiment to building a complex study for your final year project or your next Science paper, we are there to help. Our rich knowledge base offers you step-by-step guides that will allow you to quickly create even the most advanced experiments in Testable. There are also video tutorials and weekly live webinars to make you an expert in no time and help you along the way should you ever get stuck.
Here are only three examples of the kind of tests you can design with Testable. But you can also create your own of browse our ever-growing library of ready-made tests.
A brilliant combination of power, flexibility, and ease-of-use, Testable democratizes the process of online experiment-creation by removing, completely, the need to write a single line of computer code...in so doing, it greatly accelerates the idea-to-implementation process for both research and teaching applications.
Everyone in my lab, from undergraduates to postdocs, uses Testable to get experiments running online quickly and reliably. It's a great platform!
Testable provides a state-of-the-art platform for researchers, teachers, and students in behavioural and cognitive sciences to focus on what really matters: experimental design and data collection. Anybody who knows how to operate a spreadsheet software can use Testable to create and run experiments on the web and in the lab – without the need to code! Not only that, Testable allows easy sharing of experiments for seamless collaboration and exact replication. My students and I are avid users of Testable. Highly recommended!
I can focus on test design and data collection rather than trying to figure out how to program my experiments. I study rare populations that are spread out around the world, and now I can collect data online by having participants take tests from home and have the results appear in my secure account at the lab. I can also share the tasks that I designed with other researchers and collaborators without the need for them to download or purchase special software. Finally, it’s a great teaching tool because my students can use it easily to design their own experiments.
We are a small group of academics and science enthusiasts, backed up by a strong team of academic advisors.
