GAME-CHANGING

Testable helps you create a wide range of behavioral experiments and surveys in the simplest and fastest way. You fill in a spreadsheet with information on trials and questions, upload the stimuli (if needed), and hocus-pocus, the study is up and ready to run! Testable offers a unique combination of power, flexibility, and speed.

CONVENIENCE

Your behavioral experiments and surveys will be created, stored, and managed in the cloud, accessible at a unique address by any major browser. You don't need to install any software and you can easily share your studies with participants and other researchers, without worrying about different operating systems or other compatibility issues. Everyone will see an identical version of your study on any machine. A browser is all you need.

STRONG COMMUNITY

We have a 2000+ friendly community of researchers using Testable for their lab-based and online studies. You can ask questions, get tips, or offer advice on issues related to Testable and experimental design. Most importantly, researchers can instantly make their experiments available to other researchers. It is our contribution to transparency and replicability in science. No other software or platform offers you comparable sharing options!

BETTER DATA

For data collection, use Testable Minds - the next-generation subject pool for behavioral science. Our participants are diverse, verified, and reliable, with 85% coming from countries where English is first language. On Testable Minds you can post studies created with our software or with any other software (e.g. Qualtrics). All you need to do is sign in to Testable, access Testable Minds from the left menu, and post your study to our subject pool.

Covers a wide range of experiments
with many ready-made templates

Chances are you don't need anything else. But write to us if you do.

Images, sounds, videos, words

Switching between them is as easy as specifying the file extension - literally. All major image, video and sound files supported.

Multiple response options

Click stimuli, click buttons, press specific keys, or type text. The choice is yours.

Various presentation modes

Simultaneous or sequential presentation of stimuli. With or without a target image. Masked or unmasked. With full control over presentation times, ITI, ISI, etc.

Many other features

Randomisation within and between blocks, feedback for incorrect trials, display average correct score, generate random code at the end. And working on many others.

Ideal for online experiments
and instant sharing

Make your experiments available indefinitely at a permanent link with the "lock" option. Perfect for demonstration to students, reviewers and other researchers (just include the link in your paper).

How to use it

Sophisticated platform, simple interface.

TESTABLE

Simple interface

After you sign up for an account and login, you will get access to a profile dashboard and a projects dashboard. In the profile dashboard you can manage your account details. The projects dashboard is where the action is.

Examples

These are only four examples of the kind of tests you can design with Testable. The whole range is much larger. In fact, we believe Testable can cover the vast majority of the standard behavioral experiments.

TESTABLE

Picture Naming Test

Participants identify pictures of famous people.

TESTABLE

Matching Test

This is a simple test in which participants have to select the test image that best matches the target.

Stroop Test

A very short version of the famous Stroop test.

Face Detection Test

Participants have to detect faces from minimal information.

JEREMY WILMER, WELLESLEY COLLEGE

Power, flexibility, and ease-of-use

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.

BRAD DUCHAINE, DARTMOUTH COLLEGE

Everyone in my lab uses it

Everyone in my lab, from undergraduates to postdocs, uses Testable to get experiments running online quickly and reliably. It's a great platform!

TIRTA SUSILO, VICTORIA UNIVERSITY OF WELLINGTON

Seamless collaboration and exact replication

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!

KIRSTEN DALRYMPLE, UNIVERSITY OF MINNESOTA

Made my life so much easier!

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.
