Inquisit 3 Web
Inquisit 3 Web enables you to administer studies over the web so that subjects can
contribute psychological data from their homes, dorms, offices, and internet cafes. With
just a few mouse clicks, you can publish your study online and begin collecting data over the web.
Reach more diverse subject populations
Inquisit 3 Web expands your subject pool by allowing participants to perform psychological tests and experiment at a time and location of
their convenience. Web studies are a great option for reaching populations who cannot come into the lab due to
geographic location, scheduling conflicts, or anxiety. (Note - Inquisit currently runs on Windows
only. It does not yet run on Macs.)
Unlimited numbers of participants
With a single Inquisit 3 web license, you can publish a study online and gather data from an
unlimited number of participants simultaneously or in sequence. Gather as much data as you'd like -
there are no charges per data file. This makes Inquisit very cost effective for both internet research
and mass testing sessions in class rooms and large labs.
Point and click web deployment
Inquisit 3 Web includes an easy to use control panel for deploying experiments online. No
knowledge of web server administration is necessary. The web license includes free hosting on
millisecond.com, or you can optionally host experiments on your own web server.
To access your data,
simply login to you millisecond account, browse to your data files, and select which files to download.
The data are saved as tab-delimited text that can be loaded into any analysis package (e.g., SPSS, Excel).
How accurate is timing over the web?
When a participant browses to the experiment launch page and clicks "Start", the engine is downloaded and runs
locally on the participant's machine, where it has access to all of the high-peformance native Windows components
it needs to achieve millisecond precision timing. In fact, Inquisit 3 Web uses exactly the same powerful and fast
engine that Inquisit 3 desktop uses. The engine is only 700k compressed (about the size of an iPhone picture), so it take just a few
seconds to download. We've wrapped the engine in several web technologies that provide a smooth download experience
across a wide variety of web browsers.
Variability in client computers
One consequence of running web experiments is that web client PCs vary in processing speed.
Inquisit is a lightweight, efficient engine that performs well on even the slowest
computers still in use today.
Besides processing speed, computer graphic displays may vary in both display resolution and vertical
refresh rate (i.e., how quickly the screen repaints itself). To control for different display sizes,
Inquisit allows you to define the size and layout of visual stimuli as a percentage of the screen size,
so the display scales appropriately given the size of the monitor. Although Inquisit cannot
control the vertical refresh rate of the monitor, Inquisit can detect the parameters of the display
system and be configured to either screen participants whose hardware doesn't meet standards, or record
the refresh rate to the data file so it can be treated as an independent variable.
Where can I try an Inquisit 3 Web experiment?
To see what it's like to participate in an Inquisit web experiment, we have dozens of measures available online in the Millisecond
task library. Just click
the measure you are interested in, and then click the "View Demo" link on the home
page for that measure. For example, you can test our IAT scripts by clicking any of the "View Demo" links on our
Where can I get Inquisit 3 Web?
The first step is to download the free trial of Inquisit 3 Desktop from our download
page. Inquisit 3 Desktop provides the tools for editing, testing, and debugging your
experiment scripts. You can download scripts from our task library or create your own.
Once your script is running, you can purchase an Inquisit 3 license, login to your account,
and use the control panel to upload the script and any required media (e.g., pictures, sounds,
videos). Your experiment will be published online and is ready for data collection.
The rest of the tools for
Inquisit 3 Web Edition are offered as services on our web site, so there is nothing
more you need to download. To see Inquisit 3 Web Edition in action, check out our demos.
Can I evaluate Inquisit 3 Web?
Follow this link for instructions on evaluating Inquisit 3 Web. Note that without a license, you can
run experiments online but the data will not be saved. You can use the free trial of Inquisit 3 Desktop to see how
data are saved since the format is identical to that of Inquisit 3 Web.
