If
you are already a MediaLab user and are interested in upgrading to MediaLab
v2004, see What's New in
MediaLab v2004. If you would like to upgrade or
purchase MediaLab now, please visit our order page for details
on how to get new or upgraded licenses.
If you're new to MediaLab, this page provides
an overview of the program and a summary of features (old and new). If
you would like more details about MediaLab, you can preview MediaLab's
user-friendly
manual.

MediaLab Research Software was designed as a
user-friendly tool to help both technologically savvy and technologically challenged
researchers with their creation of powerful computerized experiments. Designed
specifically for the Windows environment, MediaLab combines smart experimental design
features with the capabilities of current Pentium class PC technology.
The three highest priorities in designing
MediaLab were to provide researchers with
- a highly intuitive and user-friendly
environment in which to create experiments
- a high degree of flexibility with respect to experimental design
- software that would allow them to fully exploit the power of
current pc technology
If you would like to see some of the initial
reviews that MediaLab received, see our reviews page.

MediaLab allows you to specify as many
experimental conditions as you like. Traditionally, general purpose programs have had
limited flexibility when it comes to experimental design. With MediaLab,
participants can be administered different stimuli and different dependent measures and in
different orders depending on the experimental condition to which they are assigned.
MediaLab allows for a wide variety of input
responses from human subjects including multiple choice responses, fill-in-the-blanks,
essay-type open ended responses, thought and recall listings, and even ratings of one's
own open-ended responses. MediaLab optionally assesses the reaction times for each
response.
When the experiment is finished, MediaLab
writes the data to an easy to analyze ASCII text file. Importantly, MediaLab writes
the data file in a way that its format is constant no matter what condition the
participant was in. This means one data file for all subjects in all conditions with
one single set of variable definitions. MediaLab also automatically creates variable
definitions so that you can instantly read the data into Excel or SPSS and analyze it
immediately. Also provided is a utility to easily merge the data files collected on
multiple computers.
MediaLab also allows you present a wide array
of stimuli from basic and fully-formatted Word, WordPerfect, HTML, and PowerPoint Shows to
multi-media files such as audio, video and image files. If MediaLab can not perform
a specific task, it will branch off to run an independent program of your own creation
during an experiment, and then return to where it left off.
MediaLab also comes with extensive help
files, a complete 93-page manual and an on-line tutorial with sample files. However,
if creating your first experiment seems a little intimidating, see our Services page for information on how we can help you out.

- Define as many experimental conditions
as you like (great for factorial designs)
- Flexible randomization features
- Randomize items within a single group
- Randomize the order that groups of items
are presented
- Randomization routines at both the
experiment level and within questionnaires
- Embed your own or third-party programs
(DOS, Windows 3.1 and Windows 95 and later) within an experiment or
questionnaire
- Run DirectRT or Inquisit sessions from
within your MediaLab experiment.
- Create multiple custom preference
settings with choices of fonts and display colours
- Context sensitive help such that
pressing F1 at any time will help you with what you are currently
doing
- Option of on-the-fly editing of Word and
WordPerfect documents-edit them as you run through your experiment.
- Resolution independent-compatible with
screen displays from 640x480 to 1600x1200
- Easy-to-use intuitive interface--no
programming code necessary
- Now compatible with non-english fonts
(e.g., Japanese, Chinese, Arabic)
- Customize all messages and/or translate
into any language
- Optionally run experiments from a CD-ROM
or Server on LAN
|

- Scale responses with up to 12 closed
ended responses
- Multiple response (select all that
apply) responses
- Fill-in-the blank responses (free or
restricted)
- Essay-type responses
- Thought listings and recall listings
- Have subjects rate their own
thought-listing responses on any dimension
- Easy text-based instructions for any
question
- Present html pages with active
hyperlinks. MediaLab uses the Intenet Explorer browsing engine so you
can display anything that Explorer can.
- Track browsing behaviour as subjects
navigate through local html files or the world wide web. Track every
link the subject follows and record when they arrived and how long
they stayed.
- Easily present Microsoft Word or any
other OLE compatible documents for more elaborate formatting
- Easily embed Microsoft PowerPoint shows
within your experiment or questionnaire(s)
- Gather on-line continuous rating data
during audio and video clips.
- Skip pattern capability when a
particular closed ended response is given
- Questionnaire items can be omitted in
specified conditions
- Easily modify and re-use your
questionnaires in other experiments
- Option of self-paced or time-limited
responses
- Allow subjects to return to previous
questions if necessary
- Embed subjects' responses in subsequent
question wordings
- Create multiple style configurations
(e.g., colours and fonts) for use within the same experiment or
questionnaire.

- Present graphics (.bmp, .jpg, and .gif)
- Present sound files (.wav, .mp3)
- Present video (.avi, .mpg, .mov)
- Present combinations of graphics, sound,
video and questionnaire items

other browser compatible files
- Optional parameters allow you to set the
screen location of images and movies as well as set the size of video

- Writes data to an easy-to-analyze ASCII
file
- Your choice of which variables to write
to the data file

can be imported straight into Excel (up to 255 variables) or SPSS
(unlimited variables). Variable definitions are written automatically,
so you can start analyzing your results immediately.
- Two sets of data files are produced, one
organized by questionnaires, the other by variable names.

For most uses, MediaLab will run perfectly well on any Pentium system (or equivalent), running Windows 95, 98, ME, NT,
2000 or XP. At least 32 Mb of RAM is recommended. If video is going to be used frequently (e.g., MPG, AVI, MOV), then additional RAM is advisable though not necessary. Video cards with at least 2 Mb of video memory also are recommended. Unlike earlier versions, MediaLab no longer requires that you have Microsoft Access installed.
It is recommended that you also install Microsoft Office on all machines that will be running MediaLab, especially Word and PowerPoint. These programs allow MediaLab to present documents fully formatted by Word and slide shows prepared in PowerPoint. Although MediaLab will work fine without them, these programs perform cooperatively with MediaLab to produce some very impressive functionality. Also Microsoft's Internet Explorer version 4 or later is required in order for MediaLab to present HTML formatted pages (whether stored locally or on the internet). Finally, it is necessary to have a spreadsheet application (e.g., Excel, Lotus, Quattro, SPSS) installed in order to view the data files produced by MediaLab.
If you want to do traditional reaction time
studies...

Although MediaLab easily allows you to assess
reaction/response times with a high-resolution (i.e., < 1 ms) timer, it does so in the
traditional Windows environment which is not ideal for experiments that demand extreme
timing precision. For the purpose of conducting studies that require highly accurate
response times to visual stimuli (e.g., priming studies), we have now
released DirectRT, which provides a means to present images,
text, sound and video and to assess
reaction times with an exceptionally high degree of precision. The advantage of
DirectRT is that it takes advantage of Microsoft's DirectX technology and so requires no
special hardware in order to get very precise display times and high quality RT's (even
with a standard keyboard, error is remarkably low). DirectRT can be used on its own
but also works great in conjunction with MediaLab. See our DirectRT page for more details.
