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

  1. a highly intuitive and user-friendly environment in which to create experiments
  2. a high degree of flexibility with respect to experimental design 
  3. 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

flex.gif (2112 bytes)

  • 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.

multi.gif (1542 bytes)

  • 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
  • Present html, flash, java, asp and any 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 clips all the way up to full screen

data.gif (1240 bytes)

  • Writes data to an easy-to-analyze ASCII file
  • Your choice of which variables to write to the data file
  • Writes all data into a single file that 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.
  • Includes a utility to easily merge data files collected on different computers
  • Optionally write reaction time for any response to the data file
  • Optionally write data from multiple computers to a single folder on your network

system.gif (1850 bytes)

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.
