• MediaLab now produces native SPSS (.sav) data files. This means importing is no longer necessary.
   
• Complex skip patterns. Now you can base skips on any prior response, or even combinations of prior responses.
   
• Calculate scores and other variables while a session is running--present them on screen as stimuli, use them in skip patterns, or in post-session reports.
   
• Create and optionally print summary reports immediately following the experimental session. Create graphs, scale scores, anything you want!
   
• Create your own custom questionnaire item types using Visual Basic, Visual C++ or other development platforms using the new MediaLab ActiveX control. Re-use your custom item type in other experiments or share it with others! Samples to guide you through it!
   
• Enhanced video support for MPEG and AVI video formats.
   
• Support for the newest QuickTime and RealPlayer video formats (Win98/ME/2000/XP only).
   
• Powerful Ranking feature now allows your subjects to drag and drop items to sort them by any criterion you like--includes an optional RT for each item.
   
• Measure voice reaction times
   
• Record spoken responses saved as individual sound files.
   
• Play back spoken responses as subsequent stimuli
   
• Communicate with external equipment or other computers to indicate the start of a trial for synchronization (e.g., for use with psychophys equipment).
   
• Receive input from external devices such as response boxes.
   
• Use percentage values for top, left, width and height parameters. No more need to use annoying pixel values.
   
• Individually Position and Resize Response Buttons.
   
• Improved foreign character support
   
• Require a correct response to scale items before a subject can continue.
   
• 100% compatible with experiments designed in all previous versions of MediaLab
   
• New samples that illustrate all the new features!
   
• Improved experiment editor.
   
• Navigation buttons are now an option for HTML items to enable subjects to browse more freely through local or web-based content (e.g., forward, backward, home).
   
• Option now to define the RT of open-ended questions (e.g., essays, fill-in-the- blanks) as the first or last key press.
   
• Assign a time limit to an entire questionnaire now with a countdown clock to let subjects know how much time they have left.
   
• Create time-stamps (12:32:23pm) when you want to track activity in real time.
   
• More secret keys. e.g., experimenter can now go back even when it's not offered an option as well as enter response values not offered on screen.
   
• To reduce recoding, you can now specify alternate data file values for response options (e.g., have -5 written to the data file for a given response)
   
• Change the missing data value to whatever you like -- not forced to use 99 any more.
   
• Can now use negative values in range function for fill in the blanks
   
• Define the minimum and maximum number of responses allowed for a multiple response items.
   
• <Specify> function now works for thought ratings to allow for open ended responses.
   
• Minimum item durations--as an alternative to defining an exact duration for an item, you can now specify a minimum time for an item.
   
• Option to lock the Clear Data button so that it can not be accidentally hit.
   
• Many other general tweaks and fixes
