What's new in Portable Brain Workshop 4.8

Sep 30, 2010
  • Changed config.ini file format. Existing config.ini files will be renamed and replaced. Users will have to migrate their customizations manually.
  • Added Multi-stim modes, whereby objects appear in two to four places
  • in the 3x3 grid at the same time. Objects can be differentiated either by image or by color.
  • Added Crab modes. In crab modes, you have to reverse every N stimuli when matching, so that in 3-back, if the stimuli you saw were the first line below, then you would be matching them against the second line
  • ull support for multiple users and/or profiles. This lets you
  • easily keep separate statistics for different settings (for example,
  • with different timings or with JAEGGI_SCORING in the config file) or
  • for different users.
  • Added an "interference" setting, whereby a certain percentage of the time Brain Workshop will generate trials designed to be particularly tricky, such as by making the current stimulus match the stimulus n-1), (n+1), or (2n) trials ago, or (in multi-stim mode) by swapping the positions of the stimuli (n) trials ago.
  • New mode-, sound-, and user-selection screens.
  • Changed how often matches are generated for modes other than Dual N-back.
  • Made Brain Workshop ask for donations, by default every 100 sessions. You should do as the program asks. (This behavior can be changed in the config.ini file.)
  • Trial-by-trial session data are now recorded to disk in Python's pickle format in the USERNAME-sessions.dat files.
  • Changed how scores are calculated in graphing; the percentage of items correct now affects the exact score in addition to the N-back level.
  • All of the music files and some of the other media files have been removed for copyright reasons and replaced with free alternatives.

New in Portable Brain Workshop 4.7 (Sep 30, 2010)

  • Added Dual Audio n-back modes. Go to the Sound Selection screen to choose the sound set and channel (left, right, center) for each
  • sound stimulus.
  • Number of trials per session now increases automatically with higher n-back levels. The calculation can be adjusted from the config file.
  • Timing resolution has been increased to 0.1 seconds, with a maximum speed of 0.3 seconds per trial.
  • Toggling Manual Mode no longer reverts to default settings.
  • Title screen graphic is now colored inversely when a black background is
  • selected.
  • Stats file may be specified on the command line with --statsfile, complementing the --configfile command line parameter.
  • Comments may be added to the stats file on separate lines beginning
  • with the # character.

New in Portable Brain Workshop 4.5 (Sep 30, 2010)

  • First release with Quad N-Back and other new modes
  • Includes various other improvements

New in Portable Brain Workshop 4.41 (Sep 30, 2010)

  • The size of the field with the FIELD_EXPAND option was decreased slightly.

New in Portable Brain Workshop 4.4 (Sep 30, 2010)

  • Novice Mode was renamed to Jaeggi Mode.
  • Jaeggi Mode will activate certain options to emulate the appearance
  • of the software used in the original study. Two configuration options
  • were added to control this behavior.
  • [Note: to see the new config options, delete your current config
  • file and relaunch Brain Workshop to generate a fresh config.]
  • The data and res directories can now be specified on the command line
  • using the --datadir and --resdir parameters
  • (contributed by Timo Juhani Lindfors ).
  • The daily rollover hour for stats can now be specified in the config file.
  • A bug was fixed where certain trials would not show up in the list
  • if the program was launched between midnight and 4 AM.
  • A setting to skip the title screen was added to the config file.
  • The grid lines and crosshairs can be toggled in the config file.
  • A setting was added to select rounded or sharp corners for the
  • solid-color squares.
  • A setting was added to expand the size of the field to fill the screen.
  • Arithmetic Mode: The acceptable decimal answers can be set in the
  • config file.
  • Three new music clips were added.
  • The Clear Stats key (Control-C) is working again.
