BrainWorkshop 5

PS: If you appreciated this work, please star the repository. It helps others find this repository

What is this?

This is a fork of the popular brain training software BrainWorkshop

Since there has not been a release in 3 years, I decided to get it working on Python 2+3 in additon to making many changes and improvements.

Version 5 is technically in Beta, although it is expected to be more stable compared to the original project and work with modern Python and Pyglet

Downloads

• Windows: https://github.com/brain-workshop/brainworkshop/releases

New in this release:

• Elements on the screen scale depending on the window size, making it much more usable if you have a hidpi monitor.
• Using a widescreen resolution causes items on the screen to be placed/scale properly
• Fullscreen mode sets the resolution of the screen automatically
• Font size scales based on window size
  • Positioning of items also scales with window size
  • Window position and font size are determined with one function to do scaling, thereby making it easier in the future to make adjustments
• Set fonts differently for serif and for monospace fonts, eventually to allow them to be configurable.
• Now compatible with Python 3
  • Fixed issues with at least three modules not loading. This was due to being renamed or their semantics changing. Fixed in a way to maintain Python 2 compatibility.
  • Fix alignment of the polygons/icons in the grid due to changes to division in Python 3
• Compatible with both Python 2 and Python 3!
• Fixed crash with text.Label not recognizing halign; use align instead since halign is deprecated. Though to avoid breaking anything, we try align first and if that fails we fall back to using halign
• Fix many more crashes and issues of Brain Workshop failing to launch

Notes:

• You need pyglet installed for this to work.

Python 3

If you are having issues launching BrainWorkshop even if you have pyglet, future, past and libfuturize modules installed, follow these steps first:

1. Copy the following folders into the brainworkshop folder: past, future and libfuturize. You can get those here: https://github.com/PythonCharmers/python-future
2. Copy the pyglet module into a pyglet folder. You can get pyglet here: http://www.pyglet.org/

Python 2

• You need pyglet, urllib3

Change Log:

4.8.1:

• Bugfix release. Text shows up properly on Menu screens with BLACK_BACKGROUND=True. Bug in graphing code fixed which caused some stats.txt files to not be graphable. Option added to remove post- session feedback (requested by a researcher). Daily session counter fixed. Trials per session at startup fixed.

4.8:

• 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, like thus: ABCDEFGHIJKLMNO ---CBAFEDIHGLKJ
• Full 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.

4.7:

• 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.

4.5:

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

4.41:

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

4.4:

• 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 timo.lindfors@iki.fi).
• 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.

4.3:

• Variable n-back levels can be used with any game mode by pressing V in the Choose Game Mode screen.
• Sounds for the auditory n-back task can be selected by pressing S.
• Letter N-Back renamed to Combination N-Back.
• New Morse Code sounds can be used with any n-back mode. For the ultimate challenge try using Morse Code with Dual, Tri or Quad Combination N-Back. Press J to open a Morse Code reference page.
• Average n-back indicator will only count sessions specific to the current game mode.
• Progress graphs now start from 1.0 on the vertical axis to give a better overall picture.
• The cutoff for daily averages is is now 4:00 AM instead of midnight.
• Music and applause is stopped when entering the progress graph to avoid sound skipping. (The sound may not stop in Linux due to driver limitations.)
• Config file changes: The starting N-Back mode and game speed is now separately adjustable for each game mode, and some colors can be customized. Variable N-Back can also be set as default. [Note: to see the new config options, delete your current config file and relaunch Brain Workshop to generate a fresh config.]

4.22:

• There's a new title screen.
• Launching in Novice Mode will no longer cause a crash.
• Progress graph: date axis will no longer skip days.
• Progress graph: data points are now indicated with a dot.
• Num pad should now work properly with Arithmetic N-Back modes.
• Difficulty of Dual Variable N-Back has been increased slightly.

4.2:

• Added new mode to stretch working memory: Dual Variable N-Back. The n-back level is displayed in the center and changes randomly every 3 seconds.
• Added single-task n-back modes: Position N-Back and Audio N-Back.
• Default config file is no longer packaged with the download so upgrading to this version won't overwrite existing configuration settings. The config file config.ini will be created if necessary when BW is launched for the first time.
• OpenAL is now the default sound driver in Linux if available. If you're having sound problems, it may help to install the python-openal package.
• There's no longer any need to install pyglet on Mac OS X or Linux. It's now included with the source distribution.

4.12:

• Fixed level increase threshold in Novice mode
• Novice mode now generates 4 visual matches, 4 audio matches and 2 simultaneous matches, matching the formula used in the original study.

4.11:

• Fixed level decrease threshold in Novice mode
• Added a configuration option to use the pre-4.1 flat squares
• Two changes to Novice Mode to eliminate the last of the differences compared to the original study protocol:
  1. Exactly 6 position and 6 audio matches are now generated each session
  2. The score for the session is set as the lowest of the two individual modality scores (visual & audio).

4.1:

• The squares in Dual & Triple N-Back have a new look.
• Individual scores for each input category (position, sound, etc) are shown in the graph screen.
• The number of sessions below 50% required to trigger a level decrease has been changed from 1 to 3.
• New piano sounds are available in the config file to test your tonal memory.
• Pressing the ESC key during a session will return you to the main screen instead of quitting the program.

4.04:

• Added the division operation to the Arithmetic N-Back modes. Use the period key '.' to insert a decimal point. Each of the operations (add, subtract, multiply, divide) can be turned off or on in any combination in the config file.
• Fixed a bug where if you had just advanced to a new level and quit BW, the next time you restarted you would be back at the previous level.
• Added config option to play music in Manual mode.

4.03:

• Added new number sounds (0-13). Either the letters or the numbers will be chosen randomly at the start of each session.
• The female voice sounds are now selected by default.
• Added two new game modes, Dual Arithmetic N-Back and Triple Arithmetic N-Back. Press N from the main screen to access the extra game modes.

4.02:

• Fixed sound driver selection in Linux.
• A few minor changes related to Arithmetic N-Back mode.

4.0:

• New game mode: Arithmetic N-Back (see tutorial for details)
• Optional Novice mode (aka BT mode) emulates the original study protocol.
• New NATO Phonetic Alphabet sounds (alpha, bravo, charlie, etc). The old sounds are still available as an option.
• Keep track of your daily progress with the new graphing feature.
• Export your history of daily n-back averages to a text file for easy pasting into a spreadsheet.
• Adaptive level-changing model ensures you're always playing at the right level.
• Keyboard keys can now be redefined.
• Feedback for missed cues is displayed.
• Feedback can be turned off in the config file if desired.
• Text can be hidden during gameplay to reduce distractions.
• Optional full-screen mode for a larger, distraction-free playing field.
• Optional black background reduces eye strain.
• Easy config file provides access to configuration options.

3.1:

• Enabled high performance VBO (vertex buffer object). If you get a MissingFunctionException, use the --novbo command line parameter to launch Brain Workshop.
• Changed preferred sound driver to ALSA on Linux.
• Converted letter sounds to 44.1 KHz to alleviate crackling problem on certain sound hardware.

3.01:

• When first loading, if the last session completed was in Standard mode, Brain Workshop will start at the same n-back level.
• Only today's sessions are loaded in the history chart.

3.0:

• Three consecutive scores of >=80% are now required to advance levels, as indicated by the grey/green squares in the top left corner. A grey square will turn green if a >=80% score is achieved and a green square (if any) will turn grey if the score is below 80%. Once both squares are green and another 80% is achieved, the level increases. A 100% score will cause an instant advancing.
• The entries on the session history chart will turn green if the session is >= 80%. The chart now displays in a variable-width font.
• Added the time.sleep() workaround to reduce CPU usage on OS X. Disabled Vsync to eliminate an error message on certain machines.
• New columns have been added to the stats.txt file, including individual percentage scores for the six input types. Please see Readme-stats.txt in the data directory for details.

2.7:

• Added a new column in the stats file: 0 = Standard mode, 1 = Training mode
• one new music clip added
• Added an encouraging message if you get below 40%

2.64:

• Lowered level advance threshold to 80%.
• Added a workaround for pyglet.gl.lib.MissingFunctionException which occurs on certain video cards.

2.63:

• Fixed a bug causing 100% CPU utilization.
• Fixed a crash caused by the music clip feature.
• Reduced startup time and memory footprint.

2.62:

• Contribution to the n-back average is now calculated like so: (nback - 1) + percentage / 100 This means the average n-back level for a single 4-back session with a score of 50 percent will now be 3.5 instead of 2.

• Fixed a bug in the input feedback that would show correct responses as incorrect (this did not affect stats).

• Added more music clips and adjusted the length and volumes of the existing ones.

2.6:

• Added color feedback on input. The input labels ('A: position' etc) will turn red for incorrect, green for correct and blue if there haven't been enough trials yet.

2.5:

• Fixed bug where a bogus stats entry would be created under certain conditions when switching from Standard to Training mode.
• Removed the need for Tkinter on Linux and OS X.

2.4: Added music clips which play when certain scores are achieved.

2.3:

• Added a Sessions Today indicator which shows the total number of sessions completed this calendar day. Useful for tracking progress on your 20 session per day training quota.
• Added possibility of different stats files on the command line. Give each person in your family a separate desktop icon! example: brainworkshop.exe --statsfile fred.txt brainworkshop.exe --statsfile mary.txt
• Brain Workshop now starts in Standard mode. This enforces certain settings for number of trials and time per trial, making it easier to compare scores. Currently these are specified as follows: All modes are 20 trials per session. Dual N-Back: starts with 2-back, 3 seconds Triple N-Back: starts with 2-back, 3 seconds Dual Letter N-Back: starts with 1-back, 3 seconds Tri Letter N-Back: starts with 1-back, 4 seconds Quad Letter N-Back: starts with 1-back, 4 seconds
• Fixed a bug in the average n-back calculation
• Changed stats file format from tab-separated to comma-separated. Old stats files will still load successfully.

2.2:

• Session stats are now output to the file data\stats.txt
• Previous stats are loaded upon launch.
• Added an option to clear stats (this does not affect stats.txt)
• Average N-Back level is calculated for the last 20 sessions. The contribution of a particular session is calculated: Contribution = (N-back level) * (Percentage score) / 100 Average is calculated as: Average = (sum of contributions) / (number of sessions)

2.1:

• Added three new challenging game modes: Dual Letter N-Back, Tri Letter N-Back, Quad Letter N-Back
• Adjusted level advance threshold from 100% to 90%
• Adjusted "applause" threshold from 80% to 70%

2.0:

• Applause sound now plays when a score of 80% is achieved
• Version check is now performed on launch
• Added a workaround for the pyglet.gl.ContextException error which occurs on certain video cards
• Added a more descriptive error message in case an old version of pyglet is installed
• Fixed cosmetic issue with the session history label on Linux
