[DEFAULT]
# Jaeggi-style interface with default scoring model?
# Choose either this option or JAEGGI_MODE but not both.
# This mode allows access to Manual mode, the extra sound sets, and the
# additional game modes of Brain Workshop while presenting the game in
# the more challenging Jaeggi-style interface featured in the original study.
# With the default BW sequence generation model, the visual and auditory
# sequences are more randomized and unpredictable than they are in Jaeggi
# mode. The only effect of this option is to set the following options:
# ANIMATE_SQUARES = False, OLD_STYLE_SQUARES = True,
# OLD_STYLE_SHARP_CORNERS = True, SHOW_FEEDBACK = False,
# GRIDLINES = False, CROSSHAIRS = True, BLACK_BACKGROUND = True,
# WINDOW_FULLSCREEN = True, HIDE_TEXT = True, FIELD_EXPAND = True
# Default: False
JAEGGI_INTERFACE_DEFAULT_SCORING = False
# Jaeggi mode?
# Choose either this option or JAEGGI_INTERFACE_DEFAULT_SCORING but not both.
# This mode emulates the scoring model used in the original study protocol.
# It counts non-matches with no inputs as correct (instead of ignoring them).
# It also forces 4 visual matches, 4 auditory matches, and 2 simultaneous
# matches per session, resulting in less randomized and more predictable
# sequences than in the default BW sequence generation model.
# Different thresholds are used to reflect the modified scoring system
# (see below). Access to Manual mode, additional game modes and sound sets
# is disabled in Jaeggi mode.
# Default: False
JAEGGI_MODE = False
# The default BW scoring system uses the following formula:
# score = TP / (TP + FP + FN)
# where TP is a true positive response, FN is a false negative, etc. All
# stimulus modalities are summed together for this formula.
# The Jaeggi mode scoring system scores uses the following formula:
# score = (TP + TN) / (TP + TN + FP + FN)
# Each modality is scored separately, and the score for the whole session
# is equal to the lowest score of any modality.
# Default: False
JAEGGI_SCORING = False
# In Jaeggi Mode, adjust the default appearance and sounds of Brain Workshop
# to emulate the original software used in the study?
# If this is enabled, the following options will be set:
# AUDIO1_SETS = ['letters'], ANIMATE_SQUARES = False,

Message("""Warning: Could not load AVbin. Music disabled.
This is usually due to Windows Data Execution Prevention (DEP). Due to a bug in
AVbin, a library used for decoding sound files, music is not available when \
DEP is enabled. To enable music, disable DEP for Brain Workshop. To simply get \
rid of this message, set USE_MUSIC = False in your config.ini file.
To disable DEP:
1. Open Control Panel -> System
2. Select Advanced System Settings
3. Click on Performance -> Settings
4. Click on the Data Execution Prevention tab
5. Either select the "Turn on DEP for essential Windows programs and services \
only" option, or add an exception for Brain Workshop.
Press any key to continue without music support.
