The data were stored in BrainVision Format. The following stimuli were used:

-> R1 � this stimulus should not normally appear � if it does, it is likely a reaction to a goat
-> R2 � true - expected reaction to a sound assigned correctly to an animal (a dog barks or a cat mews)
-> R3 � false - expected reaction to a sound assigned incorrectly to an animal (a dog mews or a cat barks )
-> S1 � standard stimulus (a goat bleats) - non-target the measured participant should not respond
-> S2 � a dog barks - target � should be followed by the R2 marker
-> S3 � a cat mews - target - should be followed by the R2 marker
-> S4 � a cat barks - target - should be followed by the R3 marker
-> S5 � a dog mews - target - should be followed by the R3 marker

-> S11 � a marker that denotes an occurrence of the standard stimulus (non-target) after the S2 stimulus
-> S12 � a marker that denotes an occurrence of the standard stimulus (non-target) after the S3 stimulus
-> S13 � a marker that denotes an occurrence of the standard stimulus (non-target) after the S4 stimulus
-> S14 � a marker that denotes an occurrence of the standard stimulus (non-target) after the S5 stimulus

Note: The S11 - S14 stimuli are typically ignored in the phase of analysis because they could distort the results.

Probabilities of occurrences:
S1 � 70%
S2 � 15%
S3, S4, S5 � 5%


The following files were stored:


Data files:
-> Auditory_ERP_gender_date_id.eeg - a binary file containing raw data

Header files:
-> Auditory_ERP_gender_date_id.vhdr - a text file containing metadata describing raw data in the .eeg file

-> Auditory_ERP_gender_date_id.vmrk - a text file containing markers used in the experiment

Recording Software
For recording and storing the EEG/ERP data, the BrainVision Recorder 1.2 was used. The Recorder was initialized using the following parameters:

1) the sampling rate was set to 1 kHz
2) the number of channels was set to 19
3) the resolution was set to 0.1 �V
