- 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 µV
