The provided EEG data were acquired from sixteen healthy young adults (age range 22 - 30 years) with no history of neurological, physical, or psychiatric illness. All the participants were naive BCI users who had not participated in any related experiments before. Informed consents were received from all participants.The study has been approved by the Institutional Research Ethics Committee of Nazarbayev University.Scalp EEG was recorded using a 16-channel, active Ag/AgCl electrodes (g.USBamp, g.LADYbird, Guger Technologies OG, Schiedlberg, Austria) with a sampling frequency = 256 Hz. EEG electrodes were positioned according to the International 10-20 system. The right earlobe of participants was used for a ground electrode, whereas the FCz location was used for a reference electrode.The total number of target letters that a participant had to attend was equal to five. These targets were presented in five consequent sequences with an inter-sequence duration (ISD) of two seconds. In total, five repetitions of each target character were made where one repetition (or trial) consisted of a complete set of 12 random flashes of every row and column (six rows and six columns). The inter-stimulus interval (ISI) was set to 150 ms; likewise, the stimulus duration was 100 ms (i.e., the time length a row/col is highlighted). The minimum time between the same target letter highlights was set to 600 ms, also denoted as a target-to-target (TTI) interval. The stimulus onset asynchrony (SOA) was set to 250 ms. The SOA is the time period between the start of one stimulus event, and the start of the next event.
