In this dataset, 55 novice BCI users participated in a two-class left versus right hand motor imagery BCI task. There was one session with four runs of each 40 trials: one calibration run and three runs where feedback was provided.
Cognitive and Psychological tests that were administered:
* Demographics
* Five Factor Personality Inventory
* Vividness of Visual Imagery
* Affinity for Technology Interaction Scale
* Design Organization Test
* Mental Rotation Test
* Questionnaire of Current Motivation
The classification errors as well as the raw EEG is provided.

Method:
Electroencephalography signals were recorded from 16 electrodes according to the 10-20 international system (F3, Fz, F4, FC1, FC5, FC2, FC6, C3, Cz, C4, CP1, CP5, CP2, CP6, T7, and T8). A reference electrode was set on the right earlobe and a ground electrode on AFz. EEG signals were amplified by a g.Nautilus amplifier (g.tec Medical Engineering, Austria).
The online classification errors were calculated by g.BSanalyze, which is a Simulink-based high-speed online processing package (g.tec Medical Engineering, Austria).
Questionnaires were administered using Qualtrics software (Qualtrics, Provo, UT, United States), The Design Organization Test was conducted on paper and the Mental Rotation Task was conducted via psychometric toolboxes in Matlab.
Universe:
Participants were BCI novices (36 females, 21 males, MAge = 20.71, SDAge = 3.52) recruited from Tilburg University students. Subjects were all right-handed with (corrected to) normal vision.
Country / Nation:
