Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for synchronizing neuroelectric measurements with diagnostic content presentation by performing actions that include causing a presentation system to present diagnostic content a user, where the diagnostic content includes: a first content frame prompting the user to perform a physical task, a second content frame including electroencephalogram (EEG) synchronization content, the second content frame sequentially following the first content frame, and a third content frame indicating an outcome of the physical task, the third content frame sequentially following the second content frame. The actions include obtaining, from a brainwave sensor, EEG signals of the user during presentation of the diagnostic content. The actions include providing the EEG signals as input features to a machine learning model that is trained to predict a psychological state of the user based on the EEG signals.
