Neural correlates of aggression in schizophrenia: An event-related potential study using the competitive reaction time task

Figure 1 Schematic illustration of the competitive reaction time task. Participants were instructed to play against the opposing participant who was in another room. The player who responded faster won. Before each trial, both participants and their opponents were provided with the option to select the punishment (volume: 0-85 dB; duration: 0-5 s) that the opponent would receive in case of losing the trial. In the reaction phase, both players were asked to press the space key as quickly as possible when a green rectangle turned to red. The screen showed a smiling face when the participants won, and a crying face when the participants lost and received noise punishment. ms: Milliseconds.
