A multi-functional event-related potential (ERP) experiment chamber comprises an experiment chamber (1) and a laboratory (2) arranged neighboring the experiment chamber (1). The experiment chamber (1) is an experiment chamber having conventional electromagnetic shielding, and a device (14) for air return in the experiment chamber, an independent ground wire and power device, a background music player (11), an infrared video monitoring device (12), a chamber voice intercommunication device, an electric curtain control device (9), a lighting device (13) controllable from both inside and outside of the experiment chamber, an oxygen negative ion supply device (15), and an experiment table and chair are mounted or placed in an interior of the experiment chamber (1). A control console (5) is provided within the laboratory (2) to separately control the background music player (11), infrared video monitoring device (12), chamber voice intercommunication device, electric curtain control device (9), and lighting device (13) controllable from both inside and outside of the experiment chamber. The present invention creates an environment meeting various specific requirements for an ERP experiment with a smaller space, thereby facilitating improvement of EPR experiments and promotion and applications of ERP technology.Une chambre dexpérimentation potentielle multi-fonctionnelle associée à un évènement (ERP) comprend une chambre dexpérimentation (1) et un laboratoire (2) agencé de manière adjacente à la chambre dexpérimentation (1). La chambre dexpérimentation (1) est une chambre dexpérimentation ayant un blindage électromagnétique classique, et un dispositif (14) pour le retour dair dans la chambre dexpérimentation, un fil de mise à la terre indépendant et un dispositif de puissance, un lecteur de musique de fond (11), un dispositif de surveillance vidéo infrarouge (12), un dispositif dintercommunication vocale de la chambre, un dispositif de commande de rideau électrique (9), u
