Abstract:

ERP technique helps much in emotion studies. These studies usually recruited healthy peopleor individuals with mood disorders as research subjects. The variety of the ERP components, such as theP1, N1, and P300, elicited by visual andPor auditory stimuli were observed. This article reviewed anddiscussed some questions of ERP studies of emotion, such as the relationship between emotion and atten2tion, memory and decision2making, and the lateralization of emotion, and so on. Research results suggestthat emotion can enhance attention and novel emotional stimuli can be detected more easily. In normalsubjects, emotional words can arouse stronger old2new effects than neutral words. Depressive patientscannot present the same effects as the normal ones, but their recognizing achievements can be improvedby emotional words. When studying the influence of emotion upon decision2making, researchers observedchanges of medial frontal negativity (MFN). The lateralization of brain functions also exists in emotionalactivities.

Key words: emotion, ERP (event-related potential), attention, memory, decision-making, lateraliza-tion
