Abstract
Event-related potential (ERP) studies have associated the recovery of information from personally experienced past events, or episodic retrieval, with two ERP effects: a parietal effect and a frontal effect. These effects have been repeatedly found using emotionally neutral words [1], emotionally neutral pictures of objects [2] and, more recently, with emotionally negative words [3]. In the present study, we investigated the lateralization of these effects during the recognition of happy and neutral faces. The parietal effect refers to the nding that compared with ERPs for correctly rejected new words, ERPs for correctly recognized old words are more positive over parietal scalp regions [1]. This effect has been attributed to hippocampalcortical interactions during episodic recovery. The parietal effect is usually left lateralized, which has been attributed to the verbal nature of the materials employed in most studies [1,3]. However, the parietal effect was also
