Abstract(englisch):
Event-related potentials (ERPs) were obtained from an identity priming task, where a green target had to be selected€against a superimposed red distractor. Several priming conditions were realized in a mix of control ( CO), negative€priming (NP), and positive priming (PP) trials. PP and NP effects in reaction times (RTs) were significant. ERP results€conceptually replicate earlier findings of left-posterior P300 reduction in PP and NP trials compared to CO. This ERP€effect may reflect the detection of prime-probe similarity corresponding to the concept of a retrieval cue. A novel€finding concerned amplitude increase of the frontal late positive complex (LPC) in the order NP, CO, and PP. NP€therefore seemed to induce brain activity related to cognitive control and/or memory processes, with reduced LPC€amplitude indicating effortful processing. Overall, retrieval-based explanations of identity NP are supported. (DIPF/Orig.)
