The Early Repetition Effect: Reliability and Methodological Influences Grit Herzmann (Humboldt University Berlin)
When a familiar face is seen twice in a repetition priming paradigm an increased negativity at temporal-parietal and a increased positivity at frontal electrodes around 250 ms after stimulus onset is seen in event-related potentials when compared to unrepeated familiar faces. This effect is called the early repetition effect, N250r or ERE. It increases in amplitude from unfamiliar, to publicly familiar and is largest for personally familiar faces. The aim of the present study was to assess whether newly learned previously unfamiliar faces would elicit an ERE and to compare it to repetition effects to newly learned names under comparable conditions. 40 unfamiliar faces and unfamiliar person names were learned separately to criterion without any other context information. One week later recognition of these stimuli was tested. The obtained ERE for faces showed the same characteristics as the ERE previously observed to personally and publicly familiar faces. Some differences emerged between the EREs for faces and names, indicating domain specificities of the underlying processes. Preliminary analyses indicate promising retest reliabilities at least for the ERE. |
